"My hot water heater stopped working. As it was 8 years old, I thought I would have to buy a new one. But when Guy from Anchorage Plumbing & Heating arrived, he said he could fix it, and he did. I have hot water again, and I didn't have to buy a new one. Saved me a lot of money. This is the company I will use from now on for plumbing and heating problems."
"Moore removed and replaced my water heater in mid November. First class work performed and no issues with it since. Had the duct work cleaned for the first time and while pricey worth knowing they’re clean of debris."
It’s important to find the type of water heater that fits your needs and budget. Depending on the type of water heater, size, brand, and the type of energy you use to heat the water, costs range from a few hundred dollars to several thousand.
Some of the most common types of water heaters include:
Electric: $600–3,500
Gas: $700–$2,700
Propane: $700–$2,500
High efficiency: $1,500–$3,000
Indirect: $1,200–$3,500

While not all homes require a hot water heater expansion tank, they are necessary in most newer homes and are often mandated by local building codes. Codes typically require an expansion tank if your plumbing system is a 'closed-loop' system, which often includes a backflow preventer or pressure regulator on the main water line. Some municipalities have specific requirements. Installing an expansion tank on a closed system is crucial, as it prevents excess pressure that can damage your water heater and other appliances, potentially shortening their lifespan. However, tankless water heaters do not require an expansion tank.
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.
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.
Most water heaters today use atmospheric venting that exhausts the gas out of the home through a pipe.
