Sioux M Series Water Heaters

Sioux M Series

The Sioux M Series water heater has been a best seller from Sioux for over 50 years. The Sioux M Series’ three-pass coil design is superior to alternative heat transfer methods, yielding simple, long-lasting performance which reduces fuel consumption, saving you money. Designed as modular units, the Sioux M Series water heaters allow you to make a minimal investment to start, with the option to expand your system as your operation grows. The heaters come pre-plumbed and pre-wired and have a small footprint, making them simple to install. Just connect the Sioux water heater to the required utilities and you’re ready to go.

If you require a tank with your water heater, please see our HWP or PWP models or add one of our Tank Package to your water heater.
