Titanium Heat Exchangers

Swimming pool heat pumps are equipped with titanium heat exchangers to provide maximum heat transfer.

Titanium heat exchangers utilize rifled titanium, in a coaxial, or “tube in tube” configuration. The rifled titanium tubing inside the heat exchanger swirls the water and refrigerant efficiently. The expanded surface area of the rifled titanium maximizes its contact with the refrigerant and water, providing heat transfer at a greater rate. And since it’s titanium it will never corrode or wear out. The results are more heat for less money, making a pool heater with a Titanium Heat Exchanger the most efficient pool heat pump in the world.

Uncoated bare titanium heat exchanger tubing eliminate ALL corrosion and maximize heat transfer efficiency. That’s one of the reasons why heat pumps have the highest COP (Coefficient of Performance) in the industry.

Why Titanium

Titanium is IMPERVIOUS to corrosion, which means it will never corrode or wear out.

Because Titanium is so expensive, heat pump manufacturers have looked at various alternative heat exchanger tubing materials and designs to try to lower their manufacturing costs. Some use only one wrap of titanium tubing in their heat exchanger which drastically reduces efficiency (COP).

Another potential solution is to use less expensive copper tubing just like the gas heaters do. After all, copper is a very good heat conductor.

The problem with bare copper is that it will rapidly corrode in high chlorine pool water and a green copper oxide coating will form which is a very poor heat conductor. If corrosion continues then the tube wall will leak and ruin the heat pump system.

To protect the copper some manufacturers have looked at various plastic coatings, however, plastic coatings are just as bad as copper oxide at heat conduction. They insolate the hot refrigerant gas inside the tube from the water outside, lower heat transfer efficiency. This increases the compressor watts and lowers your COP.

In fact, all plastic materials have heat transfer coefficient less than 1% of copper or titanium metal, so even a thin coating of any type of plastic will significantly decrease heat transfer and efficiency. Only the thinnest coating can even hope to come close to bare Titanium in heat conduction and even then the thinner it is the more likely it is to have a small pinhole or incomplete coverage of the vulnerable copper tube underneath.

Why Use Twisted and Spiral Tubes?

Titanium heat exchangers are used to move heat from one area to another. Pool water is swirled around a twisted tube (water simply passes over round tube in a straight line). The action of the water increases heat transfer and acts as a self cleaning mechanism, eliminating scale and corrosion on the surface of the tube.

The net result is significantly lower operating costs.
