Why choose a heat pump?

In the context of ever rising energy costs and climate change, every household is in need of a heating technology that is future-proof, cost-effective and independent of fossil fuels.

Using nature's energy

Heat pumps make a significant contribution towards solving the problems associated with increasingly scarce and evermore expensive energy resources – supplying more energy than they consume by tapping into the freely available, inexhaustible solar energy stored in the earth, the ambient air or water and converting this for use in a heating system.

In fact, up to 75% of the energy needed by the heating system is extracted from the environment, so the only energy required is electricity needed to drive the heat pump compressor.

Put another way, for every 1kWh of electricity used to run the heat pump, up to 4kW of useful heat is provided, giving the heat pump an efficiency of up to 400%.

A low carbon heating solution

Whenever fossil fuels such as gas or oil are burnt, carbon dioxide is released. CO_2 is the principle contributor to the greenhouse effect which is leading to long term climate change.

However as heat pumps extract as much as 75% of their heating energy from the environment, building carbon emissions for heating can be reduced by as much as 50% compared with gas fuelled heating systems.

This is an obvious benefit when considering building regulations Part L compliance, planning obligations requiring minimum contributions from renewable energy and EcoHome/Code for Sustainable Homes ratings.

Low running costs Low ownership costs

The considerable contribution from renewable energy sources also helps to provide running cost savings over fossil fuelled heating systems and arguably more importantly, future proofs the system against future energy price increases.

But fuel costs are only part of the story. Unlike gas and oil based systems, heat pumps require no costly regular maintenance or annual safety inspections. And because a heat pump has a reasonable life expectancy of 20 – 25 years, typically twice that of a boiler, the investment costs can be recovered over a longer period meaning the ownership costs over the working life of the system are demonstrably lower.

The global challenge

Climate change is the greatest threat facing the planet, with rising temperatures causing more droughts, floods and storms causing sea levels to rise.

In the last 20 years, use of the Thames Barrier (designed to protect London from flooding) has risen from once every two years to six times a year.

According to the latest figures from the Intergovernmental Panel on Climate Change (IPCC), 11 of the last 12 years rank in the 12 warmest years since 1850 and 2005 was the hottest year on record. The impacts of weather related disasters are also increasing two to three times more rapidly than impacts due to earthquakes.

Most scientists agree that climate change is largely due to human activity, mainly the increased use of fossil fuels. The main human influence on the global climate is likely to be emissions of greenhouse gases such as carbon dioxide ( CO_2 ) and methane.

What difference can we make?

Emerging nations such as China and India are today consuming more and more energy to fuel their enormous economic growth, so what difference can a tiny island like the UK make?

Indeed if the UK became 100% zero carbon tomorrow, it would take China less than 3 months to replace the UK's carbon emissions.

World map silhouette in green, showing continents and oceans (no text or labels)

However, carbon emissions per capita in the UK are one of the highest in the world – in fact if every nation had such high emissions per head of population, global emissions would increase 3-fold.

So the UK has a responsibility to demonstrate to the developing nations of the world that it is possible to achieve economic growth while reducing its carbon emissions and environmental impact.

Planning for the future

Currently we all have the freedom to choose whether or not to voluntarily install greener technologies to reduce our homes' or businesses' carbon footprint. Some experts predict that greener technologies will be compulsory through legislation in the near future as has the recycling of our rubbish.

The sooner you switch, the sooner you can start to save money and the planet.

Harnessing nature's energy

Our environment is full of energy, even at sub-zero temperatures there is plenty of energy available.

Heat pumps use conventional refrigeration technology to extract the sun's energy stored in the environment and raise it to a temperature suitable for heating purposes.

This method even works in the middle of winter at temperatures as low as -25°C.

Ground source heat pumps extract heat from the earth all year-round via ground heat collectors buried beneath the ground.

