Emerging technology ~ thermodynamic solar panels

By Katie Anderson on October 30, 2012

If you’re looking for an alternative to solar hot water heating then you might want to give some thought to thermodynamic panels. The emerging renewable energy technology is starting to steadily make a name for itself.

Thermodynamic panels are a revolutionary way to provide constant hot water and heat for our homes. Just think of it like an advanced solar water heating system and an air source heat pump combined. The thermodynamic panels are made from weather protected anodized aluminium. which weigh in at just 8 kilograms, and systems comprise of a 250 litre or 280 litre hot water cylinder which will be able to provide enough hot water to easily meet the needs of a family of five. They work by using reverse refrigeration technology which converts heat from the atmosphere into hot water and space heating for your home all year round, 365 days a year.

Available in outputs of up to 53kW thermodynamic solar panels deliver 55°C hot water. A one panel system will be able to provide your household with constant hot water, whilst a 4 panel system will provide central heating.

These innovative new systems are a major advancement in solar thermal technology, not least because while conventional solar systems operate using daylight, thermodynamic panels will work 24/7. Yes, during the day and at night. And that’s just one of a number of reasons why the technology is beginning to generate such a buzz.

How does it differ from solar thermal?

Thermodynamics are up to four times more efficient than conventional systems. Not only that, but this type of technology doesn’t require a secondary heat source, unlike traditional solar thermal panels. Which means it’s time to say bye bye to immersion heaters.

What are the benefits of thermodynamic panels?

It is an emerging technology but the advantages speak for themselves. Thermodynamic panels are a good choice and here’s 10 reasons why:

  • Systems will provide 100% of your hot water needs
  • They work day and night
  • Systems can operate in temperatures as low as -15°C
  • You’ll get continuous hot water on tap 24/7 365 days a year
  • You can save up to 70% on your annual energy bills
  • Panels can be mounted on your roof or vertically onto a wall
  • They’ll help to lower you household’s carbon emissions
  • There’s very little maintenance required
  • Installations are simple and straightforward
  • The technology has a COP rating of 3 to 6

How does the technology work?

In thermodynamic technology energy from the atmosphere is absorbed into a special fluid which circulates through the weather protected anodized aluminium panels.

Once the fluid leaves the panels it is compressed into a hot gas which flows through a coil in the hot water cylinder which heats the water. Last but not least the gas travels through an expansion valve in the system and is transformed back into a fluid.

Only F-Gas registered installers should be enlisted to install thermodynamic technologies which can be used for:

  • Providing daily hot water
  • As a complete heating system
  • To heat a swimming pool

Will the technology be eligible for the RHI?

Presently the technology isn’t be eligible for the Renewable Heat Incentive (RHI) scheme when it is introduced, although that could change. As a general rule renewable heating systems below 45kW capacity must comply with the Microgeneration Certification Scheme, but after undergoing an initial review of the technology the Microgeneration Certification Scheme (MCS) has temporarily suspended installers being able to register thermodynamics. Requirements for the installation of this technology type needs to be developed further by MCS before suspension can be lifted. It’s worth noting, however, that thermodynamic solar panels can still be installed, they just aren’t currently eligible to register with MCS.

Systems below 45kW capacity must comply with the Microgeneration Certification Scheme.

System sizes and costs

Thermodynamic solar panels are the next generation in solar water heating. Available in outputs up to 53kW a one panel system will cost in the region of £4,500.

So for hot water and central heating day and night think thermodynamic solar panels.

Did you know?

Earn Money via the Feed-In TarrifThe Government's Feed-In Tariff was launched on April 1st 2010 to encourage homeowners to generate their own electricity - it is split into two methods of revenue.

The Generation Tariff earns you a fixed income for every kilowatt hour of electricity you generate. And, The Export Tariff earns you income for every kilowatt hour you generate and sell back to the grid.

An average 3/4 bedroom house fitted with 2.5kw Solar PV panels and normal electricity usage would earn over £850 p/a tax free!

Add this to an approximate £145 reduction in your electricity usage and you could benefit by over £1,000 per year.

N17 - Dear Sirs, I am interested in the Thermodynamic System for Domestic Hot Water as well as Heating System. Potential panel/panels will be installed on the wall just under the roof. The gap between the wall and the panel should be not less than 250mm due to planned 100mm insulated render system which will be installed on the wall afterwards. External wall is cavity wall build from bricks Please provide the price for both systems. The prices should be broken down between labour and materials. Could you also provide technical information about panels & hot water cylinders and other equipment. House size: 3 bedroom, 1 bathroom, Kind Regards, ····· ·····
Southgate SA3 - We are thinking of replacing our combi boiler with a conventional system with a hot water storage tank and would like to incorporate a solar thermal system. Our roof is south facing.
