How Do Wall Mounted Hot Water Heaters Work?
Wall mounted hot water heaters are a popular choice for homeowners looking to efficiently heat water for everyday use. These compact units are designed to be mounted on the wall, saving valuable floor space in your home. But how exactly do they work?
On-Demand Heating
One of the key features of wall mounted hot water heaters is their ability to provide on-demand heating. Unlike traditional storage tank water heaters, which constantly heat and store a large amount of water, wall mounted heaters heat water only when you need it.
This is achieved through a heat exchanger, which quickly heats the water as it flows through the unit. This means you’ll have hot water whenever you need it, without having to wait for a storage tank to refill and reheat.
Endless Hot Water
Another advantage of wall mounted hot water heaters is their ability to provide endless hot water. Since these units heat water as it flows through, there is no limit to the amount of hot water they can provide.
This is especially beneficial for households with multiple bathrooms or for those who often use hot water for extended periods of time. With a wall mounted hot water heater, you’ll never have to worry about running out of hot water during a long shower or while doing laundry.
Energy Efficiency
Wall mounted hot water heaters are known for their energy efficiency. By heating water only when it’s needed, these units eliminate the standby heat loss that occurs with traditional storage tank heaters. This means they use less energy and can help you save on your utility bills.
Additionally, many wall mounted hot water heaters are equipped with advanced features such as programmable timers and energy-saving modes, further enhancing their efficiency.
According to the U.S. Department of Energy, tankless water heaters, including wall mounted models, can be up to 24-34% more energy efficient than traditional storage tank water heaters. This can translate into significant savings over time.
Wall mounted hot water heaters not only provide on-demand hot water, but they also offer energy efficiency and endless hot water supply. With their compact design and efficient operation, these units are a great choice for homeowners looking to upgrade their water heating system.
Types of Wall Mounted Hot Water Heaters
Electric
Electric wall mounted hot water heaters are a popular choice for many homeowners. They are easy to install and require minimal maintenance. These heaters work by using an electric heating element to heat the water. The heated water is then stored in a tank and ready for use whenever needed.
One of the advantages of electric wall mounted hot water heaters is that they can be installed in any room, as long as there is access to electricity. They are also energy efficient, as they only heat the amount of water that is needed.
Gas
Gas wall mounted hot water heaters are another common option available to homeowners. These heaters use either natural gas or propane as a fuel source to heat the water. Gas heaters have a higher flow rate compared to electric heaters, meaning they can provide hot water at a faster rate.
They are also more cost-effective in areas where natural gas is readily available and affordable. However, gas wall mounted hot water heaters do require a venting system to remove the exhaust gases, so proper installation is crucial to ensure safety.
Hybrid
Hybrid wall mounted hot water heaters combine the benefits of both electric and gas heaters. These innovative systems use a heat pump to extract heat from the air, which is then used to heat the water.
This makes them highly energy efficient, as they consume less electricity compared to traditional electric heaters. Hybrid heaters are also equipped with a backup heating element, which can be powered by either gas or electricity, providing hot water even in extreme weather conditions or power outages.
Although hybrid heaters are more expensive upfront, their long-term energy savings can offset the initial cost.
When choosing a wall mounted hot water heater, it is important to consider factors such as energy efficiency, installation requirements, and availability of fuel sources. Consulting with a professional plumber is always recommended to ensure you select the right type and size of heater for your specific needs.
What Size Wall Mounted Hot Water Heater Do I Need?
Choosing the right size wall mounted hot water heater is essential to ensure that you have an adequate supply of hot water for your needs. Here are some factors to consider when determining the size of the heater you need:
Calculating Your Hot Water Needs
The first step in determining the size of your wall mounted hot water heater is to calculate your hot water needs. This can be done by considering the number of people in your household, the number of bathrooms, and your daily hot water usage.
To estimate your hot water usage, consider the following:
- The average shower uses about 10 gallons (38 liters) of hot water
- A standard dishwasher cycle uses about 6 gallons (23 liters)
- A load of laundry uses about 20 gallons (76 liters)
Add up the estimated hot water usage for all your daily activities to get a rough idea of the amount of hot water you need.
Match Heater Size to Demand
Once you have calculated your hot water needs, it’s time to match the heater size to your demand. Hot water heaters are typically measured in terms of their capacity to deliver hot water in gallons per minute (GPM).
A good rule of thumb is to choose a heater that can meet your peak hot water demand. For example, if you have a family of four and everyone wants to take a shower at the same time, you would need a heater that can deliver enough hot water for four simultaneous showers.
It’s important to note that a larger heater doesn’t always mean better performance. If you choose a heater that is too big for your needs, you may end up wasting energy and paying higher utility bills.
Consulting with a professional plumber or using online sizing calculators can help you determine the right size wall mounted hot water heater for your specific needs.
