Save energy bills with a solar assisted heat pump

A better return on your money

The typical return on investment for a thermodynamic system is between 8-14%, rising each year as energy prices increase, a far superior return than with any high street savings account.

£10,000 invested today in a savings account might generate you £350 in a year, spend less on thermodynamics and get more back!

Enjoy the benefits of generating your own energy, enough to produce 100% of your domestic hot water requirements and of course, with thermodynamics you are using less finite fossil fuels which is kinder to our environment.

Energy Prices

Energy Bills Rise By 36% In Three Years

Gas and electricity prices are rising at up to eight times the rate of earnings, warns Citizens Advice (17th November 2013).

50% Bill Increase

Energy UK warns that household bills could rise by 50% over six years. Chief executive blames government policies and network costs, as EDF becomes latest supplier to increase prices.

Ofgem Issue Warning

Annual fuel bills for the average household have reached £1,420. This is according to reports released by Ofgem, government regulator for gas and electricity markets in Great Britain.

Save on Energy

On average a boiler is responsible for around 80% of the home’s energy use, reducing the use of your boiler can make major savings.

Why rent when you could buy?

You are already paying each month for the energy you use to generate your hot water, immediately after installation you stop paying this to the energy company and use the savings to fund your thermodynamics system, effectively the difference between renting or buying your energy.

The money you spend each month on generating hot water, you will never get back and with energy prices continuing to rise year in, year out due to dwindling resources, your savings will continue to increase, allowing you to fund your purchase sooner.
