Axiom Feeder Tanks for Hydronic Heating Systems

Maintaining a hydronic heating system can be challenging, especially with issues like fluid loss and potential contamination.

However, with the introduction of Axiom feeder tanks, you can enhance the performance and longevity of your system.

Find out how these innovative tanks can simplify maintenance and save you money in the long run.

Fluid Levels Drop

A hydronic heating system uses a boiler to heat water that is then circulated through radiators, or pipes under the floor.

Ideally, such a system would be totally closed and never need any fluid added to it, but in practice, this is not possible. Over time, some water will always be lost to evaporation (and perhaps leaks).

In addition, any volume of water will have some air dissolved in it. As the water circulates, these dissolved gases are eventually liberated and bled from the system, with an attendant drop in the fluid level.

Accordingly, these systems eventually need to be topped up.

 

Solutions

There are two methods for maintaining the fill of a hydronic heating system.

Many boiler feeds are just connected to the municipal water supply; this requires the use of an automatic water valve with a backflow prevention mechanism, regulating the water level inside the system while preventing that water from flowing back out.

It’s crucial that this backflow prevention device be checked annually to ensure there is no cross-contamination between the water you drink and the treated water inside the system.

The second method is to use an Axiom feeder tank to store a mixture of glycol and water for the boiler, allowing a total separation of the heating system from the potable water supply. Routine service of one of these tanks just entails stocking it with fluid and maintaining the optimal water/glycol ratio.

Why A Water-Glycol Mix?

The use of inhibited glycol in your heating system prevents freezing, reduces corrosion by minimizing oxygen levels in the water, and improves the heat transfer properties of the system. These are essentially all the same reasons we use antifreeze in our cars; it means better efficiency, longer life, and fewer breakdowns.

Better Over The Long Term

There are a couple of advantages to using a glycol feed tank versus a municipal water feed. It allows for easier testing of the glycol levels, which should be no lower than 30% and no higher than 50%. It’s also a simple retrofit, and if you compare its installed cost to the annual maintenance cost of backflow prevention, the Axiom tank can pay for itself in about five years, with a life expectancy of about fifteen years.

Why Axiom Feeder Tanks Have Good Flood Prevention

Axiom feeder tanks are designed to offer several advantages that contribute to their effective flood prevention capabilities.

Here’s a detailed explanation of the key features and benefits:

1. Closed System Design:

  • Explanation: Axiom feeder tanks operate within a closed system, which means they are not directly connected to the municipal water supply. This separation ensures that there is no continuous influx of water that could lead to flooding in case of a malfunction.
  • Benefit: The closed system minimizes the risk of water leaks or overflows that could cause flooding.

2. Controlled Fluid Levels:

  • Explanation: The tanks are equipped with mechanisms to monitor and control fluid levels precisely. They maintain the optimal water-glycol mixture without the need for constant manual intervention.
  • Benefit: By automatically maintaining proper fluid levels, these tanks prevent overfilling and potential spillage, thereby reducing the risk of flooding.

3. Glycol-Water Mixture:

  • Explanation: The use of a glycol-water mixture instead of plain water reduces the chances of freezing, which can cause pipes to burst and lead to flooding. Glycol also minimizes the formation of air pockets, which can lead to pressure build-up and leaks.
  • Benefit: By using this mixture, the system operates more smoothly and safely, with less risk of sudden pressure changes that could result in flooding.

    1. Hi Gerald,

      No, if it is inhibited glycol you can add in right out of the pail

      You can always call us if your are unsure.

      Take Care!
