FAQs about instant water heaters

Q1. What are the benefits of using an instant water heater?

Ans. Instant water heaters offer several benefits, including energy efficiency, space-saving design, and continuous hot water supply. Since they only heat water on demand, they consume less energy compared to traditional tank heaters, which continuously heat stored water.

Q2. How do I choose the right size instant water heater for my home?

Ans. The size of the instant water heater depends on the flow rate and temperature rise required for your household. Determine the flow rate by calculating the gallons per minute (GPM) of all the fixtures you plan to use simultaneously. Choose a unit that can handle this flow rate with an adequate temperature rise to ensure sufficient hot water.

Q3. What maintenance is required for an instant water heater?

Ans. Regular maintenance includes descaling the unit to prevent mineral buildup, especially in areas with hard water. It is also essential to inspect and clean the inlet filter regularly. Annual professional servicing can help ensure optimal performance and extend the heater's lifespan.
