Hot Water Tanks 101

Apr 30, 2025

Thinking about a new hot water tank? At Service Pro Plumbing here in Campbell River, we get it — there are a lot of options out there. Here’s a quick guide to help you make sense of it:

Gas vs Electric vs Tankless

  • Gas Tanks heat water fast and are great if you already have gas service.

  • Electric Tanks are easy to install and perfect for homes without gas hookups.

  • Tankless Systems (also called on-demand) heat water as you need it — no big tank sitting in your space!

How Long Do Hot Water Tanks Actually Last?

Most hot water tanks have a lifespan of 8 to 10 years. After that, they’re at higher risk of leaks and failures — and many insurance companies are now requiring homeowners to replace tanks once they hit that 10-year mark.

If your tank is getting close to that age, it’s a good idea to start thinking about a replacement before you get a surprise puddle in your basement.

Sizes for Every Home

  • Standard: 40–60 gallons — the sweet spot for most families.

  • Space Savers: Ideal for smaller homes, suites, cabins, RVs, or single-use areas.

  • Larger Units: Ideal for those who often have multiple hot water sources running at once and are not interested in a tankless unit, which occasionally struggles with multiple uses.

No matter your space or water needs, there’s a tank size that fits.
