grundfos 15/60. I sometimes have a problem with s 53, it has reduced since reading this forum. I usually get it if heating has been on a while, then hot water kicks in. If I reset the boiler several times it is fine. I had reduced boiler output to 15. When I had the Vallaint engineer out he put a new coil in the boiler and advised moving pump closer to the boiler or putting another pump in. The boiler when I extended the house was resited 15m away from the valves and pump. I spoke to the fitter who installed my boiler and told both idea,s are a waste of time. Any help would be great
