Frequently Asked Questions - Egea Ht FERROLI

How do I adjust the water temperature on my Ferroli Egea HT?

Use the temperature control knob on the front panel. Turn clockwise to increase temperature (max 60°C) and counterclockwise to decrease (min 35°C). Wait a few seconds for the change to take effect.

Why does my water heater not ignite?

Check the gas supply valve is open, the mains power is on (or batteries are inserted), and the water pressure is above 0.2 bar. If the problem persists, refer to the fault codes section in the manual.

What type of gas can I use with the Egea HT?

The Egea HT is factory set for natural gas (G20). For LPG (G30/G31), a conversion kit is required and must be installed by a qualified technician. Check the gas type label inside the appliance.

How often should I service the water heater?

We recommend an annual service by a certified professional to ensure safe and efficient operation. This includes cleaning the burner, checking the flue, and verifying safety devices.

What does the red LED flashing mean?

A flashing red LED indicates a fault condition. Refer to the troubleshooting table in the manual for specific fault codes. Common causes include ignition failure, overheating, or lack of water flow.

Can I install the water heater outdoors?

The Egea HT is designed for indoor installation only. It must be installed in a well-ventilated area, away from direct moisture, and in compliance with local building codes.

What should I do if the water heater leaks?

Turn off the gas and water supply immediately. Do not use the appliance. Contact a Ferroli service agent for inspection. Leaks may be from loose connections or a damaged internal component.

Is the Egea HT compatible with solar water preheating?

Yes, the Egea HT can be used with a solar preheating system as it operates on instantaneous demand. Ensure the incoming water temperature does not exceed 60°C to avoid risk of scalding or damage.

How do I drain the water heater for winterization?

Turn off gas and water supply. Open a hot water tap. Remove the drain plug at the bottom of the unit (if equipped) to let water out. Reinstall plug before reuse. For frost protection, the unit has an anti-freeze function that activates when power is on.

5.1 Preparation of place of installation

The product must be installed in a suitable place, i.e. to allow normal use and adjustment operations as well as routine and extraordinary maintenance.

The necessary operating space must therefore be prepared by referring to the dimensions given in fig. 9.

fig. 8 - Minimum spaces

fig. 9 - Minimum spaces

The room must also be:

• Equipped with adequate water and electricity supply lines;
- Prearranged for the condensation water discharge connection;
- Prearranged with adequate water drains in case of boiler damage or safety valve intervention or the breakage of pipes/connections;
- Equipped with possible containment systems in case of serious water leakage;
- Sufficiently illuminated (where required);
• Not less than 20 m3 in volume;
- Protected against frost and be dry.

ATTENTION! To avoid the propagation of mechanical vibrations, do not install the equipment on floors with wooden beams (e.g. in the attic).

5.2 Securing to the floor

Pure diagram of a curved pipe or channel with directional arrows indicating flow or movement (no text or symbols)

fig. 11 - Securing to the floor

5.3 Aeraulic connections

In addition to the spaces indicated in 5.1, the heat pump requires adequate air ventilation.

Create a dedicated air channel as indicated in fig. 12.

fig. 12 - Example of air outlet connection
Install each air channel, making sure:

• It does not weigh down on the equipment.
• It allows maintenance operations.
• It is adequately protected to prevent the accidental intrusion of materials inside the equipment.
• The connection to the outside must be done with suitable, non-flammable piping.
• The total equivalent length of the extraction pipes plus the delivery, including grilles, must not exceed 12 m.
  The table gives the characteristic data of commercial ducting components with reference to nominal air flows and diameters 160 mm.

Data	Smooth straight pipe	Smooth 90° curve	Grille UM
Type
Effective length	1 \ m
Equivalent length	122m

During operation, the heat pump tends to lower the room temperature if the air ducting is not to the outside.

A suitable protection grille must be installed at the air extraction pipe to the outside to prevent any foreign bodies from entering inside the equipment. To ensure maximum product performance, the grille must be selected from those with low pressure loss.

To avoid the formation of condensation water: insulate the air extraction pipes and the ducted air cover connections with a steam-tight thermal covering of adequate thickness.

Install silencers if deemed necessary to prevent noise due to the flow. Equip the pipes, wall outlets and connections to the heat pump with vibration-damping systems.

ATTENTION!: The simultaneous operation of an open-chamber hearth (e.g. open fireplace) and the heat pump causes a dangerous negative pressure in the room. The negative pressure can cause the return of exhaust gases into the room.

