Walker Riserless Core - 3rd year review of a Rocket Mass Heater

A Rocket Mass Heater is a woodburning stove that heats up a mass of some kind during its burn time. The fire then goes out and heats you and your house from the stored energy. In this case we have a bench which acts as the 'battery', but other things have been used such as beds and walls.
I should mention that when I recorded this video the stove had not been fired for a little over a month and I had only ran it for 15 minutes or so. This explains the low temperatures when I take out my laser-guided-temperature-measuring-device-thingy. Normally they would be way hotter.

Here is a video of Matt Walker showing us his first iteration of this stove. He later created better versions but that was after we built our stove. Check out his channel for those amazing options.
