The Heat Transfer Fluid

The Backbone of Hydronic Heating Systems
We are your trusted authority on hydronic heat transfer fluid for residential and commercial heating systems, which serves as the essential foundation of hydronic heating.
This fluid circulates within your hot water system but is often overlooked in terms of maintenance. It plays a crucial role in distributing heat throughout your home or building.
Over time, as it deteriorates, it can impact not only the heating efficiency but also damage fittings, valves, and other components—leading to potentially steep repair costs.
We offer comprehensive testing, maintenance, and cleaning services for this fluid, including effective bacteria removal solutions.
Testing & Maintenance
To maintain optimal fluid health, it’s important to conduct annual tests on the heat transfer fluid. These assessments reveal vital information regarding contamination levels, debris presence, pH balance, and freeze protection effectiveness within the system.
Based on the results of these evaluations, we can recommend appropriate maintenance solutions such as corrosion treatments, inhibitors, filtration enhancements, additional freeze protections, or bacteria elimination.
We offer all these services to ensure your heat transfer fluid remains in good condition and functions efficiently.
You can conveniently purchase your lab analysis online or through our boiler maintenance service.
Hydronic Heating Filtration

System Cleaning
Utilizing a top-notch sidestream filter is the best approach to keep your heat transfer fluid clean. These filters effectively eliminate sediment, contaminants, and tiny debris particles.
They are also crucial for our service that targets bacteria removal. Every hydronic heating system requires a sidestream filter assembly; you can easily purchase a replacement or a new installation directly from our online store.
Ensure your fluid stays pristine by investing in a high-quality sidestream filter assembly.

Hydronic Heating Bacteria
Bacteria Removal
When bacteria is present in the hydronic heat transfer fluid, it needs to be eliminated. This type of bacteria consumes both fresh water and freeze protection/glycol.
Flushing is ineffective since the bacteria adheres to the interior surfaces of the system and cannot be dislodged by this method. Given access to fresh water or new freeze protection/glycol, it will flourish and grow denser over time.
Our specialized service utilizes a unique treatment designed to eradicate the bacteria, which is then effectively removed from the system using a sidestream filter.

If you suspect bacterial contamination in your system, please reach out promptly for a quote on proper removal services.
Hydronic Heating Bacteria
What it Can Look Like
Bacteria in a hydronic heating system can vary significantly in terms of severity, ranging from mild brown to dense black. This buildup may emit a strong odor and possess a sticky consistency.
If not addressed appropriately, over time it can thicken to the point of clogging zone valves and boiler heat exchangers. Such conditions might damage pumps and lead to exceptionally high repair costs.

Hydronic Heating Freeze Protection

Preventing Ruptures & Flooding
Imagine the peace of mind that comes with knowing your hydronic heating system is fortified against the unpredictable chill of winter!
By adding freeze protection glycol to your home or building, you’re not just making a smart choice; you’re embracing a proactive approach to safeguarding your comfort and investment.
Our expert team specializes in integrating this essential fluid into any hydronic heating setup—whether it’s warming up cozy indoor spaces or ensuring outdoor snow melt systems run smoothly.
Ruptured Pipes
What it Can Look Like
Hydronic heating pipes may freeze if a window or door is left ajar. However, freezing can also occur in other locations where cold air seeps into the home or building, like beneath patio doors or windows, through uninsulated exterior walls, or even within uninsulated ceiling or flooring areas.
Additionally, what happens when the heating system malfunctions? Without heat circulating through the pipes, it becomes more likely for the fluid to freeze.
Once the pipes are frozen and the fluid expands upon freezing, it can cause ruptures in the pipes; later, when they thaw out, this leads to flooding.
Order Your Freeze Protection
We meticulously size and assess your piping system to determine the precise amount of heat transfer glycol needed, injecting a protective shield throughout your entire network.
With our rigorous testing protocols, we ensure that every drop meets the necessary freeze protection standards, giving you confidence even if your primary heating source falters.
Embrace worry-free winters and say goodbye to costly repairs; with our freeze protection service for hydronic heating, you can enjoy uninterrupted warmth all season long!
