Anyone have any suggestions for a new heating system?... Large detached property. Very open plan, 29 radiators, 4 bathrooms. Good mains pressure and flow rate..... Looking for a setup that someone has used before and works well. Cheers in advance
ive got 32 rads fitted two combis works fine 4 bath rooms with showers two sinks kitchen utility and wc
I run about the same number of radiators and 6 bathrooms off a grant 36 oil boiler and it’s fine. It copes well , largely because the house is well insulated. So depending on your insulation levels you may be able to run on a single large combi. It also helps me that. Out bathrooms are never all in use at same time.
used two as have two systems one up one down with manual connection valves as if one fails have a standby until fit new very handy but yes insulation is the key i concur
You could consider a large unvented cylinder and a heat only boiler (oil or gas) Also possible to have an unvented cylinder together with a combi boiler and use the combi boiler for only some hot outlets. I don’t advise combi oil boilers. Too complicated and troublesome
Unvented cylinder. Heat only boiler. Zoned heating. Maybe underfloor heating. Depending on how quick you want HW at outlets then maybe a secondary return.
Gas must pay well. or very small house with very small rooms. That sort of solution may get around multiple bath filling etc with just one combi. This place used to be fitted with 2 undersink gas water heaters piped to bathrooms. They may be an option to more than one combi. If I remember correctly each one was about 10kw but may have been less. I wonder about the Swedish option. Electric panel heaters and underfloor. Hard to compare running costs especially as we have been using a lot of gas to generate electricity but in terms of efficiency that type of heating is 100% efficient. It also has quick heat up times.
