Hi
Can anyone explain to me what might be happening with my heating system?
I have recently had a multi-fuel stove (Hercules 30B) installed, with a back boiler, in order to provde hot water and serve 12 radiators. This boiler is supposed to be able to deal with 20 radiators.
I also had all our old radiators replaced with new ones and TRVs. The old system was oil, inefficient and incredibly expensive. The point of the new system was to be able to control how much it cost and to have better radiators. All of the pipework is now as it should be with solid fuel.
This is what happens - if we have just the stove on, the flow and return pipes get so hot that you can't touch them. At this point we put on the central heating, and the return pipe immediately goes cold, whilst the flow pipe cools to a lesser degree. Also, as soon as the heating is switched on, the rads get hot, but after a few minutes, they all go lukewarm. I have set all the TRVs to the highest setting - there is no way they could be thinking it's hot, though, as the house is cold!
We have tried this with only one rad (+ heat sink rad, of course), and adding to it, and with all rads on. Also, as the central heating is taking the hot water, the stove itself becomes cooler. Thinking logically, we feed and feed the fire, but practically nothing happens (occasionally a slighter warmer radiator, but not hot).
One annoying thing is that, in order to get central heating, we have to get the 'clock' to ask for hot water as well, even though this is provided by the boiler separately. Could this be the problem, or are we doing something wrong? We will get the company out and they are very nice, but I just want to feel more informed when we do.
Thanks
