Tankless Water Heaters — Installation & Replacement

Endless hot water, smaller footprint, higher efficiency. We replace tank units or install new tankless systems with correct gas, venting, and water quality setup so you get reliable hot water at the right flow rate.

Is tankless right for your home?

• You want endless hot water for back-to-back showers
• Limited space for equipment; prefer a wall-mounted unit
• Lower gas use with high-efficiency condensing models
• Willing to do simple annual descaling where water is hard

Sizing done correctly

We size by gallons per minute and temperature rise. A typical home lands in the 7–11 GPM range depending on climate and simultaneous fixtures. We verify shower counts, tub fill rates, laundry, and dishwasher loads so the unit never starves.

What we install

• Gas tankless: standard or condensing for higher efficiency
• Venting: stainless or PVC for condensing, sealed and sloped for condensate
• Gas line upgrades: larger BTU demand often needs upsizing
• Water quality protection: flush valves, isolation kit, and scale control
• Recirculation options: dedicated return line or crossover valve for faster hot water at far fixtures
• Outdoor-rated units where climate and code allow

Installation process

1. On-site assessment — confirm gas capacity, vent path, electrical, water hardness, and fixture demand.
2. Options and written pricing after the visit — standard vs. condensing, recirc choices, water treatment if needed.
3. Permits and scheduling — we handle code and inspection.
4. Professional installation — remove old heater, mount and pipe the new unit, correct gas shutoff and sediment trap, venting and condensate drain, isolation/flush valves.
5. Start-up and tuning — set temperature, verify flow at key fixtures, user walk-through for maintenance.

Maintenance and reliability

• Annual flush/descale in hard-water areas
• Clean inlet screens and check condensate drain
• Recirc systems: set timers or smart controls to reduce energy use
