The Tankless Water Heater: Flow Rate And Temperature

Are you looking for a way to save money on your water heating costs? Many consumers who have invested in tankless water heaters have reported substantial savings on their energy costs. Both homeowners and business owners have found these “on demand” water heating systems to be energy efficient and convenient to own. They don’t store hot water, like conventional water heaters. Which means there’s no stand-by energy being used, which lowers your heating costs.

Sizing Your Tankless Water Heater

The size of your tankless water heater should be chosen based on your water heating needs. The first thing you need to decide is where you will need hot water. This will ensure that you purchase the correct application for your needs. The information below gives a small description of three applications:

1. Single Point Application: This application is used for heating water in one-single area. This would be great for businesses that only need to heat water in a sink. For example, a beauty salon.

2. Multi-point Application: This is an application that is great for one room that has multiple points that need water heated. A prime example of this would be an entire kitchen. It’s one room, with a sink and a dishwasher. This application will ensure that water is sufficiently heated in both areas of this single room.

3. Whole House Application: The purpose of this application is to heat the water of an entire household. It efficiently provides hot water for a whole house, apartment, townhouse or condominium. It’s also great for businesses with multiple water points, such as a restaurant.

Flow Rates of Tankless Water Heaters

Understanding the flow rate you will need is another factor for choosing the right option, based on your needs. See Typical Flow Rates in Gallons per Minute (gpm) for more flow rate statistics.

• A 240 Volt power system – water temperature rises up to 125°F.

• Hot Water Rate Provided: 2-5 gallons per minute

• Can use larger system for whole house use, or multiple smaller ones.

Choosing the Right Tankless Water Heater Application

The next thing you will need to decide on is the application that’s best for you. Here are a few examples and their specific application uses:

• Electric Point of Use – Good for use with one fixture

• Flow Controlled – Great for two points of usage that are very near each other

• Thermostatic – Gives you the ability to set it to control exact temperatures

• Whole House Indoor or Outdoor Uses – Used to heat water in an entire house, apartment, condo, townhouse, small office building, etc…

Save Money with On-Demand Water Heating
