Some portable heaters are also available which are similar in principle and much more convenient to set up. They do not have as much power as the standing heaters do and are less expensive, some costing just under $30.00.
Look For A Safety Switch
Safety is another issue. Many modern models have a tilt switch, which automatically turns the device off if it is tipped over, and an automatic shut off in case you forget to turn it off manually. This is a great feature which affords peace of mind.
