Is ventilation necessary for water heaters?

• <div><p>Not all <a href="https://www.angi.com/articles/types-of-water-heaters.htm">types of water heaters</a> require a venting system. Electric tankless water heaters don’t use natural or propane gas, so no venting is required. Instead, they use electric burners to heat water quickly and efficiently. However, any system that does use gas or propane will require ventilation. </p></div>

How often should electric water heaters be replaced?

• <div><p>Electric water heaters typically last 10 to 20 years, though proper maintenance can extend their lifespan. If your unit is over a decade old and showing signs of inefficiency—such as higher energy bills, frequent repairs, or leaks—replacement is a smart investment. Tankless models last over 20 years, which can make them a longer-lasting alternative to traditional tank water heaters.</p></div>

Q: Should I replace my 20-year-old gas water heater?

• <div><p>If your gas water heater is over 20 years old, it should be replaced. Gas water heaters can last up to 12 years and while they can exceed this expectancy if well-maintained, a heater that's 20 years old would require replacement. The heater is unlikely to run as efficiently as a new model and could be more expensive to do so.</p></div>

Q: How do you know when your electric hot water heater is going out?

• <div><p>Signs your electric water heater is failing include inconsistent water temperature, reduced hot water supply, longer heating times, or discolored water (rusty or cloudy). Unusual noises like popping or rumbling suggest sediment buildup, while leaks or corrosion around the tank signal structural damage. If your unit is over 10 to 15 years old and experiencing frequent issues, it may be time to replace it.</p></div>

Q: Can a heat pump water heater work in colder climates?

• <div><p>Yes, a heat pump water heater can work in colder climates but it&rsquo;s much more effective where it&rsquo;s warm. The reason is that the heat pump needs ambient warmth in the air to compress. The less warmth, the more compression required, thus using more electricity and offsetting the energy-efficient benefits. </p></div>

Ashley and her team did a great job on our drywall repair, trim, and paint project after we had water damage from flooding in our basement. The work was done in a timely manner and the work itself was top notch. We would definitely hire Coastal Finish again for other projects!

"We pay yearly but we have this is included with our rental property. They are pretty good on most things. We had a hot water heater replaced and they did an excellent job on that. They are very quick on their response. They dont come out here. It is all done on the internet. I just like the idea that one time service charge is so much better than trying to hiring someone to come in. It is more about convenience. It pays for itself."
