UniBond 1807937 Aero-360 Pure Moisture Absorber Device

we have night storage heaters 'new model fitted this year' that come on straight away and heat the house all thro the night and day, get cool about 10.30pm at night.

have double glazing fitted, vents open all the time on windows and dont dry clothes in the house, but get loads of condensation on the windows all the time

looking at the above as its a cheap option, but if the below would do a better job would consider that as we are fed up mopping up windows and sills. any advice please

The first one is a joke - don't expect it to be effective in any space bigger than a rather small cupboard.

The second is quite different - I have two of the same machine under a different brand and they have made a huge positive difference to my house, health and electricity bill in the last year.

I am totally new to this topic and this device.

Am I correct in saying that with this machine plugged in , the condensation on the windows would stop ? And the laundry would dry soon ?

Do you have to buy one for each room ?

A dehumidifier will make a difference to the amount of moisture in the air so yes it should reduce the amount of condensation on your windows. However unless you leave it running all night, all the warm moist air you breathe out when asleep will still form as condensation on the windows.

I read a lot about the dessicant type (like the Ecoair) being very good at what they do however a large proportion seem to fail after a year or so, so I bought a traditional refridgerant dehumidifier instead.

Dehumidifiers are expensive to run... Get a Nuaire Drimaster... check out the reviews on amazon. Ive just had one fitted and its resolved all damp issues in my house...

Heres my review of the product...

I work in facilties management and HVAC for commercial buildings so I am used to dealing with large air handling units for office buildings and other complexes. I am aware therefore of how buildings have to provide fresh air for occupants. This is a simplified miniature version for the home. I bought the version with the heater option as it was cheaper to have it built in rather than buy it at a later stage. My main reason for purchase was for ventilation and fresh air because I live next the motorway so lots of noise and dust from traffic etc. I love fresh air also so my windows are constantly on the catch all the time but this means cold air just infiltrates the house but doesn't really ventilate. I don't have any damp issues other than the bathroom walls dripping with water after a shower. My house is a 2 bed small end terrace with 2 rooms down and 3 rooms up double glazing no trickle vents, cavity wall insulation and above the recommended loft insulation.

I had issues with cooking smells lingering and getting upstairs along with bathroom smells coming downstairs and the usual stale bedrooms on a morning, despite windows being left on the catch 24/7 it made no difference. The fan was installed by an electrician with the vent put into my landing ceiling. It was recommended for the size of my house that speed setting 2/3 was used but I couldn't feel much air flow from the vent. As I wanted to actually feel fresh air coming into the house the same way an open window I put it onto speed setting 4. I closed all the windows so the house is only relying on the Drimaster fan to ventilate and within half an hour the landing felt and smelt fresher with clean filtered cooler air coming in. My lodgers were cooking burgers and frying them in the pan that evening (I hate frying smells) and usually you can still smell this through the house the next morning especially the kitchen. Now the next morning there were no cooking smells at all, nothing unpleasant just fresh and aired. The house even felt warmer. Our kitchen is also feeling warmer and this is the coldest room in the house as there are cold draughts coming under the cabinets and around appliances.

What the fan does is filter air from the loft & pump it into the house from a central point (landing) which then pressurises the house. This is the same as what they do in operating theatres to ensure there is no dirty air penetrating into the theatre environment. Imagine a balloon with holes in it and your trying to keep it blown up. The balloon is the structure of the house and the holes represent the air gaps within the house such as cracks around doors under floors and air bricks that sort of thing. Normally outside air will penetrate these gaps which results in a cold house and that's how your house normally ventilates but inefficiently so. The fan is technically blowing the house up keeping a gentle pressure that is higher than outside so any stale damp air is pushed out through the gaps inside-outside. This means that the cold air that was coming in round cupboards and skirting boards in the kitchen are kept at bay. Any smells and humidity are constantly diluted down with the filtered, clean, fresh & dry air.

I'm amazed at how good the fan is at circulating the air. This is not a propeller fan like you would have on your desk (which would do nothing) it is a Centrifugal fan which are used to push air and create pressure in a space. If its 12C outside the temperature of my loft is 16C, I fitted a digital thermometer in the loft and one outside to compare... so instead of 12C dirty polluted air coming in through the windows I now have 16C air blowing into the house. Should the loft drop below 10c the small 500w heater will kick in and pulse on and off to increase the air temp upto 8C this is just for comfort of the occupants so you dont feel icy cold air circulating on the landing and its there as an option should I decide to fit it on a timer so that the heater part only runs on a morning when people are getting ready or on an evening. We had a cold night last week where it was 4C outside and the loft was at 8c so the heater kicked in and the air blowing out was at 16C on the landing.

Yes it makes your landing a little cooler but if you want a fresh and dry home then there has to be compromise and nothing is free but this is the best and most efficient way of achieving it without expensive dehumidifiers. Even if your heating is on a bit longer this still no where near like the running costs of a dehumidifier which don't really help and cost a lot to run. Nothing can beat fresh filtered air and plus the air flow from it is warmer than it would be opening a window due to the loft being 4/5c above the outdoor temperature. You might as well reuse that heat that has escaped into the loft as even if you have the best possible insulation heat will still escape.

Hope this review helps people, don't hesitate in getting one I wish I had got one sooner. The house is less draughty especially on the landing & stairs where you could feel the cold air from the windows on the catches just sinking down the stairs. Anyone that has had poor luck with these you either need to adjust the fan speed higher or lower. If its too draughty turn the fan down or turn up if you are not getting the results you were expecting. Keep all windows closed as air will take the easiest route out of the house and that will be the windows. Leave internal doors ajar.

Any questions please ask
