    SE15 - Heating works on when the Hot Water is on

    I have an SE15 Boiler, and a Alpha 2 Pump connected to the tank. last week, I knocked the cable on the Alpha 2 pump, it knocked the power off, and I had to rewire the power socket to the pump. Now I can't get the heating on, unless the hot water is working. (I don't think the heating gets up...

    Adding tee on feed pipe to drain system

    Hi, I have a two-pipe fully pumped S plan open vented system. When I drained it last time, I had the impression there is some sludge or dirt around it. I therefore am going to drain it again to install a magnetic filter. I was thinking of taking this chance to add a tee on the feed pipe (the...

The house has a modern (2009) large extension, feels well insulated but with lots of glass and rooflights. The extension has underfloor heating, everywhere else...

We have now changed the fan, only to find after the boiler kicked in for a few minutes the fan started to make the same clunking screeching noises! Anyone have...

    Replace Danfoss RX1 with Hive Heating and Hot Water V2

    Hi all. Firstly...I realise that I should really use the Hive Heating only, but as I got the Hive Heating and Hot water for £95, and having read other posts on here, I believe that if your boiler uses 230-240V then it will work. Boiler : Gloworm 38CXi combi...
