A tankless water heater saves space in tight rowhome basements and delivers endless hot water. Still, older homes need a few upgrades first.
We install tankless units in South Philly, Fishtown and Manayunk, and each job starts with the gas line.
Gas Line and Power Needs
Tankless units burn far more gas while running than a tank.
- Gas line sized for the unit’s full demand.
- A nearby outlet for controls.
- A drip leg at the gas connection.
Venting a Tankless Water Heater
Condensing units vent through PVC instead of the chimney. Therefore, routes are flexible.
- Intake and exhaust through a side or rear wall.
- Clearances from windows and doors.
- A condensate drain with a neutralizer.
The U.S. Department of Energy explains how tankless heaters compare with tanks.
Yearly Maintenance
Hard water builds scale inside the heat exchanger.
- Flush through service valves every year.
- Clean the inlet filter.
- Check the condensate line.
