SunEarth SU80HE-1 & SU120HE-1 Double-Wall Solar Heat Exchange Tanks
80/120 Gallon Model Classes • Double-Wall Heat Exchanger • Residential Indirect Solar Thermal Storage
The SunEarth HE Series solar storage tanks are designed for indirect solar water-heating systems where heat must be transferred from a solar collector circuit into stored domestic hot water.
Unlike conventional tanks that rely on an immersed internal coil, the SunEarth HE design incorporates copper heat exchange tubing wrapped around and secured to the storage tank. This arrangement transfers thermal energy through the tank wall without mixing solar heat-transfer fluid with stored potable water.
The heat exchanger incorporates a vented double-wall configuration that provides an additional protective barrier between the solar collector fluid and domestic hot water.
Designed for residential indirect solar thermal applications, the tanks include supplemental electric water heating, corrosion-resistant tank lining, anode protection, and accessible plumbing connections.
SunEarth identifies a 6-year limited warranty for the SU HE tank family, subject to the applicable manufacturer warranty statement.

The mini ultra boiler i purchased was built very strong and worked great after being installed.
Price was right
This is a great unit for anyone who is on a well!!
Great pump and great price. I actually ordered from a human being and they were great
Very nice expansion tank. Mine is a 16 gallon. Has feet so it will sit on the floor next to your boiler and doesn’t have to be mounted on the wall.
It’s sturdy enough to support your Air Separator, Pressure Regulator and Backflow Preventer.
I recently installed my new 29kw BTH Ultra boiler and so far I am really impressed.
We live in an old 2 story brick farmhouse built in 1814! This unit replaced an Outdoor Wood Boiler with a 750 gallon tank. It was about 30 years old and last winter the tank rusted thru and busted.
We have 11 cast iron “American Radiators” and they heat the house well.
The BTH will heat all the water to 150 degrees in about an hour and we don’t have to build a fire and wait hours.
The most impressive part is the Outdoor Temperature sensor. When it’s not that cold outside, the unit doesn’t turn on all the elements at once and slowly heats the water which saves a lot of electricity in the warmer months!
I’m looking forward to see how well it does when the temperature drops between 0-30 and it snows and I don’t have to go outside several times a day and load wood. I’m confident the Ghost Rider will perform!
Thanks.
The boiler works great easy install. But the tech support we got hold of was in French so not a lot of help.manual was easy to follow on wiring
Easy purchase - exactly what I needed
Plumber was very happy with it. So are we.
I’ve been using Everflux for some years now and it’s simply the best there is.
Excellent product for descaling tankless water heater.
Once again, great quick service
Good go,, 👍👍👍
Great service. Happy to find the products I needed.
Great place to order from. No complaints.