Trusted technology

Using nature's energy efficiently

Heat pumps are among the most efficient heating and hot water systems available today. Approximately 75% of the energy needed for heating comes from the environment. This means that for every 1kWh of electricity used to power the heat pump compressor, between 3 and 4 kWh of heating energy are produced, giving the heat pump an efficiency of 300 – 400% or higher.

The heat pump's "efficiency" is known as its "Coefficient of Performance" (CoP). This is simply a ratio between the proportion of the total energy supplied that can be extracted from the environment and the amount supplied by electricity to run the heat pump compressor. The higher the CoP, the more "free" environmental energy the heat pump is using!

Heat pump system components

A heat pump heating system consists of 3 components: the heat source, the heat pump itself and a heat distribution and storage system.

Heat pumps are able to produce more energy than they consume by using the conventional refrigeration cycle to absorb heat from the environment and raise it to a suitable level for heating.

1 75% of the energy is taken from the environment i.e. the air or ground and transferred to the heat pump.

3 The energy from the air or ground is transferred to the refrigerant inside the heat pumps evaporator. This causes the temperature of the refrigerant to rise and change state from liquid to gas.

5 A heat exchanger (condenser) then extracts the heat energy from the hot refrigerant to heat water for central heating, underfloor heating or domestic hot water.

2 25% of the energy is sourced from the national grid in the normal way of supplying your electricity. This is used to operate the heat pump but with very low consumption.

4 The refrigerant gas is then compressed, using an electrically driven compressor, reducing its volume but causing its temperature to rise significantly.

6 After giving up its heat energy the refrigerant turns back into a liquid and is able to absorb energy from the environment, allowing the cycle to begin again.

Financial incentives

Grants and Funding

The era of grant funding schemes for heat pumps is beginning to come to an end, however as the Government endeavours to meet its target of 15% of total UK energy consumption being generated from renewable source by 2020, schemes are being put in place to encourage the uptake of renewable heat technologies.

Renewable Heat Incentive (RHI)

The Renewable Heat Incentive (RHI) announced in March 2011, is aimed at encouraging people to install renewable heating technologies and is the first financial support scheme for renewable heat in the world. Administered by OFGEM the scheme has been split in to two phases:

Phase 1

This phase of the scheme opened for applications on November 28, 2011 and is focussed on the non-domestic sector (industrial, business and public sector) as it accounts for 38% of the UK's emissions. For the domestic sector a one off incentive has been put in place, the Renewable Heat Premium Payment (RHPP) to provide householders with financial support to install renewable heating technology. Currently only the technologies listed within the EU Renewable Energy Directive are supported. As listed below:

• solid biomass and solid biomass contained in municipal waste (including CHP),
  • ground and water source heat pumps,
  • geothermal (including CHP),
  • solar thermal (at capacities of less than 200 kWth),
• biogas combustion (except from landfill gas but including CHP; at capacities of less than 200 kWth) biomethane injection.

Note: Air source heat pumps are not currently supported.

Participants also need to meet several other eligibility requirements which are explained in the Guidance document. These include demonstrating that the heat is used for an eligible purpose, that metering arrangements are appropriate, and that grants have not been received for certain purposes.

The tariffs will be paid for 20 years to eligible technologies that have been installed since 15th July 2009 with

payments being made for each kWh of renewable heat which is produced. Once in the scheme the level of support an installation will receive is fixed and adjusted annually with inflation.

Phase 2

The second phase is likely to see the scheme expanded to include additional technologies as well as long term support for house holders. DECC expects that Phase 2 will be up and running by Summer 2013 which represents a significant slippage from the original intended start date so to accommodate this slippage a second phase of RHPP has been put in place, effective from 2 April 2012.

Consultations are taking place looking at the inclusion of further commercial technologies such as Air Source Heat pumps and budget control measures; an interim budget control mechanism for Phase 1 and for Phase 2, a longer-term flexible degression-based cost control mechanism to automatically reduce tariffs should spending against the overall budget or uptake of certain technologies exceed forecasts.

