SolarVenti's new report shows that a single SV30 generates up to 2kW per hour of free energy, even in external temperatures below the annual UK average of 14 Celsius. During daylight hours, a SolarVenti SV30 will warm incoming air to between 30 and 40 Celsius higher than the outside temperature.
SolarVenti says that customers can significantly cut their heating costs and carbon footprint by using this free energy to heat internal spaces, or to heat water, with an average energy output in full sunlight of more than 1.5kW per hour.
The report also highlighted the unit's dehumidification capability. During daylight hours, the average relative humidity of incoming air was reduced by 80% compared with ambient. This further reduces heating bills, as heating a dry home requires less energy than heating a damp, humid property.
According to Bob Goodwin, director of SolarVenti UK, "This real-world testing of the SolarVenti units' capabilities shows just how much free energy people can gain – and how much they can save over a year, with gas and electricity costs being so high. The units are fit-and-forget, enabling home owners to slash their energy costs and extend the life of their property."
The SolarVenti units are powered by a highly efficient solar cell, so they consume no energy and give no harmful emissions. In sunlight, the units activate to provide interior space heating by warming large volumes of incoming air. This also safely dehumidifies all types of property that may suffer from airborne damp by displacing and replacing the damp air with warmed dry air.
As the UK has an average of 1400 hours of sunlight per year, SolarVenti units work all year round with no environmental impact, delivering internal heating and hot water in homes, holiday cottages and living spaces without using electricity, chemicals or refrigerants – reducing utility bills and lowering carbon emissions.
The SV30, which provides heated airflow of up to 150 cubic metres per hour heats incoming air by up to 40 Celsius above the external ambient temperature, costs £1272 +VAT including wall mounting brackets and fittings. Roof mounting kits are also available for all larger SolarVenti units.
The SV30H Plus model heats both Air and Water in one unit. This gives heated airflow of up to 100 cubic metres per hour and heating incoming air by up to 40 Celsius above ambient. It also produces hot water at temperatures up to 55 - 65 Celsius and is supplied as a complete self-install package including hot water cylinder, heat exchanger, solar-powered pump, pipework and fittings, at £2532 + VAT. The unit can be switched between heating the air or water or a mix of both. Airflow from SolarVenti units is controlled with the supplied regulator. Thermostats are also supplied with all SV30 models.
The SolarVenti units' air heating and dehumidification capabilities make them suitable for any property that would benefit from dry, warmed air circulation, such as storage facilities and all types of public and commercial property. The units also help prevent problems of damp while properties are unoccupied, extending the life and cutting the running costs of all types of property or living space.
