Quality Tankless Water Heater Installation for Homes in Georgetown, DE
GNV Plumbing knows that hard water is the biggest threat to tankless units, since scale builds up inside the heat exchanger. Near the coast around Georgetown, some shallow wells pick up a salty taste, which can wear on pipes and water heaters faster. We install service valves for easy flushing and recommend a scale inhibitor or softener to protect your warranty. You get efficient, endless hot water that keeps working.
Our expertise includes:
- Careful sizing and venting for optimal performance.
- Gas line upsizing and meter capacity checks for high-BTU units
- Condensing and non-condensing gas tankless units with PVC or stainless vent pipe
