Sunbank 40 Gallon Solar Water Heater – SRCC Certified – 30% Tax Credit

Because our 80 gallon system is out of stock, we will offer two 40 gallon systems for the price of one 80 gallon system. Contact us for a custom invoice. 

The Sunbank 40 gallon solar water heater is a complete passive solar water heating system that is easy to install, efficient, and affordable. It has many applications, from residential both on and off-grid, to any commercial application that requires hot water. It includes the tank, evacuated tube collectors, and bracket. The SB-40G is SRCC certified which makes it eligible for the federal tax credit (ending 2025) as well as local incentives for solar water heaters. It is the only solar water heater of its type that has the SRCC certification.

One important thing that distinguishes the SB-40G from its competitors is the 316L stainless steel tank, which is much more expensive to produce, much more corrosion resistant than 304 stainless steel, and will last much longer. We want the system to last for a long time because we know that the majority of the overall cost of the system is the installation cost. In addition to the stainless steel inner and outer tank, we have a highly corrosion resistant aluminum and stainless steel bracket. The system is heated by 15 evacuated tube, nickel-plated copper heat pipe collectors and can be installed as a pre-heater to your existing system or a stand alone heater with the built in 240V - 2400W heating element and controller accessory. The SB-40G has a standard 10 year warranty on the collectors and 1 year warranty on all other components of the system.

Back leg assembly for flat roof or ground mount sold separately. The best way to order is to send us an email or give us a call, with a short description of your project.
