It needs to be a regular, vented system type boiler, but if possible
with separate boiler output temperature controls when heating the hot
water tank, to that when heating the radiators. Yes I presently have a
room stat and a water tank stat. I just like the hot water to be able to
be very hot 80C, I appreciate that is above the efficient condensing
range, but to heat the radiators the boiler output temperature need not
be quite so hot. 18+ Kw needed as present boiler is adequate. The
predecessor to that was around 32Kw, but some good insulation has made
that high an output unnecessary.

I had no input into the boiler make last time around, this time I am
looking to Vailant or Worcester/Bosch for a more reliable boiler.


Vaillant 400 series do vented and split temperature operation. They can
also do weather compensation if you want. Been very pleased with my 600
series system boiler so far...
