Stiebel Eltron Australia has introduced its latest range of instantaneous water heaters designed for energy efficiency and sustainability.
Given the rising energy costs, commercial as well as domestic users can reduce this significant outgoing by installing efficient and effective hot water systems. Instantaneous electric water heating specialist, Stiebel Eltron Australia (SEA) has released the company’s newest single-phase electric instantaneous water heaters to support this requirement.
According to Glenn Day, Sales Director for SEA in Queensland, the DHCE series has been introduced based on the company’s experience and understanding of the Australian market developed over the past 20 years. He explains the DHCE series instantaneous electric water heaters are ideal for a range of commercial and domestic situations and are designed to service single or multiple hot water outlets or low flow showers depending on the incoming cold water temperature and available flow rate for the associated tapware.
The DHCE series instantaneous electric water heaters are available in a choice of three single phase models. The DHCE 6/50 and the DHCE 8/50 deliver hot water to a maximum of 50°C, and are compliant with AS 3498-2009, which covers the heating of water used in places of personal hygiene and allows the machine to be installed without the need for an external tempering device.
The third model, the DHCE 8/60 delivers 60°C hot water, and is recommended for use in facilities suitable for disabled users where the mandated outlet temperature is 43°C, which must be controlled using thermostatic mixing valves. To be most effective, the inlet hot water supply to most valves must be at least 10°C above the required outlet temperature, making the DHCE 8/60 model an ideal choice.
A low-flow switch in all three DHCE series models allows the unit to start heating the water with a flow rate as low as 1.5 litres per minute. The DHCE instantaneous water heaters are ideal for low flow tapware ensuring that hot water is delivered at low flow rates.
Instantaneous electric hot water systems achieve the lowest levels of water wastage of any hot water system available, partly through their capacity to reduce delivery pipe lengths, and partly through the ability to heat water faster than competing systems. The DHCE heaters can be used as a booster unit in commercial installations where there are long deadlegs between a storage heater and any outlets. The water at the point of use may require minimal additional energy to bring it up to the required temperature. The electronically controlled thermostat switches off the heater when the water reaches the set temperature.
The compact design of the DHCE range, combined with water connections on the rear and bottom of the unit, allows the water heaters to be installed as close to the point of use as practical. Possible installation locations include inside a cupboard or a Euro laundry, or mounted on a wall under or over a sink.
According to Day, standalone instantaneous systems offer many advantages by ensuring water is only heated at the time of use, energy is not wasted in maintaining a stored volume of hot water, operating costs are reduced and less water is wasted by the user while waiting for sufficiently hot water to arrive to the outlet.
