How do I turn off my heating zone?
Just turn the thermostat all the way down, or OFF if it has a switch. The zone valve won’t open and the heat won’t flow. If the thermostat doesn’t go as low as you would like, or has no ‘off’ switch, you could disconnect one wire at the thermostat.
Why is my heating on when the thermostat is off?
A check valve is used to stop the natural convection from warming up your home when your heating is switched off. If the check valve is broken or blocked, heat will rise through your system causing your radiators to stay hot. Once again, contact a qualified professional to come and check what the problem is.
How are the zones of a heating system controlled?
All new heating systems in dwellings must have at least two heating zones. Each of these zones will be controlled by a thermostat and zone valve. An alternative would be individual electronically controlled TRVs. If the hot water is provided from a storage system then the DHW cylinder will require separate time and temperature control.

Do you need to zone a boiler upstairs or downstairs?
EXISTING INSTALLATIONS For boiler replacements on an existing system, it is not necessary to zone the upstairs and downstairs differently, compliance with the zone requirements can be achieved by a single room thermostat or programmable room thermostat.
How does the zone valve on the thermostat work?
When I call for heat using the old thermostat the zone valve opens the mechanical valve… heat works every single time I test/ use it instead of turning on the zone valve manually. At the same time when I test the Rh and W1 wires upstairs there is 0 voltage. Interestingly, testing Rh with Y gives 5-6V.
Do you need 5 zones on a gas boiler?
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? If you have 5 zones (thermostats), then you need some mechanism to control which zones are receiving a flow of hot water. There are two typical ways to handle multiple zones with hot water heat:
How does a Zone Controller work on a boiler?
Use a pump for each zone. When zone (s) call for heat, the zone controller triggers the boiler to run and powers the relevant pumps. There can be some variation from these, especially if your boiler also heats your domestic hot water, but most systems will use either pumps or valves for zone control.
How does a zone valve work on a thermostat?
The zone valve acts as the relay between the thermostat and the boiler by working in conjunction with a transformer. The transformer converts the 110-volt feed from the panel to a lower voltage that matches the thermostat wiring.
Which is better for controlling multiple heating zones?
Approaches to multiple heating zone control for hydronic (hot water) heating systems: Heating zone circulator pumps versus heating zone valves: which approach is better for controlling multiple heating zones in buildings? This article series describes how to diagnose & fix circulator pump problems on hot water or hydronic heating systems.
