A Daikin split gas furnace can be paired with a Daikin split air conditioner to provide highly efficient comfort all year long. Here are some things you need to consider when deciding which Daikin split gas furnace is right for your home.

What Does AFUE Mean?

The efficiency of a gas furnace is indicated by its AFUE rating. AFUE stands for Annual Fuel Utilization Efficiency. Essentially, it’s a measure of how much of the fuel consumed actually gets turned into heat for your home. The higher the percentage, the more efficient the furnace is.

Daikin’s split gas furnaces range from 80% AFUE all the way up to an incredible 98% AFUE. While the initial cost of a higher efficiency furnace will generally be more expensive, you may want to consider how much money you could save on your energy bills over the life of the furnace, keeping in mind that the average lifespan of a gas furnace is 15-20 years.

80% Furnace Options

Daikin produces several different models of 80% AFUE furnaces. While all these furnaces have the same basic efficiency, they have a range of different features that could make a difference in your home’s comfort.

  • Some of Daikin’s 80% furnaces have single-stage gas valves while others have two-stage gas valves.
  • Single-stage valves are the basic, traditional kind of valve. They’re either all the way open or all the way closed.
  • Two-stage gas valves, on the other hand, can just open partway when the amount of heat needed is less. This makes the furnace more efficient in milder weather and helps to keep your home’s temperature more consistent.
  • Another furnace component that can affect the comfort of your home is the blower motor.
  • Some of Daikin’s 80% furnace models have multi-speed motors, while others have variable-speed motors.
  • Both of these kinds of motors are good because they can adjust to deliver just the right amount of heat to your home.
  • Compared to the traditional single-speed motors, that improves efficiency and keeps temperatures more consistent.
  • Variable speed motors have a slight edge over multi-speed ones though, because variable speed motors can make very tiny and precise adjustments.
  • They can also slowly ramp up and down when starting and stopping, which reduces noise as well as energy use.

As you can see, even if you’ve definitely decided on installing an 80% AFUE furnace, Daikin still offers a range of options that you’ll want to consider. All Daikin 80% AFUE furnaces include an extremely durable stainless-steel tubular heat exchanger protected by a Lifetime Heat Exchanger Limited Warranty that’s good for as long as you own your home.

High Efficiency Furnace Options

The U.S. Department of Energy defines high-efficiency gas furnaces as those having AFUE ratings of 90-98.5%. When it comes to high efficiency gas furnaces, Daikin offers a range of options to suit various budgets and homes.

One key difference that makes these furnaces higher efficiency is that they include a secondary stainless steel heat exchanger in addition to the primary tubular heat exchanger. This allows even more heat to be transferred into your home rather than being lost in the furnace’s exhaust.

Daikin’s high-efficiency furnaces include a relatively basic but quite efficient 92% AFUE model with single-stage gas valves and a multi-speed motor. For even higher efficiency, Daikin offers 96% AFUE models with two-stage valves and variable speed motors.

As for the ultimate in high-efficiency split gas furnaces, the top-of-the-line model has an outstanding 98% AFUE rating. This is achieved using a variable-speed fan and modulating gas valves. In addition it uses the secondary heat exchanger. Modulating valves are the next step up in efficiency from two-stage valves. Like a variable-speed fan, a modulating valve can adjust in tiny increments to deliver exactly the right amount of gas.

The combination of the variable-speed fan with the modulating valves creates a furnace that can precisely and consistently control the temperature in your home. This enhances your comfort while delivering industry-leading efficiency.

Other Great Daikin Features

There are many other great features that can be found inside of Daikin’s split gas furnaces.

  1. Daikin’s furnaces use a durable silicon nitride igniter, which means that they don’t have a pilot light that wastes energy. The cabinet is insulated, which reduces wasted heat and decreases noise from the blower.
  2. A Daikin gas furnace also includes a self-diagnostic control board. This monitors the system at all times so that it can operate more consistently and reliably.
  3. All Daikin furnaces include that stainless steel tubular heat exchanger, built using their special wrinkle-bend technology that makes it more durable and efficient at transferring heat.

Warranties

The included warranties vary depending on the particular model of split gas furnace, but they’re some of the best in the industry. Warranties available with some models include a Lifetime Heat Exchanger Limited Warranty, a 12 Year Parts Limited Warranty, and even a 12 Year Unit Replacement Limited Warranty. Again, different models come with different warranties, so check the warranties available on specific models before you make your decision.
