In cold seasons, the home must be heated up, but this has ended up sucking the life out of the electricity.
However, this has become a minor issue due to the diversification of the home heating system.
One is the gas furnace, an economical yet efficient means of driving the chills out the door.
There are also different types of gas furnaces, each affordable and easy to maintain.
These gas furnaces come in three major types: single-stage, two-stage, and modulating furnaces.
Before purchasing, environmental conservation, fuel efficiency, and the price of the gas furnaces should be considered.
But most importantly, an area’s recurring weather conditions should be considered.
A dependable furnace that won’t break down easily is needed in extremely cold conditions.
A decent knowledge of these clean, innovative furnaces should be in place before purchasing.
Below are the different types of gas furnaces.
1. Single-stage Furnaces
It was named because of its single-stage heat output. This type of gas furnace runs at full throttle and is suitable for extreme cold weather.
Although it is not as efficient as other furnaces, it releases maximum heat that can keep the house warm.
The single-stage furnace has just the on and off speed, with no heat modulator for low, medium, or anything in between.
This is the major reason it is ideal for temperatures below freezing point.
2. Two-stage Furnaces
This furnace is more efficient than the former. It is equipped with two phases. The first stage runs between 65% and 70% throttle.
This stage is the temperature when it is switched on. If the weather is cold at that time, this first stage won’t give out much heat.
However, it is suitable for temperatures above freezing point. When it is modulated to the second stage, higher heat is released.
This type of furnace’s beauty is its ability to provide the home with the appropriate degree of heat.
Unlike the single-stage gas furnace, the two-stage gas furnace does not emit 100% heat.
It is quieter and releases less carbon dioxide into the air.
3. Modulating Furnaces
This is more like expanding the two-stage gas furnace to accommodate more degrees of heat output.
The modulating setting can adjust heat based on the weather conditions.
When switched on, the furnace operates at 35% capacity and can be adjusted up to 100% capacity. A thermostat controls fuel consumption.
Besides, since the fan and gas burner hardly run at full throttle at once, the on-and-off cycling present in the standard furnace can be eliminated.
This has made the modulating furnaces one of the best fuel-efficient today.
4. Natural Gas Furnaces
Furnaces running under natural gas accrue several benefits to the home.
These natural gas furnaces are costly but easy to maintain and can hardly break down.
Although, when they do break down, the repair is relatively inexpensive. However, when they do, repairing them is not inexpensive.
You won’t need to replace them or pay too much throughout for needed repairs.
Natural gas furnaces are the most inexpensive fossil fuels. Therefore, furnaces running on natural gas can reasonably reduce utility bills.
More so, natural gas is pure and clean, making it eco-friendly. One can have a good night’s rest without the fear of pollution or carbon poisoning.
Natural gases are inexpensive, reliable, and efficient. A house can be heated with a limited amount of gas.
5. The 80% Gas Furnaces
This type of gas furnace is mostly found in ancient homes with chimney vents. Here, 20% of the heat produced is exhausted through the furnace vent.
This furnace has an annual fuel utilization efficiency (AFUE) of 80%, making it more efficient than many recommended gas furnaces.
This entails that 80% of the fuel paid for is returned since it is converted to heat energy for home use.
6. The 90% – 97% Gas Furnaces
This type of furnace utilizes a subordinate heat exchanger, which works by diverting combusted gases into a condensing phase, saving about 90 %—97 % of energy.
As the gases are condensed into water, heat is emitted. This results in an increased percentage of AFUE while lowering operating costs in the long run.
