Product Description

This rocket heater barrel cap fits a standard 55 gallon steel drum. The barrel cap is cast from a dense refractory with a special high temperature mesh for reinforcement in the middle. On the underside, it has a groove for the rim of the metal drum. A barrel gasket to fit in that groove is included. The gasket keeps the exhaust gasses from entering your living space. The refractory is also thermal mass in your system and will provide additional heat storage for your rocket heater.

It has a groove at 24" which fits perfectly over the rim of the drum. It is 26" in diameter and 1½" thick. Use it with any of these rocket heaters:

  • 6" portable metal box or
  • 6" barrel build or
  • your own rocket mass heater design which incorporates a 55 gallon steel drum

For optimum usage, we recommend that you cut the top of your barrel out from within the welded rim so that the exhaust hits the barrel cap directly. The refractory material can handle the high temperatures better than the steel of the drum adding longevity to your system.

You can also use the warm surface for heating food.

The cap can be painted with any of our high temperature paint colors to dress up your rocket heater. The pictures above show the cap plain and painted.

THE CAP DOES NOT COME PRE-PAINTED.
