Multi-zone thermostats. You'd have a bedroom, living room, kitchen and perhaps even an office. All these zones need to be heated (or cooled) – but not necessarily at the same time. When you get up out of bed in the morning and make your first cup of coffee, you prefer the kitchen to be warm instead of your bedroom.
Dual Is Better Than One. A dual-fuel furnace takes on the problem with a hybrid approach that combines a heat pump and a backup gas-fired heater. As long as outdoor temperatures remain above the balance point, the heat pump handles the job of keeping the house warm with typical heat pump energy-efficiency and low operating costs.

Trane 95 and 90 gas furnaces deliver at least 90% efficiency, far exceeding the government minimum standard of 80 AFUE for new furnaces. If you have a furnace that is at least 10 years old, it probably has an AFUE somewhere between 60 and 70 – meaning up to 40 cents of every dollar you pay for fuel is wasted.
Direct line or high voltage systems use a 110v to 240v power source. These are generally baseboards and other electric heating systems and they require special attention when looking for a thermostat (meaning not all thermostats will work with these).
To deal with the excess air produced by your HVAC equipment, you'll probably need a bypass duct that connects your supply air to your return plenum. The zone calling for air will receive sufficient cooling for the associated space, and any excess air will enter the bypass duct.
How much should a new dual zone HVAC systems cost? My home is approximately 1600 sqft. I'm buying an old 1600 sq. ft. house with a 1979 furnace & AC upstairs and a 1997 & AC furnace downstairs. How much should
In this video, This Old House plumbing and heating contractor Richard Trethewey explains how to create zones in a hot-water heating system.

Dual Zone Wall Mounted Mini Split Heat Pumps. Filters: Indoor Unit Size(s) Mini split systems can have one or more indoor units connected to a single outdoor unit. Indoor Unit Size(s) specifies what indoor unit sizes are used in a system. For example (09 + 12) means the system includes a 9k BTU unit and a 12k BTU unit.
You want multiple zones on a single furnace. To achieve this you need more than an additional thermostat - you need electronically controlled baffles in your heating system. The way such systems work is - you have each "zone" blocked off by a baffle, and a thermostat in each zone.

Mar 21, 2009 · A dual zone HVAC is one where there are two controllers that are configured to regulate separately the temperature in two sections of the building. For example, in a home, it might be practical to have a dual zone system where one zone covers the public rooms (living room, kitchen, etc) and the other is the private space (bedrooms, bathrooms, etc).
Aug 06, 2014 · The other way that the term "zoning" is used is to describe a single duct system attached to a single HVAC system that serves multiple zones. In most homes with forced-air HVAC systems, each thermostat is connected to its own heating and cooling system. The home is zoned, but the HVAC system is not.
Aug 26, 2011 · The bypass duct steals air. Even with all three zone dampers open, the bypass duct has a big pressure difference across it, and air is lazy. It'll cheat and take the path of least resistance whenever possible, in this case the bypass duct.
A two-stage furnace works by using a different set of programming than a normal one-stage furnace. Simply put, when it is only moderately cold inside, then the furnace's control board opens the fuel control valve to the partially open position, and heats the house to the desired temperature before turning off.
Zone heating and cooling systems are comprised of an outdoor unit connected by refrigerant piping to one or more indoor units. Indoor units come in a variety of styles, and can be networked together to create multiple zones – each controlled separately. A single outdoor unit can create one large zone, eight unique zones, and anything in between.
In theory, dual fuel heating makes sense Most dual fuel systems are set up so that electricity heats your home when the outdoor temperature is greater than 40 degrees. When it dips below 40 degrees, natural gas heat kicks in. The thinking is that it's overkill to heat your home with gas when things are "cold, but not that cold."
