Keeping your space warm is very important – this is the place where you can do something and as you stay there, you need to create a comfortable environment. Finding the best garage heaters is quite tricky. It is crucial to determine the heater size for garage.
If it is too small – you will not be able to heat up space or you will have to use too often, which may cost you much (do not forget about the fuel price). If the model is too powerful – you will not use it to its maximum or it may be non-effective. A garage is not large so the best option is finding a compact solution that generates the required amount of heat.
Another important factor to consider is the seasonal temperatures – some areas do not have cold winters. The calculation is quite easy here – if the average temperature is around 15 degrees (outside) and you need to have around 60-65 degrees inside, then, the solution should increase the temperature by around 45-50 degrees (this amount is important for the final equation).
Measuring your space
Heating your garage requires understanding how large space is. There are two simple steps here:
- Square footage. Multiple the width by the length of the space interior. Therefore, if the garage is 30 by 20 feet, then the square footage is 600 square feet.
- Cubic footage. To calculate the cubic footage you need to multiply the value you got by the ceiling height. Therefore, if you the ceiling height is 10 feet, then the cubic footage is 6000 cubic feet (10 x 600)
Preserving the heat
Generating the necessary amount of warmth is not the only problem. If you do not preserve it, then you will have to force your heater work on and on, which leads to unnecessary expenditures. It is a great idea to insulate your garage. It determines the garage heater size – if you can preserve the generated warmth, then you do not need to use a heater frequently and it cuts the costs.
BTU or British thermal unit will show you precisely how powerful the heating solution has to be. The final equation considers insulation (or its absence). The final equation looks like:
Insulation quality factor x total footage x the required heat = BTU.
The insulation quality factor may be 0.5 for high-quality insulation, 1 is for average, 1.5 means you have not perfect insulation and 5 is for the complete absence of insulation.
Electricity and gas are two main types of “fuel” for such models. Electric is 100% efficient – all the consumed electricity is turned into heat, while gas is not 10% efficient, but the natural gas as a fuel is cheaper and it can be a better option if you use it frequently.
