Heating building versus heating car
When you get into your car after the sun has been shining on it, can there be anyone who has not felt the energy that has been captured from the sun by the car for free? SolarVenti captures that same free solar warmed air energy and pumps it into your house using only solar power so that the running cost is nil. The positioning of the SolarVenti is designed to make very effective use of available winter sunshine. See also space heating for more info.
So can I really save energy with SolarVenti?
Without doubt, and by a greater level than you may initially think. As well as keeping the humidity levels in your property low, and providing a substantial amount of fresh air ventilation, the larger SolarVenti units also provide a surprising amount of supplementary space heating for your property.
How can the larger SolarVenti units save on energy?
Let's take a look at the energy outputs of our larger units.
The SV14 outputs ~0.6 Kilowatts of energy per hour each hour the sun shines. We get an average of 1600+ hours of sunshine each year in the UK. If we assume that only 1000 of these hours are usable (you do not want very warm air input into your property in high summer when it is already hot), then even the SV14 can provide up to 600 Kilowatts of free space heating energy annually.
For the SV30, the equivalent figures are:- Output is ~1.6 Kilowatts per hour - this equates to up to 1600 Kilowatt-Hours of free space heating energy annually. (The SV30AWX produces ~1.3Kilowatts per hour).
So what does that mean in terms of my overall energy consumption?
Depending on which figures you believe are correct for the average UK household energy consumption, these outputs have quite an impact on overall energy consumption. The figures for average household energy consumption vary from 3,300 Kilowatts to 4,900 Kilowatts per annum. Of course, there are many different sizes and types of property, with varying levels of heating efficiency and insulation etc., so these figures can not be considered to be anything other than indicative maxima.
SV14: 1000 Hrs @ 0.6 Kw = 600 Kw = 18% of 3,300 Kw or 12% of 4900 Kw
SV30: 1000 Hrs @ 1.6 Kw = 1600 Kw = 48% of 3,300 Kw or 32% of 4900 Kw
So the larger SolarVenti units can provide a significant proportion of your overall energy for free, thus saving on your costs for space heating.
Dry air versus damp air in buildings
Additionally, SolarVenti reduces your main space heating energy consumption in another important way. It requires much less energy to heat dry air than it does to heat air laden with moisture. SolarVenti displaces and expels dampness from buildings and because the air inside a property is then much drier because of the SolarVenti, so less energy is required to heat it.
Are there any examples of actual savings made by the installation of a SolarVenti unit?
The very first SV30 users in the UK are reporting a significant reduction in their heating bills.
You can read their feedback comments for details of their assessment.
More recently a closely monitored SV30 installation installed in Victoria Australia (similar climate to UK) reports energy savings of almost 35% over the winter quarter. Technical Data for this assessment is available by request.

There are six products in the SolarVenti range. Under ideal sunny conditions the smallest unit, the SV2 has a minimum airflow of 20m³/Hour whilst the largest, the SV30 unit has a minimum airflow of 120m³/Hour.
The most recent product is the SV30AWX, a hybrid version of the SV30 which additionally provides Solar Water Heating.
Coming in early 2013 will be the SV20: a product designed to fill in the gap between the SV14 and SV30 models. |
