Envirosun Solar TS

Envirosun solar hot water cylinders provide the benefits of solar water heating — by harnessing the sun’s energy and converting it into hot water, a solar heater reduces your household’s greenhouse gas emissions, saves you money on energy bills and adds value to your home. Envirosun (sister brand to Enviroheat in solar water heating) takes these benefits one step further, with a real commitment to the environment and to you.

Features of the TS system:

• Tank and collectors roof-mounted as a single, integrated unit
• Maximum solar efficiency with no power input
• Technologically-advanced safety and control systems
• Closed circuit for maximum solar collector freeze and fouling protection (THX only)
• Superior durability, reliability and cost-effectiveness

Thermo-siphon flow is a natural process that drives the weather, currents in the ocean and water heated in a pot. It occurs as a result of the density difference between warm and cool water – warm-water, because it is less dense, naturally rises and displaces denser cool-water. The same process drives both the TS and THX solar water heaters.

The storage tank sits on the roof immediately above and nestled against the solar collectors. This reduces the amount of pipework between the tanks and collectors and keeps heat loss down. It also means that as fluid is heated in the solar collectors, it can naturally rise up to the cooler storage tank. Provided the fluid in the collectors is hotter than the base of the storage tank, circulation continues. As the collector temperature approaches that of the tank, circulation stops – automatically. The whole process occurs without the need for any external power to operate pumps or valves – and the flow is naturally optimised.

With the TS systems, hot water from the collectors flows to the middle of the storage tank, and displaces cooler water lying in the bottom of the tank. This in turn flows down into the collectors to be heated. For the THX system, the hot collector fluid enters the jacket chamber around the storage tank, transfers its heat to the water within the tank and returns to the solar collectors for reheating.
