Stage 1 of a solar installation – the panels:

If required, we will arrange for scaffolding to be erected. This allows for a safe and efficient installation of the solar panel(s) on your roof. Once the scaffold is in place we install the panels on your roof.

Stage 2 of a solar installation – the cylinder:

We will most likely replace your hot water cylinder with a high efficiency twin coil cylinder. The solar panel will transfer the heat the bottom of the cylinder. When required, your boiler will top up the heat in the solar cylinder therefore ensuring always enough hot water.

In certain cases it is possible to retain the existing hot water cylinder and fit what is a called a retro coil in thee place of your existing immersion heater. This system is less efficient but does have the benefit of saving the old cylinder and reducing the overall cost.

Stage 3 of a solar installation – the pump station:

We install a solar pump station to transfer the heat collected from the solar panel into the hot water cylinder coil. This is controlled by an electronic variable controller that switches on the pump only when the temperature of the panel is greater than that of the water cylinder. The pump station is connected to an expansion vessel to accommodate the increase in volume when the antifreeze expand. There is also a discharge vessel for the safety pressure relief valve to discharge the antifreeze in event of over pressurisation.

Stage 4:

Using a special high pressure solar flushing / filtering / filling pump we fill the system with high temperature corrosion inhibited antifreeze, pressurize

and commission the system.
