i-HOT Domestic and Commercial Hot Water solutions
i-Hot
Next generation of Thermodynamic Solar Heat pump, specially designed for domestic and commercial hot water production.
i-HOT Solar Assisted Heat Pumps combine the benefits of Solar Energy and Heat Pump technology all in one.
The i-HOT is our brand new air source water heater, designed to provide hot water to your home or offices quickly, sustainable and efficiently. Our Thermodynamic Solar Heat Pump is a cutting-edge solution for Domestic and commercial Hot Water production, perfectly suited to residential properties. Available in capacities from 120 to 5000 litres, it offers flexible configurations with 1 or 2 thermodynamic solar panels and storage tanks in Stainless Steel 444 or Duplex 2205, with or without an additional coil.
The sun does not always shine. Winter days in Great Britain have an average of seven hours of light and only a few hours of sun. This lack of sunlight limits the effectiveness of traditional solar panels. The i-HOT thermodynamic solar panels overcome this constraint, the i-HOT system heats all the water for your family or commercial business with great efficiency and major energy savings, even on rainy days and at night, 24 HOURS A DAY / 7 DAYS A WEEK / 365 DAYS A YEAR
i-Hot energy efficient HOT Water Heat Pump solutions, working on renewable, sustainable and energy-saving solar technologies.

Solar Assisted Heat Pump Water Heaters How it Works
i-HOT Thermodynamic Solar Assisted Hot Water Heat Pumps are very effective because they combine the principles of heat pumps with solar thermal collection, allowing them to extract heat from the ambient air and the sun, even at night or in cold, cloudy weather.
A solar assisted heat pump heats water by absorbing heat from direct sunlight and from the air, the hot water is then stored in a hot water cylinder, ready for when you need it. i-Hot Solar assisted heat pumps can also work without direct sunlight, this is because heat pump technology transfers energy from outside to heat your water. A solar assisted heat pump (SAHP) works by drawing in heat from direct sunlight and the surrounding air via a large, flat panel known as an evaporator. This panel contains a special fluid that absorbs the captured heat and transfers it to the heat pump through heat exchange. The heat pump then raises the temperature further and stores the hot water in a Stainless steel cylinder, ready for you to use whenever you need it.
Why choose our i-HOT solar Heat Pump Water Heaters?
The ECOTOP, SOLAR BOX, AQUAPURA, ECO XL, THERMOBOX DUO, AQUAPURA INVERTER ranges Solar Assisted Hot Water Heat Pumps have a various number of benefits, making it a particularly interesting system for producing hot water. Its main advantage is that it uses free and inexhaustible energy, simply the sun and the air!
Up to 70% less consumption. That’s the energy a i-Hot Solar Thermodynamic water heater consumes compared to an old inefficient immersion heater model. In fact, although this type of water heater requires electrical assistance, it still allows for energy savings of up to 70%. It is possible to connect the water heater to renewable sources, existing photovoltaic solar panels to make it more environmentally friendly.
