We found that our kitchen didn't get very warm last winter. So we've had a quote for a wood burner to be installed, which is much, much higher than I imagined - second mortgage-size.
So then I decided to take the economy approach and see if our CH system is capable of any improvement without going silly. I found some web-based tables that tell you how many BTU's (approx) a specific room needs - filled in a few, and they all came out roughly in the same place.
So - how do I tell (roughly) how many BTU's my existing radiators pump out? If they're insufficient I can put bigger ones in, if not we'll just have a cold kitchen.
Sorry this is such a dull question. But it's bugging me.
