suitability for subfloor damp
i have a stone cottage in cornwall - the drimaster seems perfect to reduce damp and condensation in the house. We have a subfloor - about 1m deep and ventilated poorly with airbricks - this is very damp. would the loft mounted drimaster also help in the subfloor or should i buy a second unit to suck air from the house and direct below the suspended wooden floor thanks ben

Air brick in bedroom/office
Hi I am writing to ask for some advice. I've recently bought a house that I am doing up. Many of the rooms have air bricks hidden behind the wallpaper. The house is approx 1930's and didn't have central heating until now. Do I need to retain the air bricks in the bedrooms upstairs? They appear to have remnants of white cavity wall insulation in them and have nothing lining the hole. If I do need to keep them, should I buy something like this to bridge the cavity? Is there a product that also helps reduce the noise passage whilst letting air flow? Thanks very much Gareth
Speed settings based upon clearance to walls.
Dear Sir/Madam, I purchased 2 units from for 2 different homes. However, I need help with the issue in the instructions that I have pasted below: "5.0 DIFFUSER INSTALLATION 5.1 Siting the Diffuser Position The diffuser has a unique air throw pattern and it is essential that it is located correctly in the central hallway in single storey properties or in the ceiling of the top floor landing on 2 or more storey dwellings. The diffuser discharges air evenly in all directions along the underside of the ceiling. Speed Setting Minimum distance of diffuser from wall 1 100mm 2 155mm 3 400mm 4 625mm 5 850mm 6 1000mm" I did not see these rules before my electrician installed the unit. However, he installed it with 200mm clearance to the walls in 2 directions, and over 1000mm clearance to the walls in 2 other directions. He then used the enclosed "air dams" to block off the 2 sides that had only 200mm clearance. My questions are: 1) Can I run my fan at speed 6 based upon the fact that the 2 sides from which the air flows have more than 1000mm clearance to the walls? 2) If not, what is the maximum speed setting that I can use on such a diffuser? 3) Is it advisable to leave the 2 sides with 200mm clearance blocked up or should all 4 sides be unblocked?

Where to position & recommended installer
We have black mould appearing in a flat that previously had no issues, although major works were carried out by the local authority and new tenants moved in at the same time. This is a maisonette and the problem is present in the bedrooms. Should we install this upstairs, as this is where the problem lies and can you please recommend a local installer for SW8 - what is the average cost to install? Many thanks
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

Cyfan window kit

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

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

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?
