Two combi and accumulator house advice needed

[Poppyplumbing]

I have been trying to get help to replace an old heating system"
Mix of electric & oil which leaves us freezing with small tank of hot water every day


British gas came round and couldn't quote or help


Local plumber no help couldn't quote




So looks like a diy job


We have 8 bedrooms


3 baths
2 kitchens
2 showers
2 cloakrooms


No insulation
Single glazed windows
380 m2


Would like 2 combi gas boilers. An maybe accumulator to feed them
As only get 14 to18 liters a min at tap


Not interested in unvented tanks !


Any advice on what combis and accumulator to give us a reasonable system would be greatly appreciated !

This is NOT a diy job!

A combi, or even two will not do what you want it to do. An accumulator will not help.

You need a sensible, experienced gsr with g3 to look at it.

You will need to readjust your expectations and reconsider an unvented cylinder.

Post a thread here, one of us might be able to quote for you.

Welcome to the forums Poppy.
Years of experience here for you however some can be slow to welcome you when you mention gas and diy, get it wrong and you may not live to regret it.

Interested in why BG wouldn`t quote.

Light commercial size of system you need, BG salesmen won't entertain as they are clueless, find another heating engineer, can always pay a consultant for design.

Not DIY job

Your gas meter is more than likely undersized to handle two combi boilers, especially if you have other gas appliances

Gas man said can do up to 63 kw

Why won't an accumulator help?
Can it not store water up to run 2 boilers at once when water is called for at say 14/16 l per min for each boiler ?
Or is a water tank / break an a pump work better?

as above defo not diy and the only way i could see it working is a viessmann 222 and a accumulator to hold it own for when more than one tap is opened, also it depends heat load for boiler sizing

where are you located poppy?
