Can you switch to a tankless water heater from a heater with a tank?

• <div><p>Yes, you can replace a current tank water heater with a tankless model or vice versa. If you’re maintaining the same fuel source—gas or electricity—the switchover should be smooth. A conventional tank requires open floor space, while a tankless model can be wall-mounted. If you’re switching to a tank water heater, you might need to clear space for it. Gas-powered tankless water heaters need a large volume of gas when they start running to heat the water instantly. You might need to increase the size of the gas line when going from a tank to a tankless model.</p></div>

Q: How heavy is a water heater?

• <div><p>An average-sized empty water heater weighs around 150 pounds. Tankless water heaters are much lighter, weighing between 10 and 50 pounds. The smaller size and added convenience come at a price, though&mdash;tankless water heaters average about twice the price of their traditional counterparts.</p></div>

Q: Which types of gas appliances might require installation or replacement services?

• <div><p>Examples include gas stoves, ovens, and water heaters. Confirm with your provider for specific items.</p></div>

Q: What is involved in converting a gas water heater to an electric one and how much does it cost?

• <div><p>Yes, you can convert a gas water heater to an electric one, but it is a complex process. You will need to ensure there is adequate power for the new electric unit, as they require more power than gas models. The project also involves safely closing off the gas lines and ventilation, and some cities may require a permit for the conversion. The cost can range from $1,500 to $4,100, depending on the installation scope, plumbing and electrical work, and the water heater model. For an accurate quote, it's best to contact a local professional. Also, be aware that your monthly utility bills may increase after the conversion, as natural gas is typically cheaper than electricity.</p></div>

Q: How do hot water heater expansion tanks work?

• <div><p>When the water expands in a hot water heater, it puts pressure on your hot water pipes and can cause leaks or a rupture in the hot water tank under certain conditions. Pipes or water heaters may split due to the pressure where there is a backflow preventer that prevents the hot water heater from diffusing pressure by releasing water back to the public water line.</p><p>In these scenarios, a hot water heater expansion tank provides a place for the hot water heater to relieve pressure and prevent bursts and leaks.</p></div>

This was a big job. It took them several months to get the crews out to do the work, but once they started, it all moved very quickly. They had to do some extra work because of water damage discovered when they removed the old siding, but the charge for repairs was lower than expected.
