Yes makes sense.
We needed to upgrade the control manifold for the floor heating as The old (plastic) unions were leaking too much to use it the first winter we were here (moved in mid winter and the Stove had not been used at all for 8 years) So the 300 litre hw tank often boiled....especially as the thermostat to run a pump to cycle the water through the stove had also failed. Can heat a lot of water these things, especially with good wood. Boiling is no problem,apparently, other than the noise it makes.....time to let the fire slow down or have a very deep bath to cool the water or both....
