How to Choose the Right Water Heater Size
Having an efficient water heater in your home is crucial for your everyday chores, but you need the right size to ensure the best, long-term results. As your trusted plumber in Lake Elsinore, CA, A.M. Plumbing & Rooter can provide you with professional insights and help you size your unit. Here’s how to go about the process.
Determine the Peak Hour Demand
Sizing your traditional or tankless water heater based on your home’s size is a common misconception. You might live in a huge home, but your water consumption might be low. For this reason, base on your peak water usage instead.
You can determine this by assessing the hot water heater usage during the busiest hour when several family members go about their routine. For instance, if everyone in your home showers in the morning, you may consider this as your peak hour. This will give you an idea of the right capacity for your unit.
Estimate Based on Household Size
If you’re getting a tank-type unit for your water heater installation, you may estimate the proper capacity in gallons based on the number of people in your household. You can use the following guide below:
- 1 to 2 people: 30-40 gallons
- 2 to 3 people: 40-50 gallons
- 3 to 4 people: 50-60 gallons
- 5+ people: 60-80 gallons
This is just a loose estimate, and the ideal tank size will still depend on your hot water usage. A tank that’s too small may not produce enough hot water or cause the unit to overwork, resulting in frequent water heater repair in Lake Elsinore, CA, or premature replacement. Meanwhile, a tank that’s too big might cause your energy costs to skyrocket by heating water you don’t even use.
Consider Flow Rate and Temperature Rise
If you’re going for tankless water heaters, note that they have no storage and heat the water as it flows out for usage. That said, the correct size will depend on the flow rate and temperature rise. The flow rate refers to the gallons per minute (GPM) of supplied hot water, while the temperature rise is the difference between the desired water temperature and the temperature of in-flowing water. Calculating these two can be complicated, so it’s best to seek professional water heater services.

This afternoon we found a leak after disconnecting our refrigerator. We called A.M. Plumbing. Their response time was excellent. They arrived to our house within an hour after calling them. When the plumber got to the house, he was able to rapidly diagnose and fix the problem. He was very professional, did a great job and they charged us a very reasonable fee. I would recommend A.M. Plumbing to anyone that needs plumbing repairs. Thank you, again, for a job well done!
I have called A.M. plumbing twice. Both times the service was excellent. He was able to talk to me about the problem and offer his recommendations. I found him to be trustworthy and reliable, which is what I am looking for in a plumber. I would highly recommend A.M.Dan Steele
Alex and his team are by far the easiest to work with! From the time I spoke with Kristen(sp?) to the time the job was complete they spoke to me like a person and not like I'm an idiot. I had a whole house repipe and an awesome never run out of hot water tankless water heater installed. They were professional and cleaned up after themselves. So glad to have found them on here and will be sure to pass along my experience with them to others. Thank you Alex and the team at AM, our family of 5 can finally have hot showers again!!
