Hello and thanks for any help:
My elderly parents have signed up for a free central heating renewal with Scottish Gas. (worth £4k apparently so not to be sniffed at)
They just got a 'phone call to say the new heating will be fitted this Thursday (16th June) A guy called today to take measurements and told them they will be getting a 25kw combi boiler "because they are more efficient". No choice.
When my dad asked what would happen to their existing storage tank and gas fired AGA cooker/hot water boiler he was told, "no problem we'll just isolate them"
Here's what they have just now:
A large and rambling victorian stone villa over two floors with 4 bedrooms.
A wall mounted gas boiler heating 12 radiators but not hot water.
A gas fired AGA (circa 1989) which heats hot water into an insulated storage tank in the downstairs kitchen and does cooking duties.
My concerns about the combi boiler option are as follows;
Will it be able to supply the level of hot water they are used to?
(They have a non-thermostatic shower connected to the bath taps and a large bath which is about 14 metres distance from their boiler)
Is it really "efficient" to junk a perfectly good storage tank and associated piework in a system that currently suits them fine, albeit an ancient one?
They are at home all day, both retired, cooking, washing, bathing.
What will the AGA do with all its surplus heat output if it is simply disconnected? Does a high powered appliance like this not need a dedicated, permanent heat sink? At present their water is always scalding hot. Where is the unused heat going to go?
Should they re-think this before the fitters arrive in 48hours?
Any thoughts welcome. ASAP please because of shortage of time.
