Pumped Solar System

For the UK, the pumped system is the most popular, followed by the Drain Back type system. Systems which can be added to combi boilers are making advances, and are a consideration in certain circumstances.

Pumped systems allow for the excepted practice of installing the solar collector high on the roof, with the solar HW storage system at a lower level. The fluid medium (an anti-freeze glycol mix) is circulated by pump and regulated by the controller. Heat is collected from the sun, and transferred to the HW cylinder.

Drain Back Solar System

The drain back unit requires a little more thought when designing, but addresses the issue of when the HW storage is satisfied, fluid is drained away from the collector when the pump turns off. Where fluid sits in the collector in a normal pumped system, during the off/satisfied period, extremely high temperatures can be experienced.

Thermo-Siphon Solar System

Thermo-siphon and Freeze tolerant are generally associated with warmer climates.

Combi Boiler add-on Solar System

Combi Boiler systems have an unvented cylinder added to store solar heat gains. The boiler adds top-up heat as required. (Not all combi boilers are compatible with this method, please check with the boiler manufacturer.)
