Electric tankless water heaters are designed to be installed indoors in the garage, basement, or interior wall. Both natural and propane gas tankless water heaters have indoor and outdoor models. Indoor models can also be installed in the garage, basement, or the exterior wall’s interior side to provide venting.
Secondly, are tankless propane water heaters more efficient?
According to Energy.gov, “For homes that use 41 gallons or less of hot water daily, demand (or tankless) water heaters can be 24% to 34% more energy efficient than conventional storage tank water heaters.” Tankless water heaters (if gas-fired) will save homeowners over $100 annually the longer they remain in service.
Keeping this in consideration, can you have a tankless water heater with propane?
Tankless water heaters can run on propane (LP gas). Propane tankless water heaters provide instant hot water on demand, just like natural gas models. Propane can be used where natural gas utilities are not available.
Can you run out of hot water with a tankless water heater?
Although a tankless system can’t run out of hot water, it can still be overwhelmed with demand. A single tap won’t do this: run that single shower all you want, you’ll keep getting hot water.
No. Unlike gas tankless water heaters and gas traditional tank style water heaters, electric tankless water heaters do not require any venting.
MYTH 3: Tankless requires complicated venting.
Unlike traditional storage tank water heaters, propane tankless units do not need to be vented through the roof. Their combustion fan blows exhaust from the units horizontally.
120-gallon propane tank: If you use propane in one or two appliances, such as a range, fireplace, clothes dryer, tankless water heater this might be your tank. 250-gallon propane tank: This tank could be used for whole-house heating for a small home, typically 1200 sq. feet or less.
Propane is considered a more efficient fuel than natural gas. It costs $350 per year to run a propane tankless water heater, so it’s slightly more expensive than a natural gas heater.
The main disadvantage of tankless water heaters is their upfront cost (unit and installation) is significantly higher than tank-style heaters. Including installation, tankless water heaters cost 3 times more than tank-style water heaters on average.
