Case Study 02

Here's exactly how this pharmacy saved £1,347.84 a year on their over-door heating bill using a single infrared heater.

In this example, we had an over-door heater in the inside of a pharmacy.

The door is a standard sized double door, and had a 3kW Convection Fan Heater installed over it. Given that the heater is on for the entirety of the 8 hours per day that the pharmacy is open for, calculating the yearly energy consumption is relatively straightforward.

The pharmacy switched over to a Mirrorstone 1200w Helios Bar Heater. Below are the differences in power consumption for the year.

Model Yearly Consumption
3kW Convection Fan Heater 6240kWh
Mirrorstone 1200w Helios Bar Heater 2496kWh

The difference in power consumption for the year is already apparent, but when we apply the maximum cost of electricity, 36p per kWh, we end up with the following costs.

Model Yearly Consumption
3kW Convection Fan Heater £2,246.40
Mirrorstone 1200w Helios Bar Heater £898.56

By switching to electric infrared, the pharmacy saved exactly 60% on the cost of their over door heater! This equates to an actual monetary saving of £1,347.84 annually.
