Reducing Your Running Costs
Reduce the running costs of your heating using these below tips
-
Adequate Insulation
Ensure adequate insulation.
-
System Zoning
Zone the system into rooms such as kitchen, lounge, hallway and WC. This will allow independent control of these areas in which areas may be used more frequently than others.
-
Thermostat Programming
Thermostat programming is an essential step when using your infrared heating system. Having the system scheduled to run at higher temps at key points within the day and lower temperatures when the room is not being used can save on the pocket.
This calculator provides estimates based on typical infrared heating performance. Actual costs may vary depending on insulation, usage patterns, and local energy rates. Solar generation assumes UK average of 2.7 kWh/kWp/day with 50% alignment ratio. Battery efficiency assumes 90% round-trip efficiency. Consult with an energy professional for precise calculations.
