Swimming pool heating with pool heat exchanger
What is a pool heat exchanger?
The pool heat exchanger is a method of heating the water in your pool.
The heating system used with the pool heat exchanger is gas, since it uses the gas that is burned to heat a heat exchange mechanism with the water.
Heat exchangers: suitable for small pools
Heat exchangers are ideal for small pools
In the same way, it should be noted that it is a type of heating suitable for small pools, or as an auxiliary heating system that has up to 150 m³.
When can pool heat exchangers be used?
Use of pool heat exchangers
Likewise, Heat Exchangers are used, for example, natural gas from the boiler, propane gas or fuel oil to heat the pool water.
A water circuit is established in which the pool water passes through the boiler, is heated, and subsequently returns to the pool.
Different types of pool heat exchanger

How a tubular heat exchanger works
Tubular heat exchanger operation
Composition of shell and tube heat exchangers
The shell and tube heat exchangers They are composed of cylindrical tubes, mounted within a cylindrical casing, with the axis of the tubes parallel to the axis of the casing. One fluid circulates inside the tubes, and the other circulates outside (shell-side fluid).
The tubular heat exchangers They consist of two independent pressure chambers: the casing and the tubular bundle.
Two media flow through these chambers in such a way that when there is a temperature difference between them, heat is exchanged without the media mixing.
Tubular heat exchanger calculation
Sizing of a tubular heat exchanger
To perform the sizing of a heat exchanger It is necessary to have certain starting data, such as the process flow, initial and final temperatureAs well as physical properties of the product.
An essential factor for calculation and sizing of a tubular heat exchanger is to be able to characterize the behavior of the product in a reliable and precise way.
, through laboratory tests, where the main properties of the product can be determined, such as:
- Density.
- Specific heat.
- Thermal conductivity.
- Viscosity.

Tubular heat exchanger parts
What are the basic components of shell and tube heat exchanger?
The basic components of a tubular heat exchanger are:
heat exchanger tubular bundle
What is a tube bundle?
- The tubular bundle is the set of tubes that provide the heat transfer surface between the fluid that circulates inside and the fluid that circulates through the casing. This set of tubes is where the product to be heated is located.
tubular plate
- The tubular plate is a metal plate that has been perforated or drilled, where the tubes that form the tubular heat exchanger are housed, which are fixed by expansion or welding. If extra protection against leaks is required, a double tubular plate can be used.
Housing and connections
- The casing is the envelope of the second fluid or secondary fluid. The casing is generally circular in section and is made of a steel plate formed into a cylindrical shape and longitudinally welded. The housing has connections for the inlet and outlet of the secondary fluid.
baffles
- The main purpose of the baffles is to control the general direction of casing side flow.

Types of tubular heat exchangers
Tubular heat exchanger models
Depending on its design, the nature of the product and the available space at the destination facility, the tubular heat exchanger can be grouped into 3 main groups:
The tube-in-tube heat exchanger
- First of all, there is this type also known as double tube heat exchanger, which is formed by two concentric tubes of different diameters, where the product circulates through the inner tube and the service does so through the space that exists between both tubes.
Annular Space Heat Exchanger
- On the other hand, there is another variety of exchanger that is made up of three or four concentric tubes. The product flows through the central annular space while the service flows through the outer and inner channels.
The multitubular heat exchanger
- Likewise, there is also a model that is made up of a tubular bundle inside a casing. The product flows through the inner tubes, while the service flows through the outer channel.
