HeatAdapt
Automate your heat pump based on hourly electricity prices
Built for air-to-water and ground source heat pumps

Designed for heat pumps
- Compatible with most air-to-water and ground source heat pumps
- Reduces electricity use during peak and high-cost hours
- Preheats during off-peak hours
- Produces hot water for the boiler during the lowest-cost hours
Timing your heating to off-peak hours can deliver significant savings
12% - 20% per year
saved by the smart module for our customers in 2023
up to 28% per month
reduced electricity costs in the months with the biggest savings, spring-autumn 2023
* Savings are based on a study of over ten Nordic buildings during the 2023/24 heating period, measuring energy consumption, room temperatures, and heat pump parameters to estimate electricity cost savings. Actual energy savings for a specific building may vary based on the building's characteristics, the heating system, occupant consumption habits, and fluctuations in power market prices.
Essential for anyone using a variable-rate energy plan
Enable automatic tracking of hourly electricity prices
HeatAdapt automatically schedules air-to-water and ground source heat pumps to consume electricity during lower-cost hours
Cost savings
Leverage low hourly electricity prices and decrease energy consumption during peak times, leading to substantial savings on your electricity bill.
Convenient
HeatAdapt automatically determines the most efficient heating pattern for each day by analysing hourly electricity prices, weather forecasts, and the building's thermal properties.
Environment
By automatically reducing energy use during peak hours, the load on the electricity grid is also reduced. This way, we can consume more green energy.
Likely the fastest return on investment for a heating system
HeatAdapt's management logic has been developed in a 12-month study in collaboration with TalTech researchers, involving detailed measurement, modelling and savings rate assessment of more than ten buildings.

Savings were modelled on more than ten small Nordic houses included in the study for the heating period 2023/24, measuring energy consumption, room temperatures and heat pump parameters, and estimating the average monthly savings in electricity costs. The annual savings are calculated on the basis of a 12-month average savings percentage. Actual energy savings for a particular building may be higher or lower due to the characteristics of the building and heating system, the consumption habits of the residents and fluctuations in hourly power market prices.
How does it work?

Smart control takes into account the dynamic electricity market price for each hour including network fees, the building's calculated heating demand, and the outdoor temperature, adjusting control based on the heat pump model. This ensures the maximum possible savings according to the hourly market prices for each day and the building's heating needs.
Web app provides a clear overview and control
Daily heating schedules are conveniently accessible on the web app. The graph also shows hourly electricity prices with network charges.
- Adjust settings for greater cost savings or enhanced comfort based on your preferences.
- Overview of hourly electricity prices and heating schedules
- Green bars indicate preheating, such as hot water production for the domestic hot water tank.
- During the red hours, heating is limited or restricted to avoid peak prices.

Good to know
HeatAdapt is specially designed for air-to-water and ground source heat pumps, making it ideal for homes with an hourly variable-rate electricity plan. Heat pumps typically account for 50-80% of annual electricity consumption in most homes, making smart heat pump management a key solution for significantly reducing electricity costs.
The module works by taking into account the hourly electricity price, grid tariff , and weather forecast. HeatAdapt selects the most efficient heating and hot water production patterns based on hourly prices for the day. This ensures heat pump consumption is scheduled during more favorable hours, minimizing the impact of peak prices.

To assess the savings for Nordic homes, the study examined more than ten buildings and modelled the average savings when using the HeatAdapt module. The results showed average savings of 12% to 20% per year on electricity costs based on 2023 electricity spot prices. Monthly savings varied due to fluctuations in electricity market prices, reaching up to 28% in some months.
Savings from the HeatAdapt module are specific to each building and will depend on the level of insulation in the building, the heating system as a whole, consumption patterns and future hourly electricity prices on the electricity market.
The study was carried out in cooperation with Estonian TalTech University throughout the 2023/24 heating season. During the course of the study, the behaviour of different heat pumps and buildings under HeatAdapt module management was measured in detail.
Each day HeatAdapt retrieves the hourly electricity market prices and takes into account the weather forecast, grid tariffs, and building and heating system characteristics. Based on this, an individual heating and hot water heating schedule, or heating pattern, is created for the heat pump.
Based on the heating pattern, HeatAdapt manages the heat pump throughout the day, reducing consumption during the most expensive hours and increasing power during cheaper hours.
To find the optimal heating pattern, the HeatAdapt team, in collaboration with TalTech, conducted a study during the 2023/24 heating period, measuring the behavior of more than ten Nordic homes with variable-rate electricity contracts.
HeatAdapt will increase the self-consumption of energy produced by solar panels.
For houses with solar panels, HeatAdapt considers the solar forecast along with the parameters of the solar installation and adjusts the heating pattern to maximize self-consumption.
HeatAdapt is compatible with devices from more than 20 manufacturers of air-to-water and ground source heat pumps.
For compatibility information, please consult your heat pump installer or specialist.
