Rinnai is introducing the KCM series of continuous flow hot water heaters into the UK market. The KCM series is designed to specifically increase customer savings in energy, capital, and carbon footprint with the inclusion of internally refined technological advancements. It operates at 93% efficiency. The KCM unit has micro-processors to ensure hot water is delivered at the exact pre-set temperature. The advanced micro-processors will also measure incoming water temperatures and modulate gas input. This guarantees the system will only use the required amount of energy to increase water temperature whilst supplying limitless volumes of clean hot water. The inclusion of micro-processors enables the customer to pre-set water temperatures supporting the minimization of Legionella and eliminating the risk of safety issues such as scalding.
