Types of Circulation Heaters
 

Electric circulation heaters

A circulating electric heater is a device for heating the flowing medium by means of forced convection. It consists of an immersion type electric heater and a pressure vessel, in operation, the flowing medium is pumped into the heating chamber for heating by the pump, and the heated medium flows out from the other end of the heater. This type of heater is characterised by small volume, large heating power and high thermal efficiency, with the maximum working temperature up to 600℃ and pressure resistance up to 20MPa.

Electric water heater

Water circulation electric heater is a kind of efficient and environment-friendly heating equipment, which reduces the direct consumption of electricity by transferring heat through circulating water and avoids the problem of over-drying of air. Its core components are usually made of high quality copper materials with good thermal conductivity and corrosion resistance to ensure the durability and efficient operation of the equipment. Electric water-circulating heaters are usually available in wall-mounted and vertical versions, suitable for modern domestic heating systems.

Q: How does a circulating heater work?

A: Circulation Heater Construction
The heater unit is either a flanged or a screw-plug immersion heater and it sits inside a pressure vessel or the body of a pipe. The heating unit has inlet and outlet valves which allow fluid to pass through the tank unit and reach the desired temperature.

Q: What is the difference between circulation heater and immersion heater?

A: Circulation heaters are simply an immersion heater placed into a vessel. Fluid/Gas travels into the vessel containing the heater, down the elements picking up the heat, then out of the opposite end. An electric process circulation heater is designed to heat fluid as it circulates through a closed-loop system.

Q: How efficient are circulation heaters?

A: Circulation heaters, namely electric ones, are 100% energy-efficient due to their operation. They use a process known as electric resistance heating, which converts all of the heater's electric energy into heat. That heat then flows from the unit into a tank or room that needs it.

Q: Does a circulating block heater have a pump?

A: An active heating system that circulates coolant with an electric pump. Forced flow heaters warm the coolant and pump the coolant through the engine block providing uniform heat distribution.
