    Dehumidifier running

    If you're getting bad condensation and humidity issues a longer term solution is putting in a PIV (positive input ventilation) unit. These normally sit in a loft where they draw air from the space, filter it and blow a constant stream of air into the house. The idea is this creates positive...

    Downlight

    Google search 'triangular led under cabinet lighting', lots of options out there, just be careful to match the 12vdc voltage and the colour temperature to the others

    Electric shock from double socket

    While a fault with the actual socket is unlikely they do occur so don't discount the possibility, I had one a while ago that internally shorted L&N when switching it off. If your socket had an internal fault that shorted L to E when switched, it is possible the user would feel a shock before the...

    LED driver with no cable grip

    In the end I've just secured the drivers in place and clipped cables well either side, and they're ferruled up, screwed in nice and tight, not going anywhere. The drivers are from a well known national wholesaler, I was disappointed to see they have no cable grips on the ELV side but they appear...

    LED driver with no cable grip

    Hi all, I've got some LED drivers for LED strip that I'm planning on putting under kitchen cabinets, both branded Saxby lighting, which I thought is fairly reputable. The drivers will go on top of the cabinets, fairly standard installation. The problem is the LED drivers don't have any form...

    Nightmare airlocks on open vent heating system

    Agreed. Not my doing I will add! Just wanted it working for now and when the house gets fully gutted and redone in 2 or so years the plumbing will be completely started again from scratch.

    Nightmare airlocks on open vent heating system

    Red circles show my new AAVs and the manual air vent. The higher AAV is on a high point return leg that covers all the rads but not the cylinder. The lower AAV is on a high point flow on a flow leg covering 4 rads, was hoping there would be enough flow through these to look after any stuck air...

    Nightmare airlocks on open vent heating system

    Just an update, managed to finally get it working today, installed 2 AAVs on pipework where it looked like air could collect, there is also a manual bleed valve as well nearby. Still no luck with filling the system conventionally via the F&E tank, so again I back fed mains water through the...

    Nightmare airlocks on open vent heating system

    Sounds like a sensible plan was thinking a little distance after the pump and before the zone valves might be appropriate for one. Second one perhaps on the return but before or after the bypass valve connection point?

    Nightmare airlocks on open vent heating system

    Cheers, I had done that so in theory water should have been able to flow around the system

    Nightmare airlocks on open vent heating system

    It's been temperamental from day 1 since I've owned it, there was usually 1 rad (it varied between a couple of them) that wouldn't get warm, but sometimes they all would. We knew there was air problems due to constant gurgling in pipes and often the boiler would lock out due to air. Sometimes...

    Nightmare airlocks on open vent heating system

    Will get pics tomorrow, btw the plumbing in general is an absolute mess and will be completely renewed in some years. However think it is 'correct' Will try and check for blockages tomorrow as well, the pump impellor manually spins easily and also spins electrically (can hear and feel it) it's...

    Nightmare airlocks on open vent heating system

    Cylinder coil - yes, there is a manual air vent connected at the top of the coil, just bleeds water no air. Its the only air vent around tho, perhaps some AAVs would help? Magnet - I know the F&E pipe isn't blocked as I've seen the tank empty rapidly with the main draincock open, but good shout...

    Nightmare airlocks on open vent heating system

    Hi all, Got a nightmare situation with a central heating system I recently adopted. It's an open vent S plan system with a combined F&E pipe, with a Worcester greenstar danesmoor 18/25 oil boiler. Covers 10 radiators mostly large double panels, some towel rails and smaller rads too, as well as...

    Does this oil pipe need bonding?

    Hi all, Recently had an oil boiler moved to make space in the room, the plumber that did it insisted that the oil pipes need bonding however I'm not so sure. Property has TT earthing. My understanding was that pipes generally only need bonding if they are extraneous, i.e. are metal and run...

    Atag boiler seems to ignore set flow temp

    Hi all, I've got an atag IR24 conventional gas boiler. Recently due to the warmer weather, I turned down the set CH water temp to 70⁰C rather than the 80⁰C we set it to for the winter (might seem high but we need it fairly high as the rads are on microbore pipe and don't get hot quickly enough...

    Best LED Lamp/ Dimmer Combo

    Recently used a V Pro paired with Philips warm glow lamps, no flickering or buzzing and they dim nicely, however it does take a second or two for them to actually switch on, not a problem with the lamps, have tried various lamps they all take a while to come on

    Smoke alarm placement

    Hi all, I'm helping my friend do up an old house he bought a couple months ago and obviously we need to have mains powered smoke detectors installed. I'd just like to ask a couple of questions about the type we need and their placement. Firstly the upstairs landing is literally about 1m^2 and...

    Using kingspan/celotex in place of fibreglass insulation in a loft

    Yes I'm certainly aware that it's expensive! I would have just gone for soft insulation and loft legs and just cope with a small amount of headspace but he (and the Mrs) are pretty set on wanting to use board insulation. We could go up to 120mm as that's the joist width but it seems harder to find.
