HVAC appliances energy cost comparison
Here, we break down what’s usually the most costly use of energy in your home: heating systems. Why are heating systems usually the most expensive?
This is because converting one form of energy — such as electrical energy or chemical energy — into heat requires a lot of power (Note: Power is measured in watts, W). More power means more money coming out of your wallet. This is also why, for example, your dryer costs more per year to run than your washing machine.
The wattage of most home heat pumps, in the warmer months of the year, typically ranges from 545 to 4,285 watts, with an average of 2,415. In the colder months, the range is from around 1,000 to 7,500 watts. Another common generator of residential heat are space heaters. These are especially popular in places where access or usage of utility gas is limited and, not surprisingly, the same places where electrification has grown as prime home heating fuel.
Below is an energy cost comparison chart for a heat pump running for five months of the year during the warmer seasons, five months of the year during the colder seasons, a space heater running for five months, a 10-20 gallon water heater running for two hours per day, and a 30-80 gallon water heater running for two hours per day, in Connecticut:
Appliance (W, average) | Length of Time Used | Cost per Month: Electricity | Cost per Month: Propane | Cost per Year: Electricity | Cost per Year: Propane |
Heat pump (2415 W) | 5 months during warm weather | $515.38 | $239.50 | $2,576.90 | $1,197.50 |
Heat pump (4250 W) | 5 months during cold weather | $906.98 | $421.48 | $4,534.92 | $2,107.40 |
Space heater (1500 W) | 5 months during cold weather | $320.11 | $148.76 | $1,600.56 | $743.79 |
Water heater (10-20 gallon – 1600 W) | 2 hours per day | $28.45 | $13.22 | $341.64 | $158.76 |
Water heater (30-80 gallon – 4500 W) | 2 hours per day | $80.03 | $37.19 | $960.86 | $446.52 |
When it comes to HVAC appliances, using propane as a source of heat and energy is more cost-effective than electricity in Connecticut. Even though propane prices rise in winter months, the increase in energy costs is usually still less than the increase in electricity prices. In Connecticut, the use of utility gas has increased a little since 2010, and it’s the same with the use of electricity for home heating. Usage of propane, however, has exploded in Connecticut, with the number of households relying on propane gas increasing by 132%, from 37,329 homes in 2010 to 86,596 homes in 2022.
Kitchen appliances energy cost comparison
Let’s take a look at a couple of common kitchen appliances, including a refrigerator, dishwasher, and your oven-stove. Although you probably know that propane can be used to fuel your oven and stove, you might not know that propane can also be used for refrigerators. Additionally, since the hot water in your dishwasher must come from a water heater, your dishwasher too can be powered by propane, because propane fuels the water heater.
To estimate how much it would cost to power these appliances per month and per year in Connecticut, we assumed your:
- Refrigerator will be running all hours of the day
- Oven/stove will be run for a total of 1 hour over the course of a day
- Dishwasher will be run for 1 and a half hours per day
An important note on refrigerators: Refrigerators generally have a much lower “running” wattage than their stated average wattage. This is due to the fact they cycle on and off throughout the day. As a general rule of thumb, you can divide your refrigerator’s wattage by three to estimate its actual energy usage. So, a 550-watt refrigerator actually will use about 183 running watts.
Below is the energy comparison of the cost of electricity vs propane on a monthly and annual basis in Connecticut:
Appliance (W, average) | Hours of Use per Day | Cost per Month: Electricity | Cost per Month: Propane | Cost per Year: Electricity | Cost per Year: Propane |
Refrigerator (550 W) | 24 | $39.12 | $18.18 | $469.76 | $218.30 |
Oven/stove (3500 W) | 1 | $31.12 | $14.46 | $373.67 | $173.65 |
Dishwasher (1800 W) | 1.5 | $24.01 | $11.16 | $288.26 | $133.96 |
With electricity costing an average of 29.25 cents per kilowatt-hour ($0.1483 per kWH) in Connecticut and propane prices averaging $3.67 per gallon, it is significantly cheaper to run kitchen appliances using propane vs electricity in Connecticut. Fortunately for those shopping around for different energy sources, Connecticut has several propane dealers across the state to choose from, including Quality Propane Inc., State Line Propane LLC, and Total Fuel Service.
