How to Apply Antifreeze to a Hydronic Heating System

What You'll Need
Propylene glycol
Water tank
Non toxic materials
Reroute piping

A hydronic heating system helps heat commercial buildings. While antifreezes are necessary especially in the winter months for minimizing corrosion in the pipes.



Step 1-Use Union Carbide for Burst Protection

Using union carbide helps in ‘bad’ water situations and you can buy pre-blended glycol for the reason.


Step 2-Mix Propylene Barrel

Mix 30% propylene barrel in hydronic heating before pumping the drained water is helpful.


Step 3-Use Antifreeze

These are spaces like crawl spaces and radiant on-grade slabs, depending on the quantity of fluid the system can hold.


Step 4-Use Glycol in Extreme Temperatures

Glycol helps prevent leakage from the freeze where the temperatures dip below -20 degrees Fahrenheit.


Step 5-Hydrometer is Required

Using a hydrometer helps you to get into the system through a diaphragm pump for cleansing water cooled condensers.


Step 6-Analyze the Water Content

Add the right amount of antifreeze by analyzing the water content considering thermal conductivity, maintenance, wastes etc.


Step 7-Apply the Antifreeze

Apply this considering the heat design temperature of the place, nontoxic antifreeze, system water content ratio etc.


Step 8-Reroute Piping

This prevents freezing, cuts down on heat transfer and maintenance costs.

Using antifreeze in residential areas should be avoided. Glycol is recommended as it is non-toxic.
