Hydronic Heating

AQUATROL

AQUATROL

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

Hydronic Thermostats

Hydronic Thermostats

Programmable and Non-programmable communicating thermostats for the AQUATROL Boiler Controls

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.

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.

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.

Service Check Valves

Service Check Valves

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

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.

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.

Thermostatic Radiator Valve and Operators

Thermostatic Radiator Valve and Operators

Thermostatic Radiator Valves and Operators automatically control individual room temperatures, in low pressure steam and hot water heating systems, to provide substantial energy savings. Available in electric or non-electric configurations.

Zone Valves and Motors

Zone Valves and Motors

Honeywell Zone Valves, provide superior quality and reliability, that installers have come to expect. The unique ball seal, ensures a new sealing surface every time the valve operates! Available in a range of models to meet all system requirements.

Switching Relays

Switching Relays

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

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!
