Thermodynamic Hot Water Systems VS Solar Thermal Water Heating

  • Unlike solar thermal, thermodynamic systems do not require constant sunlight …
    The UK apparently sees on average 133 days a year of rain or snow (that’s just under 37% of the year), thermodynamic systems work on a thermodynamic principle, and have been ingeniously designed to work in all weather (including sub-zero temperatures). They take their energy from a variety of climatic elements, as opposed to being reliant on sunlight, which is how they are able to work all year round.

  • Solar thermal systems cannot be retrofitted to your property, whereas thermodynamic hot water systems can, meaning that there is minimal fuss and interference.

  • Thermodynamic hot water systems can serve as a fully reliable and independent source of hot water heating, unlike solar thermal, which can only give your existing hot water heating system a boost on days of sufficient sunlight.

  • Solar thermal systems cannot be programmed or adjusted, thermodynamic systems on the other hand can be pre-set and tailored to heat water according to your family’s needs, with the added benefit of a ‘boost’ button when needed.

  • Thermodynamic hot water systems are a newer and more advanced type of renewable technology, working on the ground-breaking thermodynamic principle of heating. The technology surrounding solar thermal systems is in no way as effective as these.

Making the Right Choice

At JEM Energy we appreciate that investing in a renewable system (especially if it is the first time), can be rather overwhelming, and sometimes being sure that you are putting your hard earned cash into the right system for you, that will ensure you see a reduction in your utility bills, as well as playing your part in taking care of the planet - can be equally mind boggling.

It is for that reason that we want to help you to be sure that you are spending your money wisely.

In our view, the Bunsen Air Thermodynamic Hot Water System, is the best possible method of renewable water heating and the only one that will ensure a higher energy cost saving return on your investment…. move aside solar thermal, there’s a new kid on the block!

Thermodynamic Water Heating Systems

Thermodynamic Water Heating Systems

How they work, safe water temperatures, and the true temperature of the water produced by them

What is a thermodynamic hot water system?

Thermodynamic water heating systems are designed to absorb energy from a range of climatic elements and do not require the sun to heat water. They do this through a circuit of three main parts…

The first is their external thermodynamic hot water panels, which take in energy from any atmospheric element including wind, snow, hail and rain. Secondly, these panels are linked via specialist refrigeration piping to the internal heat pump unit, and then thirdly, heat energy is transferred to the hot water cylinder, which all household hot water is then taken from.

A full description of how thermodynamic hot water systems work can be found here.

Do thermodynamic hot water systems generate water that is hot enough for domestic use?

According to the Recommended Code of Practice for Safe Water Temperatures, there has been evidence to indicate that the risk of scalding rapidly increases from temperatures of 45°C and above… For example, partial thickness burns will occur within 30 seconds at 55°C.

The Consumer Product Safety Commission (CPSC) recommends setting to no higher than 49 °C (120 °F), although is to my understanding that medical professionals do not recommend heating bath or shower water to over 43.4°C, as any hotter than this can be harmful to health.

Thermodynamic, and solar assisted heat pumps are ERP tested to be able to heat your water to 53°C, they are also capable of heating water to a maximum of 60°C once a week (the required temperature for legionella control).

The speed that thermodynamic hot water systems achieve this temperature

The Bunsen Air Thermodynamic Hot Water system is one such high quality system of its kind. Field trials, carried out by manufacturer Solamics, have demonstrated the remarkable speed that a hot water cylinder can be heated back up to temperature through the use of a thermodynamic system.

The result drawn from this test was exceptional…

1. To recover the cylinder temperature from 30 to 53 ℃, Bunsen unit took 2 hours and 1 minute in total.

2. The COP in outdoor temperature at 8 ℃, water temperature from 30℃ to 35℃, is 7.3.

The COP was measured up to 35℃ as this reflects the COP of a standard heat pump.

Will there be enough hot water to go around?

