The Sioux M Series water heater has been a best seller from Sioux for over 50 years.

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.
