The flow rate coming in is the deciding factor. 70kW should be enough, but the water pressure could be too low for all 4 showers at once, I hadn't thought of that one, cheers
Hi All,
I've got a customer who wants 4 showers in one house. They don't want electric showers, so I guess it'll have to be a big cylinder. But would it be possible to put 2 combi boilers in, so as not to have to store hot water? I assume the cylinder would need to be quite big for 4 showers...
