DH put ours in. We bought an electric fireplace from Home Depot. It was cheaper to get a whole kit with the cabinet than just the firebox. I think we paid less than $200. The firebox unit was separate from the cabinet which we gave away. DH put in a separate breaker for the dedicated circuit, installed an outlet and we were set. It was a good heat solution for us last winter when we were at a park that didn't meter electricity. i'm not sure how it would have penciled out if we were being charged for usage. Yes, it does take up more room than an equivalent space heater, but if you want a fireplace, you want a fireplace. Congrats on the new fifth wheel.
