Hydronic Heating

Pressure Regulating Valves

Pressure Regulating Valves

Too-high water pressure causes stinging shower spray, dripping faucets, and easy-wear faucet gaskets. Low water pressure can result in equally frustrating problems. Honeywell pressure controls maintain water pressure and can reduce water bills!

Air Elimination

Air Elimination

The efficiency and quiet comfort of a hydronic heating system can be significantly reduced by the infiltration of air into the system. Honeywell air vents and air elimination devices keep hydronic systems operating at their optimum level.

AQUATROL

AQUATROL

Honeywell AQUATROL AQ2000 series electronic controls combine functionality with ease-of-use, making them appropriate for nearly every application.

Backflow Preventers

Backflow Preventers

Honeywell backflow preventers keep heating and drinking water sources separate for safety and peace of mind. These products prevent heating system water from backflowing into potable water when supply pressure falls below system pressure.

Boiler Fill Valves

Boiler Fill Valves

Honeywell boiler fill valves safely control boiler water feed pressure and are used to fill, purge and flush hydronic heating systems.

Expansion Tanks

Expansion Tanks

Controls thermal water expansion in closed hydronic heating systems. Maintains system pressure below safety relief setting range. Welded construction with butyl rubber diaphragm. Potable water models include polypropylene lining to avoid rusting.

Gauges

Gauges

Honeywell offers a wide variety of gauges for added monitoring of you hydronic heating system. These range from pressure and temperature gauges, to the advanced thermowells and tridicators. Pin-point accuracy and easy to ready outputs.

Hydronic Thermostats

Hydronic Thermostats

Programmable and Non-programmable thermostats for Boiler applications

Rotary Actuators

Rotary Actuators

The "Corona" series of Compact Rotary Valves and Actuators provide integrated mixing of boiler supply, boiler return, loop supply, and loop return water in hydronic heating systems.

Service Check Valves

Service Check Valves

Service Check Valves for air vents and expansion tanks allow easy field service without draining system.

Switching Relays

Switching Relays

Zone relays provide simple installation and interface between the thermostat and the boiler. Convenience and reliability in one package!

Thermostatic Mixing and Diverting Valves
