We also have a thermal imaging camera that we use to detect leaks, energy losses in houses or to locate pipes in buildings.

Air-to-water heat pump ELCO

Heating renovation from oil to air-to-water heat pump.

There are also high-temperature air-to-water heat pumps up to 75°C. These can be used to heat practically all houses without any loss of comfort or increase in heating surface area. However, high-temperature heat pumps are not particularly efficient. Such machines are available for indoor and outdoor installation.
In principle, however, you should first check the thermal insulation and windows for improvements and only then have the heating system determined.
