Tankless vs. Tank Type
As a plumber, one of the most common questions I get from homeowners is whether they should choose a tank type or a tankless water heater. It's a decision that can have a significant impact on energy efficiency, operating costs, and overall comfort in the home. In this blog post, I'll provide some insights into both types of water heaters, their advantages and disadvantages, and how to choose between them.
Tank Type Water Heaters
Tank type water heaters are the traditional type of water heater that most people are familiar with. They have a large tank that stores hot water and keeps it at a consistent temperature until it is needed. Tank type water heaters come in a range of sizes, from small 20-gallon models for apartments or condos, to large 80-gallon models for larger homes.
Advantages:
Lower upfront cost: Tank type water heaters are generally less expensive than tankless models, making them a popular choice for homeowners on a budget.
Simpler installation: Because tank type water heaters are more commonly used, most plumbers are familiar with their installation and maintenance, which makes the installation process easier and faster.
Less sensitive to water quality: Tank type water heaters are generally less sensitive to water quality issues such as hard water or high levels of sediment.
Disadvantages:
Limited hot water supply: Tank type water heaters can run out of hot water if the demand exceeds the tank's capacity. This is especially true for larger families or households with high hot water usage.
Higher energy costs: Tank type water heaters are less energy-efficient than tankless models, as they have to continually heat and maintain a large tank of water, even when it's not in use.
More maintenance required: Because tank type water heaters store water, they can be more susceptible to corrosion and sediment buildup, requiring more frequent maintenance.
Tankless Water Heaters
Tankless water heaters, also known as on-demand water heaters, provide hot water only when it's needed. They heat water directly as it passes through the unit, without the need for a storage tank. Tankless models are available in both electric and gas-powered models.
Advantages:
Energy efficiency: Tankless water heaters are more energy-efficient than tank type models, as they only heat water when it's needed, reducing standby losses.
Unlimited hot water supply: Because tankless water heaters heat water on demand, they can provide an unlimited supply of hot water, making them ideal for larger families or households with high hot water usage.
Longer lifespan: Tankless water heaters typically last longer than tank type models, with an average lifespan of 20 years, compared to 10-15 years for tank type models.
Disadvantages:
Higher upfront cost: Tankless water heaters are generally more expensive than tank type models, which can make them less accessible to homeowners on a budget.
More complex installation: Because tankless water heaters are less commonly used, their installation can be more complex and require specialized knowledge.
Sensitive to water quality: Tankless water heaters can be more sensitive to water quality issues such as hard water or high levels of sediment, which can cause damage to the unit and require more frequent maintenance.
How to Choose
When deciding between a tank type or tankless water heater, there are several factors to consider:
Budget: Tank type water heaters are generally less expensive upfront, while tankless models can provide long-term energy savings but have a higher initial cost.
Hot water demand: If you have a large family or household with high hot water usage, a tankless water heater may be a better choice to ensure an unlimited hot water supply.
Installation: If you're installing a water heater in an existing home, a tank type water heater may be a simpler and less expensive option.