Dimplex Renewable Energy Finance

Dimplex Renewable Energy Finance has been specifically designed to help not-for-profit organisations including local authorities, schools and housing associations overcome the need for initial capital investment when installing heat pump systems.

The scheme is designed to provide a solution for organisations looking to implement renewable energy technologies but for whom the initial capital outlay, even where grants are available, could make going ahead with the project an impossibility, by allowing investment costs to be repaid over a period of years funded through the savings in energy costs the heat pump will provide.

Benefits of the scheme include:

• Can be used in place of grants to cover entire project costs
• Project costs covered in full with no up-front capital outlay
  • Investment costs recovered from energy cost savings on an ongoing basis
• Allows project schedules to be accelerated by removing budgetary constraints
• Flexible payment schedules and accounting structure based on client needs

Reduced Energy Costs

In addition to reducing a property's carbon footprint the installation of a heat pump can also bring financial rewards in the form of lower energy bills and potential income through the Renewable Heat Incentive scheme.

Air source heat pumps

Even cold air is full of energy and Dimplex air source heat pumps use the freely available heat in the ambient air to provide efficient heating and hot water at air temperatures as low as -25°C.

Because the source of heat – the air – is abundantly available all around us, air source heat pumps have the advantage of low installation costs and minimal space requirements, while relatively mild winter temperatures in the UK mean excellent levels of efficiency and performance are achieved throughout the year.

Benefits of the outside air as a heat source

• Can be utilised all year round between -25°C and +35°C
  • Always available and inexhaustible source of heat
  • No requirement for the cost and land area of ground collectors
• Ideal for new build or retro fit applications, especially where space is limited
• Can be used for heating, cooling, domestic hot water and swimming pools

Air source heat pumps – benefits of the UK climate

Compared with central Europe (where air source heat pumps are already very popular), the UK has a relatively moderate winter climate.

With average winter temperatures of around 5^ C, seasonal co-efficients of performance comparable with ground source heat pumps are achievable, without the additional cost of expensive ground loop systems having to be installed.

Dimplex heat pumps score for McCarthy & Stone

McCarthy & Stone, the UK's largest builder of retirement homes, took the lead in energy savings by installing Dimplex heat pumps at a development of 41 apartments in Clevedon, Somerset and achieved level 3 of the Code for Sustainable Homes. Three 28kW Dimplex air source heat pumps provide a communal system, servicing the entire block, with each flat having its own metering and separate hot water cylinder.

Domestic air source heat pumps

Inverter driven air source heat pumps

Dimplex Air-Eau inverter driven air source heat pumps deliver market leading energy efficiency and performance with achievable CoPs of up to 4.7. With a range of inverter models with outputs from 6 – 16kW, Dimplex can provide a solution for most domestic applications from small, well-insulated new build homes, to retrofits in existing homes which have higher heat demands.

Easy to install, due to the range's monobloc configuration, the Air-Eau is the ideal choice for new developments looking to reduce CO_2 emissions, social housing refurbishment projects to tackle fuel poverty and the replacement of oil/LPG systems in larger private homes.

At the heart of the Air-Eau heat pump is a variable speed, inverter controlled compressor, which allows the heat levels delivered to be matched closely to the heating requirements of the building, as ambient temperatures change. This means that in cold weather heat pump capacity is maintained, eliminating any need for supplementary back up heating, while at warmer air temperatures, heat pump output can be reduced, helping to improve efficiency.

AIR eau

Air-Eau/LA MI

The Dimplex Air-Eau range of inverter-driven air source heat pumps are designed to match output to varying heating demand. With achievable CoPs of up to 4.7, the Air-Eau provides one of the most advanced, efficient and high performance air source heat pump ranges available.

