Adjusting A Mixing Valve On Radiant Floor Heating

Adding a basement radiant floor heating system to a water heater is a very popular option for many homes.

Adjusting a mixing valve on radiant floor heating.

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. The schematic below illustrates this approach. Therefore addition of a mixing contol to a radiant floor system will signigicantly protect your investment. The baseboard or cast iron radiator zones for example receive super hot water straight from the heat source.

This will protect against component temperature failure should dirt sediment or other mechanical failure cause a mixing valve to become inoperable.

Taco power mixing valves are also for solar hot water tanks when needed to reduce water temperature to safe levels for home use.

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. Thermostatic mixing valves are for controlling water temperatures in pex radiant floor heat solar hot water heating and other hydronic applications. Radiant floor heating systems are very susceptible to heaitng problems due to water temperature. Mixing valves come in three packages.
