    Vaillant ecotec plus 438 no heating or hot water

    The heating does get used in April and September too when it's slightly cold too. It's not just the heating not coming on in colder months but the water too. The readings won't be different from colder months or warmer months. The issue is condensation and oxidisation. It's only worth checking...

    Vent types for venting extractor through roof

    Don't some tile vents come with a flexi hose attached? The extractor pipes are 100mm guessing you need an adaptor for the 110mm?

    Vaillant ecotec plus 438 no heating or hot water

    I've already done that. As stated the issue happens in colder months. There isn't a fault with the system, pump, valve or boiler. What I meant the loft gets condensation in the colder months and one of the wires becomes oxidised due to the condensation. If a cylinder stat is faulty will it...

    Vaillant ecotec plus 438 no heating or hot water

    The legendary problem has returned. I have been advised it's due to condensation in the loft. And today the loft had 55-60% relative humidity but had not heating or hw. The garage had 60-70% where the boiler is located. I've bagged up the wiring in the loft and put a plastic tub over it too...

    Dmev fan vs Inline fan

    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...

    PIV system controls

    Which brand do you have? The nuaire ones seem to have different speeds. Surely you would need a different speed for a large property compared to a small 2 bed house for example.

    PIV system controls

    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

    Vents for eaves and tile vents

    Thank you for that. It's awkward to get 4 inch elbow out of that. Not a fan of the loft as it is! What about get some vents for the eaves? I got some flat roof I can stand on from the outside, are they easier to install? If you are venting straight through the roof would you use the...
