How much does water expand in a water heater?

• <div><p>Water expands when heated and also when freezing. When water is heated, it expands by around 4%. For a full water heater, this is one of the main reasons malfunctions occur—the hot water has nowhere else to go but out. Due to the constant expansion and reduction in volume, it’s recommended (required in most places) that an expansion tank be installed. </p></div>

Do both my boiler and water heater need their own expansion tank?

• <div><p>Unless they are connected to the same system, boilers and water heaters will both need their own expansion tanks. The only case they wouldn’t have separate expansion tanks is if the boiler is pulling double duty and managing a heating system while also supplying hot water for a home. In which case, you may not need a hot water heater. </p></div>

How much water should come out when draining a water heater?

• <div><p>The average water heater holds between 40 and 60 gallons, but the exact amount of water that comes out during draining will depend on your unit’s capacity. The amount of <a href="https://www.angi.com/articles/how-long-drain-water-heater.htm">time it takes to drain a water heater</a> averages from 10 to 30 minutes.</p></div>

Q: Does installing a water heater yourself void the warranty?

• <div><p>Several things can void the warranty for your water heater. Many water heater manufacturers state that installing your own will void the warranty. However, even if you get away with performing the task yourself, incorrect installation, lack of a building permit, and improper repair work, regardless of licensing status, can all render your water heater unprotected by both the manufacturer's warranty and any installation warranties. </p></div>

Q: How much does it cost to install a water heater?

• <div><p>The average cost to install a new water heater is approximately $1,300, with a typical price range between $880 and $1,800. The final cost depends on several factors, including the type and size of the unit, its location and accessibility, and the amount of labor required. For example, installing a unit in a tight space like a crawl space can increase labor costs. The type of water heater significantly impacts the price: while a conventional gas heater might cost less than $1,000, tankless models can cost around $2,600 to install (and up to $3,500), and solar heaters can cost upwards of $3,700. Other factors that can affect the total price include the fuel type, vent system requirements, permits, and whether any additional plumbing work or repairs from previous water heater damage are needed.</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.
