A mixing valve is pre installed in this type of manifold.
Adjusting a mixing valve on radiant floor heating.
This will protect against component temperature failure should dirt sediment or other mechanical failure cause a mixing valve to become inoperable.
Therefore addition of a mixing contol to a radiant floor system will signigicantly protect your investment.
The chief function of a control system is to modulate and limit water temperatures to maximize efficiency and to insure against over heated floors.
Taco power mixing valves are also for solar hot water tanks when needed to reduce water temperature to safe levels for home use.
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.
It is important that a boiler s high temperature limits do not exceed the maximum temperature rating of the system components.
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.
The schematic below illustrates this approach.
Mixing valves come in three packages.
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.
