A DIY unit can be done with about $1200 in materials



Rocket Mass Heater:
Less than $100 to build, or you can buy one outright at $1250 (code compliant liberator cost)

When compared to other types of home heating, Rocket Mass Heaters are very cost-effective. For example, a gas furnace will cost about $600 per year to operate, while a Rocket Mass Heater will cost about $100 or less per year to operate. This means that over the course of 20 years, you could save up to $8000 by using a Rocket Mass Heater!

Natural Gas


Propane

According to the National Renewable Energy Laboratory, the U.S average cost for a residential propane system is $ 2,552

However, the type of propane system you choose will greatly affect the cost. If you choose a tankless system, the cost could be as low as $1,500. However, if you choose a system with a tank, the cost could be as high as $4,000.

In addition to the cost of the system itself, you will also need to factor in the cost of installation. Installation costs will vary depending on the type of system you choose, but they typically range from $500 to $2,000.

Wood Stove

The average cost to install a wood stove in a standard 2000 square-foot home is between $500 and $2000. However, if you hire a professional installer, the cost can be as high as $5000.

On average, it will cost between $2,000 and $3,000 to install a modern wood stove in your home. This number will obviously change based on the size and style of the stove, but the average cost will give you a decent idea of what to expect.

Pellet Stove

The size of the average home in the United States is approximately 2000 square feet. It is safe to say, then, that the cost to install a pellet stove in an average home would be approximately $2000. This cost includes the purchase and installation of the stove, as well as the cost of the pellets themselves. The average cost of pellets is $250 per ton, and a typical pellet stove will burn one ton of pellets per month.
