Hi Guys,
1st time poster,long time reader of AAM.Story is just finished new build and am having trouble with heating/hotwater/bolier. I have combination of underfloor heating & rads and hotwater tank all running from boiler. When I turn on all 3,the bolier kicks in and I can feel the flow in getting hot but it all goes to the underfloor heating and I get no hotwater in tank or radiators,this also happens on all combinations eg,water only,rads only. There is a switch which I presume kicks on a pump for the underflow, proveously if i didnt switch that on and got hotwater into tank and rads, now if I dont switch that on I get nothing and the bolier doesnt seem to kick in. Slighly confusing,any ideas would be appreciated.
Regards
