My installer has quoted for a Keston 40 system boiler, but have read too many adverse comments on this site to accept that make.
My research seems to show that the choice is between the Weismann Vitodens 200W (or 100W?), the Intergas SB 30 (or OV30), or the ATAG A320S.
My current boiler has been in place for some many years, and judging by the colour (& viscosity!) of any water bled from the system, is in need of power-flushing.
Bearing this last factor, does the Intergas heat exchanger offer my best bet, or does the 4:1 modulation of the other burners trump that - providing I fit a spirovent magnabooster?
