Which Type of Water Heater is Best for Your Home?

Hot water is one of those everyday comforts you rarely think about—until you don't have it.

Whether your current water heater is failing or you're looking for a new, energy-efficient solution, choosing the right system for your home is an important decision. Because water heaters offer a variety of features, efficiencies, and installation requirements, it's worth taking the time to understand your options before investing in a new or replacement system.

In this blog post, our home comfort specialists provide an overview of the four most common types of residential water heaters to help you determine which is best for your home.

Traditional Tank Water Heaters

The most common choice for homeowners is a traditional storage tank water heater. It stores 30 to 80 gallons of hot water, which is always available whenever you turn on the tap.

Benefits

• Lower upfront equipment and installation costs

• Reliable performance for households with higher simultaneous hot water demands

• Familiar technology that most homeowners are comfortable with

  
  

Considerations

This type of traditional system requires more floor space than some newer options, and because the water is always kept hot, it consumes energy even when no one is using hot water.

However, for many homeowners, a traditional tank water heater remains a dependable and cost-effective solution.

Tankless Water Heaters

Tankless, or “on-demand,” water heaters only heat water as it is needed. Instead of storing hot water in a tank, these units rapidly heat water as it passes through the system.

Benefits

• Endless hot water for normal household use

• Higher energy efficiency by eliminating standby heat loss

• Compact, wall-mounted design requires less floor space

  
  

If you’re looking to maximize efficiency and save space, a tankless water heater may be a good option for you.

Considerations

Installation costs are typically higher than those of a tank water heater. Electric models may require electrical service upgrades, while gas units require dedicated venting. 

Depending on household demand for hot water, running multiple showers or appliances simultaneously may exceed the unit's flow capacity.

Indirect Water Heaters

If your home already uses a boiler for heating, an indirect water heater can be an extremely efficient choice.

Rather than heating water independently, these systems use your home's boiler to warm water stored in a well-insulated tank.

Benefits

• Outstanding efficiency during the heating season

• Lower operating costs when paired with an existing boiler

• Reliable supply of hot water

  
  

Considerations

An indirect water heater relies on your home's boiler and, because it requires a storage tank, it may not operate as efficiently in the summer (when your heating system would otherwise remain off).

For many New England homeowners with hydronic heating systems (which heat with hot water rather than warm air), indirect water heaters offer an excellent balance of comfort and efficiency.

Heat Pump (Hybrid) Water Heaters

Heat pump or hybrid water heaters are becoming increasingly popular due to their exceptional energy efficiency. Instead of generating heat, they pull warmth from the surrounding air and transfer it into the water.

Benefits

• Among the most energy-efficient water heaters available

• Can cost significantly less to operate than conventional electric water heaters

• Often qualify for ENERGY STAR® incentives and local utility rebates

• Help dehumidify basements and utility spaces

  
  

Considerations

In addition to costing more, heat pump water heaters need more installation space because they draw heat from the surrounding air. For this reason, they’re generally best suited for basements, garages, or utility rooms.

If you’re focused on reducing your long-term energy costs, a hybrid water heater may be a good option.

Which Water Heater Is Right for You?

Every home has different hot water needs, so the "best" water heater depends on your existing heating system and your household budget.

A heat pump water heater may be the right choice if:

• Lower utility bills are your top priority.

• You have space for installation.

• You're planning for long-term energy savings.

  
  

A tankless water heater may be ideal if:

• You want endless hot water.

• Space is limited.

• Your household only has a moderate simultaneous hot-water demand.

• 
  

An indirect water heater makes sense if:

• Your home already has a boiler.

• You live in a colder climate such as Massachusetts or Southern New Hampshire.

• You want to maximize the efficiency of your existing heating system.

  
  

A traditional tank water heater remains a great option if:

• You're replacing a failed water heater quickly.

• You're working within a budget.

• Your household often demands large amounts of hot water at the same time.
