Questions homeowners ask
How much should I expect to pay to replace my water heater?
For a straight 50-gallon gas swap, about $1,200 to $2,000 fitted. Electric is a little less. Going tankless roughly doubles it, mostly because of the gas and venting work rather than the unit. A same-day emergency call-out adds around a fifth on top.
How much should a new 40 gallon water heater cost?
Roughly $950 to $1,650 installed for a gas unit. The gap between 40 and 50 gallons is small, usually a couple of hundred dollars, so if the household has grown since the last one, it is rarely worth going back down in size to save money.
What is the average labor cost to install a 50 gallon gas water heater?
Labour is close to a third of the bill, so about $480 on a typical $1,600 job. The unit itself is the largest single line at roughly 40%. Quotes that look unusually cheap have often left out the permit, the expansion tank or hauling the old one away.
How much does Home Depot charge to replace a hot water heater?
Big-box replacement is subcontracted to local plumbers, so the figure lands in the same range as calling one directly. The difference is the unit, you are quoted on what the store stocks. Worth getting one independent quote alongside it, particularly if you are considering a heat pump model, where rebates can change the maths entirely.
