Hi I have a Drimaster installed at a rental property which has an inbuilt heater with thermostat and is controlled by a remote Humidistat so is only activated above pre-set humidity level. I need a Flatmaster for another property without loft space. I can't find reference to Humidistat control for Flatmaster. Do you supply/recommend one?
I require a 100mm unit which has a square intake of 215mm. If this fan is not suitable can you recommend one which is. There is a 5m horizontal run on the vent pipe plus a vertical run of 3m. Thank you.

Setting the Temperature Speed Control Option
In the instructions it says the following under Setting the Temperature Speed Control Option: 1 (Default) At loft temperatures below 19°C the unit will operate on “Normal Operation Mode”. At loft temperatures above 18°C but less than 24°C, the unit will switch automatically to “Intelligent Heat Recovery Mode”. At loft temperatures above 23°C the unit will switch itself automatically to “Standby Mode”. 2 At loft temperatures below 19°C the unit will operate on “Normal Operation Mode”. At loft temperatures above 18°C but less than 31°C, the unit will switch automatically to “Intelligent Heat Recovery Mode”. At loft temperatures above 30°C the unit will switch itself automatically to “Standby Mode”. 3 This option removes the temperature sensing function out of the unit. The unit will operate continuously in “Normal Operation Mode” depending on the volume control setting selected. 4 At loft temperatures below 16°C the unit will operate on “Normal Operation Mode”. At loft temperatures above 15°C but less than 28°C, the unit will switch automatically to “Heat Recovery Mode”. At loft temperatures above 27°C the unit will switch itself automatically to “Standby Mode”. 5 Not applicable for the HEAT model. What are the following modes, and how does the unit operate in those modes? “Normal Operation Mode” “Intelligent Heat Recovery Mode” “Heat Recovery Mode” (I assume this just has the word Intelligent missing? or is it a different mode?) “Standby Mode” Many Thanks, Dennis
Electrical Wiring Question
Hi, please can you tell me if this fan has: TWO connections (live/ neutral) or THREE connections (live/ switched live/ neutral) It's really important I know before I purchase it : ) Thank you
Can you make quite tight bends in it i.e. round a 90-degree corner, or does it need to be curved more gradually (resulting in bigger boxing-in)
Cyfan window kit
can this be installed in a double or triple glazed window?
Cut down doors?
We have put 'Envirovent' systems into a few properties and they recommend that the bottom of all doors are cut so that there is a 10mm gap at the bottom so that air can flow if doors are closed. Is this the same for the NUAIRE systems which I have only just discovered on the I-sells site
Can this be a constant trickle fan?
Hi, can this be used as a constant trickle extract fan, and boost with a light? thank you

Nuaire Ductmaster Thermal
Hi, I am looking at installing an MEV system in a renovation project. I would like to use a Vent-Axia Sentinel Multivent H and the Nuaire Ductmaster thermal system. Couple of questions about the Nuaire system: 1. Is it fully compatible with the Vent-Axia Sentinel? 2. Does the Nuaire system need to be clamped and supported at every join? 3. What is the outside diameter of the ducting - for external venting purposes? ie. what size hole do I need to drill? 4. Do standard 125mm extraction valves and stainless external vents fit the Nuaire system? 5. Is any condensation trap need on the exhaust run if it is going horizontally? Many thanks, Mike
Ceiling diffuser installation.
I have a double thickness ceiling to go through as it is old lath & plaster which was tacked over with plasterboard then plastered over. Will this cause a problem for me?
I can't adjust the slow speed and the high speed reostats so that the fan speeds up on turning on the switches to the bathrooms anymore. I can adjust to various speeds but it remains constant. It appears the control panel has failed. Can I get a replacement control panel. Thanks Nick
Trickle / Boost switch
when i bought vent unit from you in the kit was a trickle /boost switch. Even on trickle it seems extremely fast and on boost we are ready for take off. what can i do to reduce the speed further as ive talked with a qualified electrician and he considers it to be too high for "trickle" performance !!!!!!!!!!
Good morning. I need to fit some vents into a chimney stack that we are having to seal due to the fact that there is a cement/asbestos chimney liner running through the stack. Would these vents be suitable and how many would I need to fit to avoid damp forming in the disused stack?
I suffer from running condensation in our upstairs bedrooms. We have a small hallway on the first floor which accesses all bedrooms and then extends above the stairs. What is the optimum position for the unit. On the landing the ideal location is outside of the main bedroom door but I am worried of a slight draught being felt. The other option is on the ceiling above the bottom stair. Would the unit be as effective at this location? If so I wont be able to access the controls on the unit from the hallway so will choose the version with loft controls. I also note this is a basic version is the |HC version more efficient?
Hi there. I am considering purchasing the Drimaster Eco Heat Positive Input Ventilation Unit With Integral 400W Heater. I live in a single storey stone cottage which suffers from quite bad condensation. The Humidity levels are constantly around 70-80%. From the reviews of this product and your answers to any questions it would seem that this product may help. My cottage is quite long (around 25metres long) with a corridor running down half of it (the bedrooms are off the corridor) then into a large living and kitchen area (10m in length) which has a higher ceiling than the rest of the house. Please let me know if this is the unit that you would be recommending in this instance.

