Great thanks! That's what the vr33 that I mentioned in the first post is for, it adds opentherm support for valliant

Thanks so much now I understand. I prefer to use "Optimum Vibe" for the heating because I have the older non-smart/WiFi version of the same wireless roomstat, so wiring for the receiver is identical and they are cheap (£40 each roomstat-receiver pair) but have been working ok. This...

sorry hit send too early I'll try that again!

The 3 channel Wiser seems to report only two heating zones.

Thanks Wiser, like many other controllers, seems to be designed to control both single zone heating and hot water. In my case I have three heating zones (i.e. 3 real heating circuits each with its own motorised zone valves) and I want to add a controller to the hot water too, ideally a smart one...

Hi, I have a Vaillant Ecotec Plus 618 in a 3-floor 7 bedroom house with 2x 200L unvented cylinders and 3 central heating zones. The central heating has 3 wireless roomstats which I'm upgrading now to ones with wifi, but the hot water has no timer/controller at all and both cylinders operate...

We're converting the corner of a bedroom to a 1.2 x 3m en-suite bathroom (shower, actually). When we removed the carpet we found there's existing 11m ply lying on top of 28mm floorboards (original old timber ones, not T&G) which sit on 8" joists. The span of the joists is 5.5m. My...

The marks do only appear above the skirting and come off with some bleach.

It's an uninsulated 9 inch solid brick wall

We've got a first floor flat with some mould appearing just above the skirting. The tenant claims that it must be penetrating damp coming through the brickwork somehow - perhaps poor pointing. I can't see anything wrong with the brickwork except for a few pockmarks but I'm not certain it's...

Ok, good to hear and interested to hear any contrary views. I heard to many issues like the bulbs not dimming smoothly at low brightness, or buzzing dimmers or variety of other issues.

How do these work? Do they radiate heat out the front? (Like PAR16s might do?) Any links to dimmable products that can work? Also will the fire hood help keep in the insulation from being a problem assuming I use good quality bulbs?

It's difficult to change the number of fittings, not the type. They've wired it up for 9 fittings at certain positions. They're about to cut the holes for the fittings. I can skip some of the lights and do (say) 6 per room and use panel lights or integrated fittings if need be but it might to...

Indeed. I had tried to get this information about gu10s by reading previous threads but unfortunately the discussion was derailed by these two bickering. Winston1 in particular really ruined the OPs question in other threads in a similar fashion. If you're willing to help me and others, please...

We've completely refurbished and rewired our house, and allowed for 8-9 spots/downlighters in a six 4.7m x 3.2m bedrooms (2.45m high) and in hallways and bathrooms. The ceilings have about 25cm between plaster and floorboard including fairly high grade rockwool. The wiring is already done (9...

Thanks for all the replies. I've checked with my own level and it the floor does seem level. I didn't check closely enough for bulging around the fixings so I'll do that tomorrow and report back. It does seem like it was "only" a day or two of there being a large gap in the roof. Over 23...

In the middle of a home extension which includes entirely new roof, and new joists and floorboards. Before the xmas break they left the ridge tiles and other gaps in the roof, and no scafolding with cover, so it wasn't weatherproof. With the recent heavy rain we've quite a few days of rains...

[/url] Thanks, sounds like it! But will it work? If you slather the roof end-to-end with the stuff will it protect it against the elements for many many years?

I manage a freehold property and a 99-year leasehold tenant on an upstairs flat has a leak in the corner of her bedroom. I went up on the roof and it definitely needs urgent attention. The felt has bubbled up in a few places and lead flashing loose at several of the edges. In particular it...

I've got some builders refurbishing a flat that has rising damp - the concrete floor was measured as very damp all over and apparently was laid almost without any damp proofing. We got a damp guy who injected a new DPC and rendered the walls about 50 cm high (till 20cm above the DPC) with a...
