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.

Which is better zone valves or circulator pumps?

The “zone valve” gang retort that modern heating zone valves are as reliable or more reliable than [some models of] heating circulator pumps and that a zone valve costs a lot less. And adding zone control to an existing heating system may be less costly by adding a zone valve than by adding a circulator pump.

How many zones can you put on a boiler?

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

Is the circulator installed on the supply or return?

return

Standard good practice among heating techs is to install the circulator pump on the return side of the loop where cooler temperatures can extend its life.

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.

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.

Should zone valves return or supply?

Install zone valves on the supply side of zone circuits to block upward gravity flow. Install a swing check valve on the return side of each zone to block the return side. The latter is necessary because buoyancy forces try to establish two-way flow in the return pipe.

Where should zone valves be placed?

The zone valve needs to be positioned after the boiler and circulator of the central heating system. They can be located either on the hot side (before the hot water goes into the zone) or on the cold side (after the water goes throughout the building).

Where are zone valves located?

Location of Zone Valves



A zone valve can be located right after the boiler and circulator (hot side), or at the end of the zone circuit (cold side). If able, it is recommended to locate the valve on the cold side as it will be less damaging to the valve and improve its life-time.

Should circulating pump be on flow or return?

The best place for the pump(s) is still on the flow side. This keeps the bulk of the system under positive pressure from a combination of the pressure imposed by the system water connection, and then when the pump is running, the pressure provided by the pump.

Where should a circulation pump be placed?

If you had a circulation pump you would position it on the right side so it also points left (same direction as the filter). Positioning it anywhere else or in some cases the opposite end, will cause negative flow and effectively stop most of the circulation.

Does circulator pump flow direction?

Quote from the video:
Quote from Youtube video: The water comes in this side. Goes is forced around that scroll and out that side so the direction of rotation as you're facing this one is counterclockwise.

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.

How do multiple thermostats work?

When multiple thermostats control one system, the house is divided into zones using dampers in the ductwork throughout the house. When one zone needs heating or cooling, the damper for the ductwork in that zone opens, guiding the warm or cool air to that zone.

Should my upstairs thermostat be set higher 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.

How do you balance upstairs and downstairs temperature?

Keep the air moving by turning on the fan setting of your home’s thermostat. Turn the fan from “auto” to “on”. The fan will circulate the air continually throughout the home and can help even out temperatures between floors.

How do dual thermostats work in a two story house?

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.

How do you regulate heat in a two story house with one thermostat?

Set the first floor’s thermostat to your desired temperature, and then decrease the temperature setting on your thermostats by two degrees as you go up. Warm air on the first floor will rise and make the upper floors more comfortable.

Why is my upstairs so hot and downstairs cold in the winter?

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. The temperature differential between the upstairs and downstairs in an average two-story home is between 8 to 10 degrees.

Why is it so hot upstairs but cold downstairs?

Heat rises – Blame physics: hot air rises while cold air sinks. That means your upstairs typically gets hotter than your lower levels, even if your air conditioner’s working in overdrive.
