7 Questions to Ask About Tankless Water Heaters
Just because it’s tankless doesn’t mean you shouldn’t come armed with questions
Tankless water heaters offer the perfect solution in homes where space is tight and energy efficiency is important. Because you’ll use it every day, choosing the right product and getting it installed correctly is essential. So, before you tackle this project, jot down these questions to ask about tankless water heaters so you can discuss them with your pro.
1. When do you need this work done?
A tankless water heater can take a professional four to ten hours to install. Because this is a time-consuming installation, you should ensure you can dedicate most of the day to it. During the slow season of winter, you might be able to save on installation costs.
2. What is the heat source for the tankless water heater?
Most tankless water heaters use natural gas or electricity as the heat source, but some water heater types use solar energy or propane. Determine what type of heat source you want to use for your tankless water heater before you purchase a unit. You may need a new natural gas line installed or a new electrical outlet for your water heater.
3. How much water do you need heated?
The size of your home and the number of people living in it play a role in determining the size of your tankless water heater. It's crucial that you correctly calculate your tankless water heater size to avoid running out of hot water. The number of fixtures in your home is one way you can calculate the flow rate of your plumbing system. With this information, a professional can help you choose the best tankless water heater size for your home.
4. What kind of tankless water heater do you want installed or repaired?
If you don't already have a tankless water heater installed, choosing one is one of the first steps. The most energy-efficient option is a solar water heater, but they typically cost more than other water heaters. Knowing your budget can help: Tankless water heaters cost between $1,400 and $3,900 on average, but solar water heaters cost between $1,800 and $5,700.
5. Do you have a problem with your current tankless water heater?
Identifying the reason your tankless water heater isn't working can help your technician diagnose the problem before they come to repair it. Some of the most common problems with tankless water heaters include:
Sediment buildup
Too much demand for the size of the water heater
Failure to ignite (gas tankless water heaters)
Blockages in the air ventilation system
Faulty temperature sensor
6. What plumbing do you need help with?
If you live in an older home, then you may need extensive plumbing work to have a tankless water heater installed. Old pipes may need replacing before a pro gives your home the go-ahead. Likewise, smaller homes that don't offer much space may be limited in where one can be installed, which could require additional local plumbing services to reroute the water.
7. Where do you want your water heater installed?
Even if your water heater is tankless, the location of your tankless water heater may make it difficult for a professional plumber or water heater technician to access the unit. Some water heaters are located in a designated area, making them easy to access, while others may be in a basement or garage. Consider clearing any space that could slow down the repair or installation process to save on labor costs.
