PRODUCTS & SERVICES Products of the month Lochinvar launches latest high-temperature heat pump With high energy efficiency and low environmental impact, the pump is ideal for a diverse range of settings L ochinvar has unveiled the latest addition to its product line-up, the Amicus Altus high-temperature air to water heat pump. Designed to produce hot water at temperatures of up to 70C, the heat pump maintains high energy efficiencies while minimising environmental impact. Available in three configurations two-pipe heating only, two-pipe heating or cooling, and four-pipe simultaneous cooling with heating and heat recovery the Amicus Altus is versatile and suitable for various commercial projects. Its ability to achieve high temperatures makes it an ideal low carbon replacement for gas boilers in buildings with high hot water demands, without requiring extensive remodelling of heating or hot water systems. This flexibility provides a valuable solution for achieving net zero carbon goals and reducing energy costs without significant upfront capital investments. One of the standout features of the model is its use of the low global warming potential (GWP) refrigerant R290 (propane). Unlike traditional alternatives such as R410A, with a GWP of 2,088, R290 boasts an incredibly low GWP of just three. R290 is also environmentally friendly, with zero ozone depletion factor, according to the Intergovernmental Panel on Climate Change and a GWP over a 20-year period that remains below one. Additionally, R290 does not contain polyfluorinated chemicals, which are subject to stricter regulations in the UK and Europe. By incorporating this non-hydrofluorocarbon R290 refrigerant, Lochinvar has embraced a forward-thinking approach that aligns with the UKs phasedown timetable for eliminating higher GWP substances from heat pump applications. This move follows the European F-gas Regulation and demonstrates Lochinvars commitment to environmentally responsible solutions. Under the current phasedown timetable, the UK is looking to eliminate fluorinated gases (F-gases) from most heat pump applications by the end of the decade. This is in line with the European F-gas Regulation that the UK continues to mirror despite its departure from the European Union. The Amicus Altus units offer cascading 76 September 2023 www.cibsejournal.com Lochinvars new Amicus Altus heat pump capabilities, with outputs ranging from 88kW to 880kW and an impressive coefficient of performance (CoP) of up to 5.5, with a seasonal CoP of approximately 3.95. These units can operate in heating mode even at external air temperatures as low as -20C. With built-in controls and a BMS fault and remote on/off signal that prioritises hot water production, the Amicus Altus is user-friendly, easy to install, and supported by Lochinvars offer of free site visits for every installation. We are delighted to be bringing such an impressive step forward for heat pump technology to the market, said product engineer Steven Hunt. Air to water heat pumps are generally highly energy efficient, but the Altus also delivers hot water temperatures comparable with those that end users are used to with conventional gas boilers. The new product follows Lochinvars launch of the UKs most powerful heat pump water heater, the Amicus AquaStore, last year. It has an output of 8kW and 455 litres of hot water storage capacity in a compact, monobloc package combining heat pump and storage vessel. It can deliver up to 65C hot water in both efficiency and hybrid modes, and up to 490 litres in a peak hour with a 50C temperature rise. Air to water heat pumps offer flexibility for integration into various heating systems, making them a viable option for different building types and installations. Despite higher initial installation costs compared with gas boilers, the long-term savings and reduced carbon footprint make heat pumps an attractive solution for sustainability-focused projects. The Amicus Altus joins Lochinvars extensive Amicus range of air source heat pumps, ideal for diverse project sizes and applications, from residential to commercial and industrial. Lochinvars commitment to providing comprehensive solutions with heat pump technology at the core simplifies the design, specification, and installation processes for customers, ensuring a seamless transition to low carbon heating. Heat pumps are playing an increasingly important role in helping the UK transition to low carbon heating. The Amicus Altus is just the latest in a line of innovations designed to make the technology available to the widest possible range of users with minimal disruption to the existing building services, said Hunt.
