Why We Recommend This System
Our installer's perspective:
- For households frustrated by running out of hot water, tankless solves the problem completely.
- Rheem tankless units are among the most reliable on the market with excellent service records.
- The long lifespan means better value despite higher upfront cost. You buy fewer units over time.
- Energy savings are real, especially for households with variable hot water demand.
When it might not be the best fit:
If you have low hot water demand, the energy savings may not justify the higher upfront cost. Tank heaters work fine for smaller households. Not ideal for homes with hard water, as tankless units can scale quickly without proper treatment.
Alternative: For simpler needs, the John Wood Power Vented tank costs less upfront and works well for moderate demand.
