Our easy-to-use Infrared heater calculator estimates the power required to heat a given room so you can easily choose the size of the infrared heater you need.
How does the Infrared Heater Calculator work?
Choosing the right Infrared Heater means you have to find the right size of the heater for each room. The Infrared Heater Calculator uses a formula to determine the required power. The power is measured in Watts. All heaters have a nominated Wattage output noted as kilowatts (kW). A kW is a measure of 1,000 watts of electrical power.
What size Infrared Heater do I need?
First, you have to determine the volume of the room by multiplying the room length, width, and height.
Second, choose the type of isolation:
- Extremely advanced insulation – 26 watt / m3 (~ 0.73 watt / ft3)
- Good insulation – 30 watt / m3 (~ 0.85 watt / ft3)
- Moderately insulated – 34 watt / m3 (~ 0.96 watt / ft3)
- Old build, poorly insulated () – 38 watt / m3 (~ 1.08 watt / ft3)
- Very old, airy windows, not insulated at all – 42 watt / m3 (~ 1.19 watt / ft3)
The given values above are good if the targeted room temperature is 21 Celsius (69.8 Fahrenheit).
Finally, here is the formula to calculate the infrared heater size: room length x room width x room height x isolation value.
This is an important decision because choosing too little power means you’ll stay cold, and too much power will mean you spend more on energy than what’s necessary. With all this in mind, you should also talk to a professional before making a purchase because the calculation run with this calculator does not replace a precise technical plan created by an expert.
How to use the Infrared Heater Calculator?
Our Infrared Heater Calculator can be used to work out the size of the heaters that you require. First, you need to enter the following details:
• room dimensions (length, width, height in meters or feet)
• the type and efficiency of the isolation
If you are ready with this, just hit the Calculate button and the wattage needed to heat the room will now be shown.
Can infrared heaters heat a house?
Yes, infrared heaters can heat a whole house. These modern electric heating solutions offer a deep level of warmth for your living room, bathroom, bedroom, etc.
What are the advantages of infrared heating?
- The heat is felt almost instantly.
- Infrared heating does not dry the air.
- The heater’s efficiency is very high.
- The placement of pipes is not required for the installation.
- Because infrared panels heat objects, air circulation is limited.
- You can ventilate without heat loss.
What are the disadvantages of infrared heating?
- Heating with electricity could be more expensive.
- The air remains relatively cold
- Infrared heaters should not be obstructed by objects.
- Electric infrastructure (cables, fuses, etc.) needs to be improved.
- You lose the heat the moment the unit turns off (infrared heaters not warming the air).
- Infra panels can get exceptionally hot.
How long do infrared panels last?
The average expected lifespan of an infrared heating panel is around 100,000 hours or 30 years duration. The amount of maintenance that most infrared heaters require is minimal. This technology requires no moving parts, which means you don’t need to worry about a fan motor wearing out. You won’t have any air filters that you’ll need to replace. Lubrication is not necessary either. Your only job is to clean the reflectors every so often to ensure that the heat can reach its maximum range all of the time.
