Tankless Water Heater Installation in East Brunswick, NJ

Frequently Asked Questions

How Long Does Tankless Water Heater Installation Take?

The installation time for a tankless water heater generally depends on whether you are replacing an existing tank-style unit or installing one for the first time. A straightforward replacement can often be completed in a single day, typically taking between four and ten hours. However, if the installation requires running new gas lines, adding dedicated electrical circuits, or modifying venting systems, the process can take longer. More complex installations, especially those requiring significant plumbing or structural changes, might extend into a second day. Your installer should provide a more accurate time estimate after assessing your specific home and existing setup.

Is Professional Installation Required for a Tankless Unit?

Yes, professional installation is strongly recommended and often required for a tankless water heater. These units involve complex connections to your home's gas, electrical, and water lines, which must all comply with local building codes. Improper installation can lead to inefficient operation, code violations, gas leaks, water damage, or even carbon monoxide hazards. A licensed plumber or HVAC technician has the expertise to correctly size the unit, ensure proper venting, and safely connect all utility lines. Hiring a professional also often ensures your unit's warranty remains valid, as manufacturers typically require certified installation.

What Size Tankless Water Heater Do I Need?

The correct size for a tankless water heater is determined by the maximum flow rate, measured in gallons per minute or GPM, and the required temperature rise. You need to calculate the total GPM demand by estimating the number of hot water fixtures you plan to use simultaneously. Next, you must consider the temperature rise, which is the difference between your desired hot water temperature and your incoming cold water temperature. The unit must be powerful enough to heat that volume of water to the target temperature as it flows through the system. A professional plumber will perform these calculations precisely to recommend a unit that can handle your peak usage without running cold.

How Often Do Tankless Units Need Maintenance?

Tankless water heaters generally require maintenance once a year to ensure optimal performance and longevity. The most critical part of this annual service is flushing the unit to remove any mineral buildup, scale, or sediment from the heat exchanger. Hard water areas may require more frequent flushing to prevent blockages that decrease efficiency and could damage the unit over time. Regular maintenance prevents breakdowns, helps the unit maintain its energy efficiency, and keeps the manufacturer's warranty valid. We offer comprehensive maintenance plans to ensure that your tankless water heater is in top shape year-round.
