Geothermal Solutions
What is geothermal energy?
it’s energy created by the sun and stored in the earth
The temperature underground is constant between 5°C and 10°C
warmer than the air in the winter and cooler than the air in the summer
Geothermal energy is captured using a:
Ground Source Heat Pumps
Geothermal exchange Systems
Geothermal Systems
What is geothermal energy?
The length of the loops is determined by the amount of energy needed
i.e. the size of the building and its heating and cooling requirements
The building envelope (air sealing, insulation and fresh air make up) is critical to sizing the system correctly
water and ethanol refrigerant (grain alcohol) circulate through the loops
Residential Geothermal Market
33,000 systems installed in Canada, 25% - 40% are in Ontario
1.5 million Ontario households use fuel other than natural gas for heating - geothermal is replacing those systems
Central air conditioning is now standard in new homes increasing electricity consumption per household - geothermal provides cooling using less electricity
