Do I keep 2 boilers ??

edsredshed

I'm about to start converting a lower ground floor flat and upper maisonette into a family house and am trying to work out whether to keep both (reasonably new) combi boilers or remove them and replace with a condensing bolier.

If I kept them the basement one would power underfloor heating, a downstairs bathroom and any hot water needed in the kitchen, the upstairs one would power radiators upstairs plus the main family bathroom.

There's obviously a cost implication to changing them and buying a new condensing boiler but if its the right thing to do then I'd prefer to make the change now (while I'm ripping the house apart) rather than in a couple of years time. However on the flip side if there are benefits/efficiencies to be made by having two then I'd obviously like to save the ££ !!

Would really welcome any thoughts...

Thanks

Why could you not just keep one of the existing and let it run all of the system combined?

What combi's are they and how powerful?

I love resilient configurations, i.e. backup.
Two combis, two bathrooms, sounds good to me.
Having a separate heating system also means that you can heat just one floor: e.g. heat living space during the day, bedrooms at night.

I would put in some pipes (gas, CH, hot and cold) and conduits (cables signal and mains, separate for interference) for linking the two floors during the work, but not connected, in case you change your mind.
Think hub for each floor, and joining the two hubs.
