A hot water tank stores and heats a set amount of water (commonly 40–60 gallons for homes). It’s a simple, cost-effective solution that works well for households with steady hot water needs.

Things to Consider

• Average lifespan: 8–12 years

• Uses more energy since water is heated continuously

• Can run out of hot water if demand is higher than the tank size
