The pulse combustion heater includes a combustion chamber and at least one exhaust pipe forming a resonant system with a chamber. The combustion chamber has an internal cavity of flattened spherical shape which causes combustion gases returning to the combustion chamber to flow into the cavity in a double toroidal flow pattern. The apparatus has an exhaust which includes a primary exhaust pipe of a length selected to that combustion of gases is complete before the gases leave the pipe. The pipe terminates at a manifold to which is connected helical heat exchange coils from which heat is transferred to a fluid circulated around the coils.
