What’s different about water heater replacement in Denver
High-altitude models
Choose heaters rated for elevation and follow manufacturer altitude derating.
Tankless sizing
Cold incoming winter water and altitude both affect tankless capacity.
Basement venting
Gas heaters in basements depend on proper draft. Replacement should include checking the vent connector and chimney or vent path for the new unit.
Homeowner checklist
- Confirm the new heater is rated for altitude
- Check vent sizing and draft
- Add an expansion tank if the system is closed
- Ask about the permit
