Different Types of Water Heaters

May 19, 2023

Are you in the market for a new water heater but feeling overwhelmed by the many options available? In this blog post, we’ll break down the pros and cons of five different types of water heaters to help you make an informed decision.

Gas water heaters:
Gas water heaters are one of the most common types of water heaters, and for good reason. Here are the pros and cons:

Pros:

Fast heating: Gas water heaters can heat up water quickly, making them a convenient choice.
High hot water capacity: Gas water heaters can supply hot water for multiple appliances simultaneously, making them ideal for households with high hot water demand.
Low operating costs: Gas is typically cheaper than electricity, making gas water heaters a cost-effective choice.
Long lifespan: Gas water heaters can last up to 15 years, which is longer than some other types of water heaters.
Reliable: Gas water heaters are known for their reliability, as they can continue to operate during power outages.

Cons:

Higher upfront costs: Gas water heaters can be more expensive to install than electric water heaters.
Requires ventilation: Gas water heaters produce exhaust gases that need to be vented outside, requiring additional installation steps.
Potential safety concerns: Gas water heaters produce carbon monoxide, which can be dangerous if not vented properly or if the system malfunctions.
Can require more maintenance: Gas water heaters need to be serviced regularly to ensure they are functioning properly and safely.
Not environmentally friendly: Gas water heaters produce greenhouse gas emissions, making them less environmentally friendly than some other types of water heaters.

Tankless water heaters:

Tankless water heaters are becoming increasingly popular due to their energy efficiency and space-saving benefits. Here are the pros and cons:

Pros:

Energy-efficient: Tankless water heaters only heat water when needed, making them more energy-efficient than traditional tank-based heaters.
Space-saving: Tankless water heaters are smaller than traditional tank-based heaters, freeing up space in your home.
Long lifespan: Tankless water heaters can last up to 20 years, which is longer than traditional tank-based heaters.
Low maintenance: Tankless water heaters require very little maintenance, as they have few moving parts.
Endless hot water supply: Tankless water heaters can provide an endless supply of hot water, making them ideal for households with high hot water demand.

Cons:

Higher upfront costs: Tankless water heaters can be more expensive to install than traditional tank-based heaters.
Possible lag time: Tankless water heaters can take a few seconds to heat up water, which can be inconvenient if you need hot water quickly.
Climate-dependent: Tankless water heaters can be less efficient in colder climates, as they need to work harder to heat water.
Requires professional installation: Tankless water heaters require professional installation, which can add to the overall cost.
Potential hard water issues: Tankless water heaters can be more susceptible to hard water buildup, which can reduce their efficiency and lifespan.

Electric water heaters:

Electric water heaters are a popular choice for those who don’t have access to natural gas. Here are the pros and cons:

Pros:

Easy installation: Electric water heaters can be installed in most homes without requiring additional ventilation.
Low maintenance: Electric water heaters require very little maintenance, as they have no moving parts and no pilot light.
Energy-efficient: While not as energy-efficient as tankless water heaters, electric water heaters are more efficient than tank-based heaters, as they do not lose heat through the flue.
Low upfront costs: Electric water heaters can be less expensive to install than gas or tankless water heaters.
Safe: Electric water heaters do not produce carbon monoxide, making them safer than gas water heaters.

Cons:

Slow heating: Electric water heaters can take longer to heat water than gas water heaters.

Limited hot water capacity: Electric water heaters may not be able to supply hot water to multiple appliances simultaneously, making them less suitable for households with high hot water demand.
High operating costs: Electricity is generally more expensive than natural gas, so electric water heaters can be more expensive to operate.
Shorter lifespan: Electric water heaters typically have a shorter lifespan than gas water heaters, lasting around 10 years.
Not ideal for power outages: Electric water heaters rely on electricity to function, so they may not work during power outages.

Heat pump water heaters:

Heat pump water heaters are a newer type of water heater that use electricity to move heat from the air or ground to heat water. Here are the pros and cons:

Pros:

Energy-efficient: Heat pump water heaters can be up to three times more energy-efficient than traditional electric water heaters.
Environmentally friendly: Heat pump water heaters produce fewer greenhouse gas emissions than traditional electric water heaters.
Can provide both heating and cooling: Some heat pump water heaters can also provide heating and cooling for your home, making them a versatile choice.
Low maintenance: Heat pump water heaters require little maintenance, as they have few moving parts.
Long lifespan: Heat pump water heaters can last up to 15 years, which is longer than some traditional electric water heaters.

Cons
:

Higher upfront costs: Heat pump water heaters can be more expensive to install than traditional electric water heaters.
Climate-dependent: Heat pump water heaters can be less efficient in colder climates, as they need to work harder to extract heat from the air or ground.
May require additional installation steps: Heat pump water heaters may require additional installation steps, such as ductwork or a larger breaker box.
Limited hot water capacity: Heat pump water heaters may not be able to supply hot water to multiple appliances simultaneously.
May generate noise: Heat pump water heaters can be noisy during operation.

Solar water heaters:
Solar water heaters use energy from the sun to heat water, making them a renewable energy option. Here are the pros and cons:

Pros:

Renewable energy source: Solar water heaters use energy from the sun, making them a renewable energy option.
Environmentally friendly: Solar water heaters produce no greenhouse gas emissions.
Low operating costs: Once installed, solar water heaters have very low operating costs.
Long lifespan: Solar water heaters can last up to 20 years or more.
May be eligible for tax credits or incentives: In some areas, homeowners may be eligible for tax credits or incentives for installing solar water heaters.

Cons:

Higher upfront costs: Solar water heaters can be more expensive to install than traditional water heaters.
Climate-dependent: Solar water heaters may not be as efficient in areas with less sun or in colder climates.
May require additional installation steps: Solar water heaters may require additional installation steps, such as a larger water storage tank or backup heating source.
Limited hot water capacity: Solar water heaters may not be able to supply hot water to multiple appliances simultaneously.
Requires adequate sun exposure: Solar water heaters require adequate sun exposure to function properly, so they may not be suitable for all homes.

​In conclusion, there are many factors to consider when choosing a water heater, such as energy efficiency, upfront costs, and hot water capacity. We hope this guide has helped you make an informed decision on which type of water heater is right for you and you
