SHIPPING:
We get very good LTL (Less Than Truckload) rates when shipping solar water heaters. Aside from great pricing, we are able to shippalletsat amuch better price than our competitors.
Please contact us with your desired system size, zip code, whether you need a liftgate to remove the pallet from the 18-wheeler (solar units can often be broken down inside the truck and carried down piece by piece with no issues) and whether it is delivering to a residential address or a business address with a commercial zoning by the city. Most of our carriers provide free residential delivery, but this must be declared prior to shipping to get the free service.
Important Information About LTL Shipments: Prior to signing the delivery receipt, you must inspect your merchandise for damage. If you sign the delivery receipt without declaring any known damage, we will be unable to file a claim with the carrier and unable to replace broken merchandise. Signing the delivery receipt is your waivor of right to a damage claim. For the solar tubes, we send approximately 30% extra tubes in case some tubes break. We will only do a freight claim if the damage exceeds the amount of spare tubes provided. Any spare tubes which make it to you undamaged may be kept as spares.

50m (164 ft)35m (115 ft)*Note: Listed tank heights do not include the mounting feet. Mounting feet add an additional 6.8cm (2.7\") of additional height. Be sure to allow for adequate space to connect piping to the top and bottom of the tank. The feet are required to allow adequate spacing for connecting to the bottom drain port. Why use a solar water heater tank?Active solar water heaters utilize an antifreeze as the working fluid in the system. This fluid carries the heat collector from the sun to a tank stored in a different location. In order to exchange heat to the water within the tank, a heat exchanger is required. Our solar water tanks come with a built-in copper heat exchanger, so the working fluid can simply pass through the coil, thus heating the water inside.
If a tank without a built-in heat exchanger is to be used, an external heat exchanger must be utilized to exchange the heat to the water. This will also require a 2nd circulation pump, as the water inside of the tank will need to circulate through the heat exchanger and back into the tank in order to collect heat from the working fluid, which is also circulating through the heat exchanger. Use of a solar water heater tank with a built-in heat exchanger minimizes needed parts to successfully operate a system and reduces heat loss to the outside Environment.
Stainless Steel Tanks Are Better than Vitreous Enamel TanksOur tanks are made of food grade stainless steel layered with a galvanized steel shell on the outside for increased strength against high pressures. Stainless steel is superior in solar water heating applications because it can handle the very high temperatures produced by solar water heaters, has excellent corrosion resistance and can handle the constant high pressure resulting from constant heating throughout the day.
Vitreous enamel tanks are made of carbon steel and utilize a glass lining to protect the steel from corrosion. Unfortunately, these cheaper style tanks cannot handle the constant pressure in solar water heater systems. When the water temperature rises to 70°C or greater, which is typical for a solar water heater system, there is high risk of cracking of the glass lining due to excessive expansion and sticking to the carbon steel. Once cracks have formed, the carbon steel may rapidly corrode due to exposure to the water, which often results in premature failure.
Copper Heat Exchange CoilsEvery tank comes with a copper coil in the bottom of the tank for heating by the solar loop. The coil extends from where the ports enter and down to the bottom of the tank so that the entire tank of water can be heated fully by the solar loop.
Dual coil tanks come with a 2nd coil installed on the top. This coil can be used for many different things, separate from the solar system. Some examples include:
1. If a user has a a boiler, the working fluid can pass through this coil as backup heating of the tank when temperatures run below the minimum temperature.
2. The top coil can be used for recovery of heat for another system such as radiant floor heating or a radiator somewhere else in the system where using the solar loop fluid directly in the radiator is not preferred.
Electric Back-up heatingAll tanks come equipped with a 220v electric backup heating element. The tank come with a standard screw-in 1\" port which accepts most standard water heating elements. Should the user wish to install a different heating element, it can easily be swapped out. The tank has a built-in thermostat for operation of the element independent of the solar system. The maximum amperage this thermostat can handle is 25 amps. The maximum the on/off switch on the element housing is 16 amps. If a higher amperage is to be used, simply do not wire to the switch and only use the thermostat and your household breaker for turning the element\'s power off or on.
Our solar water heater controller may also be used for operating the electric backup heating element in conjunction with a relay. The controller can activate the relay which provides power to the element. The advantage to using our controller is that it can be set to only run during certain times of the day so that there will not be any backup heating when water will not be in use such as during 3am. For small households which use water at only specific times, this may offer an advantage.
The electric backup heating element is considered optional. If it is not hooked up, the tank will still operate normally without backup heating. Users may wish to leave the element disconnected if
Note on Dual Coil Tanks: The upper coil is in the middle of the tank. On the smaller diameter tanks, users may find it a little difficult to install a long water heating element into the tank as it can collide with the coil. Since these tanks use electric water heating elements as backup heating only, a large element is usually not necessary so this is often not a with several automatic control and protection devices such as thermostatic control, over-temperature protector, pressure protection device and one way valve.
Magnesium Rod
Our tanks come with a magnesium anode rod. Magnesium rods work as a sacrificial anode. It will corrode before the other metals in the tank due to it being less noble than the stainless steel and galvanic outer shell. This is especially useful in helping to prevent pitting of the stainless steel. Magnesium rods are the best in soft water conditions. If your area has very hard water, it may be beneficial to consider an aluminum rod instead. Replace the magnesium rod every 3-5 to help preserve the tank for as long as possible.
Casing
The casing of the tank is made of a zinc-galvanized board with static powder coating and a baked finish which resists rust, ultraviolet rays and decoloration from long-term use.
Large Applications
Several tanks can be installed in parallel when accommodating larger systems with higher water demand. Streams of water can be distributed equally.
Operation RecommendationsPressure
The water supply pressure should not be higher than 100 psi. In the case of higher water supply pressure, install a water pressure regulator valve. It is best to run the tank at 60 psi or less. Since the sun heats the tank often, a lot of water will be lost through the T/P valve from rising pressure. Use expansion tanks as necessary to prevent water/heat loss.
Additional Recommended AccessoriesThermostatic Mixing Valve. Since the sun can be variant based on weather and the seasons, it is best to install an in-line thermostatic mixing valve to control the outlet temperature of the hot water from the tank. When the tank is extra hot, it will mix cold water with the hot water to make the perfect desired temperature. This offers safety protection from especially children in the household, but more importantly, helps conserve heat that is wasted in the pipes from un-used water. It\'s better to mix automatically at the tank than manually at the faucet!
WarrantyOur stainless steel water tanks come with a 5 year manufacturer\'s warranty against manufacturing defects.
