Circulation Heaters – Ideal for Clean Water Heating Applications

The rise of technology has left lasting impressions on the world of heating with some of newest heaters making use of technology to help heating performances. One such heater is known as the circulation heater.

These heaters are also known as inline heaters and unlike most other heaters, are designed for the purpose of indirect heating only. The most common application is to use them as circulation water heaters. This is mainly because warm water is required in a number of different industrial applications as well as industrial cleaning and washing operations.

Practical Usage Of Circulation Water Heaters

One key aspect about electric heaters in general is that their performance often depends on the heating material or sheath material used. As far as their use for heating water is concerned, there are a number of different sheath materials that users can choose from. Which one to choose will depend on the size of the vessel where the water is being heated, the power ratings, etc.

When making use of these heaters in relation to clean water, it is important that a pump is used for the transportation of the fluid inside the circulation heater. As the water is pumped inside the cirelectric heating cold climatesculation heater, it is heated by the heating element along the way. To make best use of the resources, it is important that the inlet for the liquid is close to the actual heating element in the circulation heater. This ensures a shorter overall path that the liquid must take, which means less required heating space and greater efficiency.

During the movement of the water from one nozzle that brings water into the circulation heater to the other nozzle that sends water out of the circulation heater, the heating takes place. So that when the water comes out through the other nozzle, its temperature is higher than when it entered.

Typically, there are two ways that these heaters can be mounted:

  • Horizontally
  • Vertically

Useful Features of Circulation Water Heaters

There are a number of useful features found in circulation water heaters. One such feature is the presence of the drain valve which can, in case of an emergency or unnecessary blockage of water, control the desired temperature of the water in the heater. On top of that, most heaters are packed with thermocouple probes which are able to control the desired temperature of water.

Circulations heaters also have a number of different terminal boxes. As we are discussing circulation heaters for water, it is likely that a single terminal box is sufficient.


Using circulation heaters in the heating of water for industrial applications is something that is starting to gain momentum. Here is a low down on some of the benefits that make circulation heaters such a valuable acquisition.

  • Efficient heat transfer
  • Can be used with a wide range of fluids other than water should the need arise
  • Easy to maintain
  • Easy to Mount

Circulation heaters have an important role to play in the future of water heating.
