Wood Stove Product Comparison: 5kW Size

March 7, 2019

The 5kW size is the perfect stove for serious heating in a larger small space, or one in an especially cold climate. For larger RVs and full sized buses in colder climates, larger sized tiny homes and cabins, or yurts, a stove in the 5kW range can provide plenty of heat through the Winter without overwhelming your space. A stove that’s just the right size will allow you to burn longer, cleaner, more efficient fires, and can make it possible to burn your stove earlier in the Fall and later in the Spring without making your home uncomfortably hot.

In this article, we provide an apples-to-apples comparison of small stoves in the 5kW range, (approximately 15,354 – 20,474 BTU/hr).   Because the BTU claims of some manufacturers vary wildly relative to their actual performance (why?), we've grouped stoves based on which ones work best for small spaces within this BTU range (according to the Tiny Wood Stove BTU Calculator), regardless of the manufacturer's claimed output.

Warning: Most BTU calculators are designed to overestimate your heating needs, which can result in a stove that's so large, you can't burn it without overheating your space.  If you're not sure which size stove you need for your small space, run through the Tiny Wood Stove BTU Calculator, which is specifically designed for sizing wood stoves for small spaces.
