A 1500-watt ceramic heater can effectively heat a room up to 150 square feet (e.g., a 10 ft ×15 ft space). Because heat output is limited by physics, this rule of thumb applies to all standard 1500-watt plug-in heaters, though ceramic models excel at providing targeted, fast-blowing warmth.
Most indoor heaters tend to dry out the air, lowering indoor humidity levels. Dry air can cause irritation to the respiratory tract, leading to symptoms like dry throat, cough, and nasal congestion. For individuals with chronic respiratory diseases like asthma or COPD, low humidity can exacerbate symptoms.
To heat a 20x20 (400 sq ft) garage, you generally need between 15,000 to 30,000 BTUs. The exact number depends heavily on your local climate, ceiling height, and insulation:
Never use extension cords for a space heater. That being said, IF you do, get a heavy duty 12ga cord in the shortest length to meet your needs. 1500 watts / 120 volts= 12.5 amps. That's a pretty high draw for any cord so get a good one such as this…
Fourteen-gauge cords can handle up to 1,800 watts (or 15 amps), which is the same as a standard wall outlet. Appliances with a power rating of more than 1,500 watts should be on a dedicated circuit and never plugged into an extension cord.
Never use extension cords or temporary power strips for high-wattage appliances, devices that generate continuous heat, or units with heavy-duty motors. These draw more power than standard cords can safely handle, risking severe electrical fires, voltage drops, and permanent damage to your equipment.
An uninsulated garage door is perhaps the biggest culprit for heat loss in your garage, as there is no barrier to slow the heat transfer out of your garage. In order to protect your garage from heat loss, you need a door with insulation.
To heat a 24x24 foot (576 sq. ft.) garage, you will generally need between 30,000 and 45,000 BTUs. The exact amount depends heavily on your local climate, ceiling height, and insulation levels.
The cheapest heaters to run are generally low-wattage personal heaters, such as halogen heaters or, for larger spaces, oil-filled radiators and infrared heaters that feature, or can be used with, adjustable thermostats to regulate energy consumption. Energy-efficient personal heaters like the Comfort Zone CZ35E are cost-effective choices for localized heating.
In most homes, Heating and Cooling (HVAC) systems drive the highest energy costs, accounting for nearly 40% to 50% of your total electricity bill. Following these, the appliances that run up your bill the most include water heaters, refrigerators, and laundry machines.
If your home uses electricity for central heating, the cost is likely still cheaper than running space heaters. According to Scerbo, “Buying a space heater for every room would increase the electricity bill more than if you had just bumped up the thermostat.”
For individuals with COPD, temperatures below freezing (32°F / 0°C) are considered too cold and can trigger severe flare-ups, chest tightness, and shortness of breath. Even temperatures dropping below 40°F (4.4°C) can cause the dry, chilled air to irritate overly sensitive airways.
The safest space heaters on the market are oil-filled radiators and modern ceramic heaters. These types feature built-in safety mechanisms like tip-over shutoff and overheat protection to significantly reduce fire risks.
It takes time for your home to warm up and cool down. If you're not sure how long it takes, try turning the heating on about 30 minutes before you need it. You should turn it off 30 minutes before you'll stop needing it.
Because they do not use standard grid electricity or conventional electric and gas furnaces, the Amish heat their homes using off-grid, self-reliant methods. The most common systems include wood- or coal-burning stoves, propane and kerosene heaters, and natural airflow home designs.
No, 68°F is not generally considered cold for a house in winter. In fact, experts at the U.S. Department of Energy recommend 68°F as the ideal, energy-efficient temperature for the winter months while you are awake.
The biggest sources of heat loss in a house are typically air leaks, which account for up to 38% of heat loss, followed by uninsulated or poorly insulated walls (roughly 35%) and roofs/attics (roughly 25%). Windows and doors also contribute significantly, responsible for approximately 25% of heat loss through drafts and poor glazing.
For a standard 400-square-foot room (20×20 feet), you generally need about 8,000 to 10,000 BTUs for cooling.
Many Amish homes are built with plenty of windows to help circulate the air and bring in the cooler overnight temperatures. They open the windows on the top floors to help the heat escape while the family retreats to the lower grounds within their homes for comfort.
If the BTU is too low, the AC will struggle to cool the room, run constantly and increase utility bills. In contrast, if the BTU is too high, the AC will cool the room too fast without adequately removing humidity.
There is also a range of electrical devices that should not be plugged into a power strip. "Never plug high-power household items like space heaters, air conditioners, microwaves, toasters, fridges, freezers, or power tools into a power strip.
By connecting these two, you potentially increase the electrical load beyond what either is designed to handle safely. This overloading can cause the devices to overheat, significantly raising the risk of fire, especially when high-power appliances are involved.
No, it is highly recommended that you do not plug a refrigerator into a power strip. Refrigerators must be plugged directly into a grounded, dedicated wall outlet.
