Advanced Electric water heaters for commercial applications

Established water heater manufacturer Lochinvar has launched a range of high performance electric floor standing storage water heaters for commercial and large residential applications.

Cavalier water heaters are available in seven models all of which meet the requirements of the EcoDesign (ErP) directive and can operate at working pressures of up to 8 bar.

These fully packaged water heaters represent a significant advance for this type of technology because they feature factory-fitted multiple immersion elements for rapid hot water production. This ranges from three 3kW elements in the lowest output model (9Kw) up to nine 6kW elements powering the highest output (54kW) water heater, which is capable of providing up to 929 litres of continuous hot water per hour at a temperature rise of 50ºC.

The immersion elements operate in sequence to provide fast recovery of hot water and better efficiency, especially during off-peak demand periods. The independent operation of each element provides stand-by in the unlikely event of any individual element failure.

Cavalier water heaters also work seamlessly with Lochinvar’s Amicus range of heat pumps when installed as part of a ‘hybrid’ system, making them ideal for projects requiring a hot water solution with zero on-site emissions. As they produce no on-site carbon or NOx emissions, they are BREEAM and ‘London Plan’ compliant.

Storage capacities are either 200 or 300 litres and the enamelled steel storage vessels include an integral magnesium anode for cathodic protection. They are insulated with 65mm polyurethane foam and encased in an enamelled grey jacket to ensure heat losses are substantially lower than the standard required by Part L of the Building Regulations.

The Cavalier range is designed for ease of maintenance with all of the electrical components accessible from the front of the units.

“This product is an important addition to our portfolio as we are seeing growing demand for all-electric, zero on-site emission solutions in a wide range of buildings,” said Lochinvar sales director Liam Elmore.

“High efficiency electric products like this are the most convenient installation choice in many projects. The rapid decarbonisation of UK electricity supplies is further strengthening their case,” he added. “When combined with heat pumps, they tick all the boxes for energy, environmental protection and running costs.”
