Thermodynamic Solar Panels FAQ

Thermodynamic solar systems use a technology based on the principle of the French physicist Nicolas Carnot, who discovered thermodynamics.
Thanks to him, thermodynamic solar panels are capable of capturing the heat from the sun, or even from the rain and wind, 24 hours a day, 365 days a year.

What does thermodynamic solar panels do?

One of the innovative aspects is that an ecological fluid at freezing temperatures circulates through the solar panel, allowing a greater uptake of the solar energy and a higher absorption of the environmental energy that is then released to the water through a heat exchanger. Thus, thermodynamic solar panels surpass the limitations of the traditional solar panels and make possible a more efficient increase of the water temperature.

Does this type of solar panel produce electricity?

No – thermodynamic solar panels do not produce electricity. Thermodynamic solar panels can be used for: heating sanitary water, heating large volume water, acclimatisation of swimming pools heating and central heating.

Does this equipment work as a heat pump?

The equipment associated with thermodynamics is not classed as a heat pump. The heat pump is a device that requires mechanical ventilation which causes large energy consumption and excessive noise. In addition, at low temperatures, you need to use an electric heater to eliminate frost which seriously undermines its performance.

Do I need to keep my water heater or buy a special module?

A thermodynamic solar system is sufficient to ensure you receive hot water all year round, with high energy efficiency. You don’t need to have any special module or maintain any support system, such as a geyser or water heater.

Can I have hot water in days without sun?

Because the fluid passes inside the panel at very low temperatures, it can receive more solar energy than a normal liquid and even on days without sun or at night. Because of this thermal difference, the solar panel can capture the heat existing in the environment and transmit it to the water. Thus, the system always ensures hot water up to 55ºC.

What’s the payback period for the investment?

The average investment return for sanitary hot water equipment is about 4 years. Your energy bill will be significantly reduced by hundreds of pounds every year. A thermodynamic solar system will diminish the impact that energy costs have on your home.

Is the equipment approved and certified?

Yes, all of the equipment we use follows the European standards of quality in accordance with the directives 2006/95/EC and 2004/108/EC and is also certified by CERTIF and SOLAR KEYMARK.

Does the system require extensive maintenance care?

Maintenance is almost non-existent. You are just advised to check the magnesium anode, a protection element of the tank, once a year.

Do these systems consume energy? What is the energy consumption?

Thermodynamic solar systems are devices of low consumption and high efficiency. The existing electricity consumption serves only to make the ecological fluid circulate and not to produce heat, unlike the traditional systems. For example, the ECO 250 ESM system can provide hot water for a family of 4/5 people with energy consumption 4/5 times lower than the consumption of a traditional geyser or of an electric water heater.

Does this system have any anti-bacterial device?

Yes it does. According to the standard in force, the equipment for sanitary hot water has a function that allows the tank’s temperature to be raised to over 70ºC, whose activation is manual with automatic deactivation.

Is the installation quick and easy?

Yes it is. A thermodynamic solar system for the heating sanitary water can be installed in less than 1 day.

Does it come with a warranty?

The warranty period of the solar panel is 5 years against manufacturing defects and corrosion, though the average lifetime of a thermodynamic solar panel is around 20 years. The tank has a 3 year warranty, if it’s in stainless steel and a 2 year warranty if it’s enamelled or galvanised.

At what distance must the panel be from the tank?

The distance should not exceed 15m in height and/or 30m in terms of distance.

Do the panels have to be installed on the roof?

No. Thermodynamic solar systems are very versatile and can be installed either on the roof or on a flat roof, terrace, balcony, on the soil, etc.

Is it necessary to reinforce the roof and to request a planning permission to carry out the installation?

It is not necessary to reinforce the roof or to request a planning permission to carry out the installation. A thermodynamic solar panel weighs only 8 kg and measures 2m in length by 0.8m in width and has a gross coverage of 1.6m2. The thickness of a panel is 20mm.

Can the panels be placed in any direction?

Yes, but they should preferably be south facing to ensure the equipment’s maximum efficiency.

Can the solar panels be painted?

Yes the solar panels can be painted, preferably in dark colours, so that the panel can be easily integrated into the architecture of each customer’s house, without compromising its efficiency.

What temperature can be reached in a bath?

Approximately 55ºC (temperature allowed by law).

What are the defining features of the fluid? Can it be dangerous in the event of leakage?

The used fluid is completely safe, non-toxic and environmentally friendly, so if there’s a leakage there will be no problem for the user’s health and safety.

Is it necessary to make temporary fluid charges?

Because the primary circuit is completely sealed, you don’t need to make any temporary charge, thus ensuring lower maintenance and greater longevity of the equipment.

Will I have hot water when there is no sun for several days, with snow or on a very windy and with freezing outside temperatures?

Yes, there will always be hot water to use.

Is there more heating with 2 panels?

Heating takes up little more than half of the time. For example: For 300 litres, the average heating time with one panel is 6 hours, and with two panels it is four hours, with the water always at 55°C.

Is there the possibility of multiple simultaneous showers?

Yes, without the loss of temperature or water pressure.

How many panels are needed to heat sanitary hot water in a five-person household?

For a family of five people, 1 or 2 panels are needed, depending on the equipment which has been installed.
