Water Heaters

How should I prepare my water(s) for upcoming water heater season?
Please see our Preseason Checklist
Is there a burner that can operate on natural gas, propane and/or diesel/fuel oil?
Yes, Sioux offers a combination burner that will fire on all three different fuel types. This adds a great deal of versatility to any operation.
How long does it take before hot water is produced from a Sioux water heater?
Within 2-3 minutes, a Sioux water heater will provide outlet water at its maximum temperature.
Does Sioux offer a direct-fired type of water heater?
Yes, the Sioux Hybrid Water Heater is a direct contact water heater and coil-type of heater all in one. The coil section provides excellent combustion of the fuel and allows for recirculating water from a storage tank, and the exhaust gases pass through heat transfer media to capture the remaining heat from the flue gases. 
On 2 and 3 million BTU systems, do all burners have to be running at a time?
No, depending on demand, each burner section can be ran independently.
