A gas furnace is much cheaper to install than a heat pump if your home is already fitted with a natural gas supply. Due to their lower energy efficiency, gas furnaces incur relatively higher operating costs compared to heat pumps. Has a long lifespan of about 20 years.
Full Answer
Is a heat pump more efficient than a furnace?
If you live in a moderate environment, a heat pump might be a better choice. In that case, a heat pump can transport heat into your home rather than creating fresh heat, making it more energy-efficient than a furnace. The various types include geothermal, mini-split, ductless, air, and water source systems!
Why are heat pumps more efficient than resistive heaters?
The short answer is that it (usually) takes less energy to move energy than to generate resistance heating. Heat pump efficiency for heating goes down when the air is colder, so there is likely a cross-over point where coil heaters are more energy efficient, which may explain why furnaces dominate for heating in some areas. 3 level 1 LeShatelier
Are dual fuel heat pumps worth it?
Yes, dual fuel heat pumps are worth the investment. They provide the energy-efficient benefits of an electric heat pump with the reliable heat of a gas furnace. Dual fuel heat pumps alternate between electric and gas based on the outside temperature for maximum efficiency.
How much does an electric heat pump cost?
On average, you can expect to pay around $6,000 for a single head heat pump, $10,000 for a multi-head unit and $14,000 for a variable speed central system. Cold climate heat pumps typically cost between $15,000-$18,000. Heat pump rebates are available from BC Hydro, CleanBC and the federal government.
Which is cheaper to run heat pump or gas furnace?
Furnaces cost more to operate than heat pumps. Generating heat requires a lot of fuel, but because a heat pump doesn't generate heat, it only needs enough electricity to circulate the refrigerant through its pressurized lines. A heat pump uses much less energy than an electric or gas furnace.
Should I switch from gas furnace to heat pump?
A Safe and Greener Alternative to Gas and Oil Furnaces Heat pumps are a more energy-efficient, safe, and environmentally-friendly alternative to furnaces that use gas and oil. Because they run on electricity, they don't create the harmful byproducts that come with combustion (burning gas or oil).
What is the downside to a heat pump?
7 Disadvantages of Heat Pumps are: High upfront cost. Difficult to install. Questionable Sustainability. Requires significant work.
Can you replace a heat pump with a gas furnace?
Installing a Gas Furnace Eliminating the heat pump entirely and installing a forced-air furnace is an option, though it is expensive and will require a large amount of work. First, a licensed contractor removes the heat pump's compressor, the outside coil, the inside coil and the refrigerant lines.

Additionally, heat pumps are much safer with no risks for a gas leak, which can expose you to carbon monoxide.
Should I switch to a heat pump?
Benefits of Switching to an Electric Heat Pump Heat pumps are 3 to 4 times more efficient than furnaces. For the average house, installing electric heat pumps in place of a gas furnace and gas water heater will reduce heating emissions by more than 45% over the next ten years.
How Efficient Are Heat Pumps?
The most efficient heat pumps are over 20 SEER and 12.0 HSPF, representing a 500% efficiency rate for the amount of electricity they use.
How does a heat pump get its name?
Heat pumps get their name because they pump heat from one location to another. When heating, they collect heat outside and carry it inside to heat your home. Refrigerant is the key. It has the ability to quickly absorb a large amount of heat – even when outside temperatures are as low as 35-40 degrees.
How does a heat pump compressor work?
The refrigerant expands in the outside coil of the heat pump and absorbs heat. The compressor, powered by electricity, pumps the hot refrigerant gas into your home. It enters the indoor coil in the furnace or air handler where it condenses back into a liquid, shedding the heat in the process.
How efficient is a gas furnace?
The least efficient models are 80% efficient which means that 80% of the heat created is used in your home while 20% is lost out the flue. That’s a lot of waste, when you think about it.
How much does a heat pump save on gas?
Heat pumps and gas furnaces both come in models with different efficiency levels. On average, however, a heat pump will save you 20% to 40% on your utility bills when compared with a gas furnace. Heat pumps are becoming more popular with each passing year and the energy cost savings they offer is one of the primary reasons for this.
Can a heat pump lower your energy bill?
And yet you’ve heard that heat pumps can lower your energy bills. Are heat pumps really cheaper than a gas furnace to heat with? The answer is yes! Heat pumps can be a cheaper source of heat than gas furnaces. We say “can be” because both heat pumps and gas furnaces come in models with varying levels of efficiency.
Is a furnace 80% efficient?
In cool climates, an 80% efficient furnace will lead to very high utility bills.
What is a ductless heat pump?
Ductless heat pumps, also known as ductless mini-split units, are ideal for older homes or homes that do not have existing ductwork throughout the home, as the pump doesn’t require them to flow heat throughout.
How much does it cost to install a heat pump?
EnergySage estimates that the cost of a gas electric or oil furnace is about $5,000 to install. However, a ductless heat pump can be anywhere from $3,500 to $5,000. Note that a heat pump that uses the home’s central air is much more expensive than either option, costing up to $20,000.
How does a heat pump work?
Heat pumps work as reverse air conditioners—they pull the warm air from outside to the inside to heat the home, and they can also cool the home during warmer months. They also use electricity and are more energy-efficient than gas-powered heating systems.
How long does an electric furnace last?
They also have less parts, making maintenance easier. An electric furnace can last up to 30 years!
Which is more expensive, electric or gas furnace?
