42 RENEWA B L E E N E R G I E S Solving a problem with the UK’s weather HPM takes a closer step-by-step look at the installation of a Grant Sahara solar thermal Solar thermal technology operates with both direct and diffused sunlight and so is perfectly designed for the UK’s varied weather, achieving as much as a 70% saving in hot water heating costs. For ease of ordering, Grant provides its solar thermal products in kit form, complete with all the required components. State-of-the-art solar controllers automate the operation of the solar thermal system making ownership easy and stress free. The solar pump station has been designed with the installer in mind, incorporating a high efficiency pump, air eliminator and manual bleed screw for rapid air removal from the system. Keeping maintenance to a minimum Sahara solar collectors have an efficiency of 82.6% and incorporate self-cleaning glass to keep maintenance to a minimum. With many new and existing heating installations involving mains pressure combination boilers, a simple, cost effective solution to integrate these two technologies is a must. Grant’s team has also developed the CombiSOL, which enables installers to easily integrate a combination boiler with a solar thermal system. In short, it controls the outlet temperature of stored water produced by the solar thermal collectors and directs the flow either straight to the hot water outlet or via the combi boiler. The simple six-step installation system for an outdoor swimming pool Outdoor pool to be heated with Grant solar thermal Job done and the family have a warm pool took place at a domestic property where an outdoor swimming pool needed to be heated. Step one The ground is prepped and a concrete base put down ready for the solar collectors. Step two Collector flat-roof A-frames are put together and placed into position on the base. Step three Grant Sahara collectors are fixed onto the A-frame. There is also the option to install these using either an ‘on-roof’ or ‘in-roof’ mounting system. Step four Pump housing is installed under the pool decking ready to house the solar components. Step five The pump station and pool heat exchanger are plumbed in and the expansion vessel connected. Step six The Grant GSX1 Solar controller is wired inside the house. enquiry number 130 www.hpmmag.com August 2016 Step one Step two Step three Step four Step five Step six Before After “The solar pump station has been designed with the installer in mind”
