Stainless steel resists the corrosion that kills glass-lined tanks, which is why Eco-King backs these for life. Indirect models pair with any boiler or air to water heat pump to provide unparalleled hot water production. European quality and superior performance at a great price.
The King series of Eco-King Indirect Water Tanks are the number one tank sold in Canada for a reason. The tank shell and heat exchanger coil is constructed of 444 Stainless Steel. Our tanks have been on the market for years with some of the best hot water production rates due to our large length and diameter heat exchanger coil(s). Also, King tanks offer a limited lifetime warranty that gives a guarantee to installers and homeowners alike to trust the choice to use our product!
The new King series has three models with capacity ranges from 42 to 119usg.
All stainless steel buffer tank with no coil. Perfect for storing large volumes of potable water or buffer tanks for heating
Our traditional single coil stainless indirect now including T&P relief valve, drain valve installed and included tank sensor
Replaces our double coil tanks. Similar except the PLUS series double coil is internal with only one connection externally. Easier to install then our older models, but with EVEN MORE hot water production!

As a contractor we installed several brands over the years. We are glad we found Eco-King, well made product, easy to install and reliable. A+++

My Eco-King Indirect tank was leaking due to no expansion tank on the side. King company recommended Mahdi who is an excellent technician and repaired it. I’m highly satisfied with his job and recommend Eco-King and Mahdi to others.
