Different Types of Water Heaters & Their Costs
Choosing the right type of water heater is crucial, as it affects both the upfront cost and long-term savings. Below are the most common types of water heaters along with their estimated replacement costs.
1. Traditional Tank Water Heaters: Cost & Benefits
Understand the costs and benefits of traditional tank water heaters, including upfront pricing, energy efficiency, and maintenance factors.
Tank water heaters store hot water in a large tank, making them the most common type found in homes. The cost of a new tank water heater varies based on size and energy efficiency:
40-gallon water heater replacement cost: $300 - $900 (excluding installation)
50-gallon water heater replacement cost: $400 - $1,200
Hot water tank replacement cost: Varies based on material and energy efficiency.
Larger households often require bigger tanks, increasing costs. Additionally, high-efficiency models cost more upfront but save money on energy bills over time.
2. Tankless Water Heaters: Cost & Efficiency
Learn how tankless water heaters provide energy efficiency and long-term cost savings while eliminating the need for a storage tank.
Also known as on-demand water heaters, these systems heat water only when needed, making them more energy-efficient. However, they come with a higher upfront cost:
Tankless water heater price range: $800 - $3,000
Longer lifespan and space-saving design make them a great long-term investment.
Instant water heater vs storage water heater: Tankless heaters heat water on demand, while tank models store hot water for later use.
How much is a new water heater? A new tankless unit typically costs more than a storage water heater but saves energy in the long run.
3. Heat Pump Water Heaters: Cost & Savings
These energy-efficient systems use electricity to transfer heat instead of generating it directly:
Heat pump water heater cost: $1,200 - $2,500
Ideal for moderate climates and homes with sufficient space.
Best water heater for home: Heat pump water heaters offer significant energy savings in the long run.
4. Solar Water Heaters: Eco-Friendly & Cost Breakdown
Using solar energy, these environmentally friendly water heaters have higher upfront costs but offer substantial long-term savings:
Solar water heater price range: $2,000 - $5,000
Installation costs can be higher due to additional structural requirements.
Affordable water heater services: While solar systems are pricier upfront, incentives and rebates may help reduce costs.
