How big is the Giantex 28.5" Insert?
It measures 28.5"W x 6"D x 21"H and weighs 25.7 lb. Measure your firebox opening at the front and the back before you order, and leave at least half an inch all round.
How much does the Giantex 28.5" Insert heat?
The heater runs at up to 1,500 W, about 5,118 BTU. That is supplemental heat for one room, not a furnace. At 16 cents per kWh, running it on full costs about 24 cents an hour. You can also run the flames alone without heat, which costs only a few cents a day.
Does the Giantex 28.5" Insert need a special outlet?
No. It plugs into a standard 120 V household outlet. Plug it straight into the wall, not into an extension cord or power strip, and keep it on a circuit without other big loads like a space heater or microwave.
What warranty comes with the Giantex 28.5" Insert?
We found no written warranty on the listing or the maker's site. Amazon's return window still applies, so test the heat, the remote and every flame setting as soon as it arrives.
How much does the Giantex 28.5" Insert cost?
The last price we saw was $136. Electric fireplace prices move a lot, with the biggest drops around Black Friday and after New Year, so check the current price.
