How Much Propane Do I Need With a Martin Propane Heater?

by Hunter Kissam November 15, 2022 3 min read

Martin propane heaters require low maintenance, clean energy, and a sleek fireplace design. These are just a few reasons they're so popular, not to mention their built-in safety features, room thermostat, and long-lasting products.

Of course, we could go on. Still, if you want a wall furnace for your home or work spaces, you will need to consider the size of your propane supply. Here's what you need to know!

Measuring Your Space

First, you will need to determine the size of your living space that you intend to heat. If this is supplemental heat, then simply measure the room or space you want to supplement. If it's a primary heating source, then you will need to include wall spaces, and you may need more than one wall heater.

Simply grab your measuring tape and multiply the length and width together! For example, if your space is 20x40', then you will have an 800 sq ft space.

Determining Your Heating Needs

First of all, how hot do you like it? 20 BTUs per sq ft is generally the minimum, but you may want a higher room temperature for maximum comfort. In that case, aim for 30 BTUs per sq ft and plan for a larger propane supply.

Also, you may want to consider the height of your ceiling, as this can make a big difference. 20 BTUs is good for an average ceiling height of 7 or 8 feet, whereas an 11-foot ceiling may need more heat. A ceiling fan can make a big difference, but this is still something to consider!

Finally, if you're heating multiple rooms, you need to consider heat dispersion for better heat flow into your other rooms. A fan will do the trick, but doors will need to stay open!

Choosing a Propane Tank Size

If you live in remote locations out of range from any propane delivery services, then your options are limited to whatever you can transport yourself. If a 20, 30, or 40-pound tank is all you can get, we recommend having at least 3 or 4 on hand for larger spaces.

For most living spaces, a 120-gallon tank will do the trick. If you need to heat a 500 sq ft space, then a 20,000 BTU direct vent wall heater should be more than enough. In this case, you'd only need to refill your tank twice a year in most cases.

If you have the space for it, a 250-gallon tank will ensure that you can go the entire winter for a reasonable space.

Once you have it set up, follow the easy installation kit that comes with the original packaging. Just determine your wall's thickness, connect the propane tank to the back of the unit, and it's good to go! Check out our installation guide for more information!
