Hi all - my first post so be gentle!
Planning on putting a decentralised mvhr system in our master bedroom (basically a fancy pants extraction fan that recovers some of the heat from exhausted air and uses it to heat incoming air). The reason behind this plan is that the layout of the house (a bungalow) is a bit weird having been added to over the years.
The master bedroom is at one end of a corridor and tends to suffer from what I’d describe as ‘dead air’ – even with the window open (not ideal in winter as the house is already pretty cold) – and is normally quite stuffy. It is also at a fairly permanent state of high humidity – there are (seemingly) no obvious leaks in any plumbing or wet patches so I’m assuming it’s because there are two adults (and a toddler depending how the night goes!) sleeping in there. Currently run a dehumidifer in there which has stopped any mould but is fairly noisy.
I’m hoping the dMVHR system will make the room less stuffy and less humid. The system I’m thinking of is a Prana one from ecostream (https://ecostream.org.uk/recuperator-prana-210g-erp-pro-mini/). Ecostream will install for a few hundred quid (whilst I could do this, I’m not keen on drilling at 21cm dia hole in my wall and ensuring that it’s slightly sloping.
Anyone have experience of doing this kind of thing? Good idea / terrible idea?
In my mind I’d ideally install a PIV system near the room but there is a storage room in the loft above that prohibits this. I’m reluctant to drop 6k on a full MVHR system. I’ve contacted ecostream but they don’t seem great at recommending solutions / answering questions.
House layout below - not particularly airtight, tho i've done what i can. Concrete floors with cavity insulated walls.
