Here is the rule of thumb for water heater sizing:įirst Hour Rating (Heater Capacity) ≤ Peak Hour Demand (Usually 1 hour when we shower) Just check the label, and you will find out how big your water heater actually is. The FTC (Federal Trade Commission) rule is that every conventional storage water heater producer has to include this rating on the EnergyGuide label.

It is a volumetric amount of hot water a heater can provide within the first hour, starting with a tank full of hot water.
This is also known as ‘first hour rating’. That number of gallons is the ‘water heater capacity rating’. We talk about 30-gallon, 40-gallon, 50-gallon, 60-gallon water heaters. The key spec that helps us adequately size a water heater is the water heater capacity rating. With this knowledge, you will easily understand the prepared table with water heater sizes for a family of 1, 2, 3, 4, 5, and 6: How To Estimate The Size Of A Water Heater You Need? Let’s first familiarize ourselves with water heater sizing concepts like ‘first hour rating’, ‘water heater capacity’, and ‘peak hour hot water demand’. Just input family size and relative hot water needs, and you will get a rough estimate of how big a hot water heater you need. Here’s what the results look like (screenshot): You can find this ‘Water Heater Sizing Calculator’ further on. You just input the size of your family, hot water needs, and the calculator will give you a rough estimate of how big a water heater you need, based on average hot water consumption. On top of that, we simplified water heater sizing with a ‘Water Heater Sizing Calculator’. We include the general rule of thumb for sizing any water heater (it’s fairly easy to use, but you need to estimate your peak hour hot water demand properly). That includes factors that increase/decrease the water heater capacity requirements (size of your family, hot water needs, etc.). That’s we will look into how to pick the right water heater size for your home. You don’t want to blow it and buy a unit that’s either too big or too small. You only have one shot at sizing your water heater. That’s at about 20-gallons more than you need, and you have needlessly spent $150 additional dollars on the heater, and wasted space.īoth of these mistakes can be avoided if you know how to properly choose a water heater capacity for your hot water needs. Example of a too big water heater: Installing a 60-gallon water heater for a family of 2. If the water heater capacity surpasses your hot water needs, you have unnecessarily higher water heater costs.
