Discover How To Save Up To 80% On Your Hot Water Bill... Average Savings of Up To £1,000 a Year

Take advantage of 0% VAT on survey, supply & fitting


Energie Thermodynamic Hot Water Solar System

ENERGIE’s Thermodynamic Solar Systems harness a technology inspired by the foundational principles of thermodynamics, pioneered by French physicist Nicolas Carnot. 

This innovative system enables our solar panels to capture heat not only from direct sunlight but also from ambient sources like rain and wind,
operating continuously throughout the year.

Our customers who have already taken advantage of our hot water systems are loving it because they’re:

  ✅ Much more efficient than outdated hot-water systems

  ✅ Getting hot water exactly when it’s needed

  ✅ Cheaper to run with fewer moving parts

  ✅ Available for retrofitting or for replacing your existing water cylinders

  ✅ Come in a choice of sizes to fit in your space

  ✅ Come with a 25-year guarantee

  ✅ Attract 0% VAT (because the government endorses this as a renewable energy product)

But more importantly, they’re
saving on their electric bill by heating 80% less water each month.

Which averages out at roughly £100 per month on an average bill.

Typically, these hot water systems pay for themselves by 4-6 years on average.

Nothing else on the market compares.

Photovoltaic Intelligence

Achieve the perfect balance between PV production and consumption through our intelligent controller, optimizing the utilization of renewable energy resources.

How Does It Work?


The evaporation of the fluid that runs inside the closed looped circuit happens on the solar panel by capturing the heat from the sun, wind, rain and surrounding air by natural convection.


The heated fluid then travels to the compressor, that will compress the fluid increasing its pressure and also it’s temperature. Then it goes to the heat exchanger where this heat is transferred to the water.


An expansion valve will make the pressure and temperature drop to sub-zero values. The fluid travels up to the thermodynamic solar panel and the cycle repeats again.

Upgrade Your Existing Hot Water Tank

Replace your existing water tank with a highly insulated vented or unvented indirect duplex stainless steel hot water cylinder, integrated with Thermodynamic Hot Water Solar System unit for greater efficiency and savings.


Retrofit To Your Existing Water Tank

Thermodynamic Hot Water Solar System can be retrofitted to your existing hot water tank, which means you can save money without having to replace your water tank.

How Efficient Is It?

Thermodynamic Hot Water Solar System is a modern and efficient way of heating water for your home. It uses advanced technology to capture heat not only from direct sunlight but also from ambient sources like rain and wind, operating continuously throughout the year.

Subsequently, the heated fluid moves to the compressor, where it is pressurized, elevating both its pressure and temperature. Next, it proceeds to the heat exchanger, where the accumulated heat is transferred to the water. 

Following this, an expansion valve facilitates a drop in pressure and temperature to sub-zero levels. The fluid then cycles back up to the thermodynamic solar panel, repeating the process anew.

The Energy Saving Trust also notes that solar-assisted heat pumps can be an attractive option for households that are off the gas grid and currently rely on oil, LPG, or electricity to heat their hot water. They estimate that such households could save up to £1,140 per year by installing a solar-assisted heat pump.