Do not operate the heat pump together with an open-chamber hearth.

Only use sealed-chamber hearths (approved) with separate combustion air supply.

Keep tight and sealed the doors of boiler rooms that do not have the inflow of combustion air in common with living areas.

5.3.1 Special installation

One of the peculiarities of the heat pump heating systems is that these units considerably lower the air temperature, generally expelled to the outside of the house. As well as being colder than the ambient air, the expelled air is also completely dehumidified, therefore the air flow can be returned inside for the summer cooling of specific rooms or areas.

Installation provides for splitting of the extraction pipe, which is fitted with two dampers ("A" and "B") for directing the air flow to the outside (fig. 14) or the inside of the house (fig. 13).

fig. 13 - Example of installation in the summer period

fig. 14 - Example of installation in the winter period

5.4 Securing and connections of EGEA

The product must be installed on a stable, flat floor that is not subject to vibrations.

5.5 Plumbing connections

Connect the cold water supply line and the outlet line to the appropriate connection points (fig. 15).

The table below gives the characteristics of the connection points.

MANDATORY!: The system installer is required install a 7 bar safety valve on the cold water inlet.

NB!: The overpressure device must be operated regularly to remove scale deposits and to check that it is not blocked.

NB!: For correct installation of the unit, a hydraulic safety unit in conformity with UNI EN 1487: 2002 must be provided at the feed inlet and include at least: a shut-off valve; a check valve; a check valve control device; a safety valve; a hydraulic load cut-off device.

NB!: The discharge pipe connected to the overpressure device must be installed in a continuous downward slope and in a place protected against the formation of ice.

Water may drip from the discharge pipe of the overpressure device and this pipe must be left open to the atmosphere.

ATTENTION!: The heat pump for DHW production can heat the water to over 60°C. Therefore, to protect from burns, an automatic thermostatic mixing device must be installed on the hot water piping (fig. 16).

5.5.1 Condensate drain connection

The condensate forming during heat pump operation flows through a special drain pipe (1/2"G) that passes inside the insulating casing and comes out the side of the equipment. It must be connected, via a trap, to a duct so that the condensate can flow regularly (fig. 17).

fig. 17 - Examples of condensate drain connection via a trap

5.6 Electrical connections

The product comes already wired for the mains supply. It is powered via a flexible cable and a combination plug/socket (fig. 18 and fig. 19). For connection to the mains, a Schuko socket with ground and separate protection is required.

ATTENTION!: The power supply line to which the equipment will be connected must be protected by a suitable differential switch.

The type of differential must be chosen according to the type of electrical devices used by the overall plant.

For the mains connection and the safety devices (e.g. differential switch), comply with IEC standard 60364-4-41.

5.6.1 Remote connections

The equipment is prearranged to be connected to other remote energy systems or energy meters (solar thermal, photovoltaic, Off-Peak)

INPUTS

• Digital 1 (DIG1). NOT USABLE

(THE TWO WIRES, WHITE AND BROWN, OF THE 6-CORE CABLE ARE NOT TO BE USED)

- Digital 2 (DIG2). Digital input for photovoltaic. In case of a photovoltaic system connected to the plant, it can be used to subtract energy in the form of hot water in times of overproduction. If there is a voltage-free contact, e.g. from the inverter, which closes when there is overproduction of energy, it can be connected to the two green and yellow wires of the 6-core cable supplied with the equipment.

Set the parameter P23 = 1 to activate the supplement with photovoltaic.

- Digital 3 (DIG3). Input for Off-Peak. This function, available only in some countries, allows the equipment to be activated only when there is a signal coming from outside with prefer-

ential tariff. If the electric contactor has a voltage-free contact which closes when the preferential tariff is available, it can be connected to the two gray and pink wires of the 6-core cable supplied with the equipment.

Set the parameter P24 = 1 to activate Off-peak in ECO mode or P24 = 2 for Off-peak in AUTO mode.

If the equipment is not working properly, without any alarm signaling, before contacting the manufacturer's technical assistance service, it is advisable to carry out the following.

