Boiler Heaters

Wattco offers a wide variety of process heating equipment to our customers. We manufacture boiler heaters that suit many different sizes and dimensions that customers need. If a boiler has a flanged heater that need to be replaced, Wattco can replicate the model you currently have from practically any manufacturer and have your boiler system up and running in a matter of hours. Boiler heaters come in a variety of different flange sizes and lengths. The two common models are rounded flanges and square flanges. The length of the boiler heater is highly correlated to the length that is available within your boiler. If all the major variables are known (ie. Wattage, Voltage, Length and Flange size), Wattco can replicate the model you have in no time.

These industrial heaters are used in many facilities for comfort heating, laundry services, and kitchen services. The nature of the facility’s operations will indicate whether the boiler system is steam generating or if hot water system is used. Industrial water heater systems typically heat water up to 230 degrees Fahrenheit. The operating pressure for hot water systems is approximately 30 psi to 125 psig (hydrostatic).

There are many different types of steam and hot water boilers. Low-pressure steam boilers are limited to 15 psig and are predominantly used in common heating practices such as comfort heating. High-pressure boilers are used for more intense applications and can have up to 1000 psig.

Electric boilers are extremely popular as they are considered the most efficient method of heating water or steam and they are clean, quiet and easy to install. Because there are no carbon emissions, these industrial heating solutions have very low maintenance costs with easily replaceable electrical heating elements (flange heaters). Government regulated bodies are enforcing more often, the use of electric boilers to meet carbon emission standards that are being enforced as a result of the carbon footprints of fossile fuels. In areas where the cost of electric power is favorable, electric heating is considered the best choice as it offers power ranges of 5KW up to 3,000 KW of output power.
