Wattco inline heaters are designed to enhance the performance of a regular immersion heater, heating up liquid solutions while maximizing efficiency. These units are ideally suited for heating pressurized fluids including water, oil, steam, and various gases.
If you’re considering an inline heater for your industrial process application, we’ve prepared the following questions below to help you expedite the selection process and determine if a Wattco inline heater is the most suitable option for your needs.
When we receive requests from prospective clients we ask a concise yet elaborate set of questions to qualify the clients needs and set up realistic expectation for how the inline heater will be procured, how it will interface and interact with the rest of the production process at your facility, and what sort of maintenance and repair requirements can be expected.
With Wattco, procuring production process equipment is a consultative process. We work with you to exchange knowledge and ideas to get you the optimal solution for your heating needs.
Below we’ve listed the primary considerations and questions you should be prepared to answer when asking for a quote. To save time and make the procurement process as efficient as possible for whomever is in charge of procurement, it helps to have answers to such questions on hand when contacting us.
If you require detailed specification about our inline circulation heaters, consult our online inline heater brochure as a convenient and easy reference. Also bear in mind that in the majority we can get back to you with a quote within 24 hours, getting you the information you need to make a decision.
1. What solution would the inline heater be heating?
Several characteristics of an inline heater’s construction depend on the state and properties of the medium being heated. Among the most important considerations are whether the medium is corrosive and its viscosity.
Providing Wattco with specific information on the medium being heated allows us to recommend construction materials which won’t react adversely with the medium and will provide optimal heat transfer for improved production efficiency. See the table below for specific details about which sheath material is appropriate depending on the medium it is exposed to and application it is intended for.
2. What is the required flow rate of the solution?
In order to make a sensible recommendation for the heater’s pump and construction material we require detailed information on the required flow rate. This information is also required to make recommendations for the the type of inlet and outlet nozzles and operating pressure.
3. What is your required wattage for the inline heater?
Knowing the wattage required for your applications helps us select the proper power supply and heating element – the heating element’s construction material must be selected based on the watt density and the speed and level of temperature to be attained.
4. What voltage is required for your inline heater?
Voltage is another consideration regarding the unit’s power supply and material of the element.
5. What phase does the heater need to be wired for?
Single-phase distribution is most commonly used for electrical loads like heating or lighting, but exceptions do exist. If your application requires a different form of electrical power distribution be sure to let your Wattco representative know.
6. Will the heater be deployed outdoors or indoors?
The environment in which an inline heater is meant to operate determines the type and degree of insulation as well as the wattage density requirements, since viscosity increases as temperature decreases. Be sure to disclose if the heater will be moved from interior to exterior operations. If the heater is intended for an outdoor application it must be built to withstand the prevailing climate in your region in order to function at full operational capacity for the optimal length of time.
7. What is the ambient temperature in the place where the heater will be operating?
Ambient temperature refers to the temperature of the area immediately surrounding equipment, in this case an inline heater. Ambient temperature informs our recommendation of construction material, insulation, and heating element material. If you need a heater for outdoor use, please provide us with the average ambient temperature as accurately as possible.
8. Is the unit going to be operating in a hazardous environment?
Knowing whether or not the inline heater will be required to operate in a hazardous environment is among the most crucial questions. Please specify in as great a level of detail as possible what the adverse conditions are. These conditions can range from inclement weather to radioactivity or toxic atmosphere.
9. What temperature does the solution which the Inline heater will be heating need to reach?
The required temperature lets us know what voltage and watt density the heater needs to have, both of which are factors to consider when selecting the material for the element.
10. How quickly does the solution need to achieve the required temperature?
Time constraint allows us to select the appropriate electric phase, watt density, and construction material. Flow rate also factors into this parameter.
11. Do you need the heater to be skid mounted and mobile?
If you require a heater which can be moved around the facility it can be mounted on a skid for ease of movement.
12. Do you require a control panel for your Inline heater?
Wattco control panels enable fast, responsive control of various variables of the heater including temperature, flow rate, and pressure. Our control panels can be customized to fit a range of custom requirements and can be fitted with NEMA enclosures which protect the internal control components from virtually any hazards, contaminants, or adverse conditions.
Inline circulation heaters are all-in-one circulation heaters constructed of an immersion heating element mounted inside an insulated tank.
Consider the following factors to select the proper heater for your application. If you require recommendations or further clarification regarding these factors please contact a Wattco representative.
– The operating temperature the inline heater must operate at?
– The watt density of the heater’s heating element.
– The construction material of the inline heater’s sheath. The material depends on whether or not the heater will be exposed to corrosive or non-corrosive contaminants in the environment. If there are corrosive contaminants exposed to the heater please also consider:
– The temperature of the corrodent.
– How much aeration the corrodent receives.
– The velocity of the corrodent.
Below we’ve listed the standard inline heater specifications to allow you to conveniently refer to them when making a purchasing decision.

– If your heater has a voltage exceeding 240 V., a current over 30 amps, or a three phase supply, the thermostat is used as pilot only and is therefore not factory wired to other elements.
Wattco’s line of inline here are designed for long-lasting, high-efficiency performance. Depending on the details of your industrial application you will need a heating components of various construction materials. Refer to the diagram to the right for a detailed account of inline heater construction.
Generally speaking, the heat from an electric inline heater leaves the heater instead of passing to the steam or liquid exchanger. Be aware that even the heating element is in proper contact with the solution being heated, the heating element’s sheath temperature will continue to increase until it is close to equal with the heat being transferred in the process.
Bear in mind that due to the laws of thermodynamics, heaters with low watt density tend to last longer than heaters which have high watt densities. This phenomena is especially common with liquids which are stagnant or very viscous. For this reason and others, low-density heaters tend to be more expensive than heaters which have high watt density.