Fault Recommended action
The equipment does not switch on	Check that the product is actually powered by the mains.Disconnect the equipment then reconnect it after a few minutes.Check the power cable inside the product (Only for the installer).Check that the fuse on the power board is intact. If not, replace it with an IEC-60127-2/II certified time-delay 5 A fuse (Only for the installer).
Water cannot be heated via the heat pump in ECO or AUTOMATIC mode	Switch the equipment off, then switch it on again after a few hours.Disconnect the equipment from the mains, drain part of the water contained in the tank (approx. 50%) then refill it and switch the equipment on again in ECO mode (Only for the installer).
The heat pump remains on without ever stopping	Without drawing hot water from the product, check that in a few hours heating via heat pump occurs positively.
Water cannot be heated via the integrated heating element in AUTOMATIC mode	Switch off the equipment and check the safety thermostat of the heating element inside the equipment and reset it if necessary. Then switch on the equipment in AUTOMATIC mode (Only for the installer).Disconnect the equipment from the mains, drain part of the water contained in the tank (approx. 50%) then refill it and switch the equipment back on again in AUTOMATIC mode (Only for the installer).Access the installer menu and increase the value of parameter P32, e.g. to 7°C (Only for the installer).Check that the heating element safety thermostat has not intervened (see 8.2)
The product cannot be controlled via APP	Check that there is Wi-Fi network coverage, e.g. via smartphone where the product is installed, then carry out the configuration procedure again with the router. Make sure the Wi-Fi symbol on the display is lit up steady.

8.1 Power board fuse replacement

Proceed as indicated below (reserved for qualified technical personnel only):

• Disconnect the power to the equipment.
• Remove the top cover of the equipment and then the power board cover.
• Remove the fuse cap, then the fuse, using a suitable screw-driver.

8.2 Heating element safety thermostat reset

This equipment has a manual-reset safety thermostat connected in series with the heating element immersed in water, which interrupts the power supply in case of overtemperature inside the tank.

If necessary, proceed as follows to reset the thermostat (reserved for qualified technical personnel):

• Unplug the product.
• Remove any air ducts.
• Remove the top cover by first undoing the locking screws (fig. 41).
• Remove the front panel and manually reset the tripped safety thermostat (fig. 42). In case of intervention, the central pin of

fig. 42 - Front panel removal

ATTENTION!: Intervention of the safety thermostat can be caused by a fault linked to the control board or by no water inside the tank.

ATTENTION!: Carrying out repair work on parts with safety function compromises safe operation of the equipment. Replace faulty parts with original spare parts only.

NB!: Intervention of the thermostat excludes operation of the heating element but not the heat pump system within the permitted operating limits.

ATTENTION! If the operator is unable to eliminate the fault, switch off the equipment and contact the Technical Assistance Service, communicating the model of the product purchased.

9. MAINTENANCE

ATTENTION!: Any repairs to the equipment must be carried out by qualified personnel. Improper repairs can put the user in serious danger. If your equipment needs any repair, contact the service center.

ATTENTION!: Before undertaking any maintenance operation make sure the equipment is not and cannot accidentally be electrically powered. Therefore, disconnect the power at every maintenance or cleaning operation.

9.1 Sacrificial anode check/replacement

The magnesium (Mg) anode, also called "sacrificial" anode, prevents any eddy currents generated inside the boiler from triggering surface corrosion processes.

In fact, magnesium is a weakly charged metal compared to the material of which the inside of the boiler is coated, therefore it attracts first the negative charges that form with the heating of water, consuming itself. The anode therefore "sacrifices" itself by corroding itself instead of the tank. The boiler has two anodes, one fitted in the lower part of the tank and one fitted in the upper part of the tank (area more subject to corrosion).

The integrity of the Mg anodes must be checked at least every two years (preferably once a year). The operation must be performed by qualified personnel.

Before doing the check:

• Close the cold water inlet.
• Proceed with emptying the boiler (see par. "9.2 Boiler emptying").
• Unscrew the upper anode and check its corrosion; if the corrosion affects more than 2/3 of the anode surface proceed with replacement.

Line drawing of a cylindrical industrial device with two vented chambers and a handle (no text or symbols)

fig. 43

The anodes have a special sealing gasket, to prevent water leaks; it is advisable to use anaerobic thread sealant compatible for use in heating-plumbing systems. The gaskets must be replaced with new ones in case of checking and also anode replacement.

9.2 Boiler emptying

If not in use, especially in case of low temperatures, it is advisable to drain the water inside the boiler. For the equipment in question, just open the drain cock as per the example hydraulic connections chap. "Plumbing connections" on page 78 (see fig. 16).

NB!: In case of low temperatures, remember to empty the system to avoid freezing.