hi i have a narrow L-shape hallway which is 4ft wide.i wanted to fit diffuser a metre from front door,but ceiling has a roof beam right down middle of ceiling.as u turn right into second half of L-shape hallway there is a loft hatch then kitchen.i think i can fit diffuser just before lofthatch,as all doors are close by,is that ok?can u please tell me what will happen if diffuser is to near to near a wall,as i wanted to fit near front door as i have a rad which would mix the cold air,but one side of the diffuser would be near wall,so only other spot is near loft hatch. 1 last question,as unit draws air from loft gaps etc ,the soffit boards have been overclad with pvc and underneath is cement board which may or may not contain asbestos.if by chance the wind was to blow a fibre into the air would the filters stop it blowing into house.hope u can help regards
Hi, my bathroom extractor is fitted to a Screwfix vent - Manrose Cowl Vent Brown 100 x 100mm (14789) - but as it's NE facing it is still subject to rattling in the wind and is not doing what I want it to. Will your product minimise the wind noise? I prefer black as the colour.

Air flow in small rooms
Hi I have 2 clinical rooms (no noxious fumes ) that require ventilation and airflow for building regs. Sizes are 2.7 m X 3.4 and 2.3m X 3.4m. Would this unit move the air adequately for the 2 rooms if it was situated outside the room and would it be suggested to have ducts ending in a grill in the room? If not what would be the best option? Thanks

Do you have a installation service
Hi, Were looking at vents to go on side of the house that would be small enough that a mouse wouldn't get through. Would this product suffice?
What are the throat lengths on PVC ductwork?

Ducting and will this blow back cold
Hi, we have the drimaster eco hall control unit but still experiencing high humidity in the kitchen - standard about 77%. Will this help take out the kitchen humidity in conjunction with the drimaster? Ideally looking for this to go on the wall above the extractor fan? Anything else we need for example ducting?

Ventilation for a small flat
I live in a 50m2 basement apartment. It is a apartment with windows / doors facing the garden only. As there are no windows to the back, there is no adequate cross ventilation and therefore the apartment can become stuffy with stale air. The bathroom is also set to the rear. I am seeking a long-term ventilation solution / strategy that I presume will run 24 hours a day (silently) and then boost when moisture builds in the bathroom which is circa 7m2. I wish for the background ventilation unit to remove stale air. There needs to be a boost for bathroom ventilation / moisture control taking air in above the shower There is an existing ductwork route that runs to the roof of the ground level that I will use to expel air to outside. This route is about 10m. This unit will sit at the rear of the flat. Can you advise if this is a suitable product for me. Thank you very much. Theo
3 storey ventilation
Hi, I live in a 3 storey victorian property and have been looking at your PIV units. Is there any functional difference between the 3 storey unit and the standard units? The only difference I can see is the fire resistant ducting. Given the price difference between the standard and 3-storey versions and taking into account the cost of fire resistant ducting I was wondering if there was anything else? Thanks Owen
I need a form of ventilation when a straightening service is being done as it lets off a lot of steam and smells and makes our eyes water would this system be sufficient for my salon
Clicking noise from unit
Please can you give me an idea why the unit is making a continuous loud clicking noise. I have changed the filters but it still persists
I bought this fan as a replacement for our broken fan, but I can't get it to work. I've even tried plugging it into a socket but it won't work. The original fan was conected to our bathroom light. The wiring in the ceiling is 3 core black, grey and brown it is also wired through an fan isolator. In the isolater the grey wire is the neutral the brown is live 1 and the black is live 2. I've wired it as per the install wiring diagram but nothing works any help ?
How you know if the heater element is working? The air coming out feels as cold as outside. We've turned the up temperate up to max. I look forward to hearing from you.
My stairwell leads to a small landing (3 metres) one door to the left, one door to the right in a tee shape. It is one metre wide in every direction. Is it ok to put the vent at the top of stair well which is only 1 mtr wide just before it reaches the landing?
existing nuaire cyfan
hello, we had two fans fitted approximately 3 years ago. At the time I think there was a booklet regarding installation and adjustments, I cannot find this. Is it possible for you to provide a link, so I can download the details please. kind regards barry luxton, fairway construction.
Could you please advise me if this is stainless steel silver in colour or more of a dark chrome as it looks in the picture?
