Hi, I have an old heating system that consists of an Ideal Mexico Super 480FF boiler which has gravity hot water to a regular insulated copper cylinder. 11 radiators with one grundfoss pump. Honeywell Evohome TRV's on all radiators and a control valve connected to the return line of the hot...

Hi all, I've fitted a Salamader RP120SU hot water booster. And its sucking air/water from the vent pipe. Any suggestions how I can fix this? I've extended the vent pipe into the header tank so that it ends about 2/3 down into the tank water, this is just to allow me to run the pump without...

My bedroom stud wall is built onto the overhang of the floorboards after the joist below. So my joist runs parallel to the stud wall, but the stud wall is built about 100mm after the joist toward the stone outside wall so that the stud wall is just sitting on the ends of the floorboard which...

Hi all, I want to do away with our wood burning stove and close off the fireplace. Our house is heated by gas central heating and we never bother to put the wood burner on despite having crates and crates of wood. We want to close off the fireplace so that the opening is closed and plastered...

Hi, I have a low cold water mains pressure coming into our house. Our outside piping connects to the water main about 400 yards down the road near a school (we live rural) and I think that is our main problem. We do get 1 bar static pressure so the water authority will do nothing about...

Hi, I live in Scotland,UK and have a flat roofed house and my hot water cylinder is in the cupboard of one of the upstairs bathrooms giving a very low head of HW pressure to my two upstairs bathrooms (and low pressure downstairs too). My CW is mains pressure. What I would like to do is fit a...

Hi all, first post, I'm looking for some advice on upgrading my central heating/hot water system. I moved into my house a few months ago and I’m finding that my gas bill seems very high (using about £200 a month). It’s an old croft house built in the 1800’s so 2ft thick granite stone walls...
