How do heating zone valves work?
Explanation of Zone Valves on Heating Boilers – Controlling Hot Water Heat. In all cases, when the zone valve is fully open, an “end switch” inside the valve tells the heating system’s circulator to begin operating, causing hot water to flow through the zone.
What are zone valves used for?
A zone valve is a specific type of valve used to control the flow of water or steam in a hydronic heating or cooling system. In the interest of improving efficiency and occupant comfort, such systems are commonly divided up into multiple zones.
How much heat does a baseboard hot water heater put out?
A: Sure, let’s say you’re installing 3/4″ baseboard. If your average water temperature is 180 degrees F, each linear foot of baseboard will put out 610 Btu/hr. As the water flows, that heat moves into the air, dropping the temperature of the water as it goes.
How does the temperature of the baseboard affect the heat?
Heat output from baseboard depends largely on water temperature. The chart below shows how pronounced this effect is for a typical residential system. As water flows through a series piping circuit containing several baseboards, its temperature is constantly decreasing.
How does a zone valve on a heating system work?
at ZONE VALVE MANUALS & WIRING. In all cases, when the zone valve is fully open, an “end switch” inside the valve tells the heating system’s circulator to begin operating, causing hot water to flow through the zone.
Why are heating zones different in each building?
Because heating zone piping and zone size or zone area heat loss may vary widely within an individual building, if we cannot regulate the hot water flow in individual zones we may find that when more than one of the thermostats are calling for heat at once, some building areas may be too cold while others may be too warm.

How to create zones in a hot water heating system?
6 Solder together new zone valve assemblies and attach to boiler with solder-less fittings. 7 Install wireless thermostat in room of new zone; locate thermostat away from direct sunlight or cold drafts, and about 60 inches above the floor.