More expensive to install. Unless you are comparing furnaces vs. heat pumps using central air, furnaces will be more expensive to install. Of the furnace options, electric furnaces are the cheapest and oil is the most expensive as natural gas prices are more affordable.
What is the purpose of a furnace?
A furnace uses the HVAC (heating ventilation and air conditioning) in order to heat or cool the home, based on feedback it receives from the thermostat.
What is the most efficient furnace?
Natural gas furnaces are the most popular in the United States. They heat jets of gas through a burner, making hot hair that is circulated with a fan. They are also the least expensive to run and are the most energy-efficient.
Why does my heat pump make a noise?
While both furnaces and heat pumps can grind, clank, and screech when having mechanical problems , a heat pump is typically the noisier of the two when both are operating as they should. Heat pumps are notorious for clicking and knocking as the compressor that circulates the refrigerant through the lines powers up or shuts down, producing sounds from the air handler (the part of the heat pump that installs inside the home and emits warm air). This often worries owners of a new heat pump until they realize the noise isn’t a symptom that something is amiss. Furnaces, however, are often located away from the living area—in a basement or utility room—and a soft whoosh of air is often the only sound they make.
How much does a heat pump cost?
While exact operating costs depend on the climate where you live, the unit’s efficiency, and local utility costs, for a single winter season, heating costs run an average of $1,550 for a propane furnace, $850 for a natural gas furnace, $900 for an electric furnace, and just $500 for a heat pump. Since heat pumps work on the same principle as air conditioners during the summer months, the costs to cool your home with either will run about the same—$300 or more, depending on your climate.
What zone is a heat pump in?
If you live in Climate Zones 1 through 3 (check out the U.S. Department of Energy’s Climate Zone Map ), a heat pump might be a good choice, but if you’re in zones 4 through 7, a furnace will probably be your best bet. An exception to this rule is the geothermal heat pump, which buries refrigerant lines below the frost level, ...
How does a heat pump work?
A heat pump works on a different thermodynamic principle: It draws heat from the outdoors (even if it’s cold outside) and transfers that heat to your home’s interior. So while a heat pump will not generate heat, it is able to absorb heat via pressurized refrigerant lines and then release that heat into your home.
How does a gas furnace generate heat?
A gas furnace generates heat by burning combustible fuel, such as gas or propane, while an electric furnace generates heat in much the same manner that a hairdryer would, by blowing air over a hot element.
How long does a furnace last?
A traditional gas or electric furnace lasts about 15 years, but before you purchase a new one, consider if a heat pump would be a better choice. Heat pumps, which also have an average 15-year lifespan, have been around for more a century but didn’t become popular furnace alternatives until the 1970s. Run through these eight comparisons—furnaces vs.
How much does it cost to install a heat pump?
Installing a heat pump is often cheaper. The cost to have a gas furnace installed averages $4,500, and the cost to install an electric furnace runs about $4,000, but you could pay up to 10,000 or more for a high-efficiency model of either type of furnace. To install the most common type of heat pump—an air-to-air model—you’ll pay an average ...
Will Renters Pay a Premium for Green Heat?
Maybe, but it doesn’t matter. It is already known that renters do pay a premium for “heat included,” and the recommended monetization for heat pumps is detailed in our article “ Can Massachusetts Landlords Charge for Solar? ”. This article describes how you can provide heat at zero operating cost and charge effectively the cost of oil heat included. This is a straightforward “early adopter” opportunity for landlords and rental housing providers.
What is a MassLandlords heat pump calculator?
A MassLandlords air source heat pump vs furnace calculator has been developed to help owners, managers, and builders evaluate operational costs of all-electric buildings. The spreadsheet calculator allows members to model an apartment, a natural gas furnace or boiler, and a variety of commercially available air source heat pumps. Then each heat pump can be compared to the natural gas furnace or boiler for annual operating cost. This tool is a feature available to members only and will work to compare heat pumps vs baseboard or ducted heat.
How much heat does a Trane Mitsubishi heat pump produce?
The Trane Mitsubishi model above will require 7.92 kW to produce only 54,000 BTU/hr at 5 Fahrenheit. In other words, it will produce 8% less heat for 45% more effort. (If you are carrying out new construction, you should evaluate ground source heat pumps as an alternative to air source. Ground source heat pumps operate on the same principle as air source heat pumps, but benefit from a constant, higher ground temperature of around 50 F.)
How long does a heat pump last?
Heat pumps on the other hand may follow a ten-year maintenance cycle, like a water heater. They may be “very low to no maintenance” for approximately ten years, and then depending on the make and model, may require a new condenser, a partial rebuild, and/or new refrigerant fittings and seals.
How many heat pumps equal a boiler?
Key differences: You need 3 of these heat pumps to equal 1 of these boilers. The heat pump moves much more heat than you pay for, because the heat comes from air not fuel.
How much CO2 does a furnace produce?
A typical apartment-sized gas boiler or furnace heating a decently well insulated and sealed apartment will produce approximately 3 tons of CO 2 per year.
How much energy does a solar panel produce?
Solar panels are not modeled. Depending on the size of the roof, a typical three-decker would produce order of magnitude 10,000 kW-hr per year. (It might be only 7,000, it might be 15,000, your roof will vary.) The Trane Mitsubishi heat pump modeled requires 3,000 kW-hr per year to operate. This means two to three units can be heated without grid electricity.
