Tankless Water Heater for New Construction: What Buyers Should Verify

Verifying Tankless Water Heater Quality in New Homes

New construction does not guarantee quality tankless water heater work. In fact, the rush to complete homes on schedule and within budget often leads to shortcuts in tankless water heater installation that do not become apparent until years after closing. As a buyer, you have a limited window before and after closing to identify and require correction of deficiencies, making it essential to know exactly what to check and how to verify that the work meets professional standards.

The most common tankless water heater issues in new construction include: using lower-grade materials than specified, inadequate preparation of the substrate or foundation, skipping required waterproofing or sealing steps, and failure to follow manufacturer installation specifications that are prerequisites for warranty coverage. Each of these issues can be identified through careful inspection if you know what to look for.
