  • I am confused about how to connect my Solar Speed Flex with the connectors provided.

    These pictorial instructions  should help you.

  • How can I easily estimate how much Solar Speed Flex to order?

    These schematics show the set up for one and for two solar thermal panels:

  • I am confused about the terms FLOW and RETURN pipes. Are they different?


    The flow pipe carries hot water from the solar thermal panel(s) to the cylinder. It is fitted with the temperature sensor cable which links to the digital controller.

    The return pipe is used elsewhere in the circuit and carries cold water.

  • Which size pipe should I use, DN12 or DN16?

    DN12 is recommended for a single solar thermal panel.

    DN16 is recommended for two or more solar thermal panels.

Suitable for fulfilling the hot water needs of a 3-5 bedroom household with 2-5 people.

Our modern solar water heating panels use the latest evacuated tube and heat-pipe technology to make them extremely efficient. They can convert 60% of the solar energy that falls on them into useful heat energy. They can operate in temperatures as cold as -35°C enabling them to contribute to water heating throughout the UK winter. There is no risk of frost damage and they are durable, and resistant to hail. During the summer they can provide 90-100% of your hot water needs. Averaged over the year they will provide ~50-70% of hot water required. Payback times and performance can be viewed here.

The panel frame and manifold are made of powder coated (anodised) aluminium, thus giving our panels excellent corrgenuine_tubeosion resistance and a high quality finish. The panels are manufactured to a high standard and are designed to last and look good on your roof for over 20 years. The roof fixings are stainless steel. All kits come with detailed instructions for installation and commissioning, and this is within the capabilities of most Do-It-Yourself enthusiasts.

All of our vacuum tubes are etched with our logo on the inside tube during manufacture, so you can be confident you are purchasing the genuine article.
