preserve a comfortable indoor temperature is a precedency for homeowners all year around , but in winter you ’re bound to be even more aware of how well your heat system is process — and what to supplant it with should it give out . A traditional gas pedal or electric furnace live about 15 years , butbefore you buy a Modern one , consider if a heat ticker would be a proficient choice . Heat pumps , which also have an average 15 - year life , have been around for more a century but did n’t become democratic furnace alternatives until the 1970s . take to the woods through these eight comparisons — furnace vs. heat pump — to find out which one is best suited to your heating needs .
Heat pumps don’t generate heat—they transfer it.
Agas furnacegenerates oestrus by burn combustible fuel , such as flatulency or propane , while an electric furnace mother heat in much the same manner that a hairdryer would , by blowing atmosphere over a hot element .
Aheat pumpworks on a different thermodynamic principle : It eviscerate heat from the outdoors ( even if it ’s cold out of doors ) and transfers that heat to your home ’s interior . So while a heat pump will not yield heating plant , it is able-bodied to absorb heat via pressurize refrigerant agate line and then release that heat into your home .
Furnaces are better in cold climates.
Since heat pumps draw passion from the outdoors , the warmer the outside melody , the more heat they ’ll allow for . That does n’t mean the out-of-door temp needs to be balmy — a heat pump can trace affectionateness from aviation that ’s below freeze — but as the temperature drop , heat ticker become progressively less effective . If you live on in Climate Zones 1 through 3 ( check out theU.S. Department of Energy ’s Climate Zone Map ) , a warmth ticker might be a good option , but if you ’re in zone 4 through 7 , a furnace will probably be your salutary bet . An exception to this convention is thegeothermal heating system pump , which buries refrigerating lines below the frost level , where the ground temperature remains a static 40 to 50 degrees all wintertime , even though above - soil temperatures may be much cold . If you live in zone 4 through 7 and you want to set up a heat heart , you ’ll need a geothermal model .
Heat pumps are noisier.
While both furnaces and heat pumps can grind , clash , and screech when havingmechanical job , a heating pump is typically the noisier of the two when both are operate as they should . heat energy pumps are notorious for penetrate and knocking as the compressor that circulates the refrigerant through the lines power up or shut down , get sounds from the aviation manager ( the part of the oestrus heart that installs inside the home and pass off warm air ) . This often worries owner of a new heat pump until they realise the noise is n’t a symptom that something is awry . furnace , however , are often located away from the living area — in a basement or utility way — and a soft whoosh of gentle wind is often the only sound they make .
Heat pumps require less space.
Furnaces , which are typically installed indoors , can take up a lot of square footage because manufacturers and local building code often require a 30 - inch headway on all sides for fire safety role . The compressor part of a heating pump , which is located out of doors but close to the menage — in a similar personal manner to an melodic phrase conditioner — ask a minimal 24 - inch headroom around its outdoor unit . Since a warmth heart ’s indoor air handler does not use combustible fuel or yield its own heating system , it does n’t need extra guard clearance . Depending on the type of atmosphere handler that come up with your heating system pump , you might be able to mount it luxuriously on the wall so the unit does n’t encroach on any storey space .
Heat pumps can heat and cool your home.
While a furnace is design to generate only heat , a high temperature ticker warms your home in wintertime and cools it during the summertime months . During hot weather , a heat ticker operates in an very manner to an airwave conditioner , by reversing the press and the flow of refrigerant through its coil . This can be a boastful benefit for homeowners who would otherwise necessitate to buy a separate melodic line conditioner .
Furnaces cost more to operate than heat pumps.
Generating heat need a mess of fuel , but because a heat ticker does n’t give heat , it only needs enough electricity to go around the refrigerant through its pressurized telephone circuit . A heat ticker utilise much less vigor than an electric or accelerator furnace . While precise operating cost depend on the clime where you live , the unit ’s efficiency , and local utility price , for a single winter season , heating costs run an norm of $ 1,550 for a propane furnace , $ 850 for a natural gas furnace , $ 900 for an electric furnace , and just $ 500 for a hotness ticker . Since heat pump work on the same principle as melodic line conditioner during the summer months , the costs to cool down your home with either will run about the same—$300 or more , depending on your mood .
Installing a heat pump is often cheaper.
The toll to have a gas furnace installed average $ 4,500 , and the cost to instal an galvanic furnace runs about $ 4,000 , but you could devote up to 10,000 or more for a high - efficiency poser of either eccentric of furnace . To deploy the most common type of heat heart — an air - to - air poser — you’ll pay an average of $ 3,500 to $ 4,500 , look on size of it and efficiency . instal a geothermic heating plant pump , however , can persist as high as $ 25,000 , due to the added cost of excavating to immerse its refrigerant line . When you view that a heat pump is also used to cool a home , you may save even more money by not having to buy an strain conditioner .
Both should be professionally sized and installed.
When it comes to selecting either a furnace or a passion heart , check that to have a professional heating - and - air technician measure the volume of air in your living space , factor in your climate geographical zone , and view your budget to aid you pick out the correct size furnace or heat pump for your home . A unit that ’s too small wo n’t keep you warm on the dusty day and will force the unit to go extra time , which can thin its lifespan and increase the motivation for repairs . A unit that ’s too large will cycle on and off oft , which can result in indoor temperature variations . Likewise , induction is n’t a DIY project . Both heat pumps and furnace involve verbatim wiring into a domicile ’s master electrical panel , and most local construction code require a professional HVAC technician to connect a gas line to a furnace .
