Residential water heater capacity varies from 40 to 100-gallons. Since every family has different hot water needs, it is important to choose the right size for your home.
If you choose the wrong tank size, you may end up getting a water heater that is too small or too large for your house.
If you buy a smaller size water heater, it will run out of hot water fast and if you buy one larger than your need, you will end up paying more energy bills for hot water that you won’t use.
Choosing the right size water heater is often a major dilemma for homeowners. Here are some tips that can help you figure out what size water heater is right for your home.
Understand your Hot Water Needs
Search for the right water heater starts by understanding your hot water needs. This mainly depends on the number of people living in your household and their lifestyle habits. You need to consider shower time, bathtub size, and back-to-back showers. Also, consider other appliances in the household such as washing machine, dishwasher etc. Determining these factors is key to understanding your water usage and choosing the right water heater for installation in San Jose.
Water Heater’s First Hour Rating (FHR)
This rating describes the water heaters’ efficiency. It shows the amount of water the appliance can provide in a single hour. The first hour rating gives an idea what the water heater can handle at a peak hour of usage.
Estimate your Peak Hour Demand
This is the amount of water that is typically used during the busiest hour of the day.
For instance: If 2-3 people take showers back-to-back, while running a washing machine and doing Laundry. In that case, the total hot water consumption would be around 65 gallons. So typically, you should a water heater with an FHR of at least 65 gallons per hour.
Consider the place where the water heater will be installed and the available space. A large storage water heater will require a large space for installation. That’s why storage water heaters are often installed in places away from general living such as basement or closet. For those with limited space, a tankless water heater is a great choice.
Type of Fuel Used by the Water Heater
The type of fuel also affects your selection of water heater. There are mainly three types of fuel: electricity, natural gas, and propane. Gas or propane water heaters are more efficient than electric water heaters. This means that if you want to buy an electric water heater you may need a bigger tank compared to gas or propane.
Cost of water heater
This includes both the upfront cost and the cost of operating and maintaining it. You can also compare the Energy Factor (EF) of different water heaters. It is a measure of the heat produced per unit of fuel. The higher the EF rating, the more energy efficient your water heater will be.
So, these are some of the factors you should consider for choosing a water heater size for your home. Usually, a 40-gallon water heater is ideal for a small household of 2 to 3 people. While a 60-gallon water heater is better suited for a larger household of 4 to 6 people. However, these are just estimates and your exact needs may vary. That’s why you should consult with a professional to get the best possible solution for your budget and requirements.
