Hi,
Sorry if this is a really dumb question. I'm used to seeing combi boilers now with the sealed CH circuit and a separate pipe for HW on demand.
In a house I'm renovating the coil in the HWC seems to be fed from the central heating circuit (gravity fed). I suppose my question is is this normal? I'd assumed the boiler had a separate loop for HWC so you're not limited to having HW only when the CH is on and relying on the immersion for the rest of the time (and potentially all through the summer).
