The DRI-ECO-LC is our basic unit which provides all of the benefits of Positive Input Ventilation, offering system controls on the unit within the loft space.
Whilst the controls offer variable options, when the Drimaster is installed the system should be set to a speed that is suitable to the property meaning access to the loft is only necessary for the replacement of filters.
The DRIMASTER-ECO range provides whole home ventilation using the Positive Input Ventilation principle, which introduces fresh filtered air into the dwelling at a continuous rate, encouraging movement of air from inside to outside.
A large range of models are available - Please see our table below. Please note, it is not possible to retro-fit a heater to other Drimaster Eco models.
It has become the UK's most popular alternative method of low energy, cost-effective ventilation!
Invented by Nuaire and installed in thousands of dwellings each year, PIV can be a more cost-effective and simple to install ventilation solution, whilst still meeting building regulations.
CREATES A HEALTHY LIVING ENVIRONMENT
MOISTURE AND CONDENSATION ARE DRIVEN OUT
The filtered air gently pressurises the home from inside out, forcing out the stale air.
NO NEED TO OPEN WINDOWS TO VENTILATE
Clean, fresh air is continuously drawn in through the lofts natural leakage points, passed through the filters and fed into the property via a central hallway diffuser.
Always get a qualified electrician for fitting the unit!
The unit is supplied with a pre-wired power supply. This power supply unit has a metal bracket incorporating fixing holes, which should be used to fit the power supply to a suitable surface, e.g. a wooden joist.
The fan unit is also supplied with a fused spur. The 3 core mains cable from the power supply should be connected to a fixed wiring installation, via the isolator, via the spur, in accordance with current IEE wiring regulations.

Hi could you tell me the outlet size on this unit, I have to split it between two existing vents as I don't have enough space on landing due to loft hatch and smoke detector. I have also found this same unit on eBay for 260, from mould stop. Do you do price matching. Many thanks Michael
Hello Michael
My shower suffers from regular mould and damp and has to be cleaned once a week to stop this although the shower is wiped down after every use. Will this unit stop this mould etc. or can you recommend something suitable
Hello David
Hello I have condensation in the loft, I have a de-humidifier in there and its collecting over a litre a day, I would like to know if you do a system that actually collects the water and runs it to waster
Hello David
I would suggest you look up the make and model of the dehum you currently have and see if you can download a datasheet as I believe most reservoir machines already have a continuous drain option.
Your condensation problem in the loft is most likely due to lack of adequate ventilation so checkto ensure that the loft has adequate ventilation. There may be occasions wherea loft is so well sealed that additional ventilation may have to be provided. Ensure that all water tanks are covered and sealed. Checkthat all water pipes are lagged. Ensure that any extract fans are dischargingto outside and not into the loft. Check that the loft hatch is tightly sealed.Ensure that all holes in the ceilings are sealed i.e. ceiling light fittingsetc
Oncethe loft ventilation has been increased or reinstated (rolling back theinsulation at several points or installing sections of open ducting to clear anair path through it) the installation of the Dri Master can go ahead and thethrough flow of air to the void on the way to the dwelling will create airchange and air movement causing surface evaporation and eventual drying of thevoid and the dwelling.
I am planning on building a new house soon and I had hoped to make it as airtight as possible. As a result I do not want to use trickle vents but an MVRH solution seems expensive and the duct runs could prove problematic with the current plans. The PIV solution seems to be ideal but I am intrigued as to how the stale air / moisture will be pushed out the building if it is so air tight? I fear the pressure might build too much and make opening the door difficult! I can send plans over if that would be useful? Thanks
Hello Joe
Hi, my friends are raving about this product and could you tell me would it be suitable for a cottage with a thatched roof . Thanks tina
Hello Tina
Hi there, we have a 2 storey stone cottage with stairwell and loft and a single floor extension to the rear with several extra rooms. Will a single unit in the loft serve the whole house, or would we need to provide a second duct to the extension? Which model would be appropriate?
Will the basic nuadri unit cure the dripping wet bitumen felt in my attic especially noticable in cold frosty conditions
Hi Lyn
What you describe is condensation and the indication that you have condensation in your loft points to a lackof ventilation to the loft void, inspect from outside to see if you have slateor tile vents, or ridge tile vents, if there are none the loft ventilation mayhave been provided by overhanging eaves or soffit vents, if the last two,condensation problems can sometimes be a result of loft insulation being rolledtight into the eaves cutting off this means of airflow.
If you installed the Dri Master under these circumstances it would not controlcondensation in your house or the loft as the means of drawing air into thevoid are not sufficient for either.
The installation instructions for this unit begin with the loftinspection below.
Checkto ensure that the loft has adequate ventilation. There may be occasions wherea loft is so well sealed that additional ventilation may have to be provided bythe owner/occupier. Ensure that all water tanks are covered and sealed. Checkthat all water pipes are lagged. Ensure that any extract fans are dischargingto outside and not into the loft. Check that the loft hatch is tightly sealed.Ensure that all holes in the ceilings are sealed i.e. ceiling light fittingsetc

hi can you tell me the best position I should put the NUADRI-ECO-LC in my home
Hello Maurice
If we install this in the loft but at a later date want to change the loft into a room can we box this in but still allow it access to outside air? Also would this device need clearance around it (im thinking if we put an enclosure around it)? If we did box it in couls we put tile vents in to allow the device to bring in outside air? Thanks
Good morning Neil. It wouldn't be advised to box it in, as it needs to draw fresh air into it. If you are creating a room in the loft, you would need to consider where you will be installing the Drimaster. You may well need tile vents to draw in the fresh air. It might be worth consulting Nuaire technical before purchasing the unit, just to be on the safe side.
Hello, Please advise when I will receive this order. Thank you
Hello Michael
Can you turn the heater off on the unit and just have cold air.
Good morning Dennis. The DRO-ECO-LC does not have a heater. The only models that do have a heater (presuming the property is 2-storey) are DRI-ECO-HEAT-HCS and DRI-ECO-HEAT-HC. The latter model has RF, so if you purchase the additional 4-way switch with it, that will allow you to disable the heater. The only other way would be to pull the plug out from the heater, or you can turn the heater dial down to 5 degrees. The Fan normally goes on Standby when the temperature drops below 5 degree C.
