Hi, I have a trusty baxi solo 3 30 PF system boiler nearing 25 years old, still going, but probably not for long
Its rated output is 5.86 - 8.79 kw, which is *more* than enough for my *small* well insulated house (output is always set below medium on boiler). It heats my open vented Y plan system (4 rads/water tank/power shower pulling water from my hot water tank)
My GAS bills are VERY low in winter with heating on most of the day
The lowest output entry level open vented system boiler I could find is this one, but still rated at 18KW output...

I downloaded the installation manual and although above my head seemed to indicate that a competant installer can tweak the output too demand
So was wondering if an installer can limit the output to say 8KW, so it never goes above it?
PS Was also interested in any "alternative" ideas for heating instead of gas, for example was thinking along the lines of not having a boiler, just use the heating element in the hot water tank to heat my house on demand (opening the 3 way valve as needed with my thermostat switching the hot water element on/off). The additional electricity cost over gas would easily be covered by the £1000 needed to change the boiler!
