On the other side of the heat exchanger is another tube where the heating fluid enters and picks up the heat from the plates and then travels out to the heating system. This allows you to add glycol to the radiant system without it mixing with your domestic water. A Radiantec system that uses a heat exchanger is called an Indirect System.
6) Small thermal expansion coefficient Heat exchanger made of superalloy Cr25Ni20 series, popularly used in all kinds of radiant tubes in annealing furnace.

The Heat Exchanger System DIY Radiant Floor Heating A heat exchanger system using antifreeze can protect the radiant heating system down to -60 below zero. But the tradeoff is efficiency. Transferring heat from one medium to another (in this case, from potable water to antifreeze via the heat exchanger) costs BTUs.
A heat exchanger is a number of flat stainless-steel plates pressed together. There is a tube on one side where the warm water from the heater travels through and heats the plates. On the other side of the heat exchanger is another tube where the heating fluid enters and picks up the heat from the plates.
