Common questions
What is the downside to tankless water heaters?
The initial investment for a Rinnai tankless water heater is typically higher than that of a traditional tank model. Furthermore, older homes in Ohio may require upgrades to the existing gas line to adequately support the unit's higher BTU input. Ensuring sufficient water pressure is also critical for optimal performance.
Can you run two showers with a tankless water heater?
Yes, a Rinnai tankless water heater, when appropriately sized, can supply hot water to multiple fixtures simultaneously, such as two showers in Dayton. The unit's Gallons Per Minute (GPM) rating is the primary determinant, and our technicians perform precise calculations based on your home's specific fixture flow rates and usage patterns.
How long do hot water heaters typically last?
Traditional tank water heaters generally have a lifespan of 8 to 12 years. Rinnai tankless water heaters, conversely, are engineered for extended durability and can provide efficient service for over 20 years with regular maintenance. Routine flushing to remove mineral deposits is crucial for maintaining peak operational efficiency in Ohio's water conditions.
What is the average cost of putting in a water heater?
The overall cost for installing a Rinnai tankless water heater is influenced by factors such as the specific model's capacity, the complexity of the existing plumbing and venting systems, and any necessary modifications to gas lines or electrical hookups. We provide a transparent, itemized estimate following a thorough on-site assessment.
What is the most efficient type of water heater?
Condensing Rinnai tankless water heaters are recognized as the most energy-efficient option available, utilizing a secondary heat exchanger to recover heat from exhaust gases. This technology significantly reduces energy consumption, surpassing the efficiency of non-condensing tankless units and conventional storage tank water heaters.
Can you run two showers with a tankless water heater?
Indeed, a correctly specified Rinnai tankless water heater can effectively manage the concurrent hot water demands of multiple fixtures, such as two showers. Our technical team meticulously calculates the required Gallons Per Minute (GPM) based on your household's peak usage patterns to ensure uninterrupted service.
