Solar plumbing diagrams showing how Solartwin is so easy to install...

Why is Solartwin's revolutionary new freeze-tolerant solar water heating system is so easy to install? Three solar panel plumbing diagrams follow. The first shows a conventional low pressure hot water system - with no solar panels. The next two diagrams show two very different solar installations. The conventional solar system is complicated! By contrast, the last diagram simply shows how Solartwin requires very little extra plumbing, takes up very little space in the house and is quick and easy to install.

1. Conventional low pressure hot water system with no solar

Basic plumbing for a normal low pressure hot water system - no solar

2. Conventional solar thermal system with pre-heat & antifreeze

Conventional solar system with pre-heat & antifreeze

This is one of several "traditional solar" plumbing options used in conventional (indirect) solar water heating systems.
It consumes a lot of space, takes longer to install and is expensive.

3. The Solartwin solar panel system

The Solartwin system is simply a 2.8 square metre (approx) solar water heating collector panel on the roof, plus an "intelligent" solar powered water pump and two strong, thin, flexible supply pipes.
From the outside, Solartwin looks like most conventional solar water heating panels: a black sheet of metal in a double glazed box. Like all solar water heaters, this absorbs solar energy and heats up.
Because the Solartwin system is freeze-tolerant, it now collects the heat using ordinary water, rather than antifreeze. Also, because it uses a photovoltaic (solar electric) panel to power the pump, the Solartwin system is totally solar.
The pump responds intelligently to reduced levels of sunlight by pumping slower. As a result, unlike most systems, it provides roughly the same water temperature increase all the time, even if is sunny or overcast.
It delivers the hot water directly into your existing hot water storage cylinder along simple to install, flexible pipes. The solar hot water floats on top of the colder water in the storage cylinder, waiting to leave first, when you want to use it.
Installing Solartwin is simple and relatively cheap. As you can see it requires minimal plumbing.
Solartwin installation also requires fewer technical skills. Only a single full skill is required in the installer: the skill of working on a roof. The need for plumbing skills is minimised although not completely removed since two simple "tee" connections need to be made to your existing plumbing. The remainder of the plumbing involves simply laying and clipping flexible pipes. No mains electrical skills are needed whatsoever because the system runs on low voltage solar electricity.

Solartwin offers minimum disruption when installing, and then is as equally easy to un-install and load in a van when moving house.
