Alva GH312 3-Panel Infrared Radiant Indoor Gas Heater 4.2 kW

Three-Panel Radiant Heating for Indoor Spaces

The Alva GH312 gas heater uses three ceramic infrared panels to deliver radiant warmth to rooms up to 50 m². Separate burner chambers cut gas odour and raise efficiency at each of the three heat settings. A high-gloss black steel body and four castors let the unit move between living areas, bedrooms and offices.

Output ranges from 1.55 kW on one panel to 4.2 kW across all three. Gas draw measures 305 g/hr at position 3, 175 g/hr at position 2 and 90 g/hr at position 1. The unit runs on LPG at 2.8 kPa through a 0.59 mm injector.

An integrated piezo igniter sits in the control knob, so startup needs no separate tool. The heater accepts a 5/8-inch bullnose valve on a 9 kg cylinder or larger. A hose and bullnose regulator ship with the unit. The oxygen depletion sensor and flame failure device cut gas flow if the pilot goes out.

Key Features

• Three Ceramic Infrared Panels
  Radiant heat reaches occupants and surfaces without warming the air first.

• Variable Dial Control
  Three positions select one, two or three active panels for stepped output.

• Safety Interlocks

  • Oxygen depletion sensor monitors room CO₂ levels
  • Flame failure device closes the gas valve on pilot loss
  • Positive off at the control knob

• Cylinder Compatibility

  • Fits 5/8-inch bullnose industrial valves
  • Runs from 9 kg LPG cylinders and larger
  • Hose and regulator included

• Independent Burner Chambers
  Each panel carries its own burner, which reduces odour transfer and lifts combustion efficiency.

• Pressure and Injector Match
  The 0.59 mm injector meters LPG at 2.8 kPa for stable flame height across the three positions.

• Mobility and Placement

  • Four rotary castors roll on hard floors and carpet
  • 750 mm height clears most furniture lines
  • Black high-gloss finish on a steel shell

• Standards Compliance
  The appliance meets SANS 1539, with SANS 1237 for the regulator and SANS 1156-2 for the hose.

Why Choose the GH312

• Radiant output from three ceramic panels warms people and surfaces directly, which suits rooms with high air exchange.

• Separate burner chambers keep odour low, a practical factor in bedrooms and shared offices.

• The 4.2 kW ceiling matches open-plan living areas, while the 1.55 kW low setting stretches runtime on a 9 kg cylinder.

• Piezo ignition and a positive-off knob remove the need for matches or separate lighters.

• SANS compliance gives procurement teams a documented safety baseline for indoor LPG appliances.
