Pump Station

The Velux solar hot water system has a multi-functional solar thermal pump station which has been designed specifically for high temperatures.  It features variable speed settings, a built in flow indicator, and dual gravity brakes to prevent back flow of solar fluid. To ease installation, the pump station can be either tank or wall mounted.  The pump station comes complete with bespoke insulation cover for thermal efficiency and portection.  It also has a built in pressure guage and safety pressure release valve for the solar curcuit.

Programmer

The Velux solar hot water system has a user friendly, universal solar system controller.  It has preset controls and clearly shows the varying temperatures between the solar collectors and the hot water tank.  It can also indicate the accumulated hours of solar thermal gain.  This programmer has the capacity to control multi solar circuits including space heating, and can be set to a variety of different languages.  It incorpates a fault diagnostic programme should any problem occur.

Flexible Flow and Return Pipes

These flexible stainless steel tubes connect the solar collectors to the tank, which allows quick and simple installation of the flow and return pipes.  Arriving pre-insulated, they are capable of handling temperatures ranging from + 175°C down to 40°C.  The standard package provides these in ten metre lengths, although there are other sizes available.

Underfelt Sealing Collar

Self adhesive underfelt collars are supplied to ensure a perfect fit around the flexable flow and return pipes when they pass through the roofing membrane.  these will assist with both the thermal performance and air tightness of the property.

Safety Mixer Valve

A temperature sensitive safety mixer valve is supplied with every solar package.  this ensures that only the desired temperature of hot water is delivered to the taps.  It can be set to temperatures ranging from 35°C to 65°C

Micro Air Bubble Separator

As with all closed curcuits, it is possible for small amounts of air to become trapped during installation.  A unique micro air bubble separator is supplied with all solar packages to facilitat the removal of this trapped air.  The separator is self adjusting and requires no maintenance.  The unique valve mechanism is quaranteed not to leak.  As solar circuits can reach extremly high temperatures, the separator is designed to withstand temperatures up to 180°C.
