There are paints that can handle temperatures that high, but normal house paint is not going to do it and will just quickly burn off (possibly releasing toxic fumes in the process). You will need to get a special high temperature paint, and even for those 1500 degrees is fairly extreme. Rustoleum makes a spray paint for use on automobile engines that can allegedly tolerate up to 2000 degrees (Fahrenheit; about 1100 degrees Celsius) "intermittently", but I don't have any personal experience with it and can't say how well it would do at 1500 degrees for an extended period of time. Also, a lot of high heat coatings require "curing" at an intermediate temperature (say, 500 degrees) for some period of time; I don't know how well they'd work going from freshly painted straight to 1500 degrees.
A fireplace grate isn't necessary but they are beneficial. They help keep the wood together and aim the heat out of the fireplace instead of up. They also allow your fire to breathe.
Fireplaces are generally pretty bad at heating. A set of doors for the fireplace can help. A heat exchange grate with a blower can get more warm air out into the room. The best solution is also the most expensive- a properly installed fireplace insert. This is basically a wood stove that fits into the fireplace.
You must rough up the old finish, use sandpaper. Then apply the heat resistant paint
A 1500 watt Electric fireplace will heat 400 square feet to a comfortable temperature within 30 minutes. Thus you won't have to turn on the house heat or be able to keep it at a lower setting. A Electric Fireplace cost about $30 a month to run 5-6 hours a day.
The fireplace's heat is an example of radiation.
A grate heater can be used to make a wood burning fireplace more efficient at heating a home. Fireplaces often use electric fans to blow the heat into the room. Grate heaters use much less electricity than traditional electric fans.
Fireplace
Heat cast forward out of a firepalce is called radiant heat and it the only usable heat that a fireplace can create The wasted heat that a fireplace creates is called combusion heat that rises up the chimney.
Check and see if your fireplace has heat vents on the sides or above the firebox, and that they are open.
The function that a fireplace fan serves is to distribute heat throughout the room that the fireplace is in. A fireplace fan is ideal because it's probably not safe to sit too close to a fireplace.
The main thing that one should do to make sure that heat is not being lost through the chimney of a fireplace is to always close the damper when the fireplace is not in use. In addition, you can also use a fireplace door or cover to prevent additional heat loss.
