SOURCE: boiler keeps losing pressure when the heatings off

Hi Leehardcast,

Yes the problems are related. The system is low on water. So now instead of water you have air in radiators which is easily compressed when it heats up. Then pressure loss when it cools down.

Add some water to your system until you have 15lb pressure and bleed out upstairs radiators at the same time.

Please rate this response and Good luck, Phil

Why does it take two bowls of water before water gets hot on combi boiler


The water isn't maintained hot (unless the central heating is on) in a combi boiler. you will, therefore have to turn the water on, which activates the burner. The burner will then have to heat up the heat-exchanger which then supplies the hot water through cold pipes. Once the pipes are warm, you will receive hot water.

I have a Potterton Combi Puma 80e When I use the shower the pressure seems to drop and shower goes cold! except when the central heating is on shower works fine


Does the red status led in the centre of the control board come on when hot water is drawn? You need to remove ONLY the front decorative cover to see the control board, two fixing screws at the base of it. If not the boiler won't fire when the CH is off.
The trigger for this is a pressure switch, replacement of which is beyond DIY scope.

Re: combi boiler.


if you have hot water at the taps but the heating isn't working make sure the thermostat is set high enough for the boiler to run check the time clock settings are on.
if these are working it could be a faulty diverter valve switch not sending a signal to the boiler to run.
