Velux solar hot water systems can also be supplied with a number of optional extras, this will allow you flexibility to meet any unique requirements of your development.  Please contact your authorised Velux merchant if you wish to place an order for any of the items detailed below.

Flexible Flow and Return Pipes

The standard package provides these in ten metre lengths, however as optional extras you can purchase them in additional lenghts of 15m and 20m.  Arriving pre-insulated, they are capable of handling temperatures ranging from + 175°C down to 40°C. 

Immersion Heater

An immersion heater is an electrical element that heats up the water in the tank.  If you do not have the benefit of a gas or solid fuel boiler you can install an immersion heater into the tank for your auxiliary hot water.  It can also be used as back up heating for your water.

Filling Pump

Velux reccommend using a motorised pump when filling the solar circuit to ensure that all air pockets are removed.  The filling pump has the capacity to hold 50 litres of fluid.  The filling pump station has a large opening for pouring and mixing the solar fluid and it comes with two connecting hoses.  The strong pump with high flow ensures trouble free filling and pressurising. To help with storage and ease of transport, it is supplied on a wheeled frame.
