Hi all, renovating a room. It's been plastered, empty room, no carpet, using VOC free paint and primer and TVOC readings are still high. It was at 500+ earlier. Prior to the renovation, there was 2 beds, fitted wardrobe and carpet and at night TVOC levels would reach 2700!! There is rendering...

Hi all, I bought Tikkurila paint and primer as it's VOC free and had a lot of VOC in this bedroom. Room has been plastered and I have used Tikkurila primer. I did one coat and it was very patchy. Tried doing a second coat but it didn't make much improvement. I have now done 2 coats on the...

Does anyone if eco scheme installers fit anything decent such as Viessmann, Vaillant, Baxi etc?

I seem to be getting a lot of backfeed with CH and HW turned off. 132v on white and orange on 3 port valve. When CH is on demand I also get 240v on HW on cable to cylinder stat but HW is not turned on at programmer. Is this normal?

Fitted a PIV system and when it came to wiring it via lighting circuit, I checked two lights and both have one twin and earth cable going to the lights. The wiring runs via old black conduit to make life more difficult in the loft. See pic. Surely there must be some neutral and live...

Folks my seasonal problem has improved since I installed soffit vents to 2 sides of the property. However, twice in one week when HW goes off at set time on programmer the heating goes off too. When you try putting HW or CH back on nothing happens. If you leave it on, the pump eventually...

Looking to fit a PIV but my loft has 75% humidity I got heating pipes and tanks up there which are lagged except the cold water header tank. I've installed some soffit vents and that hasn't decreased the RH. I do seem to have a lot of loft insulation, will removing some help? Will the PIV...

Had 2 roof vents but unfortunately they have been fitted quiet low. Do I still need a condensate trap? The only location I can think of putting it is marked pink on the photo. Unfortunately it's an awkward angle going vertical slightly but most of it is a horizontal run.

Had a roof vent tile fitted and the attached pipe is 110mm and not 100mm. Is a 100mm available anywhere or it a job of using toilet pan connector as a reducer?

Just curiosity really, extension cables are known for causing fires due to being overloaded especially the 4 or 6 socket ones. What's the cable size in them 1mm? If it's down partially to cable size why aren't they made with 2.5mm cable (yes it will be pricey but safer).

Anyone any ideas on how I can remove scratches from stainless steel extractor fan?

Looking to fit 2 in line extractor fans on some plywood base screwed to joists. Any recommendations for something I can use to reduce the vibration / sound?

I am after 2 x new extractors, the dmev offers the continuous trickle option but their extraction rate is less powerful than an in line fan. Are there any inline fans in the market that offer humidity stat or continuous trickle? Also can rigid ducting be used for inline fan or does it have...

Looking to vent 2 extractor fans through pitched roof. I know you can get the tile vent type as well as the cowl. Which one is better?

I am after a PIV unit, however must seem to have controls on the main unit itself which means going into the loft to change settings. Is there any units that have a remote control or settings be changed on the landing by removing the cover plate? Thanks

Hi all, I've had a long term heating and hot water issue as my wiring centre is in the loft and the wiring does become oxidised and the hot water and heating intermittently come on. @Johntheo5 It has finally been diagnosed there's too much moisture in the loft. I have two extractor fans going...

Hi all some internal lights were removed and the person that did it turned off all the electric rather than the respective lighting circuits. Now the kitchen extractor fan doesn't work including the lights on the fan. However there is power coming into it as tested by the voltage stick. Any...
