i need to know boiler specifics- make and model but sounds like either the air pressure switch seized or the main printed circuit board, if the boiler has an overheat thermostat please ensure that the little red button hasnt popped out because this will prvent the boiler firing up- refer to the manufacturers instructions for location of the o/heat stat

SOURCE: Combi Boiler pressure gauge reading 0, and radiator half on!

The first thing you need to do is to put some more water into your heating system. This is usually done by allowing water from your (pressurised) domestic cold water supply to flow into the system: On older boilers, this is done with a connection (often made with a removable hose) on the pipework just outside the boiler. Newer boilers may have a built-in connection with some sort of removable link (sometimes looks like a plastic key).

Once you've got the boiler up to working pressure (typically about 1 bar - 15 psi), you should be able to bleed your upstairs radiator properly.

This may be all it takes, though the pressure excursions you're getting when you run the hot tap suggest there may be another problem. See what happens to the pressure as the boiler heats up and cools down. There really ought to be very little pressure difference between the two conditions. If you see significant changes, this usually means that the "pressure vessel" (or in hydraulic terms, system accumulaor) has lost its air charge.

The pressure vessel is a metal container inside the boiler, usually painted in red enamel. Somewhere near the top, you will find a schrader valve (like the one on a car tyre), and you can use this along with a tyre pump to replenish the air in the top of the vessel. This will reduce your pressure transients for a while, but you need to keep an eye on it. If the problem returns, you probably need to replace the pressure vessel (or clag another one into the plumbing alongside the boiler).

Baxi duo-tec boiler - when water comes on flame roars up. When i put the heating on the flames roar for 5 minutes then die down.


is the boiler a combi if so have you checked the pressure. it needs to be at 1.5 bar 2 bar at the most . also check that the heat the boiler is producing is completeing the circuit on the heating if you have access to the pipe work there should be 2 or 3 22mm copper pipes. now turn the heating on and check which one is getting warm. the one that is is your flow and in about 2 to 3 min there should be one more pipe getting hot let me no if this is the case

Our Baxi combi 130 HE heats the water OK but will not heat radiators. This has happened after a period of not using the radiators (ie. over the summer)


check the pressure it should be in  the green band, check the pump, inside the boiler cabinet lower right.
