What fluid is used in radiant floor heating?
A typical radiant heating/boiler system uses tap water as it must have a connection to a water supply for make up water. Also a propylene glycol solution is used for freeze protection. Another thing that must be considered is the water temperatures used.
Can you put antifreeze in home heating?
Do not use automotive antifreeze in heating boiler systems. Some of these can clog the boiler heat exchanger.
What type of glycol is used in heating systems?
ethylene glycol
There are two basic types of glycols used in HVAC systems, propylene glycol and ethylene glycol. Both of these fluids have similar freeze protection and heat transfer characteristics with the main difference being that propylene glycol has a lower toxicity level.
How do I add antifreeze to my boiler?
Step 2 – Add Antifreeze
- Close the water valve near the boiler that feeds house water into your boiler system.
- Find a location for the antifreeze to be forced into system, possibly the boiler drain valve.
- Begin to pump antifreeze into the boiler.
- Add enough antifreeze to pressurize the system to 12-15 psi.
Do you put antifreeze in hot water tank?
The antifreeze won’t hurt the tank, but don’t forget to flush it out before firing it up next spring. This will help you get the antifreeze flushed out without messing up your existing winterize job on the rest of the plumbing.
How long does glycol last in a heating system?
Choosing Glycol for Hydronic Heating Systems While most non-inhibited glycol products have a three to five-year lifespan, pre-mixed Sentinel X500 glycol can provide up to 20 years of service before needing replacement.
Is glycol a antifreeze?
What is antifreeze? A glycol-based fluid made primarily from ethylene glycol or propylene glycol, antifreeze is one of the components of the fluid used in the cooling system of your car.
What kind of anti freeze do you use in a heating system?
Usually heating system antifreeze products use propylene glycol. As we explain here, there are some good reasons for using a non-toxic anti-freeze in heating boilers.
How much anti freeze do you need for radiant floor heating?
Radiant Floor Company includes this information on your worksheet. Determine what percentage of anti-freeze to water mixture is recommended by the manufacture of the heat source. Ratios can vary. Some manufacturers recommend anywhere from 20%, 30 % anti-freeze, other’s 50%.
Do you need to use an antifreeze heat exchanger?
Even the need for freeze protection is often overrated because a radiant system stores so much heat in the mass of the home. An example of a Radiant & baseboard / fan coil design. A heat exchanger system using antifreeze can protect the radiant heating system down to -60 below zero. But the tradeoff is efficiency.
When to add antifreeze to hydronic heating systems?
Every once in a while it becomes necessary to use non-toxic antifreeze in a hydronic heating system. The reasons for using non-toxic glycol vary from job to job.

What does Hercules cryo Tek 1 Gal antifreeze do?
Curbside pickup available. Hercules Cryo-Tek 1 Gal. Antifreeze, with a triple protection inhibitor system, helps protect against mineral deposits and sedimentation in hydronic heating and closed loop systems, solar heating systems, radiant heat and general plumbing systems. This non-flammable, odorless liquid is also non-toxic.
