SIZING CRITERIA
RADIASOL HEATS WATER USING ITS FULL LOAD THERMAL MASS
((NOT A STORAGE TANK LIKE TRADITIONAL SYSTEMS)
It is compliant to European standard EN 12976 (factory-made systems).
In order to properly size the system and calculate solar cover You should consider the annual average
daily production of hot water at 45 °C made by RADIASOL models in a sunny day, expressed in MJ or KW
(see table).
THE THERMAL POWER OF RADIASOL IS USED FOR VARIOUS TYPES OF APPLICATIONS:
Production of hot water for houses, hotels, hospitals, motorway service stations, sports centres,
industry.
Benefits
Good yield in all seasons with return on investment in a short time.
Simpler, smaller sized systems.
No maintenance needed.
Thermal flywheel combined with the heat pump both for home heating and hot water.
Benefits
RADIASOL greatly increases performance of heat pumps and can provide consistent performance even
in winter, when heat pumps are less powerful.
Integration with radiant heating systems, civil and industrial.
Benefits
RADIASOL’s thermal performance allows a drastic reduction of depreciation times for this type of
installations.
Production of electricity in combination with low temperature heat pumps (70/120 °C).
Benefits
Production of fully eco-friendly electricity.
Maximum energy safety with very low maintenance costs.
Data provided represent an indication only and refers to RADIASOL D models facing South (North if below the equator) in
climate zone E, with 35/40° inclination.
