As more Baby Boomers reach retirement age, there is a higher demand for innovative technologies that empower senior citizens to live independently. One such technology is the wi-fi thermostat. Maintaining a comfortable indoor environment is essential for a healthy lifestyle, and wi-fi thermostats can make it easy for a senior to keep their home at an optimal temperature. Consider the following features of the latest wi-fi thermostats and how they can support the lifestyles of seniors who live independently:
- Accessible from a mobile device. Perhaps the most important feature of today’s wi-fi thermostats is that they are accessible from a mobile device. Instead of having to walk over to the thermostat in order to change the temperature of the house, a senior can simply tap the screen of their phone or tablet. That’s ideal for seniors who have challenges with mobility, as well as those who are often out-and-about and want to make sure they arrive home to a comfortable environment.
- Large, easy-to-read touch screens. Many of the latest wi-fi thermostats today have large, well-lit screens that are easy to read, even from a distance. That makes it easier for seniors to check the temperature and determine whether or not to change it. Plus, the majority of thermostat manufacturers have switched over to touch screens, which means that seniors no longer have to deal with tiny buttons.
- Programmable and non-programmable options. With most of the wi-fi thermostats on the market today, users can choose between programmable and non-programmable options. As a result, a wi-fi thermostat can work for seniors with a variety of different lifestyles. For instance, seniors who have a specific schedule for when they will be out of the house can program the thermostat so they won’t forget to turn it off and waste energy (and money) on heating or cooling while they are away. At the same time, those who spend most of their time at home can choose a traditional manual setting that gives them full control of the environment at every moment.
Whether you’re looking for technologies to support a parent or friend, or whether you’re a senior yourself, a wi-fi thermostat can really make a difference when it comes to the ease of heating and cooling your home. National Air Warehouse offers a wide range of wi-fi thermostats at affordable prices, and we offer free shipping, right to your home. Contact us today to learn more about our products!

If home builders can learn anything from the winter of 2017-2018, it’s that an effective heating systems is essential for a comfortable home. As temperatures have dropped to record lows around the country, home builders need to be aware that more clients will be interested in the ability of their home’s furnace to keep their family safe and warm, regardless of the weather outside. As a home builder, one of the decisions you have to make is whether an upflow furnace or a downflow furnace is the best choice for your project. In order to figure that out, it’s important to examine some of the distinctions between upflow and downflow furnaces, as well as what they might mean for the heating of the home.
Upflow vs. Downflow Furnaces: The Basic Differences
At the most basic level, there are key differences in the ways that upflow and downflow furnaces heat and distribute air. With an upflow furnace, the air enters the bottom of the unit, is warmed in the heat exchanger, and then is released from the top of the unit into the ductwork of the home. A downflow furnace works in the exact opposite way: the heat enters the unit from the top, gets warmed in the heat exchanger, and then is released from the bottom of the unit into the ductwork of the home. That means that upflow furnaces are typically situated in a basement or crawl-space, while downflow furnaces must be stored in an attic.
Considerations for Different Projects
If you are trying to decide whether an upflow or downflow furnace makes more sense for your project, here are a few things to keep in mind:
- Energy efficiency. Heat rises, so upflow furnaces are often more energy efficient than downflow furnaces. If you’re looking to cut the carbon footprint of your home building project, an upflow furnace can help you reach your efficiency goals.
- Building and flooring costs. If you’ve already planned a basement for your home building project, this isn’t an issue but if you’re adding a basement or crawl-space to your home building project for the sole purpose of creating a space for an upflow furnace, costs can go up significantly. At the same time, adding reinforced subflooring in the attic for a downflow furnace can also be expensive.
- Installation challenges. The installation process for downflow furnaces tends to be more difficult, and you have to pay closer attention to building codes requiring reinforced subflooring.
- Homeowner preference. Some homeowners simply feel more comfortable in rooms where the heat comes below, rather than being dispersed from above. It’s a good idea to check with clients to find out about their preferences.

