Should You Buy a Two-Stage Furnace to Save on Utility Bills?
Are you wondering whether or not to invest in a two-stage furnace? Would it be worth the extra expense? The truth is, one type of furnace won’t suit everyone. It all depends on your situation, where you live, your home, and heating needs. However, it always helps to be aware of the differences between a tone stage furnace and a two-stage one. Here are some differences between the two and the advantages of a two-stage furnace.
What is a Two-stage Furnace?
A two-stage furnace is a furnace with two degrees of warming power. The primary stage (low warmth) will work somewhere in the scope of 70 and 80% of the furnace’s assessed limit.
The furnace will go to the next stage (high warmth) under one of two conditions:
- The radiator’s working time, or
- if the indoor controller distinguishes that it must do so, as it is getting a lot colder outside and in the house.
For example, when a radiator is assessed at 80,000 BTU turns, it will work at 60,000 BTU (75% of 80,000 BTU). If the radiator is running for 10 minutes, the furnace will find that it is not warming the house or apartment enough, and will change to high warmth to fulfill the temperature requirement.
To sum up, the key differentiation between a one-stage furnace and a two-stage furnace is that the single-stage range has only one warming power.
Single-stage vs. Two-stage: Key Differences
Every furnace type has a specific gas valve type, which gives it a different heating capacity and burning rate:
- Single-stage furnace: The gas valve of this type of furnace can work at maximum capacity. For example, if the furnace’s power is 100,000 BTU/hr, it will always work at that BTU/hour.
- For two-stage furnaces, it is different. The valve can open at seventy percent of maximum capacity. It can operate at 70,000 BTU/hr or 100,000 BTU/hr, depending on how cold it is in your home and outside.
What separates the two-stage furnace from standard models is its double stage burner. Conventional furnaces have single-stage burners that consistently work at max speed. In contrast, two-stage furnaces burners can switch to and from high-and low-stage heat creation, depending on the warmth they’re required to generate.
When indoor temperatures are a few degrees lower than wanted, two-stage furnaces will start working at high force, warming your living spaces as fast as possible. After that, they change to low-heating mode, creating merely enough warmth to keep the same warmth throughout the day.
To include significantly greater adaptability and productivity, many two-stage furnaces have variable-speed fans, increasing or lowering the furnace’s pace of warmth circulation all through the home. Finally, The more stages a furnace has, the greater the air filtration and temperature balance it will offer you.
Advantages of a Two-stage Furnace
The two-stage furnace has more efficiency than the one-stage furnace. If the home is not too cold, it will release less fuel and save energy that way. Suppose the temperature is five to ten degrees outdoors. In that case, a one-stage furnace will be working in the open position, where a two-stage furnace will run in a partially-open position, using seventy percent of its power only.
While it is true, a two-stage furnace costs more when it comes to purchasing and installation, and it will save you money long term. It also reduces temperature fluctuation at the house and will heat the home and let it cool when it is less cold outside and work in a more “intelligent” way than a one-stage furnace. It gets the apartment or house to the desired temperature and then keeps it constant through smaller burns. This uses less fuel and saves money.
A recent report finished by ASHRAE (American Society of Heating Refrigerating and Air-Conditioning Engineers) said this: “… while the 2006 ASHRAE test method shows just a 0.4% diminishing in fuel use. The power use of two-stage furnaces instead of single-stage furnaces increases by 11%… “. This increase in power use was generally from the blower engine because of the longer running time.
Disadvantages of the Two-stage Furnace
A single-stage furnace has two significant advantages over a two-stage furnace. They are less inclined to breakdown and cost less. They cost less money to acquire and fix.
Besides, it is easier to find the parts needed for a one-stage furnace than it is for a two-stage furnace. If it breaks down and you need an urgent furnace repair in wintertime, for example, having a one-stage furnace can provide you with a quicker repair. Nonetheless, contractors, these days do have the parts needed for a two-stage furnace as it is more common to have one today.
If your furnace breaks down, and you don’t want to wait to save money for a two-stage furnace, then a one-stage furnace is the best choice for you.
