Radiant heater seasonal efficiency
Radiant heater seasonal efficiency (heat generator seasonal efficiency) is: ‘…equivalent to thermal efficiency (net calorific value). For flued appliances, the manufacturer of the radiant heater should declare a thermal efficiency measured to the test standards EN 1020[1] or EN 13842[2] as applicable. The calculation of the thermal efficiency (net calorific value) should:
- take account of the radiant heater and associated flue pipe/ tailpipe within the building envelope
- exclude fans.’
[1] BS EN 1020:2009 – ‘Non-domestic forced convection gas-fired air heaters for space heating not exceeding a net heat input of 300 kW, incorporating a fan to assist transportation of combustion air or combustion products’.
[29] BS EN 13842:2004 – ‘Oil-fired convection air heaters – stationary and transportable for space heating’.
