central heating system working top-grade domestic water not heating
Most conventional as said is diaphragm or diverter valve, also thermistors, thermostat (if dual charge), flow switch, fan not increasing speed, pcb, or a blockage, you desideratum a corgi engineer to look at it.
This quintessence of back boiler was very common before central heating. I want to know if there are any still at one's fingertips.
Try this tie-in.

Yearning it helps.
Needs changing as it tends to nail when changing over from heating to domestic water.
An electrically operated valve can be un-freed as follows...... Bump off actuator head by removing 2 screws exposing the tangible valve itself. With a pair of pliers turn the place many times, this will free-up the valve, replace nut.
NO NEED TO DRAIN
Make sure you have inhibitor in the system, this prevents ebon rust (magnetite) which clogs valves.
I have a 10 month old sealed central heating system, no development tank in attic. Boiler is heating water in the domestic ring false cylinder but is not getting the rads warm and in some cases they are stone stone-cold. Have tried to bleed the rads as I used to do in our old auditorium but there is no air in the rads. System worked up till April OK. Can judge water in the pipes is hot but is just not circulating. Any ideas or do I necessity to get a plumber?
Perchance there is a problem with the heating pump?
Basically, unless I am missing something, assuming you have a seperate issuing pump for the space heating, it is all I can think of. The problem apparently isn't the boiler or you would get no domestic hot water.
If your pump has exam points before and after it (openings in the pipework you can insert a look into into) you could hire a differential pressure gauge from Rental Shop (or other) and test the pressure across the pump. if it was low or nothing, you would certain the pump has failed somehow. Unless you know how to, you will destitution a plumber to replace it.
Our enterprise central heating comes on for 1 hour in the morning and 5 hours in the evening. when it is on it also heats the hot top in the cylinder. I've had different advise as to whether it is cheaper to renounce the gas on to heat the water 24/7 (independently to the domicile heating) so it always stays hot & needs little warming up, or to fervour the water only when the house heating is on (so the water temp will declivity in between and need more energy to heat). What do you all think/differentiate???
Thanks very much
John
all depends how much bath-water you use really if the hot tap is not always going with washing kids bath etc then lawful set hot water and heating together
