Hi
I would like to work out the cost savings if I swapped our old combi boiler for a new one.
The existing combi is a Glow-worm Swiftflow 80, Efficieny Band F (10-15 years old?).
I am looking at a Glow-Worm Betacom 28A HE Gas Combi (http://www.boilers2go.co.uk/Glow-Worm-Betacom-28A-HE-Gas-Combination-Boiler.html).
We only have a 2-bed mid terrace and I think this is powerful enough.
HW is currently coming out at 9 LPM in to a weir cup and that is fine for us.
Also Energy Saving trust website says 9KW is what we need for boiler output as its a very small house.
However I can't find any info on running cost savings, only that newer boilers are more efficient!
Thanks peeps.
