Quick summary
The right water heater size depends on your household’s hot water demand, which factors in the number of people in your house, usage patterns, and the type of water heater (tank or tankless) you’re interested in.
Determining your household’s hot water demand
The first step in selecting your water heater size is determining your household’s hot water consumption. Peak hour demand, often morning or evening hours when most members are home and utilizing hot water, is essential to consider. This covers activities like showering, washing dishes, running the washing machine, and possibly more all at once.
For instance, a family of four people using two bathrooms concurrent might require a water heater with a larger capacity than a two-person home with a single bathroom. Aside from the household size, take into account appliances that require hot water, such as dishwashers and washing machines. Multiple appliances running simultaneously will raise the hot water demand.
Gas vs electric water heaters: Size differences
Gas and electric water heaters operate on different mechanisms, influencing their respective sizes. A gas water heater usually heats up quicker than an electric model, meaning you may be able to get by with a smaller gas heater in comparison to an electric one for the same household. Nonetheless, this decision hangs significantly on personal preferences and existing setup. If you’ve ever asked why your gas water heater is not working, this could be an opportunity to switch to electric, or vice versa.
Another differentiating aspect is tank versus tankless water heaters. While most traditional tank-style water heaters have capacities ranging from 20 to 80 gallons, tankless water heaters don’t store hot water. Instead, they heat the water as needed, making them more energy-efficient. Sizing a tankless water heater requires considering the flow rate and temperature rise you need (measured in gallons per minute – GPM).

- For 1-2 people: Consider a tank with a capacity of 30-40 gallons
- For 2-3 people: Consider a tank with a capacity of 40-50 gallons
- For 3-4 people: Consider a tank with a capacity of 50-60 gallons
- For 5 or more people: Consider a tank with a capacity of 60-80 gallons

The flow rate varies depending on the heated water’s intended use. For example:
- A bathroom faucet would require a flow rate of 0.5-1.5 GPM
- A kitchen faucet might require 1-2.5 GPM
- A dishwasher demands 1-2.5 GPM
- A washing machine needs 1.5-3 GPM
- A single shower requires a flow rate of 1-3.5 GPM
Keep in mind that the total flow rate is the cumulative total of all devices you plan to use simultaneously. Once you know your total flow rate, you can decide on water heater installation.
Conclusion
Choosing the appropriate size for your water heater ensures the perfect balance between energy efficiency and comfort in your home. Undeniably, the process involves a fair amount of calculation and understanding your needs but it’s worth it, in the end, assuring you a consistent supply of hot water exactly when you need it.
