2024 was the planet’s warmest year on record: Even though Finland is known for its cold climate, also we broke a record. The temperature was above +30 degrees somewhere in Finland for 3 weeks in a row. Hot summers are boosting the cooling demand: Fortunately, we can offer an economical and environmentally friendly solution.
Geothermal wells (boreholes) contain geothermal heat that is usually around 4–7 C in Finland. This renewable energy source is thus also a very cost-effective source for cooling – and comes with no worries regarding the carbon footprint. For residents in the building, the use of a smart geothermal cooling unit is almost free: The electricity use is equal to ca. 3 LED lamps, i.e. the electricity cost is around 1/20 of an air-source heat pump.
Geothermal cooling is an environmentally friendly choice as such – and geothermal heating & cooling are 100% CO2-free, if the property uses electricity from renewable sources. This has a major impact on the carbon footprint, because district heating is still the biggest source for greenhouse emissions by far. – Even after a notable cuts, it still generated e.g. 46% of CO2 emissions in Helsinki 2024.
Geothermal cooling has a number of benefits: The same equipment that is needed for geothermal heating also works for cooling. And in newer buildings, the original supply air pipeline network and equipment in apartments / flats can be used for cooling, too. This typically cuts the cooling system investment in apartment houses by 33%.
When Smart Heating builds the hybrid heating system with geothermal heating and cooling, we deliver a turnkey project and take care of the maintenance during the system lifecycle. In addition, the Smart Heating hybrid system comes with a 5-year full warranty, and the heat production efficiency and capacity are guaranteed for the whole heating / cooling system lifecycle. Geothermal cooling is therefore a carefree and reliable cooling system, when the Smart Heating automation is monitoring e.g. the room temperature and humidity 24/7.
