Installing Solar Thermal Systems

An investment in solar will typically return over double its cost in lower electricity bills over your systems lifetime.

Fitting a solar system to your home will almost certainly increase the value of your property and can be a important factor in helping sell your property.

Solar is a long-term investment.The thermal output of Viessmann solar collectors remains high for over 20 years, protecting your investment.

Complete solar installations with panels, hot water cylinder and system controller (or even a new matching boiler) are available.

Installation stages

Stage 1: A free technical survey is carried out to ensure you have the best combination of products to suit your needs

Stage 2: We arrange a convenient date and time for installation

Stage 3: We fit the panel(s) to your roof:

Stage 4: We replace your hot water cylinder with a high efficiency twin coil cylinder. The solar panel will heat the bottom of the tank and your boiler will top up the heat if required.

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

Stage 5: We install a pump to circulate the heat collected from the solar panel into the hot water cylinder. This is controlled by an electronic controller that switches on the pump only when the temperature of the panel is greater than that of the water cylinder.

Stage 6: 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.

Stage 7: The sun comes out and you start enjoying free hot water (and reducing your carbon foot print!)
