Heat pumps are therefore a highly efficient and environmentally friendly solution for centralised DHW production, as they have a lower carbon footprint than other alternative solutions on the market, such as those using natural gas. In addition, it reduces installation costs and makes them safer by eliminating gas installation. As it is centralised, it takes up less space on the roof and significantly reduces installation and maintenance costs.

Keyter has a range specifically designed for this type of application. ARGIA air-to-water high temperature heat pumps for hot climates with high performance also for medium conditions. With the capacity to supply water at a high temperature of +65^oC, being able to accumulate DHW at 60 ^oC even with outside temperatures of 5 ^oC. It also has a hot gas heat recovery system for DHW. Keyter ARGIA units are available with plate heat exchanger or multi-tube heat exchanger and have a high seasonal energy efficiency thanks to multi-scroll technology.
