1-1/4" NPT Thermostatic Valve

Our price: $126.13

Product Code: 2500025

The Thermostatic Valve is the first item plumbed inside the building (unless the furnace circulation pump is mounted indoors) and helps to prevent the water temperature from dropping below the optimal operating temperature.  Protects against corrosion and freezing by reducing the heat load on the outdoor furnace when the fuel runs out.  One is required for each set of supply and return lines connected to the furnace.  A single 3/4" Thermostatic Valve (p/n 2500024) comes with each furnace.  A separate fittings kit (p/n 1624) for the 1-1/4" Thermostatic Valve is available for easy installation.  For 3/4" supply and return lines, Thermostatic Valve p/n 2500024 and fittings kit p/n 1548 should be used.
