Hi Folks,
I'm now at the "tendering" stage of my boiler replacement and I'm
shopping around for a new 40Kw condensing boiler (not a combi boiler).

The current boiler of choice is a "Greenstar HE 40 open system boiler",
so a quick Google on some of these words has illustrated "Discounted
Heating"
at http://www.discountedheating.co.uk
Anyone got experience of these folk?

They have a couple of Greenstar boilers but the one I think I am
interested
in has the acronym "RSF" tacked on to the name and I don't recognise
what
this means (some sort of "flue" specification? Dunno).

I've also been told that I will need some sort of "programmer". Since I

already have a timeswitch (now only for the hot water) and I fitted a
programmable thermostat a couple of years ago I am questioning what
exactly
this programmer will do for me - is it essential, desirable or
redundant?

Any help appreciated; thanks in advance

Mungo
