A solar tank is a critical part of your solar hot water system. The type and size of solar tank you need is often a poorly understood part of a system, mainly because there are so many variables to it. We use the SolarStor Hot Water Tanks manufacture in the USA. Our Solar Storage tank are the only UL certified water tank that has both a top an bottom internal heat exchanger as well as a middle 4.5 Kw back up heating element.
This allows a many more options for solar hot water. With this arrangement you can have both pre heat solar tank or a supplemental. The supplemental tank allow you to use only one tank and during periods of poor solar, the electric element supplements the solar energy. This also means that when investing in solar hot water you no longer need to purchase two tanks, making the payback that much better.
Commercial Solar Water Tanks - Closed Loop
A closed loop commercial solar water heating system can be used to directly heat the domestic hot water. The standards require that the materials used in a closed loop heating system meet ANSE plumbing standards. Because large pressurized tanks with these standards are costly, we deign more affordable system using multiple smaller water heating tanks run in parallel. In this way we can offer solar water heating system with larger storage capacities that perform the same or better than a single large tank system. It also makes transporting and installation easier as the smaller tanks (119 gallons) are more manageable. These tank designs can use internal or external heat exchangers to transfer the solar energy to the potable water.
Commercial Solar Water Tanks - Open Loop A commercial solar water tank is similar to a residential solar water tank except that it much larger. We offer Cocoon solar tanks that are available in 8 different sizes. The large tanks are made of 6-8" thick insulation and tied together with aluminum braces and steel studs. The advantage of this type of water storage tank is that it is modular and can be easily shipped anywhere in the world at a fraction of the cost. Its supper insulation value makes it ideal for solar thermal storage where tank heat loss can rob a systems performance. An open loop tank is not pressurized and and as such is not connected to the main water supply. Instead heat exchangers are used to more the stored heat from the storage tank to the heating source.
