HEAT PUMPS
A heat pump uses heat stored in the environment for space heating and domestic hot water. MELKERLITA selects a heat pump according to the building’s heat demand, the existing or planned heating system and the technical conditions of the property.

Heat pumps differ in their heat source, installation requirements and operating characteristics. The most suitable solution depends on the building, site and planned investment.
Heat is taken from the outdoor air and transferred to the building’s hydronic heating system. This solution does not require geothermal boreholes or a horizontal ground collector.
Benefit: simpler heat-source installation.
Important considerations: efficiency at low outdoor temperatures, outdoor-unit placement, noise and defrost cycles.
Heat is collected from the ground using a vertical or horizontal collector and transferred to the heat pump.
Benefit: comparatively stable heat-source temperatures.
Important considerations: site area, ground conditions, collector size and installation work.
Groundwater is used as the heat source, and its heat is transferred to the heat pump through a heat exchanger.
Benefit: high system efficiency may be achieved under suitable conditions.
Important considerations: water yield and quality, hydrogeological conditions, water return and permits.
A heat pump uses heat available in the environment and, with electrical energy, raises its temperature to the level required for heating the building.
A correctly selected heat pump must match the calculated heat demand of the building and operate in balance with the heating and domestic hot water system. Undersized or oversized equipment, an unsuitable temperature regime or unassessed site conditions can affect comfort and operating costs.
Heat pump installation cost depends on the selected technology, building heat demand, equipment specifications and scope of installation work. For geothermal systems, the cost of boreholes or the ground collector is also important.
A final estimate is prepared after assessing the specific property.
