Thanks.

Thanks for your replies. Seems a few of us have found that LED security lights fail unexpectedly early and very few examples (in this thread as yet) of outdoor LED security lamps lasting anything like 15000 hours. Haven't seen any LED security lights with a 5 year warranty though I'm picking...

Outdoor LED floodlights have been around a good few years now and I was wondering if my experience is typical... How are your LED security floodlights holding up? I'd like to know because mine aren't doing so well. I originally started fitting LED lamps as security lights on the outer walls of...

An update... Resideo suggested I factory reset the DT92E by entering installer mode so I did that on 13th Jan. Since then, the device hasn't automatically changed temp. setpoint - but it's only been six days. Time will tell. To be fair to Resideo customer services, they have made a real effort...

A 100mm Newlec extractor fan, with timer, was fitted into my (plasterboard) cloakroom ceiling about 7 years ago and despite light use, it's recently packed up. I've never been impressed with this device so I'm looking for a higher quality replacement that has a chance of lasting 10+ years. I...

Been investigating alternative wireless room thermostats to replace my troublesome DT92E and compatibility between brands is a minefield. Similar devices from more reasonably priced big names, such as Danfoss, have different wireless operating frequencies and, quite possibly, communication...

I'd like to but can I mix & match these heating control devices? The Honeywell CS92A and ST9420C are working fine and I'd like to keep them. Is there another reputable branded wireless room thermostat that could replace the DT92E and communicate effectively with the other Honeywell devices? Thanks.

Well, seems like the mother-in-law didn't exorcise that pesky poltergeist. I noticed the two radiators not fitted with thermostat valves were getting unusually hot this afternoon and and can confirm that the Honeywell wireless room thermostat (DT92E) changed it's setpoint again - from 19C to 21C...

Thanks for your replies, folks. I was wary of causing problems with the expansion vessels, having never done DIY plumbing on pressurised systems before. Thanks for the tips and good to know I'm on the right path. Agreed. What looks like PTFE tape beneath the 22mm connector copper pipe end in...

I have a twist & lock 22mm Speedfit-type connector (though I think it's a generic brand) on the central heating system and it has sprung a small leak so wish to replace it with similar. I would grateful for comments on my plans to carry out the replacement. The gas central heating system is...

Well, any malevolent spirits better watch out as the mother-in-law is due to visit over Christmas. Thinking about it, the cat has been looking a bit shifty...

Would appreciate views on this strange problem I'm having with a Honeywell wireless room thermostat (DT92E) that was fitted to my central heating system five years ago. Three or four times over the past five years the Honeywell DT92E appeared to change room temperature setpoint (increased by 1...

Yes. The LED lamp has a sufficient length of attached cable (of unknown rating) and I intended to use 3 core, 6 amp flex to wire the PIR - just because I already have some - even though the PIR has no earth connection.

That's an idea. The only place I could access the spur, without disruption and considerable additional cost, would be where the external junction box is sited. So maybe one of these could replace the external junction box? Or be positioned alongside it? I remember an electrician telling me...

Would appreciate guidance/advice on suitable amp rating for a cable I wish to use to wire an external PIR and an associated 20W LED light. Normally, I wouldn't need to ask such a simple question but I'm a bit unsure about my house wiring and think it may affect the current rating of wiring I...

Interesting, inventive approach. Prior to starting this renovation, I noted that rainwater had indeed seeped down the slither-of-a-gap between old putty and glass pane - probably accounts for why some of the old putty wasn't firmly held in place. But then it's been at least 30 years since the...

Would appreciate advice on choice of suitable primer... I painted a Crittalls window (i.e. zinc galvanised steel) last year using this Rustins water-based paint as a primer: https://www.rustins.ltd/rustins/our-products/speciality-paints/quick-dry-galvanised-metal-primer But I didn't like the...

Good point - I'd forgotten about the load thing. Yes, the load is currently 40W. I'll go with the standard lightswitch, thanks.

I have several G9 halogen bulbs used with a conventional dimmer switch and would like to replace the bulbs with their LED equivalents. I'm aware that conventional filament bulb dimmers are different to LED bulb dimmers and, ideally, I should replace the conventional dimmer switch if I wish to...

I take your point about duty cycle. I didn't think of checking the chime box, wiring and bell-push for a short circuit so will do that. Thanks. One safety question I forgot to ask: should the transformer (primaries) be protected by a low-rated fuse? Maybe a preceeding fused spur, or similar...
