Hi, looking for bit of advice from a plumber type of chap. Im running a woodburning stove that heats hot water and rads, great in winter but i dont want the central heating pump to start at its preset 60 deg so can i set the pipe stat a bit higher in summer so that the tank water gets a bit hotter but the central heating pump wont kick in say set the stat to 70 deg, then at least it will kick in should things get a bit too hot, any problems with this? appreciate the help thanks
