Outdoor heaters heat well only to an area between 10 - 40 feet near the heater itself. It depends on location and type of heater you purchase. I recommend buying brand name heaters.
One can purchase outdoor electric heaters by going to Target. Target has both retail stores across the nation as well as a website that outdoor electric heaters can be purchased from.
The size and power ability of the heater will determine the area of heat coverage. Some heaters will only cover an area big enough to keep one person comfortable. Other heaters are taller, and can cover about a 10 foot radius around it. The manufacterer usually installs various safety mechanisms as well.
over outdoor heaters? definitely.
Heaters use electricity to produce heat by resistance.
Choose an outdoor heater that will cover a large enough area for your patio. Electric outdoor heaters are cheaper and require less maintenance. Some electric heaters will include a battery, but the battery life will wear down after time so go with a corded model. Also choose an outdoor heater with a warranty as they tend to break down and can be very expensive to fix. Also choose an outdoor heater with enough weather proofing so it will not get damaged by being outside in the rain or snow during the winter.
Ceramic heaters are generally considered to be energy efficient compared to other types of heaters because they heat up quickly and retain heat well. This can help reduce energy consumption and lower heating costs.
Yes. Outdoors heaters produce heat and radiate it out to the air around them. As they are not in an enclosed environment, they are not as efficient in heating "living" space as an indoor heater, but they certainly can provide much-needed relief from bitter outdoor cold.
At Menards you can buy an outdoor patio heater at http://www.menards.com/main/outdoor/patio-furniture-benches/87-outdoor-patio-heater/p-1651682.htm for $149.99. A patio heater varies in length of life depending on the power source. If you have a propane tank, you can run out if used often in a week. Outdoor heaters are less effective than indoor heaters because outdoor heaters have to work harder to heat the whole patio (cold weather will undo any work already done) while indoor heaters don't have to worry about varying temperatures.
heaters are there to heat you and coolers are there to cool you
Outdoor heaters need to be safe with different types of weather, so they would be different than indoor heaters. They are both effective, but never use an indoor heater outdoors.
The most energy-efficient options for home water heaters are tankless water heaters and heat pump water heaters. Tankless water heaters heat water on demand, reducing standby energy loss. Heat pump water heaters use electricity to move heat from the air or ground to heat water, making them more efficient than traditional electric water heaters.
Outdoor patio heaters can be purchased at a variety of locations. The best place to start looking is a hardware store. Department stores such as Walmart also sometimes carry outdoor patio heaters, depending on the season.
