Solar thermal systems work on the basis of transforming solar irradiation into heat (solar gain) which is used to provide free hot water or space heating. As solar irradiation is absorbed from both direct sunlight (40%) and diffuse sunlight (60%), a solar thermal system is perfectly suited to the British climate as it will produce energy, even on cloudy and cold days.

An Envirosol Solar thermal system is capable of providing up to 60% of a properties annual domestic hot water requirements and is the easiest renewable technology to integrate with an existing heating system. Creating this type of hybrid heating system allows the solar thermal system to work independently if there is sufficient solar gain, but then has the flexibility to work in conjunction with another heat source when solar gain is reduced.

Firebird’s Envirosol™ CPK7210-N Flat Panel Collector is one of the most efficient collectors in the world, with an optical efficiency of 81.8%. One of the unique features of the Envirosol™ CPK7210-N is that the collector base is extruded from a single aluminium sheet thus removing the need for welds, joints or gluing at the corners.

Renewable heating technologies require a dedicated hot water storage cylinder with a larger coil to allow maximum heat transfer of renewable energy into the stored water.

The Envirocyl range of hot water storage cylinders have been specifically designed for use with Firebird Envirosol solar thermal systems. Featuring purpose-designed coils which have the optimum surface area to water flow ratio, the cylinders offer a highly efficient way of providing space heating and domestic hot water.
