The threats of climate change due to the excessive use of energy are increasing, the world and especially those countries that have a high energy use per capita must make maximum use of solar energy to lessen the threats.
UK Energy Use by Sector
Domestic energy accounts for almost 30% of total UK energy use, we can all do more to reduce this whenever solar heated air is available and required.
A large impact can be made by reducing our heating costs by using solar heated air which can reduce home heating costs by 10 to 20% and make your home more comfortable as it operates throughout the year.
Reducing our home thermostat setting by 2°C and wearing appropriate clothing can reduce your heating cost by 10%.
There are many other ways we can reduce our home energy consumption, see:
Energy Saving Trust, Energy Saving Quick Wins
Solar Air Heater Controller
When it is available, collecting, precisely controlling, monitoring and transferring free solar heated air into your home is by far the best and cheapest way to heat your home.
Home heating cost per kWh
In 2018 almost 30% of total annual UK energy is used for home heating.
Free Hot Solar Heated Air can be collected by solar air collectors, conservatories, and somewhat accidentally, home attics, then transferred into homes by fans at almost no cost.
Many solar air collectors and plans for them are available via the internet, the newly available Solar Air Heater Control is specifically designed for to suit a wide range of solar air heating systems using system configuration parameters.
The control not only efficiently controls solar heating systems, it also accurately measures and records solar heating system performance.
Home Heating system efficiency is calculated as Energy Out / Energy In.
Efficiencies are usually given either as a percentage, or as a 'COP' Coefficient Of Performance. Electric central heating has an efficiency of 1 (100%) as no energy is lost in the generation of heat. Typical solar air heating efficiencies range from 30 (3000%) to 80 (8000%)!
Home heating system efficiency translates into Heat Cost per kWh, the standard unit of energy. High efficiencies result in low costs, large cost savings for users, and they reduce fossil fuel use.
The heat energy provided by free solar heated air and transferred is proportional to the Hot – Cool air temperature difference, and to the air flow achieved. Typical annual average 'solar air collector – room temperature' differences achieved by our Solar Air Heater Control range from 4 to 10°C, this results in heating efficiencies from 30 to 208 when using fans similar to those specified above. The solar air heater control system operation is optimised to achieve a maximum average temperature difference.
The efficiency of a heating system is calculated from:
Heat Energy Produced / Heat Energy Used by the heating system
The heat energy used by a Solar Air Heating system is the power consumed by the fan plus
the power used by the control system, the Solar Air Heater Control is designed to consume negligible power.