After the water heating process has taken place, there is enough hot water generated to accommodate the use of an average domestic household. As the heating process is continuous, a sustained supply of hot water is ensured. Should even more hot water be required, there is a ‘boost’ function on the system controller, allowing users to increase the target temperature!


How to get hold of one

JEM Energy are suppliers of the Bunsen Air, and have already carried out hundreds of successful installations across the UK.

Customers who have had their systems installed for as little as three months, are already reporting savings of as much as £60 a month, as well as acknowledging that their systems are heating water that is more than hot enough for domestic bathing and washing purposes, as well as reporting that their systems are supplying enough hot water to accommodate their entire household.

Tyburn Covent - Bunsen Air Installation

Tyburn Covent - Bunsen Air Installation

This month saw the installation of four Bunsen Air | Thermodynamic Hot Water Systems, on the premises of Tyburn Convent in London

Solar energy company JEM Energy - installers of the Bunsen Air | Thermodynamic Hot Water System, were recently commissioned with not one… but four Bunsen Air installations on Tyburn Convent in London

Tyburn Convent was established in 1903, near the site of the Tyburn Tree Gallows - famous for hosting the executions of a number of historical and well-known public figures (including Oliver Cromwell and Roger Mortimer).

More importantly for the Tyburn Nuns though, is the Martyrs' Shrine at their Convent where more than 350 Catholic Martyrs are honoured, and of whom there are 105 known Martyrs to have been executed on the Tyburn Tree Gallows. They witnessed to their faith by dying for it during the Reformation, including among others St Edmund Campion and St Oliver Plunkett. The Sisters keep the memory of the Martyrs alive and pilgrims and tourists from all over the world visit the Shrine of the Martyrs at Tyburn

The convent is now home to an enclosed order of Benedictine sisters, who still form a community within its walls.

Looking for a Modern and Renewable Water Heating Solution

JEM Energy got word that the convent was looking to modernise their water heating methods earlier this year, and that they were hoping to introduce a reliable, renewable source of water heating to the building, which would still ensure that the sisters residing there, would be provided with enough hot water all year round, and not just during hotter months.

The only way to guarantee renewable hot water all year round, is with thermodynamic water heating technology. Solar thermal systems, and other similar hot water heaters, simply cannot be relied upon for the entire year, as they still require a back-up method of water heating to generate hot water during cooler months of less sun exposure.


Installing Four Bunsen Air | Eco Water Heating Systems

Due to the size of the convent, access points to water cylinders and pipe work, and the number of people living there (who would all require hot water on a daily basis), it was decided that an installation of four thermodynamic hot water systems - would best suit everyone’s needs.

One double Bunsen Air system was connected to a larger hot water cylinder, alongside another Bunsen | Thermodynamic Water Heating System, which was connected to a smaller cylinder. One further Bunsen Air was installed on the far side of the convent... so four Bunsen Air systems were installed in total.

As the Bunsen’s solar collector panels needed to be relatively close to the internal Bunsen Air Units, some of the thermodynamic hot water panels were double stacked twice, so they were infact… quad-stacked on a side wall.

This does not impact their operational levels, it just saves on space, and ensured that the specialist refrigeration pipe work connecting the external and internal components of the thermodynamic water heaters wouldn’t be over-stretched!

According to all accounts, and despite being one of JEM Energy’s more challenging installation commissions, this large scale installation went extremely well, with all four Bunsen Air systems connected comfortably, making Tyburn Convent a fantastic example of the greatest possibilities when it comes to modern renewable systems being integrated into very old, and in this case – historic settings… and how these possibilities can easily become reality.


 Bunsen Air reviews from the Convent

Since their quadruple Bunsen Air installation, Tyburn Convent has contacted JEM Energy to say that they are so happy with their Bunsen Air | Thermodynamic Water Heating systems, they would like to install a further 2 on the building and its grounds!

JEM Energy can only say how honoured they are to have been able to provide this service to Tyburn, and that they are so glad to have installed the Bunsen Air as the convent’s chosen system for hot water.

