Continuous Flow Water Heaters: Know More About Them
Jul
As an alternative to standard storage tank water heaters, tankless or continuous flow water heaters are becoming increasingly popular. Unlike storage tank systems, tankless heaters heat water as it flows through the unit, so there is a never-ending source of hot water.
Key Benefits of Continuous Flow Water Heaters
Energy Efficiency
Continuous flow heaters only heat water when needed, saving energy when not used, like holding tank systems do. Reducing energy waste can save a lot of money, especially for homes that don't use a lot of hot water.
Endless Hot Water
With a continuous flow system, you'll always have hot water, even during peak usage. The unit heats water as needed, so the supply is essentially limitless.
Compact Size
Continuous flow heaters are much smaller than storage tank models, making them an excellent option for homes with limited space. They can often be wall-mounted, freeing up floor space.
Precise Temperature Control
Many continuous flow heaters offer precise digital temperature controls, allowing you to set the hot water temperature you need.
Reduced Maintenance
Without a storage tank, continuous flow heaters have fewer components that can fail over time. Minimal system failure generally means less maintenance and a longer lifespan than traditional water heaters.
Types of Continuous Flow Water Heaters
Continuous flow water heaters are available in both gas-fired and electric models. Gas-fired units can heat more effectively and provide hot water quickly, but electric models are often smaller and easier to set up. These are the details for these types of water heaters:
Gas-Fired Continuous Flow Water Heaters
Advantages
1. Higher heating capacities, able to provide hot water more efficiently
2. Usually last longer than electric models
3. Homeowners who use a lot of hot water may find that running it costs less.
Considerations
1. Require access to natural gas or LPG supply
2. May have higher upfront installation costs
3. Produce greenhouse gas emissions during operation
Electric Continuous Flow Water Heaters
Advantages
1. More compact and easier to install, often wall-mounted
2. There is no need for a gas supply; you can install it in more locations
3. Don't release any direct climate gases while they are running
Considerations
1. Generally have lower heating capacities compared to gas models
2. May have higher operating costs, especially for households with high hot water usage
3. Require sufficient electrical capacity and wiring in the home
When choosing between gas or electric tankless flow water heaters, key factors to consider include:
1. The available utility connections (gas or electric) in your home
2. The size of your household and hot water usage needs
3. Your budget and ongoing energy costs
4. Sustainability and environmental impact preferences
How to Choose the Best Continuous Flow Water Heater for Your Home
There are a few essential things to think about when choosing a continuous flow (or portable) water heater for your home:
Fuel Type
Tankless water heaters are available in gas-fired and electric models. Gas models usually have more heating power and can heat water more effectively, while electric models are generally smaller and easier to set up. When choosing between gas or electric, consider the available utility connections in your home.
Heating Capacity
Kilowatts (kW) measure a continuous flow water heater's heating ability, which tells you how much hot water the unit can produce. Choose a water heater capacity that matches your household's hot water needs - larger homes with higher demand require a higher capacity unit.
Energy Efficiency
Look for continuous flow water heaters with high energy efficiency ratings. These ratings will help minimise your ongoing energy costs. Many models now offer advanced features like low-emission burners and precise temperature control to boost efficiency.
Size and Placement
Tankless water heaters are much more compact than traditional storage tank models, allowing for flexible placement. Consider where you will install the unit and ensure it will fit the available space. Wall-mounted models are a popular choice.
Brand and Warranty
Research reputable brands like Rinnai, Rheem, Dux, and Bosch that offer continuous flow water heaters designed for the market. Also, look for models with comprehensive warranties for peace of mind.
Carefully evaluating these key factors can help you select the best continuous flow water heater to meet your home's hot water needs. Feel free to get personalised help from a licensed plumber.
