A tankless water heater, also known as an on-demand water heater, is a popular choice for homeowners who want to save energy and space. Unlike traditional water heaters, which store and heat a large amount of water in a tank, tankless water heaters heat water as it passes through the unit. If you’re considering buying a tankless water heater for your home, there are several things to keep in mind. In this article, we’ll cover everything you need to know about buying a tankless water heater.
- Types of Tankless Water Heaters
There are two main types of tankless water heaters: electric and gas. Electric tankless water heaters are typically less expensive to purchase and install, but they may not be able to keep up with the demand for hot water in larger households. Gas tankless water heaters are more expensive, but they are more energy-efficient and can provide a higher flow rate of hot water.
- Size and Flow Rate
When choosing a tankless water heater, it’s important to consider the size of your household and your hot water needs. Tankless water heaters are rated by their flow rate, which is the amount of hot water they can provide per minute. For example, a small tankless water heater may have a flow rate of 2-3 gallons per minute, while a larger unit may have a flow rate of 7-8 gallons per minute.
- Energy Efficiency
One of the main benefits of a tankless water heater is its energy efficiency. Unlike traditional water heaters, which keep a large amount of water hot at all times, tankless water heaters only heat water as it is needed. This can result in significant energy savings over time. When shopping for a tankless water heater, look for models that are Energy Star certified for maximum efficiency.
- Installation Requirements
Installing a tankless water heater can be more complicated than installing a traditional water heater. Tankless water heaters require a dedicated gas line or electrical circuit, and may also require additional venting. It’s important to have your home’s electrical and gas systems inspected before installing a tankless water heater to ensure they are compatible with the unit.
- Maintenance Requirements
Like any appliance, tankless water heaters require regular maintenance to keep them running smoothly. This may include flushing the unit to remove mineral buildup and replacing filters. It’s important to follow the manufacturer’s maintenance guidelines to ensure the unit stays in good condition.
- Cost
The cost of a tankless water heater can vary depending on the size and type of unit, as well as installation costs. While tankless water heaters may be more expensive upfront than traditional water heaters, they can provide significant energy savings over time. It’s important to consider both the upfront and long-term costs when making your decision.
- Warranty
When buying a tankless water heater, it’s important to consider the warranty. Look for units with a solid warranty that covers both parts and labor. This can provide peace of mind and protect your investment in the unit.
In conclusion, buying a tankless water heater can be a great choice for homeowners who want to save energy and space. When shopping for a unit, consider the type, size, flow rate, energy efficiency, installation requirements, maintenance requirements, cost, and warranty. With the right tankless water heater, you can enjoy hot water on demand and lower energy bills for years to come.
