Prices per kWh and heat sources in Sweden
Right now, there are many factors that coincide, which causes the price of electricity to rise to new heights. For example, there is a smaller amount of water in our reservoirs, a smaller share of nuclear power is produced, there are less winds than usual, raw material prices are higher than usual and, in addition, there are currently also higher prices for emission rights. According to forecasts, electricity use in the Nordic region will rise sharply in the next ten years, as a result of more data centers, electrification of industrial processes, more electric cars and population growth. The increased electricity use together with wiring expansion contributes to the sharply rising electricity prices.
We therefore see it as a necessity to heat our villas with sustainable bioenergy. Below you can fill in your electricity price, your heating needs and outside temperature to find out how different types of heating of your villa are affected by these factors. More information about pellet firing can be found under Heating with Pellets - Frequently asked questions.
COP values (Coefficient of Performance)
Also often called the heat factor or efficiency. The COP value is a comparison between how much power the heat pump gives, against the power that the heat pump consumes. A COP value of 3 thus means that the heat pump provides 3 times as much energy as it consumes.
Air-water heat pumps
Air-water heat pumps are classified based on + 35 ° C in the supply line and + 7 ° C outdoors. This is of course not realistic if you do not have a newly built house with underfloor heating, and when you actually have a greater need for heating.
Our calculator is therefore based on the COP values below, taken from the Swedish Energy Agency, where you can choose a realistic supply and outdoor temperature.
|Outer temperature||COP-value (Coefficient of Performance)|
Geothermal heat pumps
Geothermal heat pumps use the groundwater that is stored in the bedrock and which maintains a temperature of around 7 degrees all year round. Therefore, only the flow temperature is taken into account in our calculator. Given the enormously high investment and maintenance costs, combined with the need for a higher supply temperature if the house is not newly built, geothermal heating is a very expensive alternative.
