Dampdaveski - Help

Hi dampdaveski or whoever else can help, can you please tell me the difference (exactly) between the Drimaster standard and the drimaster 2000 version besides price.

Cheers

Answered in Pm's. Thanks

my pleasure Marsh
just in case anyone else needs to know, as some people think they are a glorified fan in a box(though there is an element of truth to that)
Ignoring the principles on how they work and full specs etc, the fundamental difference between the 2 is as follows
Standard Drimaster
This has fixed temperature heat recovery, so when the temperature in your loft rises above 19deg c the unit will speed up automatically to get the warmth (if any)from the loft into your house
Drimaster 2000
this has intelligent heat recovery, so basically there is an additional sensor that goes into a bedroom or room seperate to the hallway, and as soon as the temperature in the loft is 1 deg c above that of the house, the unit speeds up automatically. You can also fit a manual boost switch which is placed inside the house (usually in an airing cupboard etc), you would use this to manually place the unit onto full speed, say when its mega cold OR you've had the kitchen in use for sunday dinner or bathroom in continous use etc.

Either unit will control your condensation problem perfectly well, both have the same output and speed settings.
I have a dri 2000 in my house and to be honest you don't notice the heat recovery at all, I don't have mould or condensation though.
The heat recovery on both units is independantly tested and proven, both units have their BBA certificates etc, but as i've stated you don't notice in day to day use.
Also the envirovent loft unit works well, but is more expensive, even the lofty works (but IMO is cheap and nasty), the johnson and starly unit works ok (see lofty comment), the xpelair model is an envirovent mk1 model (see lofty comment again), Daisy unit, hmm (as lofty comment)

For all the thread raggers out there I DO NOT work for nuaire, I buy their units and install them (as well as other suppliers) for my own company. It is my choice to remain anonymous on here, I don't come on here to advertise myself or my products. I have given my suppliers details out plenty of times in the past and have received as a one off a bit of extra discount as a thank you from them as they've had a bit of business from here, they don't rip people off, are competitive and as a consequence of that I have no qualms about getting £20 knocked off an order.
Think i've spent too much time on the vent thread (I'm getting all defensive lol )

Live long and prosper

Dave can you let us have a link to or details about the manual boost switch, I called Nuaire about a remote switch and the bloke on the phone said they didn't do one!

They also never explained the 2000 sensor to me properly other than it's a few LEDs to let you know if the unit is working OK!!

We're got the 3S model and I'm sure the different diffuser on these models gives a different air flow, have you had any experience with this model?

I'm going to have to move the bloody thing anyway as it doesn't clear all the condensation in one bedroom!

Thanks

Hi, had mine for nearly two weeks now and our bedroom was flooded (well slightly OTT!!) this morning. Got the dehumidifier running again which has annoyed me TBH. I think ours is not really doing much at all. Maybe ours needs moving too but there is a blummin large hole in the ceiling then??

To those saying it isn't clearing condensation in certain parts of the house, did you install the units yourself/with the help of an electrician or have a specialist contractor like dampdaveski spec them & the location? A contractor should be able to tell if the property is too compartmentalised (fire doors or just doors that are always shut) or spread-out to be sorted from a single loft unit and should have considered whether a through-the-wall unit should have been installed in one particular room...

2Sheds, Marsh
the link to the fitting instructions that has the boost facility mentioned is -HERE
The 3S model is exactly the same as the normal model except that it has a 'fire' collar to comply with the regs.
Don't move it, just try increasing the speed, ie press the little button ONCE and it will increase the speed setting by one (unless it already on full speed then it will place the unit on setting 1).
If you're still getting bad condensation then it is possible that the ventilation in your roof space might not be adequate, OR you might have a badly fitting loft hatch (this will basically allow the unit to recycle existing moist air).
Do you have spotlights in your bathroom? if it's on the 1st floor these can let an awful lot of moisture into the loft if they arn't sealed correctly.

Marsh you paid for someones expertise and they installed the unit, call them back and get them to sort it. Your unit might just need turning up a setting, the loft ventilation might not be adequate, however they surveyed the property before they sold you it, they should of assessed it
Biggest issues I generally find are
Loft ventilation, draughty trap hatches and spotlights in bathrooms that arn't sealed
hope this helps
