Heating method comparison service for properties

The heating method comparison service for properties provides the property owners or the boards of housing companies with an objective and clear heating method comparison report, a project plan, and an analysis and review of the results under the guidance of an expert. The service provides objective advice related to energy efficiency and the choice of a heating method.

Content of the report

  • Current form of heating, its costs and emissions
  • The estimated investment price, operating costs and emissions of the property’s other potential heating methods
  • The internal interest rates, current net value and repayment term, including the direct impact on housing charges, will be calculated separately for each potential investment
  • The operating cost history of the current heating method and forecasts for the different alternatives
  • Impacts of different options on maintenance charges based by apartment types
  • Preliminary drilling plan; we will review whether there is space on the plot to drill geothermal wells or whether there are possible obstacles to drilling
  • Sensitivity analysis of life-cycle costs
