Sep 25, 2013 · Although electric boilers are efficient by nature, because of the large size, it used more energy than a smaller boiler to get up to operating temps (we used it on demand) but once running, efficiencies were great. I suspect it would have worked better if we had used it often enough to justify continuous operation.Get Price
Nov 27, 2021 · It kind of depends how large the rads are but if they all average out @ say around 600x1000 K2's (Type 22) then there's loads of headroom in that boiler to cope with that demand. It will cope with a normal mains fed bar shower too @ 10L/min, that's also dependent on the cold mains pressure and flow or course.Get Price
