The "warm loans" program provides for improving energy efficiency of the households. The state reimburses program participants 20-35% of the cost of goods bought on credit. The energy efficiency measures include insulation of buildings, installation of water and heat meters, heaters with thermostatic regulators, replacement of windows, modernization of lighting and other things.
The scope of the program was expanded in 2017, going from including only households connected to district heating networks to also including households with autonomous heating systems.
In 2020, the program's scope was extended again to include charging equipment for electric vehicles.
