Hi,
I really need a new gas boiler and I just need to check something I've been told.
One chap came round and quoted to replace the existing gravity system with another gravity system (hot water is on gravity, radiators are pumped). This is a conventional boiler.
Another chap came and said that it's against some regulations to fit gravity systems and also wanted to sell me a combi for various reasons. (easier to fit, more loft space, less corrosion due to sealed system and might save me a few quid in gas bills)
Is it true that gravity systems are not allowed?
Also, the 2nd chap said he has to fit a room thermostat even though he can't see the point in them as he fits those things on the radiators. Is that right? You have to have a room thermostat now? The first guy wasn't going to fit one.
Thanks.
Peter
