It might have been a plumbing issue tbh the more I think about it.
The range in the kitchen had an internal boiler and the hot water cylinder for the house was situated directly behind it (hotpress backed on to kitchen). Pipes went from range to tank.
As for the living room stove, its a Waterford but since I am not the original owner of the house, I do not know either the model number or the output of it. But it is a fairly big lump of a thing, maybe the older version of something like this:

Now it might be the smaller or less efficient, not 100% sure. It seems to heat up most of the radiators in the house, but not all of them to the same level, so I'm guessing its not powerful enough to heat the entire house.
So can some stoves only heat rads without heating hot water? Sorry if this sounds like a dumb question but I thought that if they were making hot water for rads then they would also provide hot water for baths/showers at same time.
