What’s a Tankless Water Heater?

August 10, 2023

If your current water heater is old, start thinking about replacement before it wears out completely. One of the recommended options is a tankless water heater. Here is what you need to know about tankless water heaters.


How Do Tankless Water Heaters Work? 


The mechanism of tankless water relies on the rapid heating of water flowing through the unit. When you turn on a hot tap, cold water flows into the heater via an inlet pipe. The heating system, often powered by electricity or gas, activates immediately, raising the water's temperature to the desired level. The heated water flows from the unit via an outlet line and travels directly to the appliance or faucet. 


As there is no need for a storage tank, the heating process is instantaneous, saving energy and space. The heater remains dormant when no hot water is required, reducing standby energy consumption. This on-demand system ensures a continuous hot water supply, making it an efficient and practical solution for households and businesses.


What Are the Benefits of a Tankless Water Heater? 


Tankless water heaters have many benefits.


Energy Efficiency


Unlike conventional tank water heaters that maintain a constant hot water supply, tankless units only heat water when needed. This approach significantly reduces standby heat losses and substantially saves energy over time. By eliminating the need to keep a large volume of water hot 24/7, homeowners can lower their utility bills and adopt a more environmentally friendly water heating solution.


Endless Hot Water Supply


Because they heat water on demand, there's no risk of running out of hot water during peak usage times or extended showers. This reliability ensures a continuous and uninterrupted hot water supply, meeting the needs of even the busiest households or commercial establishments. Whether it's a large family or a business with several simultaneous warm water demands, tankless water heaters deliver consistent performance.


Extended Durability


Tankless water heaters offer an extended lifespan compared to traditional tank models. The absence of a standing water supply reduces the risk of rust and corrosion, which can plague conventional tanks over time. Properly maintained tankless units can last up to twice as long as their tank counterparts, making them a durable and cost-effective investment in the long run.


Space-Saving Design


Traditional tank water heaters demand considerable floor space for installation, which can be problematic, especially in smaller homes or commercial buildings with limited real estate. Tankless units, on the other hand, are wall-mounted and occupy minimal space, freeing up valuable floor area for other uses.


Water Conservation


Tankless water heaters contribute to water conservation efforts. With instantaneous heating capabilities, there's no need to let the water run while waiting for it to reach the desired temperature, as often occurs with conventional tanks. This reduction in water wastage not only benefits the environment by preserving water resources but also leads to cost savings on water bills for users.


Versatility


Tankless water heaters offer versatility in both installation and usage. They can be installed in various locations, such as bathrooms, kitchens, or even outdoor areas like poolside showers. Moreover, these units come with adjustable temperature settings, allowing users to tailor the water temperature to their preferences, enhancing comfort and customization.


How Do You Choose a Tankless Water Heater? 


Start by calculating the maximum hot water usage in your household during peak hours. Consider the number of bathrooms, appliances, and simultaneous hot water needs.


Based on your water demand, select a tankless heater with an appropriate flow rate (measured in gallons per minute, GPM) to meet your needs adequately. Look for tankless models with high Energy Factor (EF) ratings. Higher EF values indicate better energy efficiency, leading to reduced utility bills.
