Patio Heaters: Natural Gas

Natural gas is a great fuel for heating your outdoor room. It is both inexpensive and reliable. As it is a permanent installation there is no need to worry about needing to refuel the heater. This guide contains information on the following:

Styles of Natural Gas Patio Heaters

Natural gas patio heaters are installed permanently and may need to be installed by a professional. They are available as full-size units fixed into the ground or as ceiling/wall mounted units.

The in-ground natural-gas units typically heat a larger radius than the portable propane units. In-Ground units are ideal for commercial establishments.

The Natural Gas Ceiling mount heaters produce the same amount of heat yet remain out of the traffic areas allowing people to pass directly underneathe,  which is the warmest area produced.

Cost of Operation

Natural gas patio heaters have the lowest cost of operation compared to propane and electricity.

On average a patio heater rated at 40,000 BTU's will cost an average of 48 cents per hour.

Performance and Heating Range

A typical full-size natural gas patio heater will output 40,000 BTU's and will distribute the heat to up to a 20' diameter area (314 sq ft). The exact heating range and output will depend on the design of the patio heater and wind conditions.

Natural Gas burns hot and extremely clean. Compared to propane it produces less green house gases.

Once lit, the natural gas patio heater produces its full range of heat immediately. There is no waiting for an element to heat up.

Safe operating Procedures

Before using any natural gas appliance you should check for any damage. If you smell gas do not start the patio heater. Before starting the heater follow these steps to check for a leak:

  • Prepare a cup of soapy water
  • Liberally apply the soapy water to the gas line
  • Look for any bubbles
  • Repair any and all leaks by tightening or replacing lines, hoses, fittings, and connections. Once the leaks have been repaired, the patio heater is ready for use. Do not deviate from the manufacturer-authorized way of testing, repairing, and servicing.

If you smell gas, but cannot see a leak contact your local fire department and leave the area.
