Adjusting A Mixing Valve On Radiant Floor Heating

Thermostatic mixing valves are for controlling water temperatures in pex radiant floor heat solar hot water heating and other hydronic applications.

Adjusting a mixing valve on radiant floor heating.

Therefore addition of a mixing contol to a radiant floor system will signigicantly protect your investment. The schematic below illustrates this approach. The baseboard or cast iron radiator zones for example receive super hot water straight from the heat source. To ensure accuracy in adjusting the temperature setting make sure that the hot water supply temperature to the mixing valve is at least 5c 10f hotter than the desired temperature of the mixed water.

A mixing valve is pre installed in this type of manifold. 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. Overheating temperature swings underheating wood flooring shrikage carpet fiber break dow etc. The chief function of a control system is to modulate and limit water temperatures to maximize efficiency and to insure against over heated floors.

Mixing valves come in three packages. It is important that a boiler s high temperature limits do not exceed the maximum temperature rating of the system components. The much cooler radiant floor zones receive tempered water from the mix port of the mixing valve. Taco power mixing valves are also for solar hot water tanks when needed to reduce water temperature to safe levels for home use.
