Where can I find an Electric Fireplace?

My aunt wants an electric fireplace to put in front of her real fireplace. Where can I get an affordable, and efficient at warming a room up one? Walmart? Target? What is the price range and do I need dimensions or is it one size fits all?

Answer
My father put an insert like that in his cobble stone fireplace. I must admit is is handy to start it with a flip of a switch and it put out some pretty good heat. He bought it through a local fireplace retailer.

When we install them out of our shop we put in a chimney balloon to plug the flue first then install the insert and hook it up to the electrical. The installation is pretty simple. If you can lift 40 lbs or so you can DIY it.

Would it pay to put a propane fireplace insert in my home?

My home is 4 yrs old. It is heated by oil (hot water), I have an existing wood burning fireplace. Would it be economical to put in a propane fireplace log insert, too compliment the oil heat? The house seems to heat really hard. The house is 1800 sq ft. We seem to fill up with oil (half tanks 130 gallons) every month in the winter. Any help is appreciated.

Answer
Propane is not a whole lot cheaper than oil. You may want to get an electric radiant heat heater instead. They make wood burning inserts that you can install in your fireplace. Some models have a heat chamber with a fan to force the heat into the room. Most wood burning fireplaces (without the insert) just shoot most of the heat up the chimney. With an insert you can better regulate the fire for a slower burn. You use less wood and stop the heat that is in the room from going up the chimney. Between the insert and a radiant heater used in the rooms your are in most, you should cut down on your oil consumption.
Good luck, stay warm and be safe !

How can I convert several small, battery operated lights to run from an ac outlet?

Erica

My girlfriend and I recently moved to Texas. Our apartment has a fireplace but we have no plans to use it to actually light fires. Instead of having a dark, black pit in our living room, she wants to use flameless candles to illuminate the area. Instead of switching some 20 odd candles on one at a time and using battery power to run them, we would like to wire all of the flameless candles together, in parallel, to a wall outlet so that we only have to flick the switch and we will have an instant fire in our fireplace, without using batteries at all.

I can handle splicing wires, it's just the details that get the better of me, i.e. math.

I know that I need an adapter, but I don't know how to determine what size adapter I need.

Once I figure out what size adapter, what measures can I take to allow me to add or take away lights from the circuit as I see fit?

At the moment we have 3 types of candles: the large type requires 3 double A batteries. The medium type come wired together in twos, They use 3volt batteries. The small uses a 3 volt battery as well.

I have access to a multimeter but I can't figure out how many amps something like this uses. Also, I am under the impression that while adapters have to be specific to the voltage, it's usually better to overestimate on current. Working under this presumption, would my circuit work if I were to find an adapter rated for my circuit's voltage but rated for the highest number of amps?

If someone could give me some instruction so that I know how to adjust my system in the future if I need to change anything, that would be awesome.

Thanks!

There's a far easier way.
Electric logs. Vintage one on sale for $15 now on EBAY.
It uses a 25 watt bulb.
No need to re-invent the wheel (or fire either!)
