Adjusting A Mixing Valve On Radiant Floor Heating

Mixing valves come in three packages.

Adjusting a mixing valve on radiant floor heating.

The schematic below illustrates this approach. The chief function of a control system is to modulate and limit water temperatures to maximize efficiency and to insure against over heated floors. Therefore addition of a mixing contol to a radiant floor system will signigicantly protect your investment. It is important that a boiler s high temperature limits do not exceed the maximum temperature rating of the system components.

A mixing valve is pre installed in this type of manifold. Adding a basement radiant floor heating system to a water heater is a very popular option for many homes. Taco power mixing valves are also for solar hot water tanks when needed to reduce water temperature to safe levels for home use. The much cooler radiant floor zones receive tempered water from the mix port of the mixing valve.

Radiant floor heating systems are very susceptible to heaitng problems due to water temperature. The baseboard or cast iron radiator zones for example receive super hot water straight from the heat source. Mixing valves and controls for in floor radiant heating a solid control apparatus is the cornerstone of a well designed in floor radiant heating system.
