Calculate Your Energy Savings with Confidence
Quickly estimate how switching to a heat pump can lower your energy bills.
Save on Energy Costs

Make Informed Decisions
Use this tool to compare options and choose the best energy upgrade for your needs and budget.
Calculate Your Potential Savings
Compare heat pumps versus conventional boilers to discover how much you can save on energy costs during the operational phase of your heat pump.
Important: This means that the purchase and installation of the heating systems are not included. Heat pump models vary in price and the cost of installation depends among other things on the heat source and possible renovations. Also, (government) funding might apply.
How to Calculate Savings
Use this calculator to estimate your savings by switching from gas or oil boilers to an efficient heat pump system.
Step One: Enter Your Data
Input your current fuel consumption to see potential savings tailored to your home.
You don’t know the heating energy consumption per square meter?
Either divide your total annual heating energy consumption by the area of your house/aparment OR just plug in the total annual value and change the heated area to 1.
You have an oil boiler instead of a gas boiler?
Take the current price of one liter (1 l) of heating oil and divide it by 10 for a rough estimate. Plug that number into the “Gas Price [Euro-Cent]” panel.
Example: 1 liter of heating oil = €0,9 = ct(€)90 | ct(€)90 / 10 = ct(€)9 | plug in 9 into “Gas Price [Euro-Cent]”
Step Two: Compare Costs
Review cost differences between your current system and a heat pump for informed decisions.
