How Do Heaters Work?

First, let's review how heaters work. You'll want to look at the fuel used to power these devices and how they distribute heat throughout your home. Most heaters use heating oil, propane, electricity, natural gas, or wood pellets.

Central, space, and supplemental heating systems are ways to classify the overall mechanism of heaters. The terminology explains how the device provides warmth for an entire building or a particular space.

In a central heating system, heat gets distributed in equal amounts across all the rooms of a house. In a supplemental heating system, homeowners turn up the temperature in specific rooms of a house to economize energy use.

A space heating system is a portable device that heats a small to the medium-sized area, providing immediate comfort to surroundings. Some space heaters use biomass such as logwood, wood chips, and pellets.

Heat Sources For Heating Systems

We will cover different heat sources. Each has advantages and disadvantages you should know. Their respective uses and designs depend on the availability and abundance of fuel types, building location, climate, and homeowners' preferences.

1. Furnace

A central furnace is the most common inexpensive heating system. It provides heat throughout several rooms of a house by pushing heated air through a network of ducts. A blower motor or fan forces the movement of warm air. 

Using a gas-fired furnace is advantageous for its cooling and heating capabilities. But, it may cause a fire, explosions, or carbon monoxide poisoning. Another disadvantage of a furnace is the loud noise coming from a blower motor. 

2. Boiler

A boiler, which is classified under central heating systems, heats water to produce steam. Then, it uses a pump to circulate hot water through pipes to radiators around the house.

Boilers can be expensive to install but allow zoned heating and cooling. A zoned heating system lets homeowners regulate the temperatures in different rooms individually using separate thermostats. This helps save more on utility bills by heating specific zones in the house.    

3. Heat pump

Heat Pump ground source system

Powered by electricity or natural gas, an air-source heat pump acts as a reverse air conditioner. It collects and absorbs heat from the outside and discharges it inside the house through an indoor air handler. In comparison, a ground-source heat pump uses geothermal energy from underground. 

4. Electric space heater

Affordability and portability are the best features of an electric space heater. This plug-in heater gets filled with oil and converts electric current into heat, similar to an iron or bread toaster. Also, it's ideal for small spaces such as home offices, kitchens, and bathrooms.

Despite being environmentally friendly by not using high-polluting petroleum products such as oil and natural gas, the operating cost is quite high.

5. Active solar heating

As the name suggests, this system uses solar energy to heat liquid or air, and transfers the heat directly into the interior space. Some solar heat can get directed to a storage system for later use. 

Solar heat can get distributed around the house using a radiant floor, baseboards, radiators, or a central forced-air system. However, it can only reach 100% efficiency when supplemented by other home heating systems. 

What Heaters Are Safe For Indoors?

There are many indoor-safe heaters available on the market. Their reliability, cost, efficiency, British thermal units (BTUs), and safety have been reviewed carefully. So, you can make the best choice.

Note that the BTU rating of heating gauges the amount of energy a heater uses to produce heat. So, the higher the BTU rating, the more heat a unit can give off. 

1. Campy Gear Indoor Propane Heater

This heater is for the outdoors, but it is safe to use inside your home. It has a heating capacity of 9000 BTU which provide comfort in a 10x20, 12x12 room or 15x15-foot room. It's also has stove features. 

Check this heater out on Amazon.

2. Remington Indoor Propane Heater

This lightweight indoor propane heater has a wind-resistant frame, and can generate 16000 to 32000 BTU to heat up to 300 sq. feet of space. It also includes a safety shut-off valve and tip-over switch.

4. Mr. Heater Portable Propane Heater

This product is ideal for heating enclosed spaces up to 200 sq. feet and can produce 4,000 or 9,000 BTU per hour. Also, it has a low-oxygen safety shut-off system to show when there's a considerable oxygen depletion level in a space.

Why You Shouldn't Use Outdoor Heaters Indoors

Gas-fueled heaters produce some carbon dioxide, nitrogen dioxide, nitric oxide, and carbon monoxide during combustion. For example, a patio heater is not safe for indoor use.

When you use a heater designed for ventilated areas in an enclosed space, the gas it releases builds up because of poor air circulation. As a result, anyone who inhales these poisonous gases may experience nausea, headache, dizziness, and difficulty breathing.

Using outdoor heaters indoors is potentially fatal, so exercise caution.

What Is The Safest Heater To Leave Unattended?

Here are some of the safest heaters, as reviewed by Ozone Hole, that have tip-over sensors, auto energy-saving mode, timers, and cool-to-touch features. Some of which we already discussed in detail before. 

  1. AirNmore Comfort Deluxe Space Heater
  2. Dr. Infrared Heater Portable Space Heater
  3. Asterion Indoor Electric Space Heater
  4. Comfort Zone Oscillating Space Heater

Paying attention to your heater to prevent it from tipping over is inconvenient and worrisome. It's such a relief to know that engineers have designed indoor-safe heaters that we can leave unattended. 

Conclusion
