Configurations of a Natural Gas Garage Heater

Natural gas garage heaters blow air straight into the room. Their adjustable louvers permit for perpendicular adjustment of the flow. Almost all the manufacturers provide horizontal louvers that help the air to flow side-to-side. These furnaces have several different categories based on the design of the heat exchanger and the venting type:

Types of Venting

Gravity vented garage furnace:

Gravity vented garage furnaces are heaters that vent naturally and do not need a fan. These furnaces make use of the air inside the garage for ignition. The warm derivatives of combustion come out of the furnace with the help of a gas pipe. They are the least expensive.

Power vented furnace:

Very similar to the gravity vented furnace, these devices have an additional flue-vent booster fan. As soon as the heat is produced, the fan starts to make sure that the derivatives of combustion are properly vented out. These furnaces are the most popular among consumers. The booster fan gives more elasticity with flue pipe.

In fact, most of the major manufacturers of heating, devices are eliminating the production of gravity vented furnaces and are substituting them with power vented heaters. These heaters also allow horizontal venting.

Separated combustion furnaces for the garages:

These forms of heaters are becoming popular by the day. While the conventional power and gravity furnaces make use of space air for ignition, separated combustion furnaces are sealed. These heaters have a couple of flue vent pipes. While one pipe is used to draw in the air from the atmosphere, the other throws the by-products outside. This sealed combustion design removes the possibility of the burning of air inside the garage.

Such heaters work well in places where fine dust particles can catch fire due to an open flame. Moreover, separated combustion furnaces are normally more competent, as they do not make use of the air in one’s space for ignition.

Heat exchanger designs:

Traditional natural gas furnaces for the garage:

These furnaces are narrow and tall. However, since most find them inconvenient, manufacturers are turning towards the newer exchanger designs.

Tubular heat exchanges:

These exchanges are flexible and defy cracking. They allow the furnace to be shorter and wider, which is of great assistance in garages that lack overhead clearance.

How are natural gas garage heaters installed?

Following is the method by which one can install these furnaces

• Hang the furnace by making use of the angle iron or threaded rods. Several heaters contain angle iron which helps them mount straight to the ceiling. However, do remember that when you are mounting a heater you need to follow specifications as to how close the furnace can be mounted to a ceiling or object.

• Install the gas piping.

• Install the vent pipe.

• Wire a wall thermostat (with a low voltage) to the terminal strip of the furnace. 

• Wire the elevated voltage power needed to start the furnace.

Natural gas garage heaters are capable of running any time. They do not require a person to worry about the fuel supply. However, it is best to get in touch with an HVAC expert if you need help with the installation or maintenance of the equipment. 

All about Natural Gas Garage Heaters

A natural gas garage heater is a relatively small unit that can be mounted onto a wall or kept freestanding. This form of the device makes use of natural gas for generating heat, instead of exploiting expensive sources such as electricity. The basic mechanism involves the burning of natural gas, circulated by a pump, to produce the heating effect. The vents, built on the furnace, permit the warm air to break out and envelop the garage with an air of heat, normally covering a decent radius. These devices have the capability to increase the temperature by several degrees.

The basic operating principle behind this furnace is as below:

Whenever there is a requirement to generate heat, the gas from the fuel pipe flows all the way through a valve, within the heater. A pilot flame sets fire to the fuel and a flare is produced within the heat exchanger. As soon as the exchanger achieves a set temperature, a fan automatically starts and blows the air through the exchanger. This results in a warmer air being discharged.

Natural Gas Garage Heater Vs the Others

Natural gas garage heater has several other adversaries, differing in the overall mechanism. Two such competitors are electric furnaces and hot water garage furnaces. While electric furnaces are least expensive to install, their overall maintenance is a little high, especially due to electricity being their power source. Similarly, a hot water furnace requires the installation of a home boiler system, and if the boiler is not working properly, the heater fails to produce heat.

Hence, keeping the aforementioned operating drawbacks in mind, natural gas garage heater seems to be the best choice to heat garages.

Fundamentally, there are four things that need to be considered when choosing a furnace:

• Square footage of the garage

• Maintenance cost

• Efficiency ratings

• Warranty 

Benefits of Natural Gas Garage Heaters

1. Efficient:

Efficiency is undoubtedly the best benefit of such furnaces. They have the ability to snuff out immense heat; hence, the money spent by the consumer will go a long way to heat his/her house.

2. Low clearance requisites:

All of the low-profile natural gas garages heaters have extremely low clearance requirements. Saving time and effort.

3. Fast and powerful:

These furnaces are extremely powerful, fast, and self-contained. They don’t depend on a home boiler to provide heat.

4. Durability:

All unit casings are nursed for rust resistance and painted with a high solids coat.

5. Adjustable louvers:

Almost all furnaces come with adjustable louvers that assist in directing the warm air, where it is required the most.

6. Variety:

The natural gas garage heater comes in a plethora of styles and sizes to cater to the varying customer needs and requirements. If chosen suitably, one will not have to be concerned about over or under-sizing. 

Do not forget to consult a capable HVAC professional to ensure that the furnace selected for the garage is the best option for you. Consulting an experienced and genuine dealer is very important.

What to Look for When Considering a Used Furnace?

If your furnace has stopped working, you may be exploring different ways for saving on replacing the system. Buying a new furnace can be extremely expensive but there is another way of saving money: by buying a used furnace.

Here are some things one must look for to get a good deal.

Always buy from a commercial seller who offers refurbished furnace

You may be tempted to buy a used unit from a private seller. However, the possibility of added costs and scams are not worth it. The seller may hide problems, and in case the system requires uninstallation, that will be an added cost.

Purchasing from a commercial seller is a lot safer. You can depend on the claimed quality of the equipment. However, it is still wise to get a technician to inspect the unit professionally before buying it.

Things you should ask a seller selling a used furnace:

Do not get roped into promises of a cheap rate. You must ask the furnace seller the following questions:

1. How old is the furnace?
2. Why did the previous owner want to sell?
3. Which brand is this?
4. What kind of fuel does the furnace use?
5. How good is the performance?
6. Has the furnace received regular maintenance?
7. Is the furnace under warranty?

Some of the things you must check before making the purchase:

You must remember that any heater that was previously owned has experienced at least a little wear and tear. This may lead to several issues. Make sure you check the state of following components before you purchase a used furnace:

1. Pilot light or electronic ignition
2. Burners
3. Heat exchanger
4. Motor and blower fan
5. Pressure switches, limit switch
6. Mechanical gears that may squeak, rumble, or rattle

Things to consider when installing a used furnace:

Installing a refurbished furnace to save money is a great idea. However, if you do not get it installed professionally, you may miss an important aspects required for efficient, safe, operation, such as fuel and venting pipes needed for models with high-efficiency. The ductwork may also waste energy by leaking, leading to increased heating bills.

Investing in a proper installation done by a specialist will add to the upfront cost of purchasing a refurbished furnace. However, improved longevity and performance are all worth it! Moreover, you can be rest assured that your system is properly installed.

If you are worried about investing money in a refurbished or used product, you have other choices for saving money. You can purchase a furnace from a wholesaler at reasonable rates. Models of the previous year can also be bought at a discounted rate.

Irrespective of where you purchase a new furnace for sale, it is extremely important to hire a professional HVAC expert. It takes years of knowledge and experience to diagnose the issues, determine overall condition and assess the age of the furnace.