Laundry and living room appliances energy cost comparison
Finally, we turn to the two mainstays of the laundry room — washers and dryers — as well as that hearth of the home — the fireplace. Non-wood fireplaces can be fueled by electricity or propane, as well as many other fuel sources. And since the hot water in your washing machine comes from your water heater, propane can be used to power your washer.
In order to estimate how much it would cost to power these appliances per month and per year, we assumed your:
- Clothes dryer will be run for approximately 4 hours total, one day per week
- Fireplace that will be running for approximately 2 hours total per day during five colder months
- Washing machine will be run for approximately 4 hours total, one day per week
Below is the energy cost of electricity versus propane on a monthly and annual basis in Connecticut:
Appliance (W, average) | Hours of Use | Cost per Month: Electricity | Cost per Month: Propane | Cost per Year: Electricity | Cost per Year: Propane |
Dryer (3250 W) | 4 hours, 1 day per week | $16.52 | $7.68 | $198.27 | $92.14 |
Fireplace (1500 W) | 2 hours per day, 5 months during cold weather | $26.68 | $12.40 | $133.38 | $61.98 |
Washing machine (900 W) | 4 hours, 1 day per week | $4.58 | $2.13 | $54.91 | $25.52 |
As the table above makes abundantly clear, it is significantly cheaper to run laundry appliances using propane vs electricity. The average cost of electricity in Connecticut is well above the national average, as is the average propane price in Connecticut. Still, however, propane remains cheaper than electricity.
Advantages of propane vs electricity
In terms of cost, propane is better than electricity in Connecticut. In addition to the energy comparison breakdowns above, here are some other reasons why propane is better than electricity:
Environmental impact
While both electricity and propane have environmental footprints, the source of the electricity matters a lot. In regions where electricity is primarily derived from coal or other non-renewable resources, using propane might result in a lower carbon footprint. Propane burns cleaner than many other fossil fuels. It produces fewer greenhouse gasses and pollutants.
Higher heating efficiency
Propane has a higher energy content per unit compared to electricity, which means it often delivers heat more efficiently. When used in furnaces, propane reaches higher temperatures faster than electric heat pumps. This makes propane heaters more effective in colder climates where rapid heating might be essential.
Reliability and independence
Propane can be stored on-site in tanks. This allows homeowners and businesses to maintain an independent energy reserve. This contrasts with electricity, which might be subject to grid failures or blackouts. Having a propane tank ensures that even in the event of power outages or disruptions, a consistent energy source remains available.
Economic considerations
In many areas, propane can be a more cost-effective energy source than electricity. While initial setup costs for propane might be higher due to the need for tanks and infrastructure, the ongoing costs can be lower in regions where electricity prices are high. This can result in substantial savings over time for homeowners and businesses alike.
Versatility and adaptability
Propane is a versatile energy source that can be used not only for heating. It can also be used for cooking, water heating, and even refrigeration. This multifunctional capability means that homes and businesses can consolidate their energy needs under one reliable source. Plus, as technology evolves, propane appliances are also becoming more efficient and adaptable. This further enhances their appeal over electric alternatives in certain scenarios.
Is it cheaper to heat with propane or electricity in Connecticut?
Heating a home in Connecticut with a propane heating system is cheaper than an electric system. Plus, over time, propane water heaters can cost one-third less to operate as well as heat water twice as quickly as electric water heaters.
Should I switch from electric to propane?
If you’ve been having a tough time with rising heating and energy expenses, it might be worth contemplating a switch from electric to propane. Connecticut generally has higher costs of living than the national average overall. Propane stands out as a remarkably efficient energy alternative. It often delivers the same, if not better, results with a smaller energy input compared to electricity. This inherent efficiency means you could experience comparable or superior performance. At the same time, you’ll have a noticeable reduction in energy consumption.
Converting from electric heat to propane offers not just an energy-efficient solution. It is also a potentially cost-effective one. With propane’s capacity to heat spaces efficiently, homeowners might discover that their homes remain cozy and warm without the hefty price tag often associated with electric heating. Over time, these savings can accumulate. That makes the switch a financially smart decision for those keen on optimizing their home’s energy use and reducing monthly bills.
