This case study is highlighting the positive impact of eco2heat® infrared heaters on a 140 square meter house in Eslöv, southern Sweden. The old air heat pump in the house was replaced with 8x eco2heat® infrared heaters in October 2022, which included eco2heat® in-built heaters inside the walls. The total output of the new heaters was 3,700 watts.
Data was collected from October 2022 to March 2023, over a period of 155 days, where a smart home system to control the thermostat and measure energy consumption. This enabled a side-by-side comparison of the energy consumption before and after the installation of the new heaters. The comparison showed a significant improvement in energy efficiency, with the new heaters consuming 22% less energy than the old air heat pump.
Additionally, the owner noticed a significant improvement in the indoor climate, as the eco2heat® infrared heaters created a cozy and space-saving environment.
Data:
| Year of construction | 2003 (well insulated) |
| Living area | 140 m² |
| Average heating period per year | 210 days |
| Average operating time in hours | 8 hours |
| Average room temperature | 19 - 20,5 °C (IR feels 2°C warmer) |
| New Heating System | 8x eco2heat® heaters (max output 3700 Watt) |
| Thermostat control | Smart Home with energy measuring |
Comparison:
| Heatpump | eco2heat® | |
| Heating period | 2021/22 (155 days) | 2021/22 (155 days) |
| Average outside temperature | 5 °C | 4,4 °C |
| Heat Demand | 32 Watt / m² |
25 Watt / m² |
| kWh Consumption | 5537 kWh | 4350 kWh |
| kWh per Day | 36 kWh | 28 kWh |
Result:
- Heat demand of 25 watts per m² with eco2heat®
- Approximately 1200 kWh savings during the comparison period
- Approximately 22% energy savings compared to the heat pump
