The Future Is Renewable with Air Source Water Heaters

Air is all around us, so utilising it to heat your water is a smart decision. The Aquafficient Eco+ uses the warm air in your home to provide your hot water. A refrigerant is compressed, enabling the transfer of heat to the water in the Aquafficient Eco+ system, so you can enjoy water heated to up to 60°C. This convenient, and eco-friendly, air source water heater is the perfect solution to home energy efficiency and is up to two to three times more energy-efficient than a conventional water cylinder†.

The Aquafficient Eco+ requires minimal maintenance. As an added benefit; a single 1.5 kW robust, titanium heating element is also built-in as a backup, meaning you will never be without hot water.

Saving Energy

The Aquafficient Eco+ is proven to reduce energy consumption which can make a real difference to those energy bills. The table below shows an energy use comparison with a 210 litre water cylinder with a 3kW immersion heater. Switching to an Aquafficient Eco+ could reduce your energy use by a third.‡

The reduction in energy usage with the Aquafficient Eco+ is down to the  ‘Coefficient of Performance’ (COP) of the unit, which means for every 1 unit of electricity you use, you receive at least 3+ units of heat

You can simply multiply the annual kWh usage by your current electricity tariff to calculate an estimated running cost, however any figure calculated is for illustrative purposes only and is not guaranteed.

This domestic hot water heat pump available to homeowners provides incredible convenience and energy savings.

Built with a stainless steel casing, 80mm of highly efficient insulation and finished in white, Aquafficient Eco+ has a sleek, modern design perfect for any home.
