Solahart Atmos Eco Split

Heat Pump Water Heater

The Solahart Atmos® Eco Split 5kW Heat Pump is a smart, energy-efficient heat pump, designed for people looking for an energy-efficient alternative to an electric water heater but whose homes may not be suitable to install a solar hot water system and whose outdoor space is limited.
This outstanding two-part unit comprises a refrigeration/heat exchanger module that’s similar to a split air-conditioner, and a water tank which can be installed near, or at a distance, depending on the requirement.
