Central heating tips and advice from a full-time UK central heating engineer. How-to guides from an everyday plumber.
Baxi boiler pressure should be between 1 – 1.5 bar on the pressure gauge when the heating is off and the radiators are cold. I have been repairing boilers and central heating systems for over a decade and have come across every pressure problem. Here I’ll give you my best advice for pressure problems on […]

A boiler filling loop is needed on all pressurised central heating systems. If you have a combi boiler or system boiler you should have a filling loop. The filling loop is used to repressurise the boiler by connecting the cold water to the heating system via a flexible or solid pipe and two valves. I

A pressure relief valve (PRV) is a safety valve on a central heating system to prevent the pressure from getting too high and becoming dangerous. When the boiler pressure is too high and reaches 3 bar, the PRV will release the water from the system and discharge it outside. I have been repairing boilers full-time

Ideal boiler condensate traps can get very dirty and eventually blocked if they are not cleaned out. They get full of all sorts of weird gunk and sometimes bees and other insects that get in through the flue terminal from outside. I have been servicing boilers for a decade and I have cleaned my fair

Condensing boilers produce wastewater (from the flue gases) that needs to run freely down through the boiler, into a trap, then down a pipe and discharged into a drain. Having a blocked condensate pipe means your boiler will not work. These pipes become blocked regularly. I have been repairing and servicing boilers for over a

Sick of your boiler losing pressure and having to keep repressurising it? well, recharging the expansion vessel might just be the job needed to get it properly fixed. Recharging expansion vessels is hard to do when you do it for the first time. I have been repairing and servicing boilers for over a decade and

Having high boiler pressure is a problem. There are a few different causes and a few different fixes. When the pressure keeps rising too high it is usually followed by it dropping too low after the pressure relief valve lets the water out of the heating system. I have been repairing boilers and heating systems

A Magnaclean is a central heating magnetic filter made by Adey which collects iron oxide and sludge that builds up in central heating systems. This stops the sludge from collecting in parts on your boiler which causes boilers to break down. This filter can be isolated from the heating system, and then removed and cleaned.
