FREQUENTLY ASKED QUESTIONS
How do I operate the unit?
During installation your unit will have been set to run continuously at a level that will adequately ventilate your home.
As house sizes and occupancy levels vary, your DRI-ECO-LC has 6 speed controls which can be adjusted to suit your home.
How much does this unit cost to run?
To run the unit, electrical consumption would (typically) be about 1p per day. However, it should be remembered that the unit is making use of heat at ceiling level which would otherwise be lost.
The unit will switch itself into standby mode when temperatures reach such that condensation would not occur within your home eg. during the summertime.
What maintenance is required?
To maintain the optimum performance of your DRI-ECO-LC the filter must be kept clean and clear.
The cleaning or replacement of the filters is required every 5 years.
Can I install this myself?
Installing the Drimaster involves cutting a hole in your ceiling, working in the loft space, securing ducting, and wiring the unit to the mains. An electrician or installer can do this safely and neatly in a few hours. Once fitted, it runs quietly in the background with no maintenance needed.
✅ Typical installation time: 1-2 hours
💷 Estimated cost: £150-£250 depending on your location and loft access.
Once installed, the unit runs quietly in the background and requires no ongoing maintenance apart from replacing filters every 5 years.
Original price was: £389.40.£279.95Current price is: £279.95.
NUAIRE INVENTED PIV OVER 40 YEARS AGO
It has become the UK’s most popular alternative method of low energy, cost-effective ventilation!
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.
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.
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.

Hi Jeanette, thank you for your question
It would really depend on your personal usage as everyone would have different ventilation requirements. So far we have not had any complaints or negative comments regarding the energy usage of our PIV units but we cannot give an exact figure.
Kind regards,
I would like to fit PIVs in my HMOs however the bedroom doors are always closed. Will this prevent the positive pressure system from working?

Hi Kevin,
Thank you for your question,
It is fine if the doors are closed as long as there is a 1cm gap under the door frame to allow the fresh air to be supplied into the bedrooms.

I have installed the piv in my loft (it is secutred to a joist rather than hanging ) however, the unit is pulling a stale odour into the house so i have turned it off. i think its only been running for 3 hour s at the most. The reason for installing was to create a positive pressure in the house as i have odours coming in from next door. Im concerning the stale smell is actucllay also coming form enext door but my question is whether it take a while to cdraw clear air in from loft leakage points , and whether its possible to convert the current piv into one that vents directly outside ? Also does this model (I purchased in July 2023 just took a while to install) have the latest filters?

Hi Cathryn,
It would be likely that the unit is taking in the stale smells from your loft as it could be that its not well enough ventilated, the PIV unit works by bringing in fresh air from the outside. The filters need to be changed every year, but you say that the unit has only been used for 3 hours so the filters shouldn't be a problem. If you want to have a ducted unit then you would need to change the unit completely and then add the ducting.
I'm looking for a piv unit that can't be easily switched off or adjusted by the tenants, Does this unit have adjustments or a off switch on the unit?

Hello Jack,
Thank you for your question.
The Drimaster Basic Unit has the controls on the unit in the loft space and the diffuser in the hall will be blank. There is a remote monitoring device that can be used with the heated version of the unit or the basic Eco Link unit (No Heater), The remote monitoring device will allow readings to be taken from outside the property to determine how long the unit has been running and the operating speed of the unit. This will benefit the social housing provider when checks are carried out to ensure measures put in place to alleviate condensation issues are being adhered to, without having to enter the property. The product code for this item so you can see on our website is QS45554.

Hello Susan
Do you have extractor fans in your kitchen and bathrooms? as those are the main areas that cause condensation due to the wetness
If you don't have fans we would recommend getting our Kair smart fan for the bathrooms and kitchen.

Does this system negate the requirement for trickle ventilation in windows.
-
A
Many building codes still require trickle vents even with a PIV system to meet ventilation standards, as these vents provide a steady, discreet way to allow stale air to exit.
: A combination of PIV and trickle vents helps balance air pressure within the home. This balance is essential for effectively managing humidity and ensuring adequate air exchange in each room, especially in rooms further from the unit.
Hi I have the basic unit (purchased for you), I have noticed on colder days the cold air coming from the loft can be felt around the outlet inside the house and I'm sure is making the house colder (although it does work very well against condensation etc) - I now wish I had spent a bit more and purchased the model with the heater battery - is it possible to purchase the heater battery on it's own to fit to my existing unit?

