Ideal boiler no heat to radiators but hot water still working

    Check the circulator pump that moves the water through the radiators. It has probably gone bad. The boiler is working and heating so the hot water coils in the boiler are still making hot water for you. If you have a zone valve system then it could be a bad zone valve also. Make sure the thermostat is working and calling for heat and that the relay is that interfaces the thermostat and the circulator is working. As you can see there are a number of possiblities of where the problem could be. You will have to eliminate each one till you find the problem.

Check the divertor head and valve.
sounds like it ist adjusing from dhw to ch.
take head off(remove pi at back,or side pin) and push pin in valve when calling for ch,if it works then the head has gone.

Does the boiler thermostat control the heat of the radiators as well as the hot water temperature? Does the thermostat control the water temperature and the pump - as our pump seems to be on all the...


There should be a control called an aquastat that regulates the temperature of the boiler. The thermostat will turn on the circulator to start the flow of water through the radiators. If the water coming back from the radiators is very cold, a control will shut off the circulator until the boiler can come up to a predetermined temperature then start the flow of water again. If you have a tankless coil for domestic hot water, you now have a triple aquastat that maintains the temperature for domestic as well as the boiler temp. So yes the boiler thermostat (aquastat) does control the heat of the radiators and domestic hot water. No the pump is regulated by your house thermostat. You should take an amp draw on the boiler and componants to find out what is drawing more electricity than it should and popping your fuse.

I have the same boiler with a similar issue. The water is more than likley leaving the system from the pressure relief valve, which will be routed outside. It sounds like you have lost the pressure in your expansion tank, which is inside the boiler. With the boiler pressure at zero and the power isolated, the expansion tank can be accessed from a panel at the top of the boiler on the right hand side. You will see a valve on the red expansion vessel like the one on a car tyre and can be pressurised with a car tyre air pump. I think from the manual the pressure should be about 1 bar, but it depends on the length of pipework on your system. A competent boiler engineer should be able to sort this out, but it may be that your valve is leaking, or the expansion vessel has failed and the problem will occur again.
