Today, the fifth issue of our ‘Infrared radiant heaters for your patio’ Trotec guide is all about money. Because if you want to enjoy the cosy warmth on your patio even in the cool evening hours from an IR radiant heater, you will have to keep an eye on – and control of – the incurred electricity costs. Nevertheless, IR heaters work and heat much more economically than many may initially believe. On the basis of an example calculation, you can very easily determine your demand, including the costs, yourself.
In most cases, infrared radiant heaters have an output of between 1000 and 4000 watts. Depending on the size of the patio, this kind of heating output is necessary in order to be able to produce cosy heat at any time. Let’s take a heater with a heat output of 2000 watts for example. One kilowatt hour of electricity currently costs an average of 29.16 cents in Germany. The 2000 watt IR heater thus costs 58.32 cents per hour in electricity at full heat output. However, most modern infrared heaters from Trotec allow you to select between different heating stages, either using an integrated knob or by remote control. This allows you to adjust the radiant heat to the outside temperature or the size of the heated surface and thus save energy and heating costs.
Overview of the maximum heating area of infrared radiant heaters for outdoor use:

Use this formula to calculate the required heat output in watts for your patio size
Formula: m² x W/m² = W
Patio area (m²) x recommended heat output per square metre (W/m²) = required heat output of the infrared heater (W)
Reading and calculation example:
For a 12 m² terrace size in a protected area with very good insulation quality, the recommended heat output is: 12 m² x 150 W/m² = 1,800 W.
