Nuaire Drimaster location

ian103

We are in our second winter in a property with a nuaire drimaster, last winter we turned the drimaster off as it made the house cold. Unfortunately in autumn we had the first signs of mould, so as per a previous forum post, the nuaire is now on a timer, it runs 11pm to 6am, and it makes a vast difference, mould much reduced, (small patch remains in far corner of bedroom), condensation drastically reduced on window.

Would I recommend a nuaire - yes but if used in conjuction with storage heaters then I would restrict the hours of operation via a timer. I just need to work out how to change the filters as ours are old.

Does your drimaster have the heater element? Or is it one without a heater?
I do appreciate that the heater merely takes the chill from very cold air

The nuaire is old model, there is no heater, I did look at replacing with the heater version but decided that I'd try the timer option first as a cheap compromise, for us it works well, the heater version would be fairly expensive to run and would only raise the air temperature rather than heat it in my opinion.

My drimaster runs 24/7 but the heater part which is separately wired is connected to a timer and only runs at set times.

Have you tried with the fan speed turned right down and leaving on constant? This may get rid of the mould completly.

The heater as it only tempers the incoming air does not cost a lot to run as you are no heating a room with it the air is heated to 13c on mine and not 70c like a fan heater would. It's worth having.

We've had one of these fitted after dreadful problems with mould and condensation.. Although there are good reviews, it seemed too good to be true. It was fitted yesterday and we woke up today to not one bit of condensation on the windows.

I appreciate it's the first day, but I'm not on black patch watch to see if the existing patches dry up. We haven't tackled them for a few days as we want to make sure the unit is working in the 30 days or else we get a full refund from the supplier! Here's hoping it continues.

We are going to run the dehumidifier all day tomorrow out of interest to see how much water it collects..

Did you have the version that includes the 'heater'?
Or the one without?

Maybe it would be wise to run the Drimaster without the dehumidifier for a few days?
Only then will you be able to see if the Drimaster is working on its own.

They do work! the no condensation on the windows just shows that. What fan speed setting are you running it on? The dehumidifer will still be able to remove moisture from the air the air is always going to have humidity in it but a healthy amount that doesn't have to condense on Walls because the air won't hold any more. Let us know how u get on.

The nuaire definitely solves a lot of the condensation/moisture problem, the condensation on the windows is nearly eliminated so Id recommend the nuaire as a solution.

Not sure we can alter the fan speed on ours, guessing its a 2003 or so vintage, hence why I need to change the filters if possible.

I am thinking of fitting the Nuaire flatmaster 2000 in a few of my flats (they don't have attics) where the tenants have been complaining about condensation.

My concern is that I will spend a fair amount fitting them and the tenants will just turn them off for fear of running up big bills.

I have assured them it will only be around 10p per day but I wonder if this is a fact? Someone else mentioned 1.75 per day was more likely EEK!!! anybody with experience on the one with heat?

We are in Scotland therefore the heat option is preferred - I read that tenants turned off the non heated ones due to the cold draft.

Some of the properties don't have extractors in the bathrooms or kitchens and the Nuaire staff suggested that if I fit their system there should be no need for extractors?

All help appreciated

There should always be an extractor fan in a bathroom or shower room, you can sometimes get away with it in a kitchen but a cooker hood is best to extract to the outside to remove stale air, moisture and smells.

You can buy a decent extractor fan for £60 don't buy the cheap nasty ones. http://www.amazon.co.uk/Envirovent-Silent-Bathroom-Extractor-Humidistat/dp/B00E7UXIVM/ref=sr_1_7?ie=UTF8&qid=1422414129&sr=8-7&keywords=silent+extractor+fans for one with a timer and humidistat or for a basic one with a timer go for http://www.amazon.co.uk/Envirovent-SIL100T-Silent-Bathroom-Extractor/dp/B0080XNKQ0/ref=sr_1_1?ie=UTF8&qid=1422414129&sr=8-1&keywords=silent+extractor+fans

The heater is only 500w so it will pulse on and off to increase the air temp ever so slightly so it's not freezing cold. This heater will not run constantly for an hour it pulses on and off very quickly but if it did run at 500w constantly that's £1.37 in a 24hr period based on my tariff of 11.47p per KWH. Reality of it is you could prob halve that as the heater will only come on and off. I have mine on a timer to only run morning s and evenings for about 13 hours a day. So that's about 68p a day if the heater was drawing a constant 500w. Not very much.

First things first spend a bit of money on a decent extractor fan. I've covered in another post somewhere extractor fans cheap ones just don't cut it you need one that's gonna move the air. These are tested and move 26l/s which is perfect for bathrooms.
