How does a zone zone valve work on a hot water heater?

Zone Valves on Indirect-Fired Domestic Hot Water Heaters. A separate loop of piping conducts water from a nearby heating boiler, through the coil in the bottom of the indirect fired water heater tank (thus transferring heat to water in the water heater tank), and back to the heating boiler.

What happens when the zone valve is open?

In all cases, when the zone valve is fully open, an end switch inside the valve tells the heating systems circulator to begin operating, causing hot water to flow through the zone.

How many zone valves do I need for my heating system?

Typically heating systems using zone valves will have two or more zone valves (usually but not always located close to the heating boiler) and a single circulator pump (usually located on the return end of the hot water piping close to the heating boiler).

What to do if your zone valve is not working?

Zone Valve Defects Checklist. Zone valve does not work - jammed, stuck, does not open in response to call for heat at that zone. Provided the wiring and thermostat are correct and operating, if no hot water flows past the valve on a call for heat (feel the pipes for heat) it may be jammed and need replacement.

What is the purpose of zone valves on a boiler?

Explanation of Zone Valves on Heating Boilers - Controlling Hot Water Heat. The control of heating water through these different heating zones may be accomplished by use of zone valves (one per heating zone or area or loop of heating piping) which in turn are connected to individual thermostats.

How many zone valves does a central heating system have?

Typically heating systems using zone valves will have two or more zone valves (usually but not always located close to the heating boiler) and a single circulator pump (usually located on the return end of the hot water piping close to the heating boiler).

How does a zone valve work on a thermostat?

Whenthe thermostat calls for heat in a particular building area, the thermostat switch causes the zone valve to open, to permit hot water to flow through that zone. Other brands of zone valves such as those made by Flair (TM) (problem prone - shown below), and White Rodgers work similarly but their wiring may be slightly different.

How to zone a hot water boiler?

Zoning a hot water boiler system can be done by using these zone valves and separate thermostats for each zone. The boiler piping loop is separated using zone valves on a manifold type system with each zone originating at the manifold. The manifold is piped directly to the boiler. A zone valve is hooked directly to a thermostat.

If you have a natural gas hot water baseboard heating system that has 5 thermostats that control the heat do you need 5 separate zone valves on boiler? Show activity on this post. If you have 5 zones (thermostats), then you need some mechanism to control which zones are receiving a flow of hot water.

How does a zone zone valve work on a hot water heater?

How do you fix a zone valve that wont close?

Reposition the metal plate until they snap and the valve closes. If the valve opens and closes easily this may correct your problem. If checking the power head and the manual lever doesnt correct the problems with the zone valve you may need to replace the entire valve assembly.

What causes a zone valve to go bad?

Sometimes the zone valve will fail to operate properly. This can be caused by a malfunctioning part on the valve itself or by a faulty thermostat or a faulty connection between the two. You may need to troubleshoot the problem from a few different angles before you can determine the exact cause of the problem.

Why is my zone valve not working on my Kenmore range?

The low-voltage wires leading from the controller to the zone valves solenoid may be damaged or disconnected. Check the wires and make sure they are intact and properly connected to both the controller and the zone valve solenoid. The solenoid on the valve may be faulty. In this case, you will need to replace the solenoid.

How does a zone valve work?

In order to achieve this, a thermostat is placed in each room (or zone) that you want to heat. The zone valve opens and closes according to the temperature in the room as determined by the thermostat and your settings.
