Around here NG heat is about 1/3 the cost of electric resistive heat or propane. A mini-split heat pump heats at about 1/3 the cost of resistive heat (that's where the 300% efficiency comes from). So the actual running cost to heat with NG or heat pump is about the same. But a mini split also cools. I dont know how much it costs to install a vented NG heater but a mini split for 350 square feet is a DIY project. And they have wifi control. You're at work, get off in 3 hours and want to use the shop...just use the app on your smart phone to tweak the temp.
I hope to install a mini split this summer. I need cooling as well as heat and don't have easy access to NG (gotta run a line and install a vent, not DIY for my skill set). Mini split needs a 3" pass-through hole and plugs into a 120ac outlet, I got those skills.
