Helps to evenly distibute the heat

We use the fireplace to help heat the house.  Without the fan it did an OK job, but with the fan it really helps the heat to go out into the room more.  We did have to make a slight modification to the fireplace by adding a switch, but it nothing that my husband wasn't able to do on his own.  This has done exactly what I thought it should do

An elegantly simply solution to a getting a low heat simmer on a stovetop, especially with gas burners. Expensive gas ranges turn off and restart gas burners to get a low heat setting, this plate simply buffers the heat from a burner, what a great idea. Perfect for warming sauces without burning them. This plate was much cheaper than others I saw and is cast iron. I had no problem with the finish smoking on first use as noted in other reviews.

For riding in Arizona you need some help with the heat and this works.  Diffidently helped cool me down when riding.

I installed these in my up stairs rooms that were poorly heated/ac and it made a big difference. It also helps to close off or reduce air volume on other vents where you have rooms you don't use as much.

The Kuhn distributes the heat evenly across the surface of the burner.  No more hot spots.  Two thumbs way up!

Seems provide a nice cooling massage for hot spots.  Smells fine, too

Distributes heat evenly and a breeze to clean up.  We use them on a gas stove but I imagine these perform well on electric stoves as well.  I'd purchase these again if needed.

These briquet holders don't last more than several seasons but they are the best for concentrating or spreading out the heat in your Weber grill.  If you want indirect heat, just put the two holders in the outer perimeter of the grill.  If you want to concentration the heat, put them close to together in the center.  I have even used it for smoking meat, using a smoke box between the two briquet holders, placing soaked hickory chips in the smoke box.

Glad I was able to use this with ease. Blade does over heat, so make sure to order coolant spray for the blade. Two speeds for convenience.

brings enough heat to the table without scorching you. A few drops to dishes can really kick it up some.

These bars increase the heating rate and high temps available.  I should have made this change years ago.
The expense seems worthwhile.

This little guy makes a big difference in helping to heat the room.  You would not think so but it really helps.
Starts up at about 130 F Has a cool over heat protection feature built in, when it gets too hot it lifts the base up a little to help keep it form over heating via a bi-metal strip.

some trouble fitting it in but worth the effort; doesn't put out as much heat as we hoped for

I like all the tips that this has, and it works really well, but I wish there was a way to keep the heat set at a certain temperature. It gets hotter the longer it is plugged in, which doesn't leave a lot of time to get intricate work done before you have to unplug it to let it cool because you can't hold the handle when it has been plugged in for too long.

Seems to help quite a bit with heat coming through the window in the summer. Also cuts down the light.

This has worked great at keeping the pool heat in and warming it up a few degrees.

The item was very easy to install,and made a big difference in heat retention in our home. I would recommend using one.
