When you’re building a new home or replacing an old hot water system, it’s essential to choose the right size system for your needs. Here’s a step-by-step guide to help you figure out the perfect size for your home.
Hot water usage is measured in liters per hour (LPH). To find out what your peak hot water demand is, you’ll need to know how many liters of hot water you use in a day and divide that by 24 (the number of hours in a day). For example, let’s say you use 100 liters of hot water daily – that would be 100 LPD (liters per day). Divided by 24 hours, that would be approximately 4.15 LPH. This final sum will help you in choosing a new hot water system.
The size you want totally relies upon your high temp water utilizing propensities. If you consistently utilize at least 3 heated water machines around the same time, you could require a lot bigger tank than the graph above demonstrates. However, in the event that you seldom utilize more than one high temp water machine around the same time, you could require a lot more modest tank.

Next, follow these steps.
1. Determine the number of fixtures in your home that use hot water. A fixture is any device that uses hot water, such as a showerhead, faucet, or dishwasher.
2. Add up the flow rates of each fixture. The flow rate is the number of liters per hour (LPH) each fixture uses. This information should be listed on the product label or in the manufacturer’s documentation.
3. Multiply the total LPH by 4 to find out your peak hot water demand – this will give you a cushion so that you don’t run out of hot water during peak usage times.
4. Choose a water heater with a first-hour rating that meets or exceeds your calculated peak demand LPH. The first-hour rating (FHR) measures how much hot water the heater can deliver in an hour and is listed on the product label or in the manufacturer’s documentation.
Make an informed decision when choosing your next hot water system
Now that you know how to figure out the size of the hot water system you need for your house, you can choose the perfect one for your home – good luck!
Choosing the right hot water system for your home is an important decision that can impact your daily life and budget. Here’s a unique overview to help you figure out what size hot water system you need for your house.
Firstly, consider the size of your household and the hot water usage. Larger households require a bigger hot water system to ensure there’s enough hot water for everyone. A general rule of thumb is allowing at least 50L of water per person per day.
Next, determine the peak hot water usage in your home. This is the maximum amount of hot water used at one time, such as when everyone is showering or running the dishwasher. Make sure the hot water system you choose can meet this demand.
Your area’s climate also plays a role in choosing the right hot water system size. In colder climates, larger systems may be needed to compensate for heat loss from pipes and the tank.
Consider the type of hot water system as well. Tankless systems can provide an unlimited supply of hot water, but their flow rate may not be sufficient for larger households. Storage tank systems come in different sizes, so choose one that matches your usage needs.
Lastly, consult a licensed plumber or hot water system specialist for professional advice. They can help you determine your home’s appropriate hot water system size based on your specific needs and circumstances.
By considering these factors, you can confidently choose the right size hot water system for your home and enjoy the benefits of reliable and efficient hot water supply.