“Thank you for choosing us, and trusting us to install our modern renewable hot water system, on your wonderfully monumental and historic building – this is what makes our job so worthwhile!”



A Great Little JEM of an Idea!

A Great Little JEM of an Idea!

The ‘Feed in Tariff’ deadline is fast approaching, and JEM Energy don’t want you to miss a fantastic opportunity to create essentially FREE hot water, by integrating solar panels, with a solar thermodynamic hot water system.

By taking advantage of the Feed in Tariff scheme before it closes to new applicants on the 31st March 2019, you could be paid for generating free hot water for yourself!

What is the Feed in Tariff scheme?

The Feed in Tariff scheme, which is a scheme that has been put in place by the government, to reward home owners for investing in certain types of solar energy systems, by paying them for generating solar energy - will be closed to new applicants from the 31st of March 2019.

Renewable energy systems included in the scheme are - solar photovoltaic (solar PV), wind, micro combined heat and power (CHP), hydro and anaerobic digestion (AD).

Who we are and how we can help

JEM Energy are a UK solar energy supplier and installer, primarily based in the south of England, who supply and install solar pv systems, and more recently – thermodynamic water heating systems.

Solar pv panel systems can be installed on a roof, a shed, or ground mounted, making them quite handy and versatile little things.

They work by generating power in the form of electricity, as they absorb energy from the sun, which is converted into electricity. This electricity can then be used to power the home, all without the polluting and harmful burning of fossil fuels!

The Feed in Tariff scheme is inclusive of solar pv panels such as these – what you chose to do with the electricity they generate… is up to you!

Using solar pv panels to generate the electricity required to run a thermodynamic hot water system

Thermodynamic hot water systems have only been around for a few years, but have fast become a recognised form of renewable energy.

Comprising of two main parts – two externally mounted thermodynamic panels, and an internal thermodynamic heat pump unit, the main benefit of thermodynamic water heating systems, is that they do not require sunlight to generate hot water, and instead take their energy from other sources including wind, rain, snow and extremely low or extremely high temperatures – they have even been referred to as ‘night time solar’, as they can work at night!

Solar PV Panels

Thermodynamic Hot Water Panels

Thermodynamic Hot Water Panels

Thermodynamic hot water systems do require a very small amount of electricity to power their integral heat pump, which is responsible for converting the energy taken from their external thermodynamic panels, into hot water.

Unfortunately though, thermodynamic hot water systems are not included in the Feed in Tariff scheme, however the electricity needed to power their integral heat pump could be…

The rated electrical power of our thermodynamic water heating system, is only 444w, running on average at around 500w

Solar pv panels are capable of generating over 500w of electricity on a day with ample sunlight (although how much they generate totally depends on how many panels you have, and where they are situated).

Therefore, they are more than powerful enough to provide the electricity required to power a thermodynamic heat pump.

By installing just 2 solar pv panels on your home, alongside a thermodynamic water heating system, and doing so before the Feed in Tariff scheme closes to new applicants on the 31st March, you could be paid for the electricity generated by your solar pv panels, and use this electricity to power the heat pump within your thermodynamic hot water system.

Meaning that you would literally be paid for supplying yourself with free hot water!

What would happen to any unused electricity?

If there was any electricity left over after powering your thermodynamic hot water system, it would simply contribute to the running of other household appliances such as a fridge/freezer, lamps, chargers etc.

If you already have solar pv panels installed on your home, then it isn’t too late to apply to the Feed in Tariff scheme, it also isn’t too late to add a thermodynamic hot water system to your property, and start being paid to generate free hot water!

JEM Energy believe that you should be rewarded for the solar energy you produce, and for investing in it in the first place.

For more information on how we could help you do this, contact us here.

Haven’t you heard… it PAYS to install solar energy - but only until the 31st of March!!!

Haven’t you heard… it PAYS to install solar energy - but only until the 31st of March!!!

