Hi there
I'm considering changing from a vented system to a combi pressuriesed system (4 bed, 3 bathrooms). The thing is - even the biggest combi's cannot cope with potential HW demand (heating not a problem). I was just wondering if anyone had considered installing two cheaper combi boilers in parallel, simply teeing the inlet and outlet pipes. Supply pressure (water and gas) as well as bore diameters would need careful consideration, but could be quite a good solution, including redundancy, so that if one packs up you still have heating and hot water until it gets fixed. Should be fairly straight forward.
Also, can you fit a single controller in parallel as well?
Neat idea, huh?
