How to Select the Right Size Tankless Water Heater
- Determine the maximum number of devices you want to run and their total flow rate. Then, add up their flow rates (gallons per minute).
- Determine required temperature rise.

What is the downside of a tankless water heater?
The primary disadvantage of on demand or instant hot water heaters is the upfront cost. The smaller units that you often see won’t produce enough hot water to serve most households. They’ll only serve one faucet at a time—a problem if you want to shower while the dishwasher is running.
Can you run out of hot water with a tankless water heater?
With a tankless system, there isn’t a supply of hot water that can be depleted. Instead, the water heater heats up water as there is a demand for it. It will keep doing this as long as there is demand – and that means you won’t run out of hot water!
What size tankless water heater do I need for a family of 5?

Can a tankless water heater work for the whole-house?
A whole-house tankless water heater is built to provide continuous hot water whenever you need it. Both tank and tankless whole-house water heaters have their advantages. Tank-type water heaters have a lower upfront cost and are often easier to install when replacing a similar type tank water heater.
Is it worth switching to a tankless water heater?
The big advantage of tankless water heaters is that they use less energy since they only heat up water when you need it. You can save hundreds on your energy bill each year. Because they don’t waste power, you can also enjoy the fact that your home will be more sustainable and eco-friendly.
How long does a tankless water heater last?

How big of a water heater do I need for a family of 4?
For 1 to 2 people: 30-40 gallons. For 2 to 3 people: 40-50 gallons. For 3 to 4 people: 50-60 gallons. For 5+ people: 60-80 gallons.
Can I install tankless water heater myself?
Installation. While it is possible to install your own tankless water heater, it’s not a job for inexperienced do-it-yourselfers.
