Whole home ventilation system

Post by David Rites » 14 Dec 2010, 12:20

Still having problems with condensation and have come back to these units as a possible solution. Initially dismissed them as they seemed to be extortionate for what they were, and also didn't know how good they were.

If anyone has used them are they worth the money? Do they do the job? Are there any alternative products? Is there anywhere to buy at under list price, which I believe was about £400 last time I checked? Cant find any kind of review on the web to either recommend or dismiss buying one.

Thanks in advance

What's the original cause of the moisture in the first place? and do you know why your existing system cannot cope with this level? :geek:

Your loft should have air holes/vents at the soffits. Your cold water tank and pipes should be lagged/insulated.

If they're not you'd be surprised just how much condensation water is generated we are talking lots.

If you've put down loft insulation recently in the joists make sure its not blocking up your soffit vents

Thanks. I have even had a builder out and he checked the roofspace i.e. soffits and it looks OK. No insulation blocking it.

However, cold water pipes and tanks are probably not as lagged as they should be. Not something I've ever thought of - why does this cause problems? I'd be interested in hearing more.

As for laundry, along with 99% of the population we do dry indoors in the winter.

We also have a dehumidifier and bathroom extractor fans. House only has one air brick in the kitchen which I always wondered whether it should have more? All double glazed, and sadly not the type where you can open a vent at the top.

So its not perfect, but then neither are most households these days.

Has anyone actually used the lofty? I did ask a while back and somebody said he'd used a few to good effect.

Any other ideas?

Thanks again

Expensive waste of money, correctly addressed ventilation will cure all condensation problems , unless you use the home for drying laundry, in which case you condemn yourself to ill health. :evil:

I doubt your estimate of 99%.

However the people who dry their washing indoors are the ones who have excessive dampness and condensation.

If you weigh your washing when wet, and weigh it again when dry, each kg of weight lost is a litre of water released into your house. You might as well take a bucket and throw it over the walls.

However, if you like a wet house, or if you want to spend a lot of money on forced ventilation or dehumidifiers, please continue to hang wet washing inside it.

Hi Kevin,

Did you go ahead with the Lofty?

This has also been recommended to us as a solution to a condensation damp problem.

I'd like to hear from anyone who has had one of these units fitted with their advice/feedback. One concern I have is that the Lofty will circulate very cold air in winter and very hot air in summer, as the input is from the loft space.

The lofty is a "positive pressure fan system" and these systems do work - but only if installed correctly and if a proper survey is carried out and the system deemed suitable. They're not a miracle cure for all condensation problems.

There are other manufactures of similar systems.

If does not circulate cold air. If you stood right under the outlet (which is normally at the top of the stairwell) then you will feel a slight breeze, but you will not notice anything anywhere else in the property
