Can a masonry heater run without electricity?
The beauty of a masonry heater is in the simplicity of its design. There are no fans or pumps in masonry heaters EXCEPT when a heater heats water, but does not have a place above the heater for the water storage tank. If the storage tank is above the heater and in close proximity to it, a natural thermosyphon effect will circulate the water from the heater to the tank. In cases where you cannot install the tank above the heater, you MUST use an electric pump to circulate the water.
