Technically no, but it’s a good idea. Valves are to isolate individual zones after the first one. In modern designs you would want to have one valve and pump per loop. The pump usually going before the loop, and the valve being at the beginning or the end.

Can you have 2 thermostats on one boiler?

Yes, in principle, you can use two thermostats to control one HVAC zone. If correctly installed, set, and used you can actually save on your electricity bill. You can also connect more than one thermostat to a single HVAC unit.

Why do I have 2 zone valves?

If you have 2 port valves, (you will have two or three of these valves, one for each heating zone and one for the domestic hot water) identify which one is connected to your hot water cylinder.

How do you separate heating zones?

Quote from the video:
Quote from Youtube video: Yeah now the key to it is this pneumatic damper. Okay boy this looks just like a deflanted peach ball. Absolutely. That's going to go inside now the damper goes inside the ductwork.

How many zones can a boiler have?

There are 3 zones for high temperature that can feed radiators or baseboard convectors at whatever the boiler water temperatures is set to.

Do combi boilers need zone valves?

Components and Overview. Two zone valves are required, one for each heating zones. Each valve is controlled by a thermostat.

How does a 2 zone heating system work?

To combat this, at least two zones are installed – one upstairs and one downstairs. As one zone reaches the desired temperature, the thermostat slows the flow of air to that zone, which forces more air to the other zone and creates more even temperatures throughout your home.

What is a dual zone thermostat?

A thermostat with multiple sensors across the room accurately reads the temperature. It is connected to a damper attached to the room vents. The damper for each room can open or close individually.

How do you use two thermostats?

The general rule of thumb for a two-story home is that you should set each thermostat two degrees Fahrenheit apart from the other. During the summer, when your AC is running, set the upper floor at the temperature you actually want in your home. Then set each floor underneath that to two degrees warmer.

Why does my house have 2 thermostats?

Having two thermostats wired to the same HVAC unit allows you to evenly condition your home. With the use of zones, control, and dampers, you can regulate your home from top to bottom. However, installing two can be complicated. Multiple thermostats allow for more accuracy and efficiency.

Can one thermostat control multiple zones?

With a smart thermostat for multiple zones, you can set up multiple different zones around your house. Following that, you can use your smartphone app or remote control to set different temperatures for all different rooms. That means everyone can have their way and no one needs to compromise.

Do I need 2 thermostats for 2 zones?

Sometimes, central HVAC systems are broken up into multiple zones (through duplication of heat sources, or usage of dampers and ducts). Each of those circuits will require their own dedicated thermostat. If this is the case, we’d recommend a separate smart thermostat for each zone.

How do I balance upstairs and downstairs thermostat?

Here’s what you do: set your upstairs thermostat to your desired temperature goals, and then set your downstairs unit to be two degrees warmer. For most homes, this naturally encourages a temperature balance that’s comfortable and right at your desired temperature goals.

Should upstairs thermostat be higher or lower than downstairs?

The downstairs thermostat should be set to your ideal temperature, and the upstairs thermostat should be about 2 degrees cooler. The heat should be balanced pretty well with this method, and your downstairs will get a little bit extra warmth to keep you comfortable.

Why is it so hot upstairs but cold downstairs?

Cold air is denser than warm air so it stays on the bottom while warm air rises. That’s why the downstairs can feel so chilly while the upstairs is toasty in the winter.
