Warmflow Solar vacuum tube collectors The 360º absorber surface in each Warmflow Solar vacuum tube maximises the use of the sun s energy by catching the sun s rays from a wide angle as it passes from east to west during the day. The vacuum chamber between the inner and outer layers of glass minimises heat loss in a similar way to a thermos flask, meaning as much of the sun s energy as possible ends up where you want it - in your hot water. Because the losses are minimised, a Warmflow Solar vacuum tube system is capable of contributing significantly to the energy required for hot water production even during the winter, as long as the sun is shining. the way the heat pipe works installation benefits The Warmflow Solar vacuum tube manifold has the pipework connections off-the-top, rather than off-the-side, meaning multiple collectors can be positioned as close together as possible, maximising the use of available south-facing roof area. Because the Warmflow Solar vacuum tube kit is assembled on the roof each item can be lifted one at a time, so no heavy lifting is required. What s more, the system can be installed, filled and pressure tested without the tubes in place. All this work can therefore be done cold, minimising the risk of burns. The sun s energy is captured by a 360 o sputtered coating then absorbed into the heat pipe in the centre of the tube where it boils a heat transfer fluid. The vapour produced travels to the top of the heat pipe where the heat is transferred into the collector manifold. The cooled vapour then condenses and trickles to the bottom of the heat pipe to repeat the process. specifications Model Solar SHP20 Solar SHP30 Number of tubes 20 30 Absorber area 1.626 m 2 2.439 m 2 Collector L x W x H 2050 x 1400 x 154 mm 2050 x 2100 x 154 mm Assembled weight 66.5 kg 95.0 kg 0 0.762 0.764 a 1 (W/m 2 K) 2.12 1.63 a 2 (W/m 2 K) 0.0077 0.0143 Absorption 95% Emission 5% In a new build, if the property might not be occupied for some time, the tubes can be stored safely off site and fitted later. In the event that an individual tube might need to be replaced, this can be done easily without draining down the system. maximise the sun s 4

flat panel collectors Warmflow Solar s flat plat collectors feature a high performance laser welded absorber with selective coating and are encased in a deepdrawn, corrosion-resistant aluminium housing with 60mm of thermal insulation, minimising heat losses and maximising system performance. The absorber is protected by a layer of 3mm thermally pre-tensioned safety glass sealed with a one-piece EPDM seal. The collectors are assembled using an automated process during which a sealing force of over 200 tonnes is applied, ensuring the internal components are effectively shielding from the harmful effects of the weather and guaranteeing a long service life. specifications Model Solar SFP1 Absorber area 2.0 m 2 Collector L x W x H 2100 x 1100 x 110 mm Assembled weight 36 kg 0 0.712 a 1 (W/m 2 K) 3.50 a 2 (W/m 2 K) 0.0084 Absorption 95% Emission 5% The collector mounting system features an easy-to-install support frame, secured in place with either tiled roof or slate roof mounting brackets, and can be installed prior to fitting the panels, allowing the frame to be mounted at the time the roof is tiled and the panels to be safely stored off-site for installation and commissioning at a later date. Each collector features 4 connections, two off each side, allowing up to 10 collectors can be connected in series, side-by-side. The collectors are joined using specially-designed connectors to accommodate thermal expansion, thereby protecting the collectors from undue thermal stress. quality design with built-in reliability Weather Seal Circumferential EPDM profiled seal.

Warmflow Solar controls and accessories optional extras Most components necessary for the typical installation are included in our standard kits (page 7). All kit components are also available individually. Depending on the installation, the following accessories may be required: (SF10) (SEV18) (SVFK1) (SRF1) (SSRB20) (SSRB30) (SNTC1) (SFS1) Green solar fluid, 10 litres pre-mix 18 litre solar-rated expansion vessel Vessel connection kit Roof flashing Slate roof brackets (for 20-tube kit) Slate roof brackets (for 30-tube kit) NTC10K sensor (for temp-controlled secondary return) Solar filling station The continuous air separator within the Solar Dual-line Pump Station speeds the installation process by aiding in the removal of air from the system. It also helps maintain system performance by continuously separating air from the Solar fluid when in operation. 6bar pressure relief valve Continuous air separator Pressure gauge Temperature gauge High density insulating casing Wilo 3-speed circulating pump Flow indicator / regulator high-specification controller (SEV18) solar filling station In order to effectively remove all air from the system it must be filled using a filling station. The SFS1 from Warmflow Solar (pictured below) is the ideal solution. Measuring 39 x 32 x 78cm and weighing only 15kg, the unit has a fluid capacity of 25 litres and can deliver a maximum flow rate of 27 litres/min. The maximum pressure, for leak testing is 5 bar. The unit has a brass impeller for corrosion resistance and long life. (SRF1) (SFS1) Warmflow Solar s easy to use digital controller not only manages the solar collector, it also provides control over the back-up heat source (immersion heater or boiler) with a built-in programmer. Preset parameters provide frost and overheat protection, an anti-legionella function and a cylinder cooling function to help protect both the panel and cylinder. There are additional input/output channels to control other system components, such as a secondary pumped return circuit. By controlling the hot water pump (not supplied) via an additional pipe sensor (optional), the Warmflow Solar controller minimizes electrical power consumption and heat losses by only running the pump when required. This compares to a wasteful traditional system which runs the pump continuously whenever the time clock calls for hot water. warmflow green solar fluid Warmflow Green Solar Fluid is blended with high-tech inhibitors, especially designed for solar heating systems to provide effective corrosion and antifreeze protection and to maintain thermal efficiency. It is formulated to change colour from green to brown to alert the service engineer when the fluid needs to be replaced. Warmflow Green Solar Fluid is non-hazardous, non-toxic and bio-degradable - so it really is green. quality design with 6

Both cylinders in our range are twin-coil, so can be connected to a boiler for back-up. They are manufactured from high grade corrosion-resistant Duplex stainless steel and are unvented, meaning they operate at mains water pressure so can provide very high hot water flow rates - essential for an invigorating showering experience, or for fast-filling baths. Warmflow solar cylinders are highly insulated with 60mm of CFC/HCFC-free, zero ozone-depletion (ODP), fire-retardant insulation and are equipped with high heat transfer exchanger coils, meaning that they capture and store the sun s energy as efficiently as possible as well as allowing the boiler to operate at peak efficiently and for as short a time as possible when used as a back-up heat source. specifications Duplex stainless steel cylinder Backup coil Dual thermostat 3 kw immersion heater Dual thermostat Solar coil Model Capacity Weight full Height Diameter Heat up Recovery Standby loss TW250UV 255 litres 318 kg 1752 mm 577 mm 25 mins 19 mins 2.31 kwh/day TW300UV 305 litres 378 kg 2028 mm 577 mm 30 mins 22 mins 2.51 kwh/day built-in reliability 7
