FAQ
Reader questions
How do I know if my home needs a gas or electric tankless unit in Raleigh?
Check your current fuel supply and local costs; if you already have natural gas service and high hot water demand, a gas unit often works best. If you lack gas or need a small, low cost solution, an electric model may suit a Raleigh NC new tankless water heater purchase install better.
What is a good flow rate for simultaneous showers in my house?
For two showers plus occasional dishwasher use, aim for a unit rated around 5 to 7 GPM minimum at the required temperature rise, or consider installing multiple units to balance demand in busy schedules.
Will hard water in Raleigh affect performance and maintenance?
Yes, scale buildup from hard water can reduce efficiency and trigger error codes, so annual flushing and possibly a water softener are recommended parts of routine care for any Raleigh NC new tankless water heater purchase install.
What permits and inspections are required in the Raleigh area?
Most installations require a plumbing permit and possibly an electrical permit, plus a final inspection. Hiring a licensed installer familiar with Raleigh codes helps ensure your tankless water heater meets safety and warranty conditions.