Hello Dave,
Thank you for your question.
Unfortunately you cannot retrofit the non-heated version to a heated version. Please be aware, the heater is only 400w, so it will only take the edge off the temperature of the incoming air when it is cold.
Please come back to me if I can assist further

Can you turn the heater off on the unit and just have cold air.
-
A 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.Kind regards, Marc

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

Thanksanswer nowA Good morning Neil. It wouldnt 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.

QWill the basic nuadri unit cure the dripping wet bitumen felt in my attic especially noticable in cold frosty conditionsanswer nowA 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 Oncethe loft ventilation has been increased or reinstated (rolling back the insulationat several points or installing sections of open ducting to clear an air paththrough it) the installation of the Dri Master can go ahead and the throughflow of air to the void on the way to the dwelling will create air change andair movement causing surface evaporation and eventual drying of the void andthe dwelling.
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?

QHi, my friends are raving about this product and could you tell me would it be suitable for a cottage with a thatched roof . Thanks tinaanswer nowA Hello TinaYour question raises several others.Is the loft well ventilated through eaves or airbricks in gable end walls?The installation instructions do suggest inspecting the loft to see if you can see daylight in several areas or feel draughts? If the loft is not well ventilated the next question is can improved ventilation be installed?
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

I fear the pressure might build too much and make opening the door difficult! I can send plans over if that would be useful? Thanksanswer nowA Hello Joe The term airtight when relating to domestic dwellings should be taken in context in that they are only referred to as air tight for the minimising of heat loss, it is a building industry term in relation to that and that alone. There is no way a domestic dwelling can be truly airtight as 80% of the building material it is constructed from is air permeable. Your dwelling will also probably have key holes in external doors and possibly a letterbox, windows and doors have very good weather tight seals but they are not that good! You are building a home not a compression /decompression chamber.Dont be afraid of letting fresh air into your home or, for that matter pollutants out!The construction of your property will use a vast range preservatives and chemicals in the process including volatile organic compounds, found in building preservation materials, cement mortar, paints, lacquers and paint strippers, varnishes, waxes and intumescent coatings, all of this will be leaching out for many years after construction.You will also fill the internal environment with household cleaning supplies, pesticides (eg fly spray and moth repellants), air fresheners, and dry-cleaned clothing. Your soft furnishings will contain flame retardant chemicals and your carpets and possibly wooden floors will contain formaldhyde (new carpet smell).Now lets add in computers, printers etc (CFCs) or plain household dust (dirt and dead skin cells) without other possibilities such as animals and animal dander, radon gas etc. etc. etc.........Quite a toxic cloud and this is not to mention highinternal humidity, condensation and mould spores or dust mite activitythat has been identified to be one of the biggest contributors to the increasein asthma. Dont be too concerned over a couple of trickle vents contributing to energy bills or global warming, they can always be closed!

Will this unit stop this mould etc. or can you recommend something suitableanswer nowA Hello DavidThe product you have identified is a condensation control system for a whole dwelling and would be suitable if your dwelling suffered from condensation in several rooms.You have described the problem in your shower only so Qs?.Do you have mechanical ventilation in the shower room currently?If yes, how is it activated?Is it a cubicle in a domestic bathroom or has it been converted to a wet room?Does it have external wall/s? Your description of wiping down surface water yet still have a mould problem indicates that it is relative humidity (RH) that is the cause of the problem. Answers to the above will help us provide a solution.

I could not believe my eyes… Purchased due to bad condensation, with water streaming on all windows. Installed it – easy DIY Job. Next day: Woke up, cold morning 0 degress outside RESULT: Windows were completely bone dry. The Drimaster completely exceeded my expectations, I thought itd takes weeks and even then i thought results would be limited.
Anonymous (verified owner) –
I have bought a total of 11 of these and always found them to be reliable and effective. We recommend them to all our landlords with older houses with solid walls. They pay for themselves within a year with reduced tenant complaints about condensation and mould growth, voids and redecoration costs. Fairly cheap, simple to fit and they do what they say they do.
Anne Curry (verified owner) –
only been installed for 1 week but no sign of condensation.After drying living room window every morningwith a karcher it is a pleasure to see dry glass.also very quiet running.
David Robb (verified owner) –
I had no issues with fitting the unit, it is quiet when running, a bit larger than I was expecting.
Frederick Tompkins –
Exceeded my expectations do not hesitate buy today. You will not be sorry, cleared condensation for bedroom windows first day in use.
