1 World Solar

To get the most from your solar system you need an appropriately sized hot water cylinder to store as much of the energy your solar panels collect as possible. This can be achieved by adding an additional pre-heat cylinder which stores just the solar heated water. This cylinder then feeds your existing tank. In practice it is often cheaper and less disruptive just to replace the existing cylinder with a larger solar twin coil model. Please see our cylinders page to see the wide range we have available.

There are a number of alternatives such as the Willis Solar Syphon which is a good solution if the cylinder cannot be changed. However, in most cases, we feel that if you are going to make the investment in a solar thermal system its best not to let its performance down by compromising on the cylinder.
