Whole Home Tankless Water Heaters

Whole-home tankless water heaters deliver endless hot water with compact, energy-smart designs. Shop natural gas/propane and high-output electric models, in indoor or outdoor versions, with options for built-in recirculation, Wi-Fi/app control, and clean concentric or twin-pipe venting. Finish installs with vent kits, isolation/flush valves, filters, and maintenance parts.

Shop by need

• Fuel & power: Natural Gas (NG), Propane (LP), or 240V electric
• Location: Indoor (vented) or Outdoor (climate/permitted)
• Type: Condensing (highest efficiency) or Non-condensing
• Recirculation: built-in pump models, recirc-ready units, or add-on kits
• Venting: concentric or 2-pipe (PVC/CPVC/PP as specified) with terminations and pipe covers
• Kits & parts: isolation/flush valves, condensate neutralizers, controllers/Wi-Fi modules, filters, and service parts

Quick choosing guide

1. Size by demand: total your peak fixtures and calculate required GPM at your winter temperature rise. Whole-home gas units typically cover multi-bath demand; electric whole-home requires adequate amperage and is climate-dependent.
2. Pick fuel & service: verify gas meter/line capacity and regulator for NG/LP models, or panel amperage/breaker space for electric.
3. Choose location: Indoor where you can vent; Outdoor where climate/clearances allow and venting is impractical.
4. Efficiency & condensate: condensing units save energy—plan a drain and consider a condensate neutralizer.
5. Faster hot water: select a built-in recirc model or add a recirc kit/crossover; set schedules to cut wait time.
6. Complete the kit: vent kit/terminations, isolation/flush valves, controller or Wi-Fi, and inlet water filtration/scale control as needed.
7. Maintenance: flush/descale periodically (more often with hard water) to protect the heat exchanger.
