Nuaire Drimaster location

ey143

Hi

I'm also thinking of Nuaire after seeing them at a trade show. A few questions:

1. What research has everyone done to conclude that this company was the better one to go gor?

2. One of the companies I saw (maybe no Nuaire) claimed that the product runs on less electricity than a light bulb which I could not understand because a normal cooling fan uses 30 or 40 watts, and for these devices to send air to around 5 or 6 rooms in the house, must surely use more wattage?

3. I didnt realise that PIVs have a heat option to - so it can send warm air around the house (like American houses)?

4. Does anyone know why Nuaire place their units in the loft to extract cold air rather than fresh air from outside? Other companies have said that taking air from the loft is silly and better to take fresh air as the temperature difference will not be huge.

Thanks.

Did you find that it made much difference?

Yes I thinks it did just by providing a flow of air.

answer: Nuaire invented PIV (positive input ventilation) specifically to cure and prevent condensation in houses and apartments

2. One of the companies I saw (maybe no Nuaire) claimed that the product runs on less electricity than a light bulb which I could not understand because a normal cooling fan uses 30 or 40 watts, and for these devices to send air to around 5 or 6 rooms in the house, must surely use more wattage?


the fan uses 5 watts of power to run, because there is no ducting running around the house like traditional whole house ventilation systems there is no resistance to the fan. the fresh air continuously mixes with the air inside the house to reduce the humidity level

3. I didnt realise that PIVs have a heat option to - so it can send warm air around the house (like American houses)?


answer: the heater option is only ot temper the incoming air ducring extremely low temperatures during the winter. the running cost of this heater is approx. £22 per winter season based on average outside air temperatures. this will not heat your house though.

4. Does anyone know why Nuaire place their units in the loft to extract cold air rather than fresh air from outside? Other companies have said that taking air from the loft is silly and better to take fresh air as the temperature difference will not be huge.


the units are placed in the loft because the inside loft temperature on average is 3 degrees warmer than the air outside.

Thanks.

Good points but wanted to clarify point 2. A standard fan will use between 30/40 watts but these are old fashioned motors. The nuaire fans use digital inverter motors that are similar in operation to a computer cooling fan they can change speed etc and use very low wattage to run. The drimaster on full speed of 6 uses 16watts which is great.

Quick question, I checked the humidity in my loft and it is around 75% so it seems that if I will install the Drimaster I would actually push more humid air into my house than I have at the moment(house has around 65% depending on the room) or am I missing something?

Now that is a very good point!
Is your lofts space fully insulated or is the warm, damp air rising from the bedrooms below?

As far as insulation goes, it is just the 6 inch or so of the insulation on the bottom, no insulation under the roof tiles only the black membrane. I don't think it is the damp air raising from bedroom/ bathroom ( in my opinion it is more about the location of the house considering that it is in Belfast )

lol
Its been a wet day there today then?
A very wet day?

Initially the air may be more humid but once it's been running a few hours to a day it will come right down to match what is outside, check the humidity outside.

currently Belfast humidity is 84%
that explains 80% humidity in my loft then , by the looks of it no point getting the Drimaster even though I really wanted to
