  6. How does it work? Solar Thermal acts as an upgrade to your existing heating system, producing hot water by How Solar Thermal works harnessing renewable energy from the sun. The 1. Cold water enters the system from system’s “collectors” absorb solar energy and mains supply transfer that into thermal energy to be used in a hot water cylinder or thermal store. We supply 2. the collector is warm enough the pump If closed-loop solar thermal systems. This means will be activated by the solar controller the fluid that circulates from the panel to the 3. olar fluid is then pumped round the S hot water cylinder never touches the water that collector, heated by solar energy comes out of your tap. It works like this: 4. his fluid then passes in to a cylinder T heating up the water via a coil 5. required a second coil brings up the If water to the pre-set temperature via an existing boiler 6. ot water is now available through H Solar Thermal - domestic hot the taps water system Solar Thermal - Domestic Hot Water System 6 Hot Water, Underfloor Heating Central Heating 3 Boiler Flat Panel or 5 4 Evacuated Tube Pump Collector !

  7. Solar Thermal technology Every Solar Thermal system is made up of a Solar collectors solar panel (also known as a solar collector), There are two types of solar thermal panel: Flat plate a hot water cylinder, a pump and a controller. flat-plate collectors and evacuated-tube Flat-plate collectors consist of dark-coloured absorber You’ll also need a boiler or immersion heater collectors. Evacuated-tube collectors are known plate. The plates are enclosed within a glazed, insulated box to back up the system. for being the more efficient of the two, as they that behaves like a mini greenhouse to retain heat within can produce slightly higher yields in autumn the collector. Solar cylinder and spring. However, over the course of a year The hot water cylinder installed will have a the amount of hot water both types of collector • More versatile. Provides versatility as it can be mounted ‘twin coil’ heating system. The lower coil is produce is very similar, so we’d advise you to horizontally, vertically, on the roof and in the roof heated by your solar collector while the upper consider the pros and cons of each before making a decision. • Glazed flat-plate collectors are good value, last a long coil is heated through your existing boiler. If you time and need very little maintenance have a combi boiler we’ll install a thermal store (a small hot water cylinder to store the water • More robust design and less likely to overheat heated by the panels) plus a specially designed CombiSOL valve, which regulates the inlet • good option if your home is a new build or is having A water temperature. a new roof, as they can be integrated with the roof itself. This gives a neater look – similar to Velux windows – and saves money on other roofing materials Pump and controller The speed of the pump is managed by the controller. It reacts to the temperature of the fluid in the solar collector and the water in the Evacuator tubes cylinder to automatically determine the rate at which the fluid is pumped around the system. Evacuator tubes consist of rows of parallel tubes, each containing a glass thermal absorber. During production, air is evacuated from the tubes allowing it to reach higher temperature at all light levels. • Evacuated-tube collectors have a higher efficiency than flat-plate collectors, so they may be a good option if you have a small amount of space • They can also be mounted in almost any orientation, from a flat roof to a wall. Even if you already have PV panels covering your roof, you may still be able to fix a solar thermal collector to a south-facing wall • Easy to repair. Failed tubes can just be replaced without any major disruption 12 13
