Glycol Floor Heating Systems

Rht hydronic fill purge system.

Glycol floor heating systems.

Does the glycol protect the metal in my systems. When added to water glycol lowers the freezing temperature of the resulting mixture ensuring that it remains liquid even during harsh winter weather. We also provide a master index to this topic or you can try the page top or bottom. Properties of propylene glycol used as an rv or heating boiler antifreeze and in other applications.

Since glycol has a lower specific heat than water higher concentrations of glycol in your closed loop water will reduce the heat carrying capacity of the system. The percentage of anti freeze propylene glycol is determined by the type of heat source on demand heater or tank type and by the guidelines listed on the anti freeze container. The rht hydronic fill and purge system meets a relatively high head pressure and flow rate as shown in the figure below for filling and purging air from hydronic systems. Designed to increase heat transfer efficiency protect ferrous and non ferrous metals and lower system.

Using a mixture of 70 water and 30 glycol your system will be frost free up to 12 degrees celsius. Many hydronic heating systems especially those that incorporate radiant floor heating will utilize glycol to provide a level of safety against burst pipes and the resulting damages that can occur to the building and the system. Note that liquids are not sensitive to what we call the temperature felt. This article series describes how to add anti freeze to a heating boiler and to the hot water or hydronic heating system piping baseboards convectors radiators etc.

Effective in heat exchangers hydronic heating solar systems and chilled water systems containing aluminum. Affordable fluid management for radiant heating systems. Blends 98 propylene glycol based fluid with special inhibitors. Both ethylene and propylene glycol possess many characteristics that make them ideal for use in heat transfer systems where protection from freezing is required.

To protect the system from freeze damage. Using a mixture of 50 water and 50 glycol your system will be frost free up to 34 degrees celsius. Too much glycol will therefore increase energy costs as the system works harder to accomplish the desired heating or cooling. Underfloor heating is the most common method of preventing floors from heaving in refrigerated warehouses there are a few methods of underfloor heating electric heat pumped fluid glycol forced ventilation natural ventilation.

Desirable properties include high boiling points low freezing points stability over a wide range of temperatures and high specific heats and thermal conductivities.
