Recent research and product development into renewable energy use for home heating has resulted in new ultra-efficient Automatic Solar Home Space Heating Systems.
Solar Space Heating Systems are an effective and excellent way to reduce costly energy bills during your heating season. Solar Space Heaters work alongside home heating systems using the sun's energy to heat your home reducing your consumption of electricity, oil, propane, or other fossil fuels.
Why use Solar Space Heating systems? - because they are:
The most efficient home heating system available
10 to 100 times less expensive to run than your current heating system
Use a renewable energy source
Inexpensive to buy and easy to install
Very reliable, and need little if any maintenance
Conservatory Heat Harvesting Systems increase conservatory comfort levels
Attics and conservatories can capture many 100's of kWh's of free heat from the sun. Our Solar Space Heating system is an ultra-efficient new secondary home heating system that transfers this free heat into homes reducing the use of far more expensive alternative heating systems.
Of course solar space heating is dependent on solar heat, which is not always available, but you may be surprised at how much solar energy is collected and stored in parts of your home at all times of the year even on partly cloudy days. Because solar heat harvester systems have such low installation and running costs it is a very valid secondary home heat source which will considerably reduce home heating costs.
This website has many pages, two describe detailed case studies showing Attic and Conservatory Solar Space Heating Systems (CSSH) performance.
In October 2017 the UK average annual home space heating costs and use in a 3
bedroom semi-detached home obtained from which.co.uk are shown in the first two
columns in the table below. The third column is calculated by dividing the first column
value by the second giving the heat cost per kWh.
|Home Space Heating Costs
Data from Which.co.uk
|Oil fuelled central heating||£454||12,500||£0.036|
|Ground source heat pump||£460||12,500||£0.037|
|Air source heat pump||£500||12,500||£0.040|
|Gas fuelled central heating||£609||13,500||£0.045|
|LPG fuelled central heating||£809||12,500||£0.065|
|Electric central heating||£2053||13,500||£0.152|
The first histogram below shows 2017 average annual space heating costs for semi-detached
3 bedroom home.
In 2017 the average annual Home Space Heating Costs ranged from £454 to £2,053.

Two types of Solar Space Heating system have been researched, developed and tested during the last seven years. Attic Solar Space Heating Systems (ASSH) transfer solar heated attic air, or heat from the home that has warmed the attic (heat recovery) into and through the home, Conservatory Solar Space Heating Systems (CSSH) transfer free solar heated conservatory air from it's apex into and through the home.
Both our attic and conservatory solar space heating systems can use new energy saving motors which increase the system efficiency as shown in the home heating efficiency charts below. As both systems move heat around the home, home humidity levels are reduced decreasing moisture and condensation. In attic heat harvesting applications, in cool periods of the year, the system can efficiently recover heat from the home heating system that escapes into the attic transferring it back into the home.
If during periods of the year your home has rooms that need heating when other areas get hot due to renewable solar heat from the sun, our Automatic Solar Space Heating system can transfer the free solar heat into and through your home at little to no cost. Attic Solar Space Heating systems have many advantages, one is that it reduces the operating time and hence maintenance cost of your current home heating system potentially saving many £10's or £100's on your fuel bills every year and reduces your carbon footprint.
Home attics, especially those with slate or vinyl tiled roofs, and conservatories, can get surprisingly hot (35°c to 50°c), even on partly cloudy days.
If you don't know how hot the air at a high point in your attic or conservatory gets, you can check it by buying an inexpensive wireless remote temperature monitor, some record maximum and minimum temperature and humidity. The ThermoPro TP60 is supplied with a remote temperature monitor.
An alternative temperature and humidity monitor is the Elitech RC-5 Data USB temperature monitor. This records temperature every 'user preset' period that can be downloaded to Microsoft Excel.
Conservatory Solar Space Heating Systems and Attic Solar Space Heating Systems, the most efficient home heating system available?
The impact of an Attic Solar Space Heating systems on home temperatures is shown in the next chart.
The chart shows temperatures in a scottish home, both without (17,18 July) and with (19 to 23 July) one of our Attic Solar Space Heating systems operating.
When the attic temperature (red line) exceeds the room temperature (green line), shown by areas H, it indicates that Attic Solar Space Heating is very practical.
The blue line shows outdoor temperatures, the dotted blue line average outdoor temperatures. The impact of using heat from the attic is shown initially on July 19. The room temperature begins to rise when the system fan/blower is turned on by the custom controller. The rate of rise in attic temperature slows as the blower is running until the room temperature reaches the maximum user preset temperature, 23°c, when the blower is turned off. The attic temperature then rises rapidly as shown in the chart.
Temperatures were measured and recorded using a data logger. When operating, the average room temperature, shown by the green dashed line, increased initially by 3°c then by 4°c. The total operating cost of the system for four days was £0.27, and for the year £4.51 when 598 kWh were harvested.
The extraordinary low heat cost per kWh from our Solar Space Heating systems results because the heat is free and, in contrast to ground and air source heat pumps, the cost of transferring the heat to the home is almost negligible. Pages in this website detail the theory behind the system, what it is and how well it works.
The future of our planet and mankind's descendants is in our hands, the lifestyles most of us lead are destroying Mother Earth. Just one aspect of this is the rate at which we are consuming fossil fuels, it took 60 billion years of the suns energy to produce them, we are currently burning them in decades.
Earths inhabitants must dramatically reduce their energy consumption wherever possible by switching to renewable energy. One way to do this is to make the most of solar heat to heat our homes.
