Johnson & Starley's range of WarmCair condensing warm air heaters includes 36kW and 46kW versions that are suitable for light commercial applications such as schools, nursing homes, small hotels, public houses, retail outlets, sports halls, and community centres.
The heaters are suitable for both new build and for replacement heating upgrade installations.
These WarmCair Condensing heaters are available in both upflow and downflow models, offering low running costs, exceptional reliability, high efficiency and warmth, low carbon and low NOx emissions, well within the limit of Class 5, as well as low operational noise levels.
As a condensing appliance, WarmCair uses less energy to produce the required heat compared with a similar sized non-condensing heater. The additional heat energy is produced by passing the exhaust flue gases through a secondary heat exchanger where the heat is transferred into the air stream. As a result, latent heat, which would otherwise escape and be lost to atmosphere, is substantially recovered and utilised in the heat delivery process. In this way, up to 98% thermal efficiency is achievable.
Trials have indicated, energy consumption savings of up to 28%, compared with non-condensing heaters. The savings over a non-condensing warm air heater are made in both gas and electricity - the gas savings are through the condensing technology and the electrical savings through the use of fan motor technology, using EC rather than AC control. Energy efficient operation is also achieved through the inclusion of a fully modulating burner and combustion controls as well as long life stainless steel heat exchangers.
A major benefit of warm air heating systems is the rapid initial heat up period which is substantially less than half of that of wet systems. Sophisticated controls then enable the precise amount of heat output to match the demand. There is also the option of an electronic air cleaner, whilst a summer air circulation facility is standard.
A WarmCair heater can replace any existing warm air heater with minimum disruption and with replacement installation times generally less than one day. The heaters are included in the Energy Technology List (ETL) and will be eligible for Enhanced Capital Allowances (ECA, Annual Investment Allowance) when installed in commercial enterprises, for up to 100% first year tax credit.
