Commercial&Residential Heating Uses
- No hypoxia, No CO poisoning compared with vent free space heaters (infrared heaters or blue flame heaters) on the market.
- Annual gas fuel savings up to 20-30% compared with wall-hung boiler system.
- Much bigger power input than electric room heaters.
- Simple installation and operation.
- Quick solution for heating small individual spaces, such as families, offices, stores.
- No need for a heat distribution network.
- Simple to control with a thermostat.
- Easy maintenance.
HOW IT WORKS
This kind of gas room heater is a stand-alone appliance serving to heat an individual small space and capable of operating on propane or natural gas.
The equipment usually includes a heat exchanger, through which a fan blows air from the room to be heated.
Combustion air comes from outside is preheated when the flue is forced to be discharged outdoors, so there is no worries of hypoxia and CO poisoning.
- Natural gas or LPG.
- Rates 5/7/12kW
- Wall mounted or free-standing installation
- Combustion air comes from outside is preheated when the flue is forced to be discharged outdoors
- Room air is heated quickly with high efficiency by forced circulation
- 12VAC/24VAC low voltage control system
- Easy operation control panel on heater with separate remote-control device and timer
- Overheating protection, flame monitor, exhaust pipe clog protection
- Heating area: 20-70m2
Heating Area Volume & Climate Zone
The required kW output required is primarily dependent upon the area to be heater and the climate zone in which you live.
The following rough guide assumes your ceilings are no higher than 2.4M:
Very Cold Zone: 1kW output required for each 8.5m²
Cold Zone: 1 kW output required for each 10m²
Cool Zone: 1kW output required for each 13 m²
Mild Zone: 1kW output required for each 16m²
The indicated gas heating areas would be adjusted down by 5% for each of the following conditions: house built on pillars (non-slab), no carpets on floors, no drapes on windows or a ceiling height exceeding 2.4m. Deduct an additional 10% if the area does not have ceiling insulation. Please note that this is only a guide and individual home designs and situations may vary.
Gas Heater Sizing Example #1:
You live in the Cold Zone and you want to heat an area 5m X 10m, which equals 50m².
Because 1kW will heat 10m², you should need a heater with a 5kW output.
Gas Heater Sizing Example #2:
Same as the previous example but in this case your ceilings are over 2.4m and you have wood flooring instead of carpeting. You would need to deduct 5% for each of these two items. So, instead of 1 kW heating 10m², it would heat 9m² (10% total reduction). This means you would need a heater with 5.6 kW of output (50 ÷ 9).
- The minimum clearance between the room heater and the combustibles must meet the manufacturer’s requirements
- Reserve enough space for maintenance
- The exhaust pipe is inclined downward by minimum 3°
- The outdoor part of the exhaust pipe is kept away from combustibles and cannot be covered or shaded by snow
- When installing on the wall, the bottom of the heater is 200-500mm away from the ground
- Gas leaking alarm and emergency gas shut-off valve are highly recommended.
