Voltan Energy

We are an energy company that focuses on heating and cooling solutions for buildings. We design, construct, finance, and operate geothermal heat pumps for large properties. We offer our services to developers, housing companies, real estate investors, municipalities and corporations.

As end users, the residents of the housing company / property owner only pay the bill for the energy used – without expensive system investments or complex construction projects.

Geothermal heat pumps offer a clean and cost-effective solution for heating buildings and enable cooling for the summer months.

Our management and advisory team have significant experience in construction, energy, and finance. We are backed by well-known Finnish industrial families and industry executives, with a vast experience in the construction industry and construction-related services.

By feeding one unit of energy into the geothermal system, 3–5 units of thermal energy can typically be transferred from the ground to the building. During summertime, the system also works in the other direction, i.e. it enables pleasant indoor cooling.

How it works

Geothermal heating is the most sustainable and cost-effective solution for heating and cooling buildings.

Locally generated heating and cooling energy relies on renewable energy sources such as sunlight or geothermal energy.

Geothermal heating facilities are always customized to best fit the needs of the housing company and the environment. The facilities are monitored and controlled remotely, ensuring an overall reliable operation and optimal heat production.

The benefits of geothermal energy come from technology that has been tested over a long time. It is proven to have a long lifespan and be extremely efficient: the input of one unit of energy typically provides 3–5 units of energy from the ground to the building.

The system works both ways: over the summer, the system produces pleasant cooling of the home.
