Experience shows that, this way, the heating consumption can be reduced by between 15 and 25% with an investment, which is typically paid back in less than one year.
One of the local authorities is the Sønderborg municipality which made an EnergyTrim™ agreement with Danfoss in August 2009. Under the agreement, the municipality’s heating system is reviewed and optimised over the next three years.
So far, 70 of the municipality’s geriatric care facilities, primary and lower secondary schools and day care facilities are covered by the agreement and they expect to save a total of more than 1m DKK annually on the heating bill.
The agreements with the municipalities include Danfoss’ EnergyTrim™ concept meaning that Danfoss’ technicians review the heating and tap water systems, adjust the systems for optimum use and point out any defect or worn down components.
The technicians return several times each year to trim the heating systems and, thereby, they make sure that the energy consumption continuously decreases.
