HydraTherm’s Llewellyn Ward talks about HVAC products that ensure payback periods are minimised, and returns maximised. Latest in water-heating solutions

A newSouthAfrican company is pro- viding high-tech, energy-efficient water-heating solutions to the residential, commercial and indus- trial markets. Their units have been shown to produce savings of around 70% of total hot water costs, a significant contributor to lower electricity bills. Since they use less than a third of the energy of an ordinary geyser, these units qualify for installation in terms of SANS 10400XA and XA2. HydraTherm’s expertise lies in the design and specification of centralised hot water plants for large commercial projects, as well as in offering premium solutions for smaller projects and domestic homes. Water heating products can also be supplied on demand, to meet exact specifications, where specialised solutions are required. “Our full-service solutions are ideal for hotels, laundries, dairies and hospitals, the retail and manufacturing industries, and private homes at a highly competitive level of investment,”saysmanagingdirectorLlewellyn Ward. “We aimto ensure payback periods are minimised, and returns maximised.” The HydraTherm range of high qual- ity, efficient hot water heat pumps includes ‘traditional’ split pump technology, where an external heat pump is piped to a separate water storage vessel, and an integrated unit where the heat pump is mounted on top of thewater tank. Heat pumps are proven touse roughly a third of the electricity required to heat the same amount of water in a conven- tional geyser element. The range includes two 60 °C integrated heat pumps for residential use, 55 °C and 60 °C split hot water heat pumps for residen- tial, hotel and commercial use, 70 °C split hot water heat pumps for hotel and commercial use and 80 °C split hot water heat pumps for laundry, dairy and medical use. Technology and materials HydraTherm heat pumps are manufactured using the latest technology and best possible materials. All parts and components are care- fully selected and tested to ensure ultimate efficiency, reliability and durability. Vapour injection (EVI) technology combined with highly efficient air-to-water heat exchang- ers results in improved efficiencies in a wide rangeof ambient temperature conditions and

nominal co-efficient of performance figures of up to 4.5:1. High quality Saginomya four-way revers- ing valves provide defrost functionality and ensure that low ambient temperature operation is possible. Hydrophilic coated fin evaporator coils improve efficiency and reduce corrosion, while the patented C&S tube-in-shell heat exchangers with counter- flowdesign, improveheat exchangeefficiency and reliability. Thewater tank ismade fromSUS316L ‘low carbon’ stainless steel, and incorporates two electric impressed current anodes in addition toamagnesiumsacrificial anode. This ensures corrosion is virtually eliminated, even in the harshest of environments. “We supplyonlySABSapprovedT/Psafety valves and drain cocks. In terms of our prod- uct warranty, installation compliance with SANS10254andSANS10142-1ismandatory,” notes Ward. Units for large-scale commercial use are designed to be space-efficient. The integrated heat pump resembles an ultra- modern domestic appliance andwill comple- ment the architecture and aesthetics of any home. The product features a smart control panel, with intuitive on/off push button, and temperature and operating mode controls. Installation is as straightforward as that of an ordinary geyser.

Another advantage of the HydraTherm’s integrated heat pump is the centrifugal fan assembly and egg carton-style sponge noise- damping material. This reduces the overall sound level to just 45dBa, which translates to less than the sound of normal human speech or domestic refrigerators. Whether working with a hospital, dairy, factory or private residence, the company strives tosupplyonly thehighest qualityprod- ucts, workmanship and service. Every project taken on – no matter how big or small – is carried out with precision, and completed to the exact specification of the client, architect or engineer. HydraTherm’s three principal members have been in the plumbing industry for over ten years, withhe senior director having been in the industry longer than25years. This com- binedexperienceallows forflexibility. “Where unique solutions are required, we also design heating products on demand to meet exact specifications,” Ward confirms. “We are very excited to launch these sophisticated products and look forward to revolutionising this sector. As impressive as our products are, we are not merely in the business of supply. We provide the full spec- trum of services, from initial consultation, all the way through to personal after-sales service andour revolutionary ‘cloud’ support,” he concludes. q
