MVHR feedback

Officer999

Hi all,

We live in a 4 bed detached house from the 80s which had an MVHR from an old Swedish model which doesn’t work anymore. We still have all the ducts.

We recently got a quote on replacing this old MVHR model with a newer version, it’s a Brink Flair 325. Includes a digital controller humidity sensor.
Have anyone any feedback on this? Or using an MVHR in general? Is noise an issue?

Our attic entrance is too small to get the unit into the attic so we’ll have to sort out that first.

Pay for an air tightness test before you do anything.

We have a vent-axia low carbon sentinel. It fits inside an upper kitchen cabinet. It works very well to keep condensation under control and in the winter it keeps the house warm.

On normal settings it runs at 30% fan speed which gives a low hum in the kitchen and a slight bit of vent noise. On boost the fans run at 50% which is audible in the kitchen and at all the vents - but not objectionable. At the moment it runs on boost most of the time trying to keep indoor temps below 20c, though this turn off in th late evening.

Love how it makes the house feel.

Noise is definitely an issue but you get used to it. It's just a low background hum.

I'm not sure how useful the humidity sensor is. The wet rooms will ventilate anyway so boosting the whole house just because someone's had a shower seems a bit wasteful!

How much is the Brink unit working out at it? Plus the cost of enlarging your attic entrance? You might find you can get another unit that would do the job and fit through existing ope.

Talk to someone like BPC Ventilation in Larne who do a large range of units, are competitively priced and deliver nationwide. If you're anyway handy you could probably fit it yourself!

I live in a bungalow and have had a Vent Axia Sentinel systemor 12+ years. Unlike other replies we do not hear any noise from either the inlet or exhaust ducts in the rooms.

The fans go to boost after showering, otherwise they run at 30%. One feature I like about the Vent Axia unit is when the house is warmer than outside, the fans reverse the flow to cool the house down. Not air condtioning though! This feature may well be available with other makes of fan.

Would noise from the ducts indicate a less than satisfactory installation, perhaps? We do hear some wind noise from the exhaust louvre outside when walking past it, but it is not intrusive.

just got in a Komfovent system from company called DR Air, very happy with system, running at 50 percent of max output, very quiet in all rooms, with these systems, cheapest is not always the best, best advice is to look at installations that companies have done, as mentioned above you need some form of airtightness for them to work effectively, feel free to pm if you want any more info
