Introducing new King Series Tanks

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.

✓Tanks with stainless steel construction that are pickled and passivated for superior corrosion resistance and no need to use an anode
✓Indirect models pair with Supreme and Ultimate boilers as well as air to water heat pumps
✓Electric models for gas-free homes

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.

I’m highly satisfied with his job and recommend Eco-King

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.
