Voltan Energy

We are an energy company that focuses on residential heating and cooling solutions. We design, construct, finance, and operate ground-source heat pumps for large residential properties. We offer our services to developers and real estate investors.

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

Ground-source heat pumps offer a clean and cost-effective solution for heating residential buildings and enabling summer cooling.

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

Ground-source heating is the most sustainable and cost-effective solution for heating and cooling residential buildings.

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

Ground-source heating facilities are always customized to best fit the needs of the housing association 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.
