Remeha Appliance Repair in Southgate

What does the error E04.12 mean on a Remeha Quinta Ace boiler?

Error E04.12 on a Remeha Quinta Ace boiler indicates a false flame was detected before burner start. This is a potentially dangerous condition. Do not attempt any repairs. Contact a commercial heating engineer immediately to check the ionisation electrode and gas valve operation.

What does the error E[02 mean on a Remeha Quinta Pro boiler?

Error E[02 on a Remeha Quinta Pro boiler indicates the flow temperature sensor has a short circuit. Check sensor wiring and verify correct fitting. Contact a commercial heating engineer to test and replace the sensor if necessary.

What does the error E28 mean on a Remeha boiler?

Error E28 on a Remeha boiler indicates a flue thermistor fault. In cold weather, check for a frozen condensate pipe and thaw if necessary. If not frozen, contact a Gas Safe registered engineer to inspect the flue system and sensor.

What does the error E04.13 mean on a Remeha Quinta Ace boiler?

Error E04.13 on a Remeha Quinta Ace boiler indicates the fan speed has exceeded the normal operating range. Contact a commercial heating engineer to verify fan wiring and check for excessive chimney draught affecting the system.

What does the error E15 mean on a Remeha boiler?

Error E15 on a Remeha boiler indicates flame loss during operation. The flame was established but then lost. Contact a Gas Safe registered engineer to check ignition wiring, gas supply, and for recirculation of flue gases.

What is OpenTherm and why should I use a modulating thermostat with my Remeha boiler?

OpenTherm is a communication protocol that allows compatible thermostats to modulate the boiler output rather than simply switching it on and off. Using a modulating thermostat such as the Remeha iSense or qSense significantly improves efficiency compared to basic on/off control. The boiler adjusts its output to match the actual heat demand, reducing energy waste and providing more consistent comfort.

What is included in a Remeha boiler service?

A Remeha boiler service typically includes checking the flue pipes and air supply pipes for leaks, checking the condensate siphon, checking hydraulic pressure, measuring ionisation current, inspecting flue gas connections, and cleaning the heat exchanger and plate exchanger if required.

Why is my Remeha boiler not producing hot water?

If your Remeha boiler provides heating but not hot water, check the water pressure first and repressurise if below 1 bar. The diverter valve, which controls flow between heating and hot water, may be faulty. Alternatively, the heat exchanger may be scaled up, particularly in hard water areas.

What size Remeha Quinta Ace boiler do I need?

The Remeha Quinta Ace range is available in outputs from 30 kW to 160 kW. Correct sizing is essential to maximising performance and efficiency. An undersized boiler will struggle to meet demand, while an oversized boiler will short-cycle, reducing efficiency. A detailed heat loss calculation for your building is essential.

Can Remeha Quinta Ace boilers be cascaded?

Yes, the Remeha Quinta Ace is ideally suited for cascade systems. A maximum of four appliances can be cascaded directly from appliance to appliance using quick-connect plug-and-play connectors. The compact boiler dimensions enable rapid installation and flexible siting.
