Velux Solar Hot Water Tanks
Exceptional design, maximum efficiency

Velux solar tanks are manufactured from sheet steel.  Any part of the tank that comes into direct contact with water is protected against corrosion, bacteria and lime-scale deposits by an enviromentally friendly enamel coating.  This coating has been tested by WRc-NSF in accordance with BS6920 section 2.6.

Minimum heat loss is assured by the use of CFC-free foam insulation, ensuring optimal solar energy storage, The tank also features a unique control system that operates the pump to ensure maximum solar gain from the collectors.

Velux solar tanks are easy to connect to existing heating systems.

Velux Solar Tank key features:

High system efficiency and attractive design
Optimal temperature stratification
Easy installation due to a pre aligned pump and control unit
Easy commissioning due to optimised factory settings

Vented systems rely on the water being fed into the cylinder and kept under pressure via a gravity fed header tank typically sited in the loft.  When the water in the cylinder is heated it expands and the expanded water is taken up and into the header tank.

Unvented systems are fed and pressurised with water direct from the mains.  The expansion and contraction of the water when it is heated and cooled is controlled by an expansion vessel fitted to the cylinder.

Unique controls and optimum connectivity

The controls on the velux hot water storage tank are uniquely designed to operate the pump to maximise solar gain from the collectors.

The controller has been designed with many features and components that are highly adaptable for future additions to the system, or indeed emerging solar technology. 

Straightforward installation and servicing.

The Velux tanks are very easy to install and to service.  A full manual for connecting and commissioning the tank is supplied with the system.  The tank should only be assembled and installed by a competent tradesman.
