Baxi Appliance Repair in Broadfield

What does the error E.02.35 mean on a Baxi boiler?

Error E.02.35 on a Baxi boiler indicates a critical safety device has been disconnected. Do not attempt to operate the boiler. Contact a Gas Safe registered engineer immediately to inspect and repair the safety system.

What does the error E.04.17 mean on a Baxi boiler?

Error E.04.17 on a Baxi boiler indicates a fault in the gas valve control circuit. 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 reset or operate the boiler until professionally inspected. Contact a Gas Safe registered engineer immediately.

What does the error H.01.08 mean on a Baxi boiler?

Error H.01.08 on a Baxi boiler indicates the flow temperature is increasing too quickly in heating mode, causing a temporary stoppage of 10 minutes. This suggests a circulation problem. Check for closed valves or airlocks. The boiler should reset automatically. Contact a heating engineer if it recurs frequently.

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 does the error E104 mean on a Baxi boiler?

Error E104 on a Baxi boiler indicates a faulty Safety Assist PCB. This is a critical safety component. Do not attempt to operate the boiler. Contact a Gas Safe registered engineer for inspection and repair.

Can a Baxi heat pump work alongside a boiler?

Yes, a Baxi air source heat pump can work alongside a boiler in what is called a hybrid system. The boiler provides supplementary heating during extreme cold weather, temperature delays, legionella cycles, or if there are any issues with the heat pump.

Do I need to change my radiators for a Baxi heat pump?

Most radiators in homes today are sized for 80°C boiler flow temperatures. Since heat pumps operate at lower flow temperatures of around 50 to 55°C, radiators may need to be enlarged to deliver the same heat output.

How does a Baxi combi boiler work?

A Baxi combi boiler combines heating and hot water delivery in one compact unit. When the room temperature drops below the thermostat setting, the boiler heats the central heating system. When a hot water tap is turned on, a valve inside the boiler diverts heat to the domestic hot water supply until the tap is turned off.

What are the running costs of a Baxi air source heat pump?

When properly sized and installed, a Baxi air source heat pump typically costs the same as it currently does for gas and electric to heat a home, with the bill being entirely electric. In some circumstances the cost could even be reduced, depending on usage patterns.

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.
