Solar Water Tanks - Solar Storage Tanks

SolarStor Solar Water Tanks are North Americas only complete solar water tanks and are UL and CSA certified. Unlike other tank manufactures SolStor tanks come complete with two large internal heat exchangers and a back up 4.5 Kw electric element ALL In One Tank! This tank is suitable for all forms of solar heating systems including solar hot water heaters, solar home heating and solar pools and hot tubs! With this tank you can easily expand your solar heating system at any time with out new equipment!
Solar water tanks are used in solar heating packages to act as buffer tanks.When the sun is shinning, the water will be heated in the solar storage tank for later use, most commonly in the evening. Most solar water tanks contain a heat exchanger to separate the potable water from the solar heating solution (Water/Glycol), and have a great insulation value that can retain the heat for day. The SolStor tank has a rated heat loss of less than .8 degrees F/ Hour!
There are 3 kinds of solar water tank systems used in North America:
  • Solar Pre-Heat Tank
  • Solar Combo Electric Tank
  • Solar Dual Heat Exchanger Tank
SolarStor Water tanks are North America's Only 3-In-one solar water tanks.
3-In-One Solar Tank
Solar Pre Heat with existing heater Solar Heater with electric back up Solar Water with 2nd Heating zone
Pre Heat water for use with existing water heater
Replaces existing tank comes with 4.5 Kw back up
Top Heat Exchanger can be used for 2nd home heating loop
SolarStor tanks can offer 3 types of Heating configuration for now or Future

The 1st and most common solar heating tank configuration is a Solar pre-heat tank for hot water heating. This type of solar heating system is used in homes with an existing water heater (electric, oil, gas, tank-less). The pre heat tank stores the solar heated hot water which is then drawn into the main tank when the hot water faucets are open. This type of system use the large 14 ft2 internal heat exchanger to heat the potable water in the tank. The pre heat tank heats the other wise cold ground water before it enters the normal water tank. In this way ground or main line water of approx 35 F can be preheated to say 120 + degrees before entering the primary heating tank. If the heating tank is set to 130 degrees it only needs to raise the water 10 degrees instead of the 95 degrees it would have otherwise had to with out the solar pre heat tank.

The second type of solar water heating tank configuration is used as combo tank with solar and Electric. The combo tank uses the built in 14 ft2 heat exchange on the bottom of the tank and also uses the middle 4.5 Kw heater element as back up. The solar hot water is circulated through the solar loop and through the internal heat exchanger heating the water in the tank. The element will then add to, and top up, the tanks temperature to the desired setting. This type of system is great for new homes or replacement tanks. It is important to note that very few solar water tanks found in North America meet UL or CSA certification as a combo tank, as such most European or Asian manufactured solar tanks can not be used with potable (drinking water).SolarStor tanks are 100% UL listed and can be used in any solar application in US or Canada.

The final type of solar storage tank configuration is suited for dual solar heating applications and uses both the top and bottom heat exchanger with/without the electric element supplement. In this tank configuration, the bottom heat exchanger heats the water from the bottom, The upper heat exchanger loop is found in the hottest part of the solar tank (hot water rises). This hot water surrounds the upper coil which then transfers this heat to a second heating zone such as radiant floor loop or to a furnace air to water heat exchanger. This type of solar storage tank configuration is designed for both heating applications and/or domestic hot water. In this configuration the customer can still use the electric heating element as it is include on all tanks. This allows customers to use SolarStor tanks as a complete Hydronic Heating System Boiler, however unlike other boiler, this is supplemented by free solar energy!
