Tankless Water Heater FAQs

Considering a tankless water heater? Get answers to frequently asked questions about tankless water heaters and connect with reputable installers in USA.

What are the pros and cons of a tankless water heater?

Advantages:
  • Endless hot water: Provides an unlimited supply on demand.
  • Energy efficiency: Heats water only when needed, reducing energy costs.
  • Space savings: Compact and wall-mounted, saving space compared to tank water heaters.
  • Long lifespan: Lasts up to twice as long as tank water heaters.

Disadvantages:
  • Higher upfront cost: Initial purchase and installation costs are higher.
  • Limited flow rate: May not meet high simultaneous hot water demand.
  • May require upgraded gas lines or electrical circuits: Ensure your home's infrastructure can handle a tankless unit.

How do tankless water heaters work?

Unlike traditional tank water heaters that store hot water, tankless water heaters, also called on-demand water heaters, only heat water when needed:
  1. Cold water enters the unit when you turn on a hot water tap.
  2. A flow sensor detects the water flow and activates the heating element (gas burner or electric coils).
  3. The heating element quickly raises the water temperature to the set point.
  4. Hot water is delivered to the fixture, providing instant and continuous hot water for as long as the tap is on.
This eliminates standby heat loss and ensures hot water availability.

How long does a gas water heater last?

The average lifespan for a gas water heater is 8-12 years. However, regular maintenance, water quality, and usage patterns can affect longevity.

How to maintain a tankless water heater?

Regular maintenance is crucial for a tankless water heater's longevity and performance. This includes:
  • Flushing the unit: Removing mineral deposits and sediment buildup by flushing with a descaling solution.
  • Cleaning air filters (if applicable): Ensuring adequate airflow for combustion.
  • Checking venting: Inspecting the venting system for obstructions or leaks.
  • Annual inspection: A professional inspection can identify and address minor issues before they become major problems.
Following the manufacturer's recommendations is crucial for proper upkeep.