When you are remodeling a home or office building, you need to make sure that the gas furnace is sufficient to guarantee a comfortable temperature throughout the newly remodeled space, no matter how cold the winter weather gets. However, things can get tricky if you realize that the size of the cased coil that is required to support the needs of the newly remodeled building is too large for the existing furnace. Read on to learn how a Rheem plenum adapter accessory can help you resolve this problem.
Rheem Plenum Adapters: The Basics
At the most basic level, a Rheem plenum adapter can make it possible for a nominal sized cased coil to be installed on the next-smallest size of gas furnace. More specifically, a plenum adapter can allow you to do the following:
- Fit a 17.5-inch-wide coil 14-inch-wide furnace
- Fit a 21-inch-wide coil with a 17.5-inch-wide furnace
- Fit a 24.5-inch-wide coil with a 21-inch-wide furnace
This might seem simple, but it can make a huge difference for home remodelers, in terms of both time and cost. By using a plenum adapter, you can avoid the hassle and expense of replacing an existing gas furnace that is not sufficient to meet the needs of the remodeled space. Rheem plenum adapters run about 76 dollars, which is nothing compared to the cost of a new furnace. Plus, the installation process for a plenum adapter is relatively simple — just two steps for an upflow furnace and three steps for a downflow furnace.
Fitting a Plenum Adapter to an Upflow or Downflow Application
When you are buying plenum adapter for a gas furnace, you need to make sure that the accessory is designed for the type of furnace you are working with. An upflow system pushes air vertically out of the top of the furnace, usually from a basement. A downflow system pushes air from the bottom of the furnace, down into the vents, usually from an attic. There are slight differences in the designs of plenum adapter accessories for upflow and downflow applications, so you need to make sure you are getting the right one for your system.
National Air Warehouse offers Rheem plenum adapter accessories for upflow and downflow systems. As a home remodeler, you can also find a wide variety of other high-quality products from Rheem, one of our featured brands. Contact us today to learn more about all of our products!

When you are buying a new furnace or air handler, you may be asked to choose a heat strip size. Depending on the product, heat strip sizes can range from 5 kW to as high as 20 kW. Ultimately, the choice you make can mean the difference between enjoying warm, cozy winter nights at home with your family and shivering through endless evenings of uncomfortable cold, wrapped in blankets and layered clothes.
Of course, the size of your home is the most important factor, because it determines the volume of space that needs to be heated. However, there are several additional factors you need to consider when choosing the appropriate heat strip size for the furnace in your home. These factors can vary between homes, and they can make a big difference when it comes to making the appropriate decision for a heat strip size. Consider the following:
- The climate in which you live. If your house is located in the Midwest or Northeast,where the temperature regularly drops below freezing in the winter, it is likely that you will need to choose a heat strip size that is larger than the size required for someone living in the Southeast in the same size house. Watching temperatures hit record lows this year, homeowners in the Midwest and Northeast don’t want to take the risk of choosing heat strips that are too small.
- The insulation in the home. If your home is well-insulated, you may be able to get away with heat strips of a smaller size. However, if your house is poorly insulated, you may need to choose heat strips of a larger size, even if you live in a climate that is generally warm.
- The size and location of the windows. Depending on size and location, windows can either increase or decrease the heat load of the home. Uninsulated windows can transfer cold air into the home, and if they are drafty, things can get even worse. At the same time, strategically positioned windows can also let in sunlight and decrease the heating needs of your house.
When you choose heat strips that are above the standard size for your furnace or air handler, you typically have to pay a slightly higher price, but choosing the right size is typically well-worth it for homeowners. For instance, going from 5 kW heat strips to 10 kW heat strips for an upflow air handler can cost as little as 15 dollars — typically representing an increase of only about 2 percent of the total cost. As a homeowner, it’s usually best to focus on the other relevant factors when choosing athe right heat strip size for your home.
