Natural Portable Gas Heaters
Natural portable gas heaters are a great heat sources for warming garages and take up very little space.
The single gas heaters can warm up to 550 square feet or 2 car garage. They offer clean and efficient source of heat. They are compact, lightweight and space saving units. They are ceiling or wall mounted with thermostat or manual control.
They can operate even during power failures. They are easy to install devices. Most of them do require ventilation or a chimney. They come in models of 25,000 BTU/hour to 40,000 BTU/hour. They get fuel from the natural line of gas at home like LP.
They come in two types: forced air and the infrared ray. Forced air models use blue flame to warm the garage. It is similar to blowing air like a conventional furnace. The downside of this is they stir up sawdust. It usually takes longer to reheat these models. It requires 45,000 BTU to heat a two- to 2-1/2 car garage, and 60,000 for a three-car garage.
It can be installed in the corner, near a gas line and an electrical outlet (needed to power the blower). They are less expensive compared to infrared models.
On the other hand, infrared ray models warm the floor and objects first before heating air. The objects heat the air. These are low intensity infrared heaters. It can heat a two- to 2-1/2 car garage with 30,000 BTU, and for a three-car garage, 50,000 BTU is suggested.
Infrared heaters should be installed a minimum of 7 ft. above the floor. It should also hang down a minimum of 4 in. from the ceiling. Infrared models are more expensive than forced air types.
Advantages of Natural Gas Garage Heaters
They are self contained heat producers and need no boiler.
There is abundant fuel supply.
There is no need for electricity supply.
Disadvantages of Natural Gas Heaters
When using propane gas or natural gas, it gives off a byproduct from the fossil fuels.
It is risky if it is a DIY installation wherein a chance of gas leak is there.
These heaters are not portable. They remain where they are installed.
The effect of the natural gas price instability
Hot water heaters
They are also known as steam unit heaters. They transfer heat from the hot water to the air. It is more efficient when it is forced by a fan. The hot water flows thru a radiator coil blown by the fan. Heat is absorbed by the air and warms the temperature.
They come in two models: the vertical and horizontal type. Vertical units placed in the ceiling blows warm air down space. They are usually used in larger spaces. Horizontal units are placed along walls and blow air. They are usually used in smaller spaces like garages.
Benefits of fan forced hot water unit heaters in garages or workshops:
There are no odors and no byproducts of combustion.
Easy to maintain.
Horizontal units have adjustable louvers to help direct warm air
Durable with corrosion resistant paints
Compact and lightweight for simple installation.
The fan is an air circulator during summer.
Drawbacks of fan forced hot water unit heaters in garages:
If there's failure, water can freeze in the garage.
A home boiler system is mandatory.
Hot water piping is required to make water flow from boiler to heater.
More complex controls because of heater and boiler
Fan forced units move large volumes of air which can kick up dust.

The newest ones are the safest, they come equipped with oxygen sensors that detect low oxygen situations and cut the flame off until the oxygen level returns. They are very efficient but have one drawback, they put off a LOT of moisture into the air. Now granted, that can be a good thing but they really produce a lot of moisture and you can quickly get too much in the air resulting in mold and mildew problem. They are best used as a supplement to a good forced air system. Don't let people scare you on these, properly used, they are a plus.

An Excellent question!
Mostly because heaters, furnaces and fireplaces run more hours and are much larger burners than a kitchen stove is. You probably run your stove for what? 2 hours a day tops? It is only little 10,000btu burners for the stovetop and a 15-25,000btu for the oven. That's pretty small. Yes there are products of combustion from that, but not a lot.
A furnace on the other hand will run 8 hours or more out of a day in heating season. It is more on the tune of 70,000 btu's or more. A lot more nasty gases coming from that, that you don't want to be breathing!
Any home with any fuel burning appliance or attached garage, should have a carbon monoxide detector on each floor.

Well, you are right and wrong. A matter of semantics,There is a little tube that is above the pilot. The heat from the pilot heats this tube (thermocouple) and it produces millivolts. The millivolts energize a small magnetic valve within the gas valve ( behind the knob you spoke about earlier) The magnetic valve is the safety device that allows the main gas valve to operate.If the pilot goes out the thermocouple cools and stops producing millivolts and deactivates the magnetic valve. Yes, there is electricity, but not wired to the main house system. It produces it's own power. The house could blow away and the tank will still produce hot water..It could be embarrassing to bath without the house, but it could be done..You girl is right in as much it is not reliant on the power company to operate. Now, be nice to each other. You are both right. Although I'm on her side…
