A new way to think about solar energy

Willis Solasyphon

The Willis Solasyphon uses the sun's magical (and free) rays to provide your home with hot water within minutes

Our clever clogs device doesn’t rely on nasty fossil fuels for energy, so while you’re boiling your water, you won’t be boiling the planet! And, you’ll save up to 30% of the installation costs of a similar solar cylinder because the Solasyphon is fitted to your existing hot water storage cylinder.

It is vital that the renewable energy industry rises to the challenges presented by global warming and identifies new and innovative ways of delivering cost effective methods of harnessing and delivering renewable energy solutions to every household at an affordable price.

Installer benefits

No replacement cylinder required

The Willis Solasyphon can be connected to the existing hot water cylinder with two simple connections. This is quicker, cheaper and much more environmentally friendly than the alternative.

Delivers solar heating water direct

The unique and innovative feature of the Willis Solasyphon is the way in which it delivers solar heated water directly to the top of the existing water hot water cylinder where it stratifies ready for use at a useable temperature.

Produces hot water regardless of weather

In marginal or intermittent conditions such as are common in the northern hemisphere, particularly in Autumn, Winter and Spring the Willis Solasyphon will produce useable hot water in a way no other system can at present. One hours sunshine will produce one hours worth of hot water at a useable temperature.

Easy installation

Fitting a Willis Solasyphon to an existing system is quick and easy to install and minimises any possibility of upsetting the existing plumbing system that can occur when you are replacing the existing cylinder with a new solar cylinder.

Eco-friendly

The Willis Solasyphon is much more environmentally friendly than conventional twin coil solar cylinder technology due to the fact that the Syphon is fitted to the existing water heating system, therefore reducing the carbon footprint created by installing a new solar cylinder.
