Tankless Water Heater Buyer’s Guide
Tankless water heaters are also known as on-demand water heaters. The tankless water heaters have become very popular and for a good reason. When you compare tankless water heaters to the traditional tank water heaters, you will realize that they have many benefits over the traditional unit. Here we will take you through what you have to know to make an informed buying decision.
What is a tankless water heater?
Tankless units have become increasingly popular due to their energy competence and compact design. Tankless units are more energy efficient since they heat water only when it is required. The traditional hot water heaters store the hot water in a storage tank and use energy to keep the water warm while waiting to be used.
Let’s put it this way, when you have a tankless water heater, your hot bath is not restricted by the tank size of your water heater. Energy is only used to warm water, not to store and keep water warm meaning that the hot water is provided on-demand, and not sitting in a tank like the traditional water heaters.
How do tankless water heaters work?
Electric and gas tankless water heaters operate in the same way as the traditional water heaters. The only difference is that they can warm the water much more swiftly and can run only when necessary. This means you do not require a storage tank and don’t consume up the energy required during the standby operation.
When the hot water tap is opened, cold water runs into the tankless system. The system senses the water flow and activated the gas burner or the electrical heating element. This, in turn, heats the heat exchanger. The heat exchanger is that part that warms the water. The heat exchanger is enclosed by the incoming cold water which is then heated to the temperature you desire, and ready to be used.
Tankless water heaters are capable of delivering constant hot water supply. However, they are limited by the flow rate of the unit. The flow rate is the amount of water the tankless system is capable of heating at any particular time. The flow rate of a tankless unit is usually measured in gallons per minute based on a particular temperature increase.
If your system has too small of a water flow rate, it will not be able to deliver sufficient hot water the needs of your household. Choosing a large enough system is an informed decision to avoid running out of hot water.
What are the advantages and disadvantages of tankless water heaters
More energy efficient
Efficiency is the measure of heat transfer from the power source to your hot water. Tankless units tend to run at more than 80 percent efficiency compared to the traditional units operating at 67 percent. Tankless water heaters use less energy since they do not have to keep the water at a constant temperature than the conventional units. They work on an on-demand basis. This means that they use just the exact amount of power to the volume of water that is required. The water is not continuously heated and reheated within the storage tank.
Tankless water heaters stand out due to their effectiveness, both regarding design and cost. They are cost effective because they use on-demand technology which enables the system to operate only when a hot water valve is opened. When you turn off the valve, the unit shuts off by itself. Estimated savings shows that you can cut your utility bill in half every single month by switching to tankless water heaters.
The footprint of tankless water heaters is much smaller, freeing up extra space in your household or garage. Tankless water heaters save space since they mounted on the wall and did not utilize a large water storage tank compared to the traditional unit that has a large reservoir. Since tankless units do not occupy much space, they can fit under your sink, closet, in crawl space or any other small area in your household where there is a space.
Endless hot water
Since the tankless water heaters heat water when needed, it is impossible to run out of hot water. As long as you have a water heater that has water flow rate significant enough to keep up with the demands, then you will run out of hot water.
Longer lasting product
Tankless systems have a longer service life than the traditional water heaters. Tankless water heaters can last 20 years or more with proper maintenance compared to the conventional units which usually last 8 to 12 years. Tankless water heaters are built with high-quality components and materials and are less susceptible to leaks and rust.
Initial cost - Expect to spend much more money when buying a tankless water heater. They may require some additional work upon installation if you decide to upgrade the existing electrical or gas infrastructure.
Expensive venting – gas powered tankless water heaters need expensive venting material.
Output limitations – they are not a good fit for large homes. If the hot water demands of the households are higher than the unit’s capability, then the system will not be able to provide hot water.
Things to look for when purchasing a tankless water heater
Producers size their water heaters by determining the temperature increase to attain an accurate flow rate. The size you select to go with is dependent on how much you need to warm your water. Find out what the average temperature in your area is and check the temperature of your water yourself. Make sure that you have a size which will heat your water enough to make sure that you do not lose gallons per minute (GPM).
Make sure that you do not lose hot water when the demand for hot water is high. Calculate how much GPM you require your ideal tankless water to produce.
Gas or Electric