Employing an inverter driven compressor to maximise heat pump efficiency enables the Air-Eau range to modulate the heat pump output to match the

Domestic air source heat pumps

Dimplex domestic air source heat pumps are designed specifically for the UK climate and are constructed to withstand the best and worst of the British weather, with powder-coated metal casings and a stainless steel base frame. Installed outside the property, close to the building with a minimum 30cm clearance, they are ideal in situations where internal space is at a premium.

With low noise levels and outputs ranging from 8 to 16kW, the Dimplex domestic air source heat pump models provide a range of cost effective heating and hot water solutions for small to large properties.

Our domestic air source heat pumps are designed to deliver 100% of the heating and hot water demand, with the heat pump itself typically sized to provide at least 99% of the annual heating requirement. To minimise investment costs, it is normal to provide the remaining energy demand from a supplementary heat source, most commonly an electric immersion heater, however in retro-fit applications it is also possible to run the heat pump in parallel – “bivalent” mode – with an existing boiler.

Commercial air source heat pumps

High output and high temperature air source heat pumps

The Dimplex range of high output air source heat pumps are ideal for multiple occupancy properties such as flats and apartments when installed as a centralised heat pump system. With models ranging from 20-28kW our high output air source heat pumps are able to provide an efficient, building-wide heating solution.

Employing optimised twin compressor operation this high output range can also cater for buildings with high heat consumption such as offices, schools, hotels or retail outlets.

Improving a buildings thermal insulation can often be enough to allow the heating system to be operated at the low temperatures normally associated with heat pumps. However higher water flow temperatures are sometimes needed where high volumes of hot water are required at temperatures of 60^ C or higher, or where the heat pump is intended for use in older buildings with existing radiator systems.

The Dimplex range of high temperature air source heat pumps can easily fulfil these requirements by providing variable water flow temperatures of up to 65°C.

Parallel operation for higher total capacity

Multiple Dimplex heat pumps can be connected together in parallel to provide a highly cost effective solution where very high capabilities are required. The WPM heat pump manager controls and optimises performance of the system.

Ground source heat pumps

Drawing as much as 75% of the energy needed by the heating system from freely available, inexhaustible solar energy stored in the ground, Dimplex ground source heat pumps are available in an extensive range of models types and capacities suitable for either domestic or commercial applications.

Due to highly stable temperatures below the earth's surface, ground source heat pumps provide high levels of efficiency for space and water heating all year round.

Benefits of the ground as a heat source

• Consistent temperatures below ground throughout the year provides a high Co-efficient of Performance.
• Can be used for heating, domestic hot water and swimming pools.
• Borehole systems can be used for either passive or active cooling (see page 33).

At just 1m below the surface, the earth provides a stable source of heat throughout the year.

At depths of 15m or more, the earth provides a constant 10^ C temperature.

Installation

The earth stores an enormous amount of solar energy from both solar radiation and rainfall. To extract this energy, ground collectors consisting of flexible poly ethylene pipes are buried in the earth, either horizontally or vertically. A mixture of water and anti-freeze is then circulated through the pipe loops, attracting the heat energy and transferring it to the heat pump.

Horizontal ground collectors

If a large enough land area is available, horizontal ground collectors provide an effective method of extracting heat from the ground.

The pipework is buried at a depth of approximately 1.2m and spaced 0.75m apart. The land area required is

Architectural rendering of a two-story residential house with curved roof and adjacent courtyard (no text or symbols)

dependent on both the capacity of the heat pump and heat conductance of the soil type in which the pipes are buried.

As a space saving alternative to horizontal collectors, slinkies, consisting of coiled pipes buried in a trench can be used.

Vertical boreholes

If land space is limited the ground collectors can be installed vertically in a borehole, drilled up to 100m deep in the ground.

Multiple boreholes are commonly used in large installations where very high levels of heat extraction are required.

Heat pumps in action

Dimplex heat pumps have been installed in a wide variety of applications – two are featured here, but more are available on our website.

