Frequently Asked Questions
What is a tankless water heater?
A tankless water heater, also known as an on-demand water heater, provides hot water only when needed without the use of a storage tank. This offers energy savings and ensures an endless supply of hot water.
How does a tankless water heater work?
A tankless water heater heats water directly as it passes through the unit’s heat exchanger, avoiding the standby energy losses associated with traditional water heaters. When a hot water tap is turned on, cold water travels through a pipe into the unit, where it is heated by a gas burner or an electric element.
What are the benefits of a tankless water heater?
Benefits of tankless water heaters include energy efficiency, space savings, endless hot water supply, longer lifespan compared to traditional water heaters, and reduced risk of leaks due to the absence of a storage tank.
How long do tankless water heaters last?
With proper maintenance, tankless water heaters can last up to 20 years or more, compared to the average lifespan of 10-15 years for traditional water heaters.
What are common issues with tankless water heaters?
Common issues with tankless water heaters include mineral buildup, insufficient hot water flow, fluctuating water temperatures, ignition failure, and venting problems.
Can a tankless water heater be repaired?
Yes, tankless water heaters can be repaired by experienced plumbers. Common repairs may include descaling to remove mineral buildup, replacing faulty components, and adjusting settings for optimal performance.
When should I consider replacing my tankless water heater?
You may consider replacing your tankless water heater if it is nearing the end of its lifespan, experiencing frequent breakdowns, or if the cost of repairs outweighs the benefits of replacement.
Is professional installation necessary for a tankless water heater?
Professional installation is recommended for tankless water heaters to ensure proper sizing, installation, and compliance with local building codes. This helps avoid potential safety hazards and ensures optimal performance.
What size tankless water heater do I need?
The size of the tankless water heater needed depends on factors such as household hot water demand, number of fixtures, and flow rate requirements. A professional plumber can help determine the appropriate size for your home.
Can I perform maintenance on my tankless water heater myself?
While some maintenance tasks such as flushing can be done by homeowners, it’s generally recommended to hire a professional plumber for comprehensive maintenance to ensure optimal performance and longevity of the unit.
Do tankless water heaters require venting?
Yes, tankless water heaters require proper venting to safely remove exhaust gases. Venting requirements may vary based on the type and location of the unit.
