    Solution for mould and condensation

    We've had quite a few discussions on PT about mould and condensation problems.

    At the Welsh Landlords Day, we came across Nuaire and thought it worth finding out about their cost effective products to combat this problem.

    My parents bungalow had been plagued with mould for several years in a rear bedroom, and we've spent hundreds on different remedies and redecorating over the years. I came upon Nuair during a google session, and after a bit of research purchased the Nuair 2000. Took around 3 hours to fit, and the difference was noticeable the following day. Windows that had previously streamed with condensation were clear, no musty smell etc. Its been in around 6 months now, and not a sign of mould. Fantastic product.

    We put a Nuaire Drimaster in one of our houses where there was a mould problem (also replaced the bathroom extractor fan at the same time, so that would have been a factor too), at the beginning of last year. It made a big difference. Got it fitted by a local electrician and it worked out about half the price of the big-name competitor we'd originally got a quote from. Tenant grumbled a little about the cold air coming in when the weather was very cold (vent had to go on landing right in front of bathroom door due to headroom issues in the loft) but did seem to appreciate the difference.

    The “big-name competitor” has a small heater in their system that only comes on when the loft air is very cold to overcome the problem of the cold draft. My mother in law has one fitted in her small bungalow and thinks it is great as it solve all her condensation problems.

    When we moved into our large detached bungalow we had lots of problems with condensation, but as the layout is complex I did not trust that a “positive air input system” would work, so I fitted a “Heat Recovery Ventilation System (MVHR)” that worked very well. Since I have fitted it we have not even had a mirror steam up in our bathroom.

    For a rental property I would put in Positive Input Ventilation (PIV) as they cost less than MVHR and work very well for small properties.

    The Nuaire Drimaster Heat model also has the heater element to warm incoming air. More expensive to operate though.

    Yes, I considered that one (obviously cost a little more, but would still have worked out not much over half the total cost of t'other), but the company selling it advised me that it's much more efficient to heat the air using the central heating system once it's inside the house. I believe you can also retrofit the heater unit if you belatedly decide that you need it - though it's much more expensive to do that way.

    Unfortunately our tenant had been sold on the "costs 1p a day to run" argument presented by the salesman (I mean surveyor) - not realising that that didn't take the heating part into account.

    This shows a very interesting problem...

    If someone feels warm and comfortable they may be willing to run the heating at a lower temperature. So drafts etc can increase heating costs by a lot more then what the physics would make you expect.

    Therefore I am happy to use a little expensive heat (electric) to make someone happy with less cheap heat (gas) – but it is very head to measure this sort of thing, as it is different for each person.

    Yes you can retrofit the heater, but as you say its more expensive to do it that way. We've been more than happy with the standard model, and at nearly a third of the cost of another make.

    I'm glad to see this. I used Envirovent on a property with damp issues. The good news is that their Cyclone fan (the inline version, so fan in the loft) is very powerful and mostly resolved the damp issues in the whole property. But the downside was dealing with Envirovent. What an awful company. I was told their "best engineer" was coming, but he then resigned (!) and the guy who came was pretty fresh, made mistakes, and getting the system fully working (one fan!) took *five* engineer visits which was just a total pain in the backside. To their credit they wrote off half the cost, but the sense I'm left with is that their products are good, their approach to customer service is not so good.

    Next time I think I'll take a look at Nuair. I do think these ventilation systems are the right way to go where there are persistent damp problems. It's not good enough to just tell the tenant to open the windows, no-one should be expected to do that in winter.

    Firstly I am no expert....
    Mould and condensation - stars of 1960's built bungalows and older properties where tenants don't open windows and crank up the heat!
    Vapor on windows is beyond treating as water vapor is extreme condensation.
    Why did I have to learn this as a landlord/investor?
    IF i had installed the correct vents in kitchens and bathrooms(oppose to the cheapest) and had 10mm gaps under the internal doors I would have none of it - Why it took a rep (who knew he wasn't going to get a commission) from 'Vent Axia' to explain this - not expensive via power discount llp. So £210 a house and £5 electric for the year to run in electric - yes the Humidistats are on 24/7/365. The freshness in the air is brilliant - No more stale air and lo-carbon products. They increase room temperature by roughly 2%.
    Anti fungil spray - the only spray that works to kill and break down the mould - Polycells £3.30!
    As for the comment about envirovent - I second it from another angle - cost to me and the electric for the tenant (Approx £70 ) - I still have plenty of
    money left after 7 houses compared to their 2. The joys of franchising.
    As for Nuair - Sorry I don't know.

    Hi, I know this is an old post, but did that solve the problem long term ?

    do your properties have central heating ?

    Excuse my lack of knowledge but what are lo Carbon products ?

    So power discount llp advised you ?

    thanks
