Taco® Heat Motor Zone Valves Provide A Time Proven Method For System Zoning And Control.

Exclusive heat motor design operates silently, while the twist off head allows servicing without disturbing system connections. Provides a convenient way to create individual zones or equipment isolation in a hydronic heating system. High Head Zone Valves are used for high rise residential and commercial buildings. Geothermal Valves are designed for high head, open system zone control. Unique end switch permits control of the heat pump by the valve. Allows movement of cold water into the coil before the heat pump starts. By Pass Valves are used to control the flow to a fan coil or terminal heating unit. Standard Valves are used for hydronic heating applications. 3 Year Limited Warranty.

The Taco® Radiant Mixing Block Combines Injection Mixing Control, Injection Circulation, System Circulation And Air Elimination In A Single Radiant Water Heating Device.

Setting up a radiant heating system can be difficult, because there are many separate factors you need to consider. You need a machine to circulate airflow, circulate heat injections, eliminate dead air and control the whole process. The Taco® Radiant Mixing Block, or RMB-1, is a revolutionary device that combines all of those functions in a single 12-lb device for indoor or outdoor use. It does not require professional installation - all you need are four pipe connections. No complex wiring, external control boxes or balancing valves are required With bronze- casing, wet rotor circulators and a replaceable cartridge design, the Taco® Radiant Mixing Block was engineered to save time and worry. The solid stage microprocessor controls all functionality, and it makes use of low voltage connections for maximum safety and efficiency. With a temperature range from 32°F (0°C) to 185°F (85°C) a flow range of 0 to 15.5 gpm and a max pressure of 125 psi, it is perfect for most residential, commercial and light industrial purposes. The Taco® Radiant Mixing Block uses an LCD screen to display information and features boiler protection, adjustable reset ratio, outdoor reset and warm weather shutdown features, with a hard wire option for greater control.

Taco® X-Pump Blocks Are Used For Contractors Installing Furnace-Based Air Systems with Radiant Heat For Other Areas.

X-pump blocks provide complete isolation between heat generation and heat delivery in any system. Used with open or closed systems, barrier or non-barrier tubing and where the system heat source is a boiler or water heater. Includes variable speed mixing control, heat source circulator, system circulator and heat exchanger in a single unit to provide optimal performance and complete system isolation between the heat generation side of the system and the heat delivery side. Plug-in low voltage connections, maintenance-free wet-rotor circulators and replaceable cartridges provide ease of use and maintenance. Automatic warm weather shutdown conserves energy. Blocks feature an easy-to-read LCD display. Available in X-Pump Block and X-Pump Block, Solar. Blocks may be used as an outdoor reset control, a setpoint control or a Delta-T limiting control. UL® listed.
