To help contractors and end users meet air quality targets, Lochinvar has developed a low NOx emission version of its Charger direct gas fired commercial water heaters.
The Charger fast recovery water heaters have been used in a wide range of commercial and industrial applications for more than 40 years. As a result, there is now a growing market for replacements.
The new Charger low NOx range consists of three models, with storage capacities ranging from 294 to 328 litres and hot water recovery rates from 850 to 1600 litres/hour. NOx emissions are between 33mg/kWh and 45mg/kWh, depending on model – well below the 56mg/kWh maximum stipulated by the latest ErP regulations.
The largest model – at almost 90kW output – will deliver 1600 litres of hot water per hour at a temperature rise of 50ºC. All three models are designed to replace any comparable atmospheric water heater and come with the option of low-level draught diverters to ease installation.
Featuring an enamel-lined steel storage vessel, the water heaters are able to operate at pressures of up to 8 bar. Each vessel includes sacrificial magnesium anodes to provide cathodic protection and the burner sits at the base of the unit. The use of baffled flue ways improves heat transfer and provides fast hot water recovery. A multifunctional control valve incorporates flame failure safety, operating thermostat and high limit thermostat.
“Providing low NOx versions of some of our most popular water heaters is essential to give contractors and end users choice and flexibility,” says sales director Liam Elmore. “When it comes to replacing ageing units, we will always encourage users to switch to higher efficiency condensing water heaters, but often this will not be an option.
Often the most convenient and cost-effective way to replace an old non-condensing water heater is with a similar product and, by offering low NOx versions, we can ensure customers also comply with ErP legislation and improve air quality.”
Lochinvar introduced a low NOx version of its Knight range last year. Both Knight and Charger low NOx water heaters are held in stock at the company’s Banbury facility, making delivery available to most areas of the UK within two working days.