The Feed in Tariff (FIT), is a UK Government Department of Business, Energy and Industrial Strategy (BIES) scheme, to pay homeowners and small scale businesses for generating renewable energy, through their solar energy systems such as Hydro, Wind Turbine and of course... Solar PV.

However, it was announced on the 18th December last year, that this scheme would be closing to new applicants on the 31st March 2019 – YIKES!

So, with this closure deadline now looming over our heads... have you managed to arrange the installation of your Solar PV system yet?

Solar PV

According to government data, the installation of UK Solar PV systems in January this year, where compared to January last year, has increased by 55% with 3,759 reported Solar PV installations carried out this month alone.


This rapid increase, is highly likely to be due to the Feed in Tariff deadline, with many UK households jumping at the chance to be paid for their solar energy generation, before the opportunity passes them by.

How JEM Energy can help

JEM Energy are licensed installers of Solar PV systems, and provide a reliable service to our customers across the South of England.

We can offer you friendly, no obligation advice regarding the FIT deadline, our Solar PV systems, and how installing one could benefit your family, alongside Solar PV installation quotes.

If you are looking to harness the opportunity to be paid for the renewable energy you generate, then it is paramount that you get in touch with a solar energy supplier as soon as possible, to ensure your application can be completed for the 31st March.

If you have already been considering renewable energy solutions, but have just been waiting for what feels like ‘the right time’, then please DON’T let an opportunity like this pass you by!

What am I?

  • I was officially launched on to the UK market last year following my Energy Efficiency - A rating

  • I am a new form of solar heating technology and the product of 12 years research and development into the best heat pump technology and thermodynamic principle.

  • I work by transferring the abundant energy in the atmosphere through both my externally mounted solar collector panels to your domestic hot water cylinder

  • I can provide for 100% of your hot water needs 365 days a year

  • I have been specifically developed for the UK environment and do not rely on sunlight

  • I like all weather, rain, hail, snow and wind, and can remain efficient in extremely low temperatures

  • I even work at night

  • I am a low energy system and require very little electricity to run

I am the Solamics Bunsen Air Thermodynamic Hot Water Pump

Did you know… I can simply retrofit to any existing hot water cylinder, or be installed with a new one, turning the hot water cylinder into a solar system which can generate 100% of your hot water requirements.

How do I work?

My two thermodynamic solar collector panels are fitted outside your property either on the roof, wall or mounted from the floor, and an o zone friendly refrigerant which naturally boils at -26 degrees, moves through my panels, harvesting the FREE energy from the air and outside weather.

As my refrigerant heats up, it changes state from a liquid to a ‘super-heated’ vapor. The ‘super-heated vapour’ flows back to my Bunsen Controller where heat is transferred via my heat exchanger directly to your hot water cylinder.

Did you know… I can be programmed to suit your lifestyle, turning on when you need me. When I am set to automatic mode, I also turn on when I detect a 5°C in air temperature, and will heat your water cylinder back up to 55°C.

Who created me?

Solamics Ltd, I am manufactured in China but I am designed for the UK! JEM Energy install me in the South of England.

Did you know… I have been receiving some amazing feedback from installers who have described me as being 35% more efficient than any similar systems they had encountered.

Why me and not another similar system?

  • I am affordable

  • I am initially sold as a dual panel system – dual panels = higher power

  • I am the first system of my kind to feature dual exhaust technology, this means that I give higher power and efficiency which single flow channels cannot achieve.

  • As I have superior reheat times, I actually spend very little time running each day, and most of my time in Stand By.

  • I have been independently tested for noise levels, performance and power

  • I have exceptional noise levels of just 41db

  • The estimated energy saving I could apply to your hot water is around 70% compared to a standard electric water heating or immersion heater.

  • I feature a next generation rotary compressor for higher power and efficient recovery times

  • Rated electrical power of just 444w

  • I can be set to different target temperatures for different times – so I run less and can be isolated when not needed

Did you know… I am a fully reliable source of hot water heating and can be used to heat your water entirely all year round day and night.