Housing Association bungalows convert to Dimplex

Stafford & Rural housing association has fitted Dimplex ground source heat

pumps into a refurbishment project of nine warden-linked bungalows at Synnerton, Staffordshire, with five of the properties taking part in a year long survey by the EST to monitor heat pumps in real-life installations.

One of the key considerations when replacing the system was fuel poverty as economic heating was very important to its tenants. The housing association was also looking for something that was future-proof, cost effective with no costly bills or annual inspections. Three suppliers were considered by an assessment panel which included 3 tenants with Dimplex selected because of the overall package they could supply.

Reversible heat pumps

Innovative heating and cooling

Apart from an efficient heat pump heating system, summer time cooling of well-insulated new buildings is becoming increasingly important to achieve a comfortable environment. Solar gain, higher levels of insulation and increasingly warm summer temperatures all lead to a rising demand for cooling systems. Dimplex offers an innovative, energy efficient concept for all types of heat sources to also utilise water-bearing heating systems for cooling purposes.

Reversible heat pumps for active cooling

In winter the heat pump functions as an energy efficient heating device and extracts the required energy from the environment. By reversing this process the heat pump can be operated to provide cooling, extracting heat from the building and transferring this to the environment via the heat pump refrigerant and compressor.

Waste heat recovery makes it possible to also produce domestic hot water extremely efficiently during the cooling process, while returning waste heat to the ground (using a ground source heat pump) effectively stores the energy for use later in the year when needed for heating.

The entire system is controlled by the heat pump manager.

Passive cooling with borehole heat exchangers or ground water.

Deeper ground layers have constant temperature levels of around 10^ C all year round. This allows ground source heat pumps installed with vertical borehole collectors to be used to provide 'passive' cooling, by transferring excess heat from the building to the ground via the collector in the summer months.

This is achieved with the addition of a retro-fi ttable passive cooling unit, controlled by an additional cooling controller, which communicates with the heat pump manager to enable a combination of heating and 'comfort' cooling in a single system.

Domestic hot water can still be provided in parallel to the cooling operation as the heat pump compressor is not active in the passive cooling mode.

Depending on the type of heating system installed in the building, cooling can be provided in one of two ways:

Silent (active) cooling via surface heating systems

In summer, the heating surfaces in floors, walls and ceilings are activated for cooling by passing cooled water through them. Large cooled surfaces cool the rooms to a comfortable temperature without draughts or air movement.

Dynamic cooling via fan convectors

Integrated ventilators guide the indoor air to a heat exchanger, which heats or cools the air according to need. Multi-level controllable air recirculation guarantees short response times and high transmission capacities.

Heat pump

manager

Everything is under control

Two heat generators and three heat consumers; the heat pump has everything under control

The heat pump manager monitors the operation of the heat pump and provides all the functions of a modern heating regulation system, including remote diagnostics and time programmes for heating and hot water preparation.

The heat pump, heating and hot water pumps, mixer motor and any supplementary heating sources are all automatically activated by the WPM manager. For reversible heat pumps both heating and cooling modes are managed by the same controller.

System integration with existing systems

The WPM controller also allows Dimplex heat pumps to be efficiently integrated in 'bi-valent' mode with existing systems. When combined in parallel with an existing boiler, the heat pump manager regulates the boiler in accordance to need and ensures that no excessive temperatures can enter the heating system.

This way, for example, a filled oil tank can be used up before converting to heat pump only operation later on, or provide the ability for the heat pump to manage the base heating load with supplementary support from an existing gas boiler. Such strategies provide an excellent opportunity for the installation of heat pumps in existing homes and buildings.

Integration with other renewables

For optimal integration of renewable heat sources, the heat pump manager offers an operating mode developed especially for purpose. Thermal solar energy systems or biomass boilers feed into a renewable cylinder fitted with an additional heat exchanger which, at a sufficient temperature level, gives priority to this energy for heating or hot water, over riding the operation of the heat pump.
