Space Heaters
Target Scope
Space heaters using gas or oil for fuel, except the following:
1) ones of unvented type,
2) ones using gases other than either those of City Gas 13A group or liquefied petroleum gas for fuel,
3) vented gas space heaters,
4) vented oil space heaters with maximum fuel consumption of over 4.0L/h, or
5) direct vent type oil space heaters with maximum fuel consumption of over 2.75L/h.
Energy Consumption Efficiency
Energy consumption efficiency shall be heat efficiency (%) measured in the manner stipulated in JIS S 2122 or JIS S 3031.
Categories & Target Standard Values
In the target fiscal year and each subsequent fiscal year, for each category, the weighted average value obtained by weighting energy consumption efficiency with shipment volume shall not be below the target standard value*1.
| *1: For Category E of oil space heaters, the weighted average value obtained by weighting standard energy consumption obtained from the standard energy consumption calculation formula with shipment volume. |
●Gas space heaters
| Category | [Target standard value] Standard energy consumption efficiency |
|---|---|
| Direct vent type | 82.0 |
●Oil space heaters
| Category | [Target standard value] Standard energy consumption efficiency or calculation formula | ||
|---|---|---|---|
| Air supply and exhaust type | Heat transfer type | Category name | |
| Direct vent type | Natural convection type | A | 83.5 |
| Forced convection type | B | 86.0 | |
| Vented type | Radiating type | C | 69.0 |
| Other than radiating types with maximum fuel consumption of 1.5 liters per hour or less | D | 67.0 | |
| Other than radiating types with maximum fuel consumption of more than 1.5 liters per hour | E | E=－3.0L+71.5 | |
| Remarks: | E and L shall express the following numeric values. |
| E: Standard energy consumption efficiency (unit: percent) | |
| L: Maximum fuel consumtion (unite: litters per hours) |
Target Fiscal Year
FY2006 and each subsequent fiscal year
Energy Efficiency Improvement
●For gas space heaters whose target fiscal year was FY2006, energy consumption efficiency was improved by about 1.8% compared with the FY2000 level in the target fiscal year (FY2006).
●For oil space heaters whose target fiscal year was FY2006, energy consumption efficiency was improved by about 5.3% compared with the FY2000 level in the target fiscal year (FY2006).
