The glycol is further compressed with the help of other pumps, which raises its temperature, and is fed into the heating system. In the experiment, an old naval barracks with an area of 140 square metres was heated to a comfortable temperature of 25 °C with the help of one 13 kW pump and 12 radiators. The building was not fully insulated. An important point – the testers managed to get four times more thermal energy than was spent in the form of electricity for the compression of glycol.

Now the authors of the development are preparing a project for year-round heating of the local museum complex using heat from nearby reservoirs. They have no illusions that they will be able to completely abandon the use of other energy sources. However, they hope to reduce heating costs by at least 75 per cent.
