mvhr

Hi, I hired a company to supply and install an MVHR system in my bungalow, and to say I have significant concerns about their performance is an understatement! Some of it I know enough about and am picking up with them (e.g. the 'fixes' to holes they've made), but I'm concerned about the...

Hi Everyone, I am exploring MVHR units and on the cusp of instructing Elite Renewables (based in Croydon), but I’m trying to find somewhere that I can listen to a system in operation. I’m based in Berkshire but at the moment the only system I could potentially get to is at their offices, which...

Hello, I am renovating my 1950s bungalow with a suspended timber floor. As you can see in the photo I've stripped the floors down to the joists, with a composition of external cavity walls, timber joists, a small sleeper wall, and air vents. I'm shortly looking to get started putting everything...

Hi all, We recently discovered that our MVHR system vents into a cavity wall, with the air then escaping through an airbrick on the exterior. We’re wondering if this setup is correct or if it could be contributing to a damp issue we’ve been struggling with. Background: We moved into our...

Hi everyone! We get a lot of condensation so had a PIV fitted in the loft a couple of years back. It has improved condensation on the windows a bit but does make the upstairs absolutely freezing (particularly over the past week). Thus, I'm no longer convinced that flooding the house with...

Hi all, First post here. Nice to meet you all! I have a Vent Axia Sentinel MVHR. (Manual here incase you are wondering). I have this system working on 3 bathrooms currently with a retractive "Boost Ventilation" switch outside each bathroom. The switch boots the ventilation up for 70% for 30...

Hi All, Does anyone have experience with this type of single room heat recovery units? Getting a lot of condensation in the bedrooms and seen these advertised. Retrofitting a full MVHR would be extremely difficult and expensive. We're in a flat roofed bungalow so not interested in a simple...

I am refurbishing an old house and am considering MVHR for 5 'wet' rooms only (3 bathrooms, kitchen and utility) with a single air return into the main hall void. The MVHR would only run for X minutes when a wet room switch was triggered. This way heat is saved, wet rooms are ventilated, noise...

I've just moved into a late-Victorian, mid-terrace property with a great space in the cellar that we want to use as a storage/utility area. While there is a useable drain, there is no ventilation to the space and I'd like to make sure I'm on the right track with my plans. Two surveys didn't...

I'm looking at the possibility of self-installing a MVHR (Mechanical Ventilation and Heat Recovery) into the loft space with the intention of increasing ventilation in the first floor rooms (1984 property). Having doing some research this is notifiable works and requires planning permission...
