Introduction Our Vacuum Tube Solar Collectors are ideal for heating your swimming pool or hot tub. SRCC certified for Canada and the US, the Heating Manifold can provide the thermal energy you need to keep you swimming pool's water warm when combined with our Titanium Heat Exchangers. Our Stainless Steel Corrugated Pipes create a loop with the Exchanger, Manifolds and a Solar Pump Station which circulates the fluid around the Solar Hose. Our Kits can work in extreme Canadian Winter to heat your spa, by using glycol as a heat transfer fluid in closed loop solar piping.
