- An electric element or gas burner heats the water as it passes through a heat exchanger.
- The heated water is then delivered to the faucet or tap, providing instant hot water.
One of the main advantages of tankless instant hot water dispensers is their energy efficiency. Since they only heat water on demand, they don’t waste energy by continuously heating and reheating water in a storage tank. Additionally, tankless dispensers can provide a constant supply of hot water, as they are not limited by the capacity of a storage tank.
However, there are some considerations to keep in mind if you’re considering a tankless system. Firstly, the initial cost of a tankless dispenser can be higher compared to a tank-type dispenser. Additionally, the flow rate may be limited, meaning that the dispenser may not be able to provide hot water at a high rate for multiple tasks simultaneously. Finally, installation for a tankless dispenser may be more complex, as it requires electrical or gas connections and may need ventilation for gas burners.
2. Tank-Type Instant Hot Water Dispensers
Tank-type instant hot water dispensers, also known as storage tank water heaters, store and heat water in a tank, ready to be dispensed when needed. Here’s how they work:
- Water is initially heated and stored in the tank at a specific temperature.
- When you turn on the faucet or tap, hot water from the tank is delivered to the faucet.
- As hot water is used, cold water fills the tank and is heated to maintain the desired temperature.
Tank-type instant hot water dispensers are generally more affordable upfront compared to tankless systems. They also have a higher flow rate, allowing for multiple tasks, such as showering and dishwashing, to be done simultaneously without a decrease in hot water supply.
However, one of the main drawbacks of tank-type dispensers is their energy consumption. Since the water in the tank needs to be continuously heated to maintain a specific temperature, there can be energy loss due to standby heat loss. This means that even if you’re not using hot water, the tank is still using energy to keep the water hot.
Additionally, tank-type dispensers may run out of hot water if the demand exceeds the capacity of the tank. While the tank can be refilled and reheated, there may be a delay in obtaining hot water during periods of high usage.
Conclusion
When comparing tankless and tank-type instant hot water dispensers, it’s important to consider your specific needs and preferences. If energy efficiency and a constant supply of hot water are your priorities, a tankless system may be the better choice. On the other hand, if affordability and a higher flow rate are more important, a tank-type system may be the way to go. Ultimately, both options can provide instant hot water, so it’s a matter of finding the one that best suits your needs.
