What is the AquaHeater Plus Smart?

What it does

The AquaHeater Plus Smart heats up fresh water for use in washer extractors  (eg as a hot fill). For instance, the AquaHeater Plus Smart will heat up to 2.4 m³/h, from 10°C to 70°C. The integrated buffer tank stores any hot water that is not immediately needed. This water can be used whenever required, a feature that ensures a smooth hot water supply even during peaks in demand.  The high quality tank insulation ensures minimal standing heat losses from the buffer tank. The AquaHeater Plus Smart is compact so it can generally be positioned exactly where the hot water is needed, giving a flexible, decentral system without the  heat losses of big central systems and at a fraction of the cost. If you currently heat your water electrically, then you will be surprised to see how much you can save by (pre)heating your fresh water using gas technology.

Performance boost

Your fresh water is now (pre)heated efficiently and inexpensively for use in your washer extractor(s). Ongoing high costs associated with electrical heating or  steam generation and distribution losses are a thing of the past. The buffer tank offers hot water supply flexibility. Should demand increase significantly, then an extra AquaHeater Plus Smart is easily added to expand capacity. All these features add up to a performance boost with greatly increased flexibility and lower costs. Gas water heating offers large benefits for a modest investment.

How it works

The heart of the AquaHeater Plus Smart is state-of-the-art Dutch gas burner technology.  The burner modulates automatically as demand fluctuates, so that the gas used at any given moment is only exactly as much as needed. No extra heat is wasted in temperature ‘overshoot’. The condensing technology in the heater yields efficiency levels of 99% (gas use) compared to levels between 50% and 80% in traditional steam boilers. This technology has been used in the Netherlands for a number of decades, the AquaHeater Plus Smart puts the very best of this know-how to work in an adaptation specifically for smaller textile laundries.  The insulated tank, which is an integral part of the AquaHeater Plus Smart, offers a buffer of hot water at exactly the required temperature so that any fluctuations in demand are smoothly dealt with. No need to wait for hot water anymore. A graphic display shows operators exactly what is happening, real time. The AquaHeater Plus Smart allows you to get the maximum out of precious ressources like water and fuel. Easy CO2 savings to boot.

The AquaHeater Plus Smart is carefully designed to be ‘plug-and-play’, made for quick, easy installation and minimum fuss.
