Why Choose Alpha Plumbing for Tankless Installation
- Tankless Specialists: This isn’t a side service for us. We specialize in tankless water heaters and understand the nuances that general plumbers often miss—proper sizing, adequate gas supply, correct venting, and optimal placement.
- Brand Expertise: We’re experienced with Rinnai, Rheem, and Navien—the industry’s top brands. We know the pros and cons of each and can help you choose the best fit for your home.
- Proper Sizing: An undersized tankless unit won’t keep up with demand; an oversized one wastes money. We calculate your actual hot water needs to recommend the right size.
- Gas Line Capability: Many tankless installations require gas line upgrades. We handle this in-house, so you’re not coordinating multiple contractors.
- Honest Assessment: Not every home is right for tankless. We’ll tell you honestly if tank or tankless makes more sense for your situation.
Benefits of Tankless Water Heaters
- Endless Hot Water: Unlike tank heaters that can run out, tankless units heat water on demand. Take back-to-back showers, run the dishwasher, and do laundry—all without running cold.
- Energy Savings: Tankless water heaters only heat water when you need it, eliminating the standby energy loss of keeping 40-50 gallons hot 24/7. Most homeowners see 20-30% reduction in water heating costs.
- Space Savings: Tankless units mount on the wall and are about the size of a small suitcase. Free up valuable floor space in your utility room or garage.
- Longer Lifespan: While tank water heaters typically last 10-12 years, tankless units often last 20+ years with proper maintenance.
- Cleaner Water: No tank means no sediment buildup sitting in standing water. Your hot water is fresher.

Frequently Asked Questions About Tankless Water Heaters
How much does tankless water heater installation cost?
Tankless installation typically costs more upfront than tank water heaters due to the unit cost and potential gas line upgrades. However, the energy savings and longer lifespan often make tankless the better long-term investment. We provide exact pricing after assessing your home—no ballpark guesses.
Can my home’s gas line handle a tankless water heater?
Many homes need gas line upgrades for tankless installation. We assess this during our initial visit and include any necessary upgrades in your quote. We handle gas line work in-house.
How long does tankless installation take?
A straightforward replacement typically takes 4-6 hours. If gas line upgrades or significant venting work is needed, it may take a full day. We’ll give you a clear timeline before we start.
Which brand do you recommend: Rinnai, Rheem, or Navien?
All three are excellent brands. Rinnai is known for reliability and service network. Rheem offers great value and performance. Navien excels in efficiency and includes a recirculation pump in many models. We’ll help you choose based on your priorities and budget.
Does a tankless water heater need maintenance?
Yes—especially in East Tennessee where water tends to be hard. Annual descaling keeps your tankless unit efficient and extends its lifespan. We offer maintenance service for all brands.
