常见问题FAQ
Is a tankless water heater worth the investment?
Yes — despite higher upfront cost ($3,000-$5,000), it saves $100+/year on energy and lasts 20+ years vs 10-12 for tank.
What size tankless water heater do I need?
Depends on flow rate needs. 2-3 bathroom home needs 8-10 GPM. We calculate the exact size during free consultation.
Can I convert from tank to tankless?
Yes, we handle the full conversion including gas line upgrade, venting, and electrical work if needed.
How often does a tankless water heater need maintenance?
Annual descaling service ($150-$250) is recommended, especially in NYC with hard water.
What brands of tankless do you recommend?
Navien for best overall value, Rinnai for reliability, Noritz for budget-friendly. All come with strong warranties.
