SunStar SGLMG Marine Grade Glass Patio Heater Features

  • 316 Stainless Marine Grade Body: Built from 316 stainless steel for harsh environments: coastal patios, salt air, pool decks and waterfront dining. Painted steel heaters corrode in those spots long before the burner wears out.
  • Two Stage Glass Patio Heater: Runs at 24,000 BTU on low and 35,000 BTU on high. Low covers mild nights and high handles cold ones, so you are not burning full output when you do not need it.
  • Tinted High Temperature Glass: The glass front protects the flame on windy days and gives the heater a clean look under any decor. SunStar rates it wind resistant up to 40 MPH.
  • Radiant Warmth Where Guests Sit: Infrared heats people and objects at floor level without first heating the air, so an open patio stays comfortable. One heater covers about 12 ft by 12 ft in light wind.
  • Flexible Mounting: Chain suspension or wall mounted, horizontal up to 60 degrees. The optional stainless heat shield lets ceiling clearance drop to as little as 10 inches.
  • Remote Or Wall Control: Models ending in 10 include the hand held two stage remote. Models ending in 7 use a switch or thermostat from the optional add-ons below.

SunStar SGLMG Marine Grade Glass Patio Heater FAQ

How is the SGLMG different from the standard SGL?

The SGLMG body is 316 stainless steel marine grade, made for salt air and harsh environments. The standard SGL comes in black. Output, size and clearances are the same as the SGL35.

Where should I use a marine grade glass patio heater?

Waterfront restaurants, pool decks, coastal homes, marinas and any site where salt or moisture would corrode a painted heater.

What do the 7 and 10 in the model number mean?

Models ending in 7 have no remote and run from a wall switch or thermostat. Models ending in 10 come with the hand held two stage remote control.

How much area does one SGLMG heat?

About 12 ft by 12 ft in minimal wind. Use the sizing and layout guide below to space heaters on a larger patio.

Can I reduce the ceiling clearance?

Yes. The optional stainless steel 316 marine grade heat shield brings the horizontal ceiling clearance down from 20 inches to 10 inches.

Does it run on propane or natural gas?

Both are available. Pick the fuel your site has when you order; the L models are propane and the N models are natural gas.

Who can help me choose the right model?
