can someone decipher this gravity fed system

wrightk

I have a 10kw stove powering 6 radiators and obviously the hot water. the stoves in the kitchen, and theres two rads downstairs, one in rooms either side of the stove and with the hot water cylinder and pump,stats etc just off the kitchen in a cupboard.


Before the pump kicks in there is a lot of heat in the bathroom radiator, i was under the impression that this one is heated by gravity and usually doesnt have controls on it to adjust temps etc but this one does and is always warm even when the heating has yet to kick in.

The bathroom and bedroom upstairs (which are adjacent and i presume connected directly to each other) rads power up fine.
The problem i have is with the other rads, which are also on adjacent walls. When we moved in they seemed to be warm but now are stone cold, i have bled, opened up valves, checked the trv's on both and everything seems normal. i have even had a heating engineer round who is also stumped.

The only time one of these faulty rads seem to get at least tepid is when the stove has been on constantly for about 2 days.

The house is lovely and warm on the rads that work just not on these two rads, im quite a technical person and hate not knowing whats going on, particuarly as this is our first solid fuel system and i dont really understand the flow of the rads in the house.

hope someone can help, thanks

Have you tried turning off each of the radiators that work to see if the ones that don't then get hot?

I ask because the only way I can get the second radiator in our living room to work is to turn off a working radiator in a bedroom. I discovered this by trial and error. Luckily, we don't use that bedroom.
