Choosing the right water heater for your home is an important decision that impacts your energy bills, hot water availability, and long-term maintenance costs. At Home Team Plumbing, we offer a wide range of tankless and tank water heaters from trusted brands like Stiebel Eltron, Rheem, Eemax, Rinnai, Navien, and Bradford White.
In this guide, we’ll compare tankless vs. tank water heaters, highlight the key differences, and help you determine which one is the best fit for your home.
1. Understanding the Two Types of Water Heaters
What is a Tank Water Heater?
A tank water heater stores and continuously heats a large amount of water, typically ranging from 30 to 80 gallons. The water remains hot and ready for use, but once the tank is emptied, you’ll need to wait for it to refill and reheat.
Key Features:
- Heats and stores water 24/7.
- More affordable upfront but can lead to higher energy costs.
- Requires significant installation space.
What is a Tankless Water Heater?
A tankless water heater heats water only when needed. Instead of storing hot water, it quickly heats water as it flows through the unit, providing endless hot water on demand.
Key Features:
- Energy-efficient since it only heats water when necessary.
- Compact design saves space.
- Higher upfront cost but lower long-term energy bills.
