Large families that use a lot of hot water will put more stress on the unit, potentially shortening its lifespan. Regular maintenance and repairs can lengthen the unit&rsquo;s lifespan.</p></div>

Q: How long do heat pump water heaters last?

• <div><p>Traditional gas or electric water heaters last an average of six to 11 years. However, with excellent maintenance, they can last up to 15 years. Heat pump water heaters, on the other hand, last an average of between 12 and 15 years and potentially longer with proper maintenance. In both cases, your home's water quality can be a determining factor regarding the lifespan of your water heater.</p></div>

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

• <div><p>The average<a href="https://www.angi.com/articles/how-much-does-water-heater-installation-cost.htm"> cost to replace a water heater</a> is <b>$1,325</b>. How much your replacement heater costs depends on the type, size, and complexity of installation. Gas and electric heaters may cost a similar amount out of pocket, but one type may cost more to operate than the other, depending on the cost of utilities in your area. </p></div>

Q: Are hot water heater expansion tanks necessary?

• <div><p>While many older homes don&rsquo;t need hot water heater expansion tanks, they&rsquo;re necessary in most newer homes and are required by building codes. These tanks are required by code in areas where there are backflow preventers or pressure regulators on the incoming water pipe between the public water pipes and the water heater. However, tankless water heaters don&rsquo;t require expansion tanks.</p></div>

Q: Can you vent a gas water heater out the side of the house?

• <div><p>You can and should vent the gas from your hot water heater to the outside of your home. Traditionally, these gases were vented back to other gas appliances, like stoves or furnaces, but many jurisdictions have outlawed this practice due to the risks it provides. </p><p>Most water heaters today use atmospheric venting that exhausts the gas out of the home through a pipe.</p></div>

Very satisfied with the Beachfront, they carried their water on the truck, and we recommend them to anyone who doesn't want to use their water pump. Removed all green algae and moss, and the house looks clean along with the decks!

They do a really really good job. I have several places that have standing water and I have not had any problems since they started spraying. They use stuff that is non-harmful to pets and they always close my gates.
