I am contemplating replacement of our boiler which is currently a Worcester 28cdi Combi.
The boiler itself works and I don't have any issues with its reliability other than I believe it is insufficient for the type of property and that when it was installed by the previous owner no though went into its installation.
The house is long and narrow, has 3 reception rooms and a kitchen with 5 bedrooms and 1 bathroom. It is also End Terrace and is exposed on 1 side in its entirety and the rear and also half way down the other side.
It is over 3 floors, although the upper floor is into the attic space (not a conversion).
All the walls have been insulated, the loft requires further insulation (which I will do once I install a loft hatch and get access to it).
I have looked through this forum and found quite useful information and a great deal of things to think about.
However my issue is where I start, currently the boiler doesn't seem (and this is my opinion) to heat the radiators fully and I believe this is because it is not adequate.
I was thinking of going back to a system boiler with a pressurised water cylinder. I have used an online calculator to work out what KW boiler I would need and it did give me a ridiculous figure of 72 - so I think I was entering something wrong.
I wondered how this is approachable. and what to look for in a replacement, also how much power would be required to make sure that the system heats up the house rather than keeping it warm as it currently does.
I am fond of the Atag A320s at the moment or the Viessmann Vitodens 200 35KW.
I am not sure if these are powerful enough and also if there is anything else that you would recommend.
