    What product to use for chemical flush?

    What product to use for chemical flush?

    It's both really, depending how much lockshields is open on the rad. Do you mean metal brackets for hanging radiator on the wall? this particular rad has been replaced in April, don't expect it to be completely choked up

    What product to use for chemical flush?

    Hi, Have been having problems with few noisy radiators, particulary one in master bedroom which wakes us up when heating is on. Also most of rads are not hot at the bottom. Obviously all rads are bled and reasonably balanced. Oil central heating, conventional boiler. Old copper pipework that...

    Water on extractor fan and shower ceiling.

    Outlet seems ok, air blowing out of it. I agree about hose layout, but because where builder made a hole in the wall highest point is in that wall, not sure how I could improve it...

    Water on extractor fan and shower ceiling.

    Hi all. Trimmed the door in the shower room so it's around 20mm gap, little to no improvement. Wrapped flexi ducting with Thermawrap and also insulated it further by covering it with loft insulation - made it worse, water started to collect on the fan much sooner now. I'm at my wits end now...

    Water on extractor fan and shower ceiling.

    Can I ask you why would you not bother with insulating ducting? In-line spec mention that ducting run should be 500 mm minimum, so would you still disregard it? How critical is last point? Gap is way too small, but i suppose i can always open the window a bit or in winter leave the door slightly...

    Radiator pipework connections

    That would be six access hatches in total as there are three radiators. I just want to know how secure compression connections would be, it would be shrouded for natural movement and changes to pipe under different temperatures. I would run heating for a few days without covering it in...

    Radiator pipework connections

    Hi, We live in a 1960's bungalow that we move in recently. We got recommended local builder, who is doing rooms completely - plastering, painting, skirting boards etc. One of the jobs was to replace old radiators for new ones, which involved modifying pipework in the concrete floor (btw, old...

Switched off led, working now, hopefully will stay like that. Tomorrow will write email to Honeywell...
