we have an open fire in the living room with gravity fed (but also pump assisted) heating. and thats it! and we struggled to find a plumber that understood the system when we had problems with it, sorted it ourselves however, thankfully!
we have frequent power cuts too, but can keep the fire on, it never produces enough to cause a problem, we need the immerser on as well to produce water hot enough to wash up for instance.
i would agree with the woodburning/multifuel cooker/water/heating/ stove in the kitchen, plus an open fire or smalle enclosed fire in the living room, keeps you options more flexible. plus, if its a big kitchen you will likey spend more time in there?
