Adjusting A Mixing Valve On Radiant Floor Heating

Radiant floor heating systems are very susceptible to heaitng problems due to water temperature.

Adjusting a mixing valve on radiant floor heating.

Overheating temperature swings underheating wood flooring shrikage carpet fiber break dow etc. A mixing valve is pre installed in this type of manifold. 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. Adding a basement radiant floor heating system to a water heater is a very popular option for many homes.

It is important that a boiler s high temperature limits do not exceed the maximum temperature rating of the system components. Taco power mixing valves are also for solar hot water tanks when needed to reduce water temperature to safe levels for home use. 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. This will protect against component temperature failure should dirt sediment or other mechanical failure cause a mixing valve to become inoperable. Thermostatic mixing valves are for controlling water temperatures in pex radiant floor heat solar hot water heating and other hydronic applications. Therefore addition of a mixing contol to a radiant floor system will signigicantly protect your investment.
