Thermal stores are a clever way of eliminating the need for a cold water storage tank and providing mains pressure hot water. Heat energy is stored in the cylinder and a highly efficient heat exchanger transfers the energy into the incoming cold water as it is required. As the output water is not stored, it is an ideal way of minimising legionella risks. Thermal stores usually come complete with thermostatic blender valves as well as additional inputs for solar and wood burning stoves. The size of a thermal store usually needs to be larger than a typical cylinder and they benefit from a higher operating temperature. A typical 3/4 bed house should consider a 200l store. They are ideal for use with solar panels.

An innovative way of retaining your existing cylinder!

When considering a solar system, powered by evacuated tubes or flat plate systems, it is very important to review the cylinder currently in use. Guidelines suggest that at least 60litres of water be allocated for exclusively solar use, and this usually means installing a new and larger cylinder. We are experts with many hundreds of solar thermal installations under our belt. We are able to design the most appropriate system using only the very best solar panels for home use currently available.

This cylinder would be designed for solar use and usually contain an additional coil in the lower section.

Sometimes the property already has the benefit of a sufficient sized and good condition cylinder, so it becomes frustrating to remove and replace a perf ectly good tank.

This is where the Willis Solar syphon comes in. The syphon sits alongside the existing tank and transfers its heat to the top of the tank, ready for immediate use.

The solar syphon works with both unvented and vented systems.

An accumulator is basically a large heat store. Sized from 500l to anything up to 5000 litres or more they are used to absorb and store energy for later use. They can be put underground or in outside storage but of course need high levels of insulation in order to retain the energy created.

One application for the use of an accumulator is to reduce peak energy requirements from an incoming energy source.

Wood / pellet burning stoves, and ground source heat pumps can benefit from the use of these.

Another application is for use as a buffer vessel for a swimming pool. By storing heat using the solar pump, it can be transferred to th pool when the pool pump is in filtration mode. The benefit of such a system lies in the fact that if the pool pump is always used to extract the energy, it can result in more than necessary use of the pool pump.
