    Vaillant Eco tech 624 system boiler not heating water.

    Update. Repair man came today. 1. Said hw control valve was broken, so replaced it. But still no hot water. 2. Said air lock in primary coil so tried to vent and bleed. No good. So then tried to "drag" water up to the cylinder via a hose attached to the vent of the primary coil. Still no...

    Hi, We have an Eco tech 624 plumbed as a system boiler. It has a pressurised hot water tank in the loft for hw. Come back off holiday to find that the boiler appears not to be heating the hot water. It fires up for the programmed time but no hot water. Non of the control knobs have been...

    Plumb sure 15x10 internal reducer

    Hi Bought some internal reducers for converting my 15mm rad valves to 10mm pipe. Was a little confused by this brand and the set is one piece, rather than two piece and an olive. I finally worked out that this one piece type does not need an olive, even though the instructions on the pack refer...

    Very heavy radiator

    Hi Trying to hang 48 kg rad to brick wall. 3 brackets appear ok, one is going into either mortar or a very poor block. Tried moving the bracket but still the same problem. Any ideas? Also a bit concerned with the screws and plugs supplied. Are wall anchors ever used. All good advice...

    Hinge spacers on UPVC door

    Thanks for the suggestion and link. Possibly could work but I would prefer to make my own spacer so it would be white and match the profile of the hinge. Pity I cant get an answer as to why such a upvc product does not exist. I wonder if the concern in cantilevering the door off the frame...

    Hinge spacers on UPVC door

    Hi Im told that nothing exists what so ever to pack out flag hinges from the door and its frame on a uPVC door. After some alterations a uPVC door no longer opens much past 90 degrees as the hinges hit the new surround - effectively the door is set too far into the wall now. A simple solution...

    Thanks. Keeping the insulation and pb separate does make a lot of sense.

    Insulating under ceiling

    Hello. My kitchen has a side extension with a pitched roof about 25 years ago, before we moved in. Upon investigation there is minimal insulation above the plastered ceiling. Above the "existing" / "original" kitchen ceiling is a bathroom. The roof space above the extension is well ventilated...

    Hide Flat Roof Edge?

    Hi I'm planning a flat roof orangery style extension. I'm looking for a fascia and ultimately a gutter system that will hide the edge of the flat roof. Essentially I'm thinking there must be a gutter profile available that is higher on the outboard edge than the inboard??? Any advice?? Thanks...

    Insulating kitchen Ceiling

    Hi I have a side extension to the kitchen with a pitched roof. There appears to be about 75mm of loft insulation above the plaster board. With 8 poorly fitted downlighters the thermal insulation of this ceiling is quite poor. I wish to improve it. Im thinking of simply adding 100mm of celotex...

    Honeywell ST6400 To Hive & Removal of old thermostat

    ok Thanks to You Tube, I appear to have got the Hive up and running! BUT, what do I do with the old wired thermostat? The thermostat is not wired to the old programmer so not to the new Hive backplate. So is it wired direct to the boiler? I presume I need to remove it? So, how? Hope to get...

    Honeywell ST6400 To Hive & Removal of old thermostat

    Hi Just started self installation of HIVE. Removed Honeywell Dual Controller for CH and HW. Found only eart, Live neutral and two other wires for CH on and HW on on pins 3 and 4. I also have a wired thermostat which I presume wires direct to the boiler and not the programmer. HIVE...

    Loft Conversion impacting on HW decisions - HELP!!

    Hi We currently have a system boiler that was installed in 2007 with an open vent cylinder in the loft. We are having a loft conversion. So originally thought about a closed vent cylinder to feed hw system linked to existing boiler. Some plumbers now advising on replacing a perfectly working...

    Improving insulation

    You are right about the chimney effect! Not sure what you mean about "tiles off" its a plasterboard / artex ceiling. How about I cut a big hole in the plaster board big enough to stand in to lay foil type insulation over the top of any existing. Then patch the opening and skim to new? Or as I...
