I am building a new extension and so my old Ideal Classic LXFF boiler, about 8 years old, has to go. (Although building inspector said I could make a case for keeping it, so there is obviously some discretion at least in Wandsworth BC).
I reckon I might as well get rid of it now and get a condensing boiler, as financially it is even weighted: the energy savings v keeping an old boiler going. I want to keep going with an open vent sealed system as I cannot use the roof space where the cold water tank is and I want a hot water cylinder as an airing cupboard, among other useful reasons.)
The house is 4 beds, one bath and one shower.
I am ready to go for a Vaillant Ecotec Plus 428 (£852 inc VAT), plus a Valiant Instor 155 litre hot water cylinder (£572 inc VAT).
I reckon this is a good, conservative choice, with everything Valiant. The hot water cylinder seems to have an expansion vessel. Would this be duplicating the expansion vessel I have in the loft?
In which case, am I wasting money?
