![]() ![]() How many gallons a water heater tank holds (30 to 80 gallons) determines the size and the price increases with size. However, a tankless water heater can save you up to 25% on utilities. You’ll pay more for labor as installation can take up to 10 hours. Tankless (Covered Above)Īlthough tankless water heaters are smaller than tank-style units (which hold 30 to 80 gallons of water), they are more difficult to install. Consider each factor and what’s best for your needs. Various factors affect the cost of replacing or installing a new water heater. As the gas burns, air heats up and vents out of your house through a vent stack above the unit. This system is based on the idea that hot air rises over the cooler surrounding air. Natural and propane gases create carbon monoxide as they burn, creating a potentially serious health hazard if not vented properly.ĭirect venting: Adds $500-$1,000 only if you’re converting from electric to gas. This system uses a powered fan to push exhaust air out of your home. Plus, you’ll add an additional $300-$500 for wiring and electrical. Power venting: Adds $300-$600 to the unit’s price. Power venting a water heater costs about $500 to $1,000 more than a passive or direct vent system. Propane and oil-fired types offer an alternative to electricity and natural gas for rural and off-grid homes. Propane and oil-fired water heaters both fall on the expensive end of the spectrum at $1,000 to $3,000 for the unit alone. However, electrical types, whether tank or tankless, make better choices for small apartments or confined areas since they don’t require make-up air or venting. Although natural gas units cost more up front and they’re less energy-efficient, the high price of electricity in most parts of the country still makes gas the cheaper long-term choice. The internal heating comes either from an electrical coil, much like a stove top coil, or via a gas pilot light. On average, natural gas fired units cost $100 to $200 more than electrical types.
