Great potential for reduced energy use

A new comprehensive study shows that installing heat pumps can reduce households' total energy use by an average of 40 percent. Researchers analyzed data from over 1,300 households that switched to heat pumps and found that electricity consumption increased by 61 percent while gas consumption decreased by 90 percent.

The net effect was a total reduction in energy use of 40 percent, which corresponds to 6,120 kilowatt-hours per year for an average household. This is a significantly larger saving than what has been shown in previous studies of energy efficiency measures.

The heat pumps also led to reduced carbon dioxide emissions. During the first year, emissions decreased by 36 percent or 1.16 tons of carbon dioxide per household.

Time-of-use electricity tariffs provide additional benefits

The study also examined the effects of a special electricity tariff adapted for heat pump owners, called Cosy. This tariff provided lower prices during off-peak hours and higher prices during peak hours. The results showed that households more than doubled their electricity consumption during off-peak hours and halved it during peak hours.

Even electric vehicle owners adapted their charging to off-peak hours after switching to the Cosy tariff.

The results show that there is great flexibility in household energy use that can be utilized with the right incentives. This is promising for the future energy system with a high proportion of renewable electricity.
