Energy Panel

Heat Merchants have partnered with Energy Panel to offer the most advance technology in Thermodynamic Solar Systems for both residential and commercial projects. The Heat Merchants technical design team can guide you through the range of options and work with you to design your heating and hot water system featuring the latest renewable energy technology.

Energy Panel are dedicated to the development and manufacture of thermodynamic solar systems and other high energy efficiency equipment. Their Thermodynamic systems have been manufactured according to a variety of European quality standards and are supported by SEAI, European Heat Pump Association and more.

Thermodynamic Solar Technology

The thermodynamic solar systems use heat pump technology supported by solar energy to generate domestic hot water and heating by capturing solar and environmental energy to heat water in a efficient way, with very low energy consumption compared to conventional systems.

Why thermodynamic solar panels are different?

  • Obtain hot water under any atmospheric condition, functioning at night time as well as in wet or windy weather
  • Works continuously 24 hours a day 365 days per year under all weather conditions
  • Without glass or electrical components
  • Ventilation and de-icing unnecessary
  • Don’t need maintenance or cleaning
  • Dirtiness does not affect the output of the panel

How does Solar Thermodynamic Heat Pump Technology Work?

A refrigerant fluid at low temperature (that could be less than 0ºC) circulates in the interior of the thermodynamic panel. The fluid captures the incidental solar radiation in the panel as well as other environmental energy. The thermodynamic cycle condenser transfers the heat to the water. The ecological refrigerant R134-A or R407C, which enters into the panel at a negative temperature, runs through the closed circuit situated in the interior of the panel. The difference in temperature provoked by external agents such as the sun, rain or the wind guarantees the gasification of the fluid.

The compressor sucks the heated gas and reduces its volume, raising its temperature and transmitting it to the water circuit through a heat exchanger, managing to obtain domestic hot water up to 55 or 65°C. At high pressure and after having transfer a large part of its heat to the condenser, the refrigerant fluid arrives at the expansion valve again in liquid phase. Here the pressure is reduced which means the fluid is in condition to enter into the panels once again. The valve regulates the outflow depending on its temperature. Like this, the refrigerant will be sent again, in the form of micro drops, through the dehydrated copper piping to the panels, where it will be compressed once again, and the cycle will be repeated until the desired temperature is reached.

Thermoboil E –Series

The Thermboil E Series is a heat pump system supported by solar energy capture. It is characterised by its incorporation of a thermodynamic solar panel that generates a high performance thanks to the collection of incidental solar radiation as well as the energy contained in the external environment (air, rain, etc).

Thermoboil E & I Series

The Thermboil E+I Series is a unique technology capable of harvesting energy in two ways: combining a thermodynamic solar panel which collects solar radiation and external environmental energy and an inner heat exchanger that extracts energy from indoors. In this way, it assures a continuous output even with low temperatures.

Thermoboil I Series

The Thermboil I Series is characterized by incorporating an inner heat exchanger that takes advantage of indoors energy to heat domestic hot water (DHW).

Thermboil Wall-Hung

A heat pump of reduced dimensions designed to be installed on the wall, allowing its architectural integration in places with limited space.

Thermoboil Rapid Heating

The Thermboil RH line is especially designed to satisfy greater volumes of DHW through one compact equipment that accelerates the heating time due to its greater thermodynamic power.

Thermoboil Modular

The Thermboil Mural is composed of two differents blocks, one is the the water accumulator and the another include the thermodynamic system. It work exactly in the same way as Thermboil. The thermodynamic unit contains the compressor, expansion valve, boiler and all the elements for regulation and control. This unit is connected to the condenser of the accumulator.

Green E-Pack Suitable for Retro-fitting

An innovative solution to cover the demand of domestic hot water in properties and houses that already have a cylinder installed. The system is extremely easy to install, as it connects the water tanks to the flow and return connectors providing hot water continuously.

Green E-Pack I Suitable for Retro-fitting

This is a compact unit which includes all the elements of the heat pump as well as the inner heat exchanger. The built-in fan uses the air from inside of the living space and transmits it to the water pumped to the storage cylinder. The output air can be conducted to the outside via ducts.
