What Type of Water Heater Is Best for Your Home?

Choosing the right water heater depends on your household size, energy preferences, and long-term efficiency goals. Here’s a quick breakdown of your options:

Traditional Tank Water Heaters

These systems store hot water in a large tank—typically ranging from 20 to 80 gallons. They’re easier and less expensive to install, making them a great choice for many families.

Tankless Water Heaters

Also known as on-demand systems, these heat water only as you need it. They cost more upfront but save energy and lower monthly utility bills.

Choosing Between Gas & Electric Water Heaters

Your home’s access to utilities and your energy rates will determine which fuel source is best:

• Gas water heaters tend to cost more initially but offer lower monthly operating costs—ideal for homes already equipped with gas lines.
• Electric water heaters are usually more affordable upfront and may be a smart choice where gas isn’t available or cost-effective.

Need help deciding? Our experts will walk you through both options during your in-home consultation.

How Big Should Your Water Heater Be?

Tank-style heaters are available in a variety of sizes. The most common is 40 gallons, which suits an average household—but larger families may require 50+ gallons.

The size of your tank affects both installation cost and energy usage. Our licensed plumbers will assess your water usage habits and help you size your unit correctly, so you’re not overpaying for capacity you don’t need—or running out of hot water too soon.
