Water Heaters questions, answered by experts

Water heater replacement costs around $1,300, but a total install will depend on a few factors. Solar heaters can cost upward of $3,700, while conventional gas heaters may cost less than $1,000. Tankless water heaters, common in apartments and homes without much space, cost around $2,600 to install. Expect the cost to increase significantly if new plumbing is required, or if there is damage from a previous water heater malfunctioning. 

A larger heater requires a larger breaker—unless there’s one already installed. The longer answer to this question is more nuanced. Do you place demands on the heater at the same time as running other heavy-duty appliances like ovens and washing machines? Do you live in an older home that may not have considered the higher electrical demands we have now? Breakers need to be sized at 125% of the load. To find that load, you should call a local electrical pro.

Converting a gas water heater to an electric one can cost between $870 and $4,100, depending on the installation scope, plumbing and electrical needs, and the water heater model. However, it’s always better to contact a local pro for a more accurate quote. Also, since natural gas is cheaper than electricity in most regions, you should prepare yourself for a higher monthly cost after the initial conversion.

Signs that your water heater may explode include rust-colored water coming from hot water taps, the smell of sulfur or rotten eggs coming from the water, shaking or rumbling in the tank, and a leaky temperature and pressure valve. If the water heater feels excessively hot to the touch, it could also indicate the prospect of an explosion. If you suspect your water heater might explode, call a pro immediately to address the problem.

Newer models are packed with newer technologies that decrease energy consumption and increase output, giving you more bang for your buck in more bills than one. 

If you’re trying to decide whether you want to repair or replace your new heater, consider factors like your utility bills, repair costs, and even your carbon footprint to help you decide whether it makes sense to buy a new one instead.
