Thinking we need to switch from kerosene to gas. Current kero boiler is about 30 years old
As a complete novice what are the questions I need to be asking of any installers that I call.
I've read that we should allow approx 1.5Kw per radiator, we have 8 so = 12Kw?
If we ever extend should I over spec the boiler to allow for this and is there a disadvantage to this approach?
With the power shower I assume I need to keep the hot water tank and go for a system boiler?
Any recommendations as to makes?
Are we like the UK now in that it should be a condensing boiler?
Gas will be expensive if its not from the mains. You can over spec the boiler a bit anyway or it will be just running full blast the whole time and might not last as long
Yeah it will be mains gas.
Do I spec using the size of the rooms/radiators or just purely the number of rads?
House is approx 105 sq meters
