FAQs

Is it cheaper to heat with gas or electric?

It depends on the type of electric heating system, local energy prices, and how efficiently your home retains heat.

Natural gas furnaces can have lower operating costs than electric resistance heaters in areas where natural gas is relatively inexpensive.
Electric resistance heaters such as baseboard heaters and portable space heaters convert electricity directly into heat, but they can use substantial amounts of electricity.
Heat pumps are different: they move heat rather than creating it directly and can use much less electricity than electric resistance heating.
The U.S. Department of Energy says today’s heat pumps can reduce electricity use for heating by approximately 65% compared with electric resistance heating.
Compare your local electricity and gas prices before deciding which system costs less to operate.

The cheapest option to operate isn’t necessarily the cheapest system to install, so consider both upfront cost and long-term energy use.

Why is my electric bill so high if I have gas heat?

Having a gas furnace doesn’t mean your home uses very little electricity.

Your furnace may use electricity to operate the blower fan, controls, and ignition system.
Air conditioning can be a major electricity expense even when your home uses gas for heating.
Electric water heaters, dryers, refrigerators, lighting, and other appliances can add substantially to your electricity use.
Poor insulation and air leaks can increase the amount of energy needed to keep your home comfortable.
Your electricity rate may also have changed, increasing the cost even if your usage stayed similar.
Check your bill’s kWh usage and compare it with previous months to determine whether the increase comes from higher usage, a higher rate, or both.

Heating and cooling together are typically one of the largest energy expenses in a home; DOE estimates home heating systems alone account for about 30% of the average utility bill.

What is the absolute cheapest way to heat a home?

There isn’t one heating system that is cheapest for every home because fuel prices, climate, insulation, equipment efficiency, and installation costs all vary.

For operating costs:

A properly sized high-efficiency heat pump can be very economical because it transfers heat instead of generating it directly.
DOE says modern heat pumps can reduce electricity use for heating by approximately 65% compared with electric resistance heating.
Improving insulation and air sealing can reduce the amount of heating your home needs in the first place.
Programmable or smart thermostats can help reduce unnecessary heating.
Maintaining your heating equipment can help it operate efficiently.
Compare local gas and electricity prices before choosing between gas, electric resistance, and heat-pump heating.

In other words, the cheapest approach is often a combination of an efficient heating system and a well-insulated home, rather than simply choosing the cheapest fuel.

What are the downsides of using a gas heater?

Gas heating can provide effective whole-home heating, but it also has some drawbacks.

You must pay for natural gas, in addition to any electricity the heating system uses for fans and controls.
Gas furnaces require proper venting and combustion-air management.
Gas appliances need regular maintenance to operate safely and efficiently.
A malfunctioning gas appliance can create carbon monoxide hazards, which is why working carbon-monoxide detectors and professional maintenance are important.
Gas furnaces generally cannot provide air conditioning without a separate cooling system.
Gas prices can change, so operating costs aren’t fixed from year to year.
Older gas furnaces can be substantially less efficient than newer high-efficiency equipment.

How much does it cost to run a 1500 W electric heater for 24 hours?

A 1,500-watt heater uses 1.5 kWh of electricity per hour when operating at full power.

Over 24 hours:

1.5 kW × 24 hours = 36 kWh
At $0.15/kWh: about $5.40 per day
At $0.20/kWh: about $7.20 per day
At $0.25/kWh: about $9.00 per day
At $0.30/kWh: about $10.80 per day

If the heater ran continuously at $0.20/kWh, that would be approximately $216 for 30 days.

Actual costs can be lower if the thermostat cycles the heater on and off rather than running continuously. The basic calculation is power (kW) × hours used × electricity rate.

What are the downsides of using an electric heating system?

Electric heating can be convenient, but the operating cost depends heavily on the type of system.

Electric resistance heaters can consume significant amounts of electricity when used for long periods.
Portable heaters are generally designed to heat a room or small area rather than an entire home.
Electricity prices can make resistance heating expensive compared with other heating options in some locations.
Using multiple electric heaters at the same time can substantially increase household electricity consumption.
Electric heating systems can also place additional demand on your home’s electrical system.
Heat pumps are an important exception: they can provide electric heating much more efficiently than resistance heaters. DOE estimates today’s heat pumps can use about 65% less electricity for heating than electric resistance systems.

What runs your electric bill up the most?

Heating and cooling are usually among the biggest energy expenses in a home.

Heating and cooling: DOE estimates heating alone averages about 30% of a home’s utility bill.
Water heating: Hot-water use can also be a significant energy expense.
Electric dryers: Frequent or long drying cycles can increase electricity use.
Older refrigerators and appliances: Inefficient equipment can consume more electricity over time.
Electric resistance heating: Space heaters, electric furnaces, and baseboard heaters can use substantial electricity when operated for long periods.
Poor insulation and air leaks: These can make your heating and cooling equipment work harder.
Air conditioning: Extended operation during hot weather can significantly increase summer electricity consumption.

If your bill suddenly increases, compare your kWh usage, not just the dollar amount, with previous bills.

What type of heater is the cheapest to run?

The answer depends on your energy prices and the type of heating system.

Heat pumps can be among the most energy-efficient electric heating options because they move heat instead of generating it directly.
DOE estimates modern heat pumps can reduce electricity consumption for heating by approximately 65% compared with electric resistance heating.
Gas furnaces can have competitive operating costs in areas where natural gas prices are relatively low.
Electric resistance heaters are simple and inexpensive to install, but they can be costly to operate when used as the primary heat source for long periods.
A small portable heater can be economical when you’re heating one occupied room instead of an entire house.

The best option depends on your home’s size, insulation, climate, energy prices, and how much space you need to heat.

How many square feet will a 1500 watt heater warm?

A 1,500-watt heater produces roughly 5,100 BTU of heat per hour, but the actual area it can heat depends heavily on the home.

A well-insulated room in a mild climate may require less heating power.
A poorly insulated room, high ceilings, cold climate, or drafty windows can require considerably more.
A 1,500-watt heater should generally be viewed as a single-room or supplemental heating device, rather than a guaranteed whole-home heating solution.
Check the manufacturer’s recommended room size before purchasing.
As an example, one 1,500-watt utility heater is rated at about 5,200 BTU/h, but its manufacturer-listed heating area is only 15 square feet, showing why manufacturer ratings can vary significantly by product and application.

For a reliable room-size estimate, consider the room’s insulation, ceiling height, outdoor temperature, windows, and desired indoor temperature rather than relying on wattage alone.
