Baxi back boiler heating/hot water problem

[peteeyres]

I've got an old heating system in my house, for us to have hot water I have to have the heating going, there are not individual controls. Doing this when the weather is nice makes the house roasting hot and all the windows being open (heating the street). This has also sent my bills stupidly high. I know the best option is to change the system and get a combi and new fire but financially I'm not able to at the moment. So my thinking was to put radiator thermostats on each radiator to hopefully have them on a minimum and it meaning I would still get hot water. Does this make sense or wouldn't it work and I would still roast in whatever room I was in.

Yes having TRV's would turn the rads off, however I'm not sure you would even have to do that, your sys doesn't sound right that your CH has to be on with HW, normally other way round, why don't you get someone in to have a look at your system, could possibly update it with zone valve in the right place may solve your troubles

I had one of these last week. I'm amazed there are still any left!

You'll need to get a plumber in to do what Savage suggested above - fit a zone valve and cylinder stat etc.
