Which is better upflow or downflow furnace?
Upflow furnaces are more efficient for heating and will have lower operating costs for areas with longer heating seasons. Downflow furnaces are more efficient during the cooling months and will save the homeowner on energy during warm weather.
How can I tell if my furnace is upflow or downflow?
Getting right to it, the fundamental difference between the two is in the direction of air flow in and out of the furnace. A Upflow furnace takes in existing air from the bottom of the furnace and blows out filtered warm/cool air through the top. A downflow furnace works in the opposite way.
Why would you put a furnace in the attic?
Installing a heater in the attic provides safety in flood-prone locations. Even when furnaces are installed on the main floor, floodwaters frequently overflow the first floor, severely damaging the equipment. Most floods can be avoided by simply putting the furnace in the attic space of a single-story home.
What does Multipoise mean?
Multipoise. A multi-direction configuration that allows for both upflow and downflow installations.
What is a downflow furnace?
As you may have guessed, a downflow furnace takes in air at the top of the cabinet, warms it, and then disperses it down into your home's ductwork. As such, the placement of a downflow furnace is commonly in attic space, although it can also be placed in a garage or on the main level of a home.
What is a lowboy furnace?
A lowboy is a shorter height furnace with a design typically used for basement room installations with low-height restrictions.
What are the 3 types of furnace?

What is the most common furnace type?
Gas Gas furnacesGas. Gas furnaces are the most common type of heating system installed in homes across the country. This type of furnace requires a connection to a municipal gas line and operates through central air ducts. As the gas heats the air, it travels through the ductwork into various rooms in your home.
How are furnaces classified?
Based on the method of generating heat, furnaces are broadly classified into two types namely combustion type (using fuels) and electric type. In case of combustion type furnace, depending upon the kind of combustion, it can be broadly classified as oil fired, coal fired or gas fired.
What are the different types of gas furnaces?
There are three types of gas furnaces:Single-Stage Furnace. A standard single stage heating system has a gas valve that opens and closes and gas flows into the unit at only one rate: high. ... Two-Stage Furnace. A two-stage furnace can adjust the valve's flow of gas to low or high. ... Modulating Furnace. ... Electric & Oil Furnaces.
What is a multi stage furnace?
Multi-stage furnaces are premium furnaces. Their efficiency (AFUE) is typically above 94%, and they are able to extract heat from the exhaust gases, by reusing them (they are of condensing type). The really important, and what makes multi-stage furnaces special, is their flexibility.
What type of furnace runs on natural gas?
Two, three and multi-stage furnaces have several levels of burner function and modern variable speed fan motors, allowing high electricity savings. They run on natural gas or propane. Condensing furnaces. Most modern gas and oil furnaces are of condensing type, that is, they can recapture and reuse the water vapor and the combustion gases, ...
What is the difference between a 95% and 90% furnace?
A 90% AFUE furnace will lose 10% of heat during the combustion process, while a 95% AFUE furnace will lose only 5%. See our own videos on Furnaceshere:
Why do top furnaces have sealed combustion?
Top furnaces – contrary to 80%+ and other older furnaces - have sealed combustion (important for safety and health reasons) and, as mentioned before, are able to provide more comfort, less drafts, less noise and a quicker heating, responding to thermostat settings.
How does a stage furnace work?
The technology, how they work. While single furnaces operate like a car in a stop-and-go line, stage furnaces make slight adjustments. They have special valves and a variable speed air blower motor that allows them to operate in very small increments.
Why are top furnaces important?
Top furnaces – contrary to 80%+ and other older furnaces - have sealed combustion (important for safety and health reasons) and, as mentioned before, are able to provide more comfort, less drafts, less noise and a quicker heating, responding to thermostat settings. And that’s very important for zoning(heating the rooms at different temperatures) and for energy savings.
What is the efficiency of a gas furnace?
Most modern gas and oil furnaces are of condensing type, that is, they can recapture and reuse the water vapor and the combustion gases, increasing their efficiency to levels above 90%* (98% in the case of some new premium gas furnaces...)
What is a multiposition furnace?
The Multiposition series of oil-fired furnaces provide the best value in heating comfort for your family. Multiple speed blowers allow airflow to be matched with the needs of your home eliminating “gusts” of hot or cold air and increasing overall comfort. Each furnace has a completely insulated combustion chamber to provide quiet operation and clean burning performance. The oil burner is equipped with a solenoid oil valve that ensures clean starts and quiet shut-downs of the burner. The Multiposition series is capable of achieving up to 85% efficiency due to its unique heat exchanger design, high performance oil burners and increased fibre-reinforced foil faced cabinet insulation. The result is increased energy savings and lower fuel bills.
What is direct sidewall venting?
Direct Sidewall Venting is an effective alternate method of venting combustion products through an outside wall of the house, rather than up a traditional chimney. This method utilizes the burner to efficiently exhaust products of combustion from the heating equipment.
The Technology, How They Work
- While single furnaces operate like a car in a stop-and-go line, stage furnaces make slight adjustments. They have special valves and a variable speed air blower motor that allows them to operate in very small increments. Multi-stage furnaces may begin at the highest blower level possible, but once enough heat is built up they will only push small a...
Two Stage Furnaces
- Two-stage or three-stage units have some similarities with the more advanced modulating/multi-stage furnaces. But they do not work in small increments. As their name suggests, they have intermediate stages: they can operate, say, at 40%, 65% and 100% of their full capacity. Having a On/Low stage, for instance, can be advantageous in relatively mild weather conditions. Some tw…
Do Multi-Stage Furnaces Deserve Their Higher Prices?
