Baxi Appliance Repair in Langley Green & Tushmore

What does the error E154 mean on a Baxi boiler?

Error E154 on a Baxi boiler indicates a plausibility test failure between flow and return temperatures. This suggests a circulation fault. Switch off the boiler and check for airlocks or closed valves. Contact a heating engineer if the fault persists.

What does the error H.03.54 mean on a Baxi boiler?

Error H.03.54 on a Baxi boiler indicates temporary flame loss and shutdown due to the power supply voltage being too low. If you smell gas, do not operate any electrical switches, ventilate the area if safe to do so, leave the property, and call the gas emergency line from outside. Check if other electrical appliances are working. Contact a Gas Safe registered engineer if the error persists.

What does the error E.02.17 mean on a Baxi boiler?

Error E.02.17 on a Baxi boiler indicates permanent communication failure between the gas valve and boiler PCB. If you smell gas, do not operate any electrical switches, ventilate the area if safe to do so, leave the property, and call the gas emergency line from outside. Do not attempt to operate the boiler. The gas valve, wiring, or PCB may need replacement. Contact a Gas Safe registered engineer.

What does the error E20 mean on a Baxi boiler?

Error E20 on a Baxi boiler indicates a central heating temperature sensor fault. Contact a Gas Safe registered engineer to test and replace the faulty NTC sensor.

What does the error E384 or 164 mean on a Baxi boiler?

Error E384 or 164 on a Baxi boiler indicates false flame detection when there should be no flame. If you smell gas, do not operate any electrical switches, ventilate the area if safe to do so, leave the property, and call the gas emergency line from outside. This is a safety concern requiring professional inspection. Do not attempt to operate the boiler. Contact a Gas Safe registered engineer to check the ionisation electrode.

What are the different types of Baxi boilers?

Baxi offers three main types of boilers: combi boilers (which provide heating and hot water on demand without requiring a cylinder or tanks), system boilers (which include the expansion vessel and pump but require a hot water cylinder), and heat-only boilers (which require both a cylinder and cold water tanks in the loft).

When should I replace my Baxi boiler?

A Baxi boiler typically has an average lifespan of around 10 to 15 years, depending on how well it is maintained. Regular servicing helps the boiler reach the higher end of its lifespan.

How efficient are Baxi air source heat pumps?

Baxi air source heat pumps are generally 300 to 400% efficient. This is measured as Coefficient of Performance (COP), meaning the heat pump can create three to four units of energy for every one unit of electricity it uses.

What is a condensing boiler?

A condensing boiler is a high-efficiency boiler that captures and reuses heat from the flue gases that would otherwise be lost. All modern Baxi boilers are condensing boilers. The technology uses larger heat exchangers to recover almost all the heat, reducing fuel consumption and emissions.

Do I need a cylinder with a Baxi heat pump?

Yes, Baxi air source heat pumps require a hot water cylinder as they do not provide instant hot water like a combi boiler. The Baxi ASHP cylinders are designed specifically for use with heat pumps and feature larger coils for better heat transfer at lower flow temperatures.
