electric water heater that is located in the attic where there is extremely hot and during winter Rinnai RX160iN Condensing Smart Sense Natural Gas or Propane Tankless Water Heater, Indoor or Outdoor Water Heater, Up to 9 GPM, 160,000 BTU 

That's actually a clever hybrid approach! Let's analyze this dual-season strategy:

Summer Benefits (Electric in Attic):

• Attic temperatures can reach 130-150°F

• Significantly reduced heating needs due to:

  • Pre-heated incoming water from hot attic

  • Generally warmer ground water

• Lower operating costs since:

  • Less energy needed to reach target temperature

  • Can potentially avoid propane costs entirely

  • Could use timer to heat during off-peak rates

Winter Benefits (Rinnai RX160iN):

• More efficient in cold weather than electric

• No risk of frozen pipes in attic

• 160,000 BTU provides good cold weather performance

• Condensing technology maximizes efficiency

• Only paying for propane 4-5 months/year

Cost Impact:

1. Summer (Electric):

• Lower operating costs due to attic heat

• Estimated $30-50/month electric

• No propane costs

2. Winter (Propane):

• ~15-20 gallons propane/month

• Only during cold months

• ~$45-60/month in propane
