Glycol Floor Heating Systems

Effective in heat exchangers hydronic heating solar systems and chilled water systems containing aluminum.

Glycol floor heating systems.

Does the glycol protect the metal in my systems. 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. 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. Glycol also called antifreeze is an important compound that hvac manufacturers use to protect hydronic heating systems in cold climates.

When added to water glycol lowers the freezing temperature of the resulting mixture ensuring that it remains liquid even during harsh winter weather. 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. Properties of propylene glycol used as an rv or heating boiler antifreeze and in other applications. Affordable fluid management for radiant heating systems.

Note that liquids are not sensitive to what we call the temperature felt. 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. Glycol pump system fill purge diaphragm pump. Desirable properties include high boiling points low freezing points stability over a wide range of temperatures and high specific heats and thermal conductivities.

Blends 98 propylene glycol based fluid with special inhibitors. We also provide a master index to this topic or you can try the page top or bottom. To protect the system from freeze damage. Designed to increase heat transfer efficiency protect ferrous and non ferrous metals and lower system.

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. Using a mixture of 50 water and 50 glycol your system will be frost free up to 34 degrees celsius. Both ethylene and propylene glycol possess many characteristics that make them ideal for use in heat transfer systems where protection from freezing is required. 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.

Too much glycol will therefore increase energy costs as the system works harder to accomplish the desired heating or cooling.
