Gas powered heat delivery system

A gas powered heat delivery system, comprising:

• a fuel gas supply;
• a catalytic heater connected to the fuel gas supply;
• a fluid delivery circuit comprising a tank containing fluid,
• a one way conduit having an inlet for receiving fluid from the tank, an outlet for delivering fluid to the tank, and a heat delivery section, the fluid in the fluid delivery circuit being heated by the catalytic heater;
• a rolling diaphragm pump connected to the one way conduit for pumping heated fluid through the fluid delivery circuit, the rolling diaphragm pump being connected to the fuel gas supply to operate the rolling diaphragm pump;
• and
• a switch for switching the fuel gas supply between the rolling diaphragm pump and the catalytic heater, the switch being operated by the rolling diaphragm pump.
