A bit of advice if any plumbers out there.
I have a solid fuel stove with a wrap around boiler. The boiler uses 1" copper and has 2 in's and two out's. The first circuit goes to the hot water tank and the second to the rads. There is a pump on the in from the rads and a stat on the out to the hot water tank.
Basically this means that the hot water tank is heated by convection and the rads are run by pump.
Would the stat be better on the out to the rads, as this cools down much more quickly than the out to the tank.
