Why switch from district heating to geothermal heating?

Turnkey geothermal heating solution
The traditional way to switch to geothermal is to apply for a loan from a bank and buy the system yourself. However, a building company can switch to geothermal heat 100% risk-free by buying geothermal heat as a service. Above all, buying as a service is hassle-free for the housing company. This means that
- Geonova finances the purchase of the system and provides the heat energy your housing company needs - and, if you wish, the cooling. Instead of a big initial investment, you pay a monthly fee.
- Geonova is responsible for the sizing, design, installation, maintenance and monitoring of the system throughout the contract period.
- After installation, Geonova will ensure and report that the system is operating at optimum efficiency and delivering the desired cost savings to the housing association.

Geothermal heating as a service - benefits for housing companies
When a housing company purchases geothermal energy as a service, it gains the benefits of geothermal energy without operational or financial risks.
Buying as a service is a smart solution for housing companies:
- no bank loans, no six-figure initial investment
- risk-free, as Geonova takes care of everything
- instead of geothermal energy, the housing company can invest in other essential projects
- significant cost savings during the contract period
- heating costs are easily budgeted for the long term
- the monthly fee includes system maintenance and optimization
- an annual report clearly shows the savings and emission reductions achieved by the housing company
- the option to purchase the system later on
Geothermal heating as a service can at best bring five-digit annual savingsfor a housing company
