Rima Chatterjee

To understand which solution is best for keeping your home warm and cozy, we will explore the cost of a generator vs. a furnace in two sub-sections: How Does a Generator Run a Furnace? and Comparing Generator and Furnace Costs. By examining these two sub-sections, you will be better equipped to make economic choices based on your needs and budget.

How Does a Generator Run a Furnace?


A generator can power a furnace by supplying electricity. This electricity runs the blower motor and control circuits. If the grid fails, a backup generator can keep your furnace running.

It’s cheaper to invest in a generator than to buy a whole new heating system. Electric furnaces cost less to install, but they can be more expensive in the long run. With a backup generator, you can avoid high energy costs.

There’s an upfront price when you buy a generator, but it’s worth it. HomeAdvisor says that replacing an HVAC system can cost up to $9,350. On the other hand, getting a home generator can start at $2,000.

So, let’s compare the costs of generators and furnaces – it’s a battle of warmth versus watts!

Comparing Generator and Furnace Costs


Comparing generators and furnaces costs? Consider installation fees, maintenance costs, and fuel consumption rates. We made a table to help you. Check it out:

            Generator          Furnace
Installation Cost: $3,000 to $6,000Installation Cost: $2,500 to $3,800
Maintenance Cost: $200 per yearMaintenance Cost: $100 per year
Fuel Consumption Rate: 0.5 to 2 gallons/hourFuel Consumption Rate: 0.03 to 0.12 gallons/hour

Generators usually cost more for installation. But, maintenance is cheaper in the long run. Generators also consume more fuel – but they provide reliable power during outages.

Michael Faraday invented the first generator in the 1800s. The furnace has been used for heating since ancient times. Both keep evolving – and offer great benefits, depending on your needs and budget.

Need power during outages? Generators for home use will keep you warm.

Types of Generators for Home Use


To help you understand what type of generator will best serve your home, in this section, I’ll be covering ‘Types of Generators for Home Use.’ We will be discussing three of these types in this article, namely portable Generators’, ‘Standby Generators’ and ‘Fuel Types for Generators’. Each one of these types has certain advantages and disadvantages depending on your needs and budget, and we will cover them briefly.

Portable Generators

Portable Generators are a very versatile and useful tool. You can use them in emergencies, camping trips, and tailgating events. Here’s a table showing the different types and their features and specs:

Portable Generators can also have different starting methods, like recoil start, electric start, and even remote start.

They’ve been around since the early 1900s, when construction companies used them to power equipment on job sites. Now, they’re used for a lot more! Standby generators: ‘Cause who needs electricity all the time?”

Standby Generators

Generators that provide backup in case of power outages are called standby generators. Great when the weather is bad and power may fail.

  1. Air-Cooled Standby Generators use liquid propane or natural gas and range from 5 kW to 22 kW, with prices ranging from $1500 to $5000+.
  2. Liquid-Cooled Standby Generators are more powerful, with a range from 22 kW to 150 kW+ and prices ranging from $6000 to $20,000+. They have liquid cooling instead of air-cooling and operate quieter, so they don’t overheat.

Pro Tip: Before buying a generator, consult an electrician or generator technician to get the right size & model. Fuel types are like choosing between exes – each has their flaws, but you’ve gotta power through!

Fuel Types for Generators

Generators come in many types and with a variety of fuel options. Let’s check out the advantages and disadvantages of each fuel type: gasoline, diesel, propane, and natural gas.

Fuel TypeAdvantagesDisadvantages
Gasoline– Readily available- Portable generators use it- Good for small appliances– Combustible- Short shelf life- Emits fumes and noise
Diesel– More efficient than gasoline- Longer life expectancy- Safer to store in large quantitiesExpensive compared to gasoline- Not suitable in cold climates- Produces carbon monoxide if not ventilated
Propane– Clean burning fuel- Long shelf life (up to 10 yrs)- Can be transported in portable tanks or stored in bigger tanks– Initially more expensive than gasoline or diesel- Must use special regulator & hoses for safety- Not widely available as a fuel type

When selecting a fuel type, consider how long the generator will need to run, storage and transport risks, budget, and environmental impact.

Did you know that the first generator was invented in 1831 by Michael Faraday using principles of electromagnetism discovered by Hans Christian Oersted? Nowadays, generators are used in emergencies or just for fun. So, don’t forget the marshmallows for your blackout s’mores!

Installation of Generator for Furnace Use


To install a generator for my gas furnace, I need to consider the size of the generator, its placement on a concrete pad, and the installation of a transfer switch. To ensure that my generator can provide enough power for my furnace, I need to determine the appropriate size. Next, I need to place the generator on a concrete pad and follow installation guidelines to avoid any safety risks. Finally, installing a transfer switch allows me to switch seamlessly between my main power source and the generator during a power outage.

Size of Generator for Furnace Use

When it comes to furnaces, the size of a generator depends on the type and power needs. Look at the startup wattage, running watts, and motor specs. Here’s a table for common furnace sizes and their corresponding generator sizes:

        Furnace size  Generator size
40,000 BTU3,000-4,000 watts
60,000 BTU4500-5500 watts
80,000 BTU6,500-7,500 watts
100,000 BTU8,500-10,000 watts

These are just guidelines. Individual needs may vary. Plus, extra wattage may be needed for features like a variable-speed motor or a humidifier.

The 2012 Superstorm Sandy incident in New Jersey is an example of why it’s important to get the right generator size. Many residents thought their generators were adequate, but they weren’t. So, make sure to consider all factors when selecting your generator size.

Placement of Generator on Concrete Pad

When installing a generator for furnace use, a concrete pad is needed. It should be stable and level to prevent movement and damage. The size should be equal to the base of the generator, and it should be at least 4 inches thick. The soil beneath should be compacted to avoid settling. Also, it should be sloped away from buildings to prevent water pooling around them.

Generators produce heat, so keep them away from flammable materials. My neighbor made the mistake of using bricks instead of concrete. When a storm hit, his generator toppled over and damaged his roof.

To ensure dependable operation and extend its service life, use a sturdy concrete pad for the generator. Invest in proper installation techniques upfront to avoid a costly mistake.

Installation of Transfer Switch

Installing a generator for furnace use? Don’t forget the transfer switch! It allows the generator to give electricity to the furnace during a power outage. Here’s how to set it up:

  1. Pick a spot for the transfer switch near the electrical panel and the generator.
  2. Switch off the main breaker. Then, connect jumpers from the generator breaker to the transfer switch. And, from the switch to the panel.
  3. Put in the remaining branch circuits to the transfer switch – make sure you wire ’em correctly.

When considering the transfer switch, get the one that has enough amps and wattage for your furnace. It’s key to double-check the installation – any errors could be really dangerous. Get help from a pro or learn more about the techniques to stay safe and warm!
