8. Since fitted I have been delighted. I had constant issues with condensation, really cold rooms at one end of the house, and that constant feeling when you took clothes out of the wardrobes or drawers that they felt wet. These issues are all gone. I used to have the small radiators in some rooms to take the chill of but they are now in the garage. The house just feels nicer.
I am guessing no one was home because the internal temp was left at 89 until 5pm. Note how the aircons cooling curve is also beautifully bent. Its a leaky bucket curve too.
You say some things that are huh?
This isnt coming from the roof as the temp is lower and falling and it isnt coming from the ambient outside as it is falling too.
I am sorry but while the conclusion is correct the reason cant be let stand as it will only mess you up to believe that, the direction of its change is irrelevant. perhaps the roof temp is falling because its heat is going inside?.
Even without bypassing the thermostat you can decrease your risk by operating an electric space heater with the thermostat always turned to the maximum position. This will result in the least switching and prolong the life of the thermostat contacts. Often the on/off switch has a few positions (off, low, med, high). It 8767 s safest to use this switch to regulate the heat output and leave the thermostat knob set to maximum.
No worries. Am glad you found the solutions that work for your house. Am not sure what I dislike more: an average company with a bad product (ventis) or a bad company with average products (apple).
However you do not necessarily need a large roof space for this to work. Warm air rises, so when the sun shines on the roof, the war air that is rising is the air that's directly under the roof material (tiles or colorbond for example) and so the air isn't taken from the bottom of the roof space &ndash where the ceiling is. so the warm air moves up the inner surface of the roofing material, and therefore the surface area is the most important. Not the volume of air. This has been proven time and time again through our experience installing into both spaces. I agree, logic will tell you that volume would be better. however experience has demonstrated otherwise. Hope that helps.
I have been in my roof space.
The top of the ceiling is indeed filthy.
I have been in a long abandoned house the floor was filthy.
If air is relatively still the dust falls out. if nothing disturbs it on the floor it builds up.
Our house is 9 years old, ~76sq. rectangular in shape with a Northerly aspect. The living rooms are situated to the east of the house and the bedrooms in the west. The house has high ceilings throughout. Currently, the house uses a reverse cycle aircon unit, which we have found to cope adequately for the temperature ranges we routinely encounter in CBR. All internal exhaust systems, toilets, bathrooms and kitchen vent to the outside outside
Congrats for this article, it is VERY interesting indeed. I found it looking for some information on the internet about the heating market in Canada.
I write from Europe and I work in a company that manufactures low consumption, highly efficient electric heating systems (radiators, towel rails and unvented water heaters). We are developing the products to enter the market of North America and I believe your conclusions in this article are very good.
Electronic Commutation. EC is not a new concept, but it has not long been available for domestic type applications (only a few years). To the best of our knowledge, Ventis is the ONLY home ventilation company using this EC fan technology.
It is not necessary to double glaze the whole house to get some benefit from it. $9-$5k spent on double glazing on a window, or two, particularly in a room that is heated and/or cooled the most (living space?) may reduce energy bills and provide more comfort than if that amount was spent on a Ventis.
So during winter here in Canberra, the outside temp is say, 8 deg. The temp in my roof is say 67deg. The temp inside is 69-75 deg with my gas heater on. How would pumping 67 deg air from my roof cavity heat my house?
.exactly my problem. I still like the idea, but can't see what any payback would be without just taking the plunge. Which I'm not inclined to do yet whilst there's such wildly conflicting views.
I'm also interested in trying to reduce my energy costs &ndash I have Solar hot water and about 8KW of solar panels on the roof. I see the benefits of these things immediately by the quarterly power bills.
my argument is that physics says that the difference in the amount of energy required to heat a humid room compared to a dry room is negligible. This would mean that in a controlled test if you took two identical rooms, one filled with humid air and one filled with dry air, put a thermometer in each and then measured how much energy it took to raise them both from the same starting temperature to a higher temperature, then the difference in energy should be minimal (ie. the 6-7% I suggested previously).
