You probably know a couple – you may even be part of that couple – with widely divergent temperature preferences. One person is perpetually warm, while the other is usually freezing. For such couples, living together poses challenges in terms of indoor comfort: one person is generally wearing a sweater, or the other is dressed for beach weather in mid-winter.
Or, perhaps, there are areas in your home that are always warm, perhaps due to large, south-facing windows; other areas, such as rooms built above the garage, may always be cool. You’d love to even out the temperature, but don’t know how.
Luckily, there’s now a way to minimize your frustration with indoor temperatures: It’s called a zoned HVAC system, and it’s what you might call a 4C solution: It provides Comfort, Convenience, Conservation and make Common sense.
Zoned HVAC Systems Explained
A zoned HVAC system takes a home’s standard heating system and divides it into zones, each with individual temperature controls that allow variation in temperature throughout the house. As a result, each area of your home can achieve a different level of comfort, and specific hot and cold spots are eliminated.
Most existing HVAC systems can be turned into zoned heating systems with the addition of some key components. The added pieces you’ll need are a zone control panel, thermostats, zone dampers, and, possibly, a bypass damper.
The zone control panel is the system’s nerve center, receiving information about the temperature changes needed in various zones of the home and sending instructions to the thermostats and dampers. It allows your HVAC unit to respond to more than one thermostat in controlling household temperature. When the control panel gets a request for a temperature change, it closes the dampers for zones that aren’t involved before activating the furnace or air-conditioner to deliver air to that zone.
Thermostats provide readings of the temperature in the individual zones and request adjustment from the control panel when the readings dip below or climb above the set point for that.
The zone dampers are “gates” installed in the ductwork to control the flow of air to the various zones in the house. They close and open automatically, depending on their instructions. A bypass damper isn’t essential, but it can be installed to relieve the air pressure through the ducts as dampers open and close.
Planning Your Zones
There are also modern versions designed within a smart home system model. Watch the video below for an overview of a room by room control system:
If you’re considering installing a zoned HVAC system, you’ll need to determine how many zones you’d like to have in your home and which areas will fall into each zone. Think about the temperature preferences of family members and decide whether they will need separate zones for comfort.
Next, consider the layout of your home. Do some floors remain warmer than others? Are there rooms that have specific temperature needs, such as a home gym? Do you have an atrium with high ceilings or a room with numerous windows or an addition to the house that is more energy-efficient than the original structure? You will need to take all of these differences into account.
You’ll also need to think about whether you’d like individual zone control points (thermostats) in certain rooms, making it easier to adjust the temperature from spots where you spend a lot of time, potentially with the aid of a remote control device. Or ask about a programmable thermostat that provides you with the opportunity to adjust the temperature for any zone remotely from your smartphone or tablet.
It’s wise to engage a skilled HVAC contractor to help you plan and execute the installation of a zoned HVAC system. They have the expertise to know what is practical and doable and can assess the layout and design of your home to determine if your zones make sense. They also will know whether your home’s ductwork requires any additional adjustment to make your plans come to life.
Conservation Saves You Money
When you install a zoned HVAC system, you not only benefit from even temperatures and happy inhabitants; you’re also conserving energy and saving money. By using less energy to heat and cool your home, you’re benefiting the environment and saving about 30 per cent on your energy bill. Essentially, you’ll recoup the money you paid for installation over time.
Imagine being more comfortable than ever in your own home, despite the season and the temperature preferences of other family members, while saving money and doing your bit for the environment at the same time. What’s not to like?
