Heat Pumps

Heat pumps connect the electrical and thermal energy systems and increase flexibility in heat production from sustainable sources.

Heat Pumps utilise fluctuating renewable sources in the thermal grid
Large heat pumps used in district heating plants help integrate excess renewable power into the thermal energy system. Electricity is difficult to store, so heat pumps should be used for thermal purses, when production of electricity is abundant. Other sources of energy for thermal energy production, such as biomass and waste, are easier to store and can therefore be saved to times when less electricity is available and the electricity prices are high. By installing large heat pumps, the district heating plants help balance the electrical energy system.

Heat Pumps outside the thermal grid
Buildings outside the thermal grid can also benefit from heat pumps. Small heat pumps can be used for individual buildings and larger pumps can supply heat to closely located buildings. By using heat pumps instead of other individual heating options, local air-pollution is avoided and the quality of life is improved. Moreover, heat pumps can be integrated with Heat Recovery and Ventilation creating an improved indoor climate.

Denmark increases the use of Heat Pumps
In Denmark, the use of heat pumps will increase in the coming years. In district heating, which covers 50 % of the Danish heat demand, heat pumps are increasingly used. This enables higher levels of wind energy to be used for thermal purposes, which contributes to the goal of 100% district heating to derive from renewable sources by 2035.
