I need to change an existing Danfoss 103E7 Timer. However, in spite of having the installation instructions for the Danfoss, I cannot work out how to remove it to access its backplate. The instructions for the Danfoss suggest a screw visible at the base of the unit, but I cannot find it...

I have an old Wylex Fuse Board installed in 1970. It has never been changed because there have never been any extensions/modifications of any note. A recent lighting fuse failure (caused by the demise of a CFL, not a wiring problem) made me look into MCB replacements for my fuse holders. I...

After being away for 2 weeks, I started up by my (open vented) system and no heat. There was a mains feed to the pump, but the pump appeared to be stalled (no vibration). I unscrewed the vent plug about half a turn. This caused a small water leak, but no air release as I recall. However, the...

I am proposing to upgrade my existing radiator circuit to something like modern standards (something I feel I can do myself) as part of a long term plan to replace the boiler as well (something I will need a plumber for). For the radiator circuit, I am thinking of using Honeywell 'S' Plan so...

I am proposing to change my bathroom radiator (installed 1970) for a towel rail, which will be in 15mm. Examination under the floor shows the flow end being piped with 1/2 inch copper; I anticipate no problem connecting here. The return end is piped in 1/2 inch BSP pipe (OD 21mm), with a...
