Frequently Asked Questions - VPD 150 Nibe

How does the Nibe VPD 150 heat water?

The VPD 150 uses a heat pump to extract heat from the surrounding air, which is then transferred to the water in the tank. An electric heating element provides backup when needed.

What is the recommended maintenance schedule?

Clean the air filter annually. Check the magnesium anode every 2 years and replace if worn. Test the pressure relief valve yearly.

Can the VPD 150 be installed in a cold room?

It should be installed above freezing. The unit has frost protection down to -20°C, but efficiency drops at low temperatures.

What is the maximum hot water flow rate?

The flow rate depends on temperature rise. At a 45°C rise, it can deliver about 10 liters per minute continuously.

How do I reset the high-limit thermostat?

Press the reset button located behind the front cover after the unit cools down. If it trips again, contact a service technician.

Is the VPD 150 energy efficient?

Yes, with a COP of 3.4 it uses about 1/3 of the electricity compared to a standard electric water heater, saving up to 70% energy.

What does the anti-legionella cycle do?

It heats the water to 65°C periodically to kill Legionella bacteria, ensuring safe drinking water.

Can I connect solar panels to this unit?

Yes, the VPD 150 supports solar preheating with an optional solar coil kit.

What is the warranty period?

Nibe offers a 2-year warranty on parts and labor, and up to 5 years on the tank if registered.

How to silence the unit if it’s too loud?

Check for vibration isolation and ensure the unit is on a solid floor. Clean the air filter to reduce fan noise. Sound level is typically 48 dB(A).

Maintenance

Safety valve (not supplied)

The safety valve must be inspected regularly, about 4 times a year, to prevent blockages. To inspect the valve, open the safety valve manually and check that water flows through the overflow pipe. If this does not happen, the safety valve is defective and must be replaced.

The safety valve sometimes releases a little water after hot water has been used. This discharge is caused by the expansion of cold water entering the water heater, resulting in a pressure increase, whereby the safety valve opens.

Emptying

1. Shut off the incoming cold water.
2. Open the drain connection, or the drain valve if fitted.
   During draining, air must be let into the water heater by loosening a hot water connector (XL4) or opening a hot water tap.

To ensure that the water heater drains completely, a hose, or a pipe, with an outlet below the lowest level of the water heater must be attached to the drain connection or drain valve. When installed in a location that is exposed to the risk of frost, the water heater must be emptied whenever it is not in operation. Freezing will result in the water heater bursting.

Service

For service, contact the installer. Serial number (PF3) (14 digits) and installation date should always be stated.

Only replacement parts supplied by NIBE may be used.

3 For the Installer

General

Supplied components

VPD is a water heater, which is suitable for connection to heat pumps.

The water tank has internal stainless steel corrosion protection.

The water heater is designed and manufactured for a maximum cut-off pressure of 10 bar. Maximum permitted temperature is 95 °C.

The insulation is polyurethane, which provides excellent heat insulation. The outer shell on VPD is grey plastic.

VPD is equipped with submerged tube for control of 1hot straight G15/22 connec-x straight G15/15 connec-water heating. tion

Transport

VPD should be transported and stored vertically in a place. The VPD may, however, be carefully laid on its back when being moved into a building.

Assembly

The water heater is only designed for upright installation _x 22/15 connections. The water heater's installation area should always have a temperature of at least 10 °C (frost-free).

Position VPD on a firm base that can take the weight, preferably on a concrete floor or foundation. Use the product's adjustable feet to obtain a horizontal and stable set-up.

The area where VPD is located must be equipped with floor drainage.

Pipe installation

The enclosed kit includes suitable connectors that can be used for the installation.

Pipe installation must be carried out in accordance with current norms and directives.

The water heater must be fitted with the necessary valves, such as a safety valve, shut-off valve and non-return valve.

The water heater must be provided with a mixer valve, which limits the temperature of outgoing hot water to 60 °C. If this valve is not fitted, some other measure must be taken to prevent the risk of scalding.

Internal support bushes must be fitted when a plastic or annealed copper pipe is used. An overflow pipe must be routed from the safety valve to a suitable drain. The overflow pipe must be the same size as the safety valve. Route the overflow pipe from the safety valve, sloping along its entire length and ensure that it is frost proof. The mouth of the overflow pipe must be visible and not placed close to electrical components.

Heat pump

Connecting to heat pump

The heat pump supply and return are connected to

L36 Supply line 0 Install the T-coupling in position (XL3) (blue) as illustrated.

- Connect the return line from the heat pump to the angled connection on the T-coupling. Install the supplied non-return valve on this pipe.

VPPdstall a shut-off valve on the incoming cold water pipe.

• The safety valve must have a maximum 10.0 bar opening pressure and be installed on the incoming cold water line. The entire length of the overflow water pipe from the safety valves must be inclined, to prevent water pockets and must also be frost-free.
  ■ Connect the incoming cold water to the T-coupling.
• Angled couplings, 22/15 mm, installed on connections (XL4) and (XL36) as illustrated.
  ■ Connect the supply line from the heat pump to pos (XL36) (white) on the water heater section.
  ■ Hot water connection to pos (XL4) (red) on the water heater.

Installation alternative

VPD can be connected in several different ways, one of which is shown here.

Further option information is available at www.nibe.eu and in the respective assembly instructions for the heat sources used.

To exhaust air heat pump

VPD can be docked with heat pump, for example NIBE exhaust air heat pump.

Filling

Fill the water heater as follows:

1. Open a hot water tap in the system.
2. Fill the hot water heater through the cold water connection (XL3).
3. The hot water tap can only be shut off when the water heater is filled, which is when only water comes out of the tap (initially an air-water mixture comes out of the tap).

Electrical installation

NOTE Electr

Electrical installation and service must be carried out under the supervision of a qualified electrician, and in accordance with applicable electrical safety regulations.

^1 VPD can be supplemented with up to two hot water sensors, one for display and one for control. The display sensor is positioned in the submerged tube for the display sensor (UA1) and the control sensor is positioned in the submerged tube for the control sensor UA2. In cases where it is only possible to connect one sensor, use the submerged tube for the control sensor (UA2).

Use the sensors provided with the heat pump (or other heat source). When no heat sensors have been provided these must be ordered from the manufacturer of the heat source.
