I underestimated the complexity of this aspect; it was more involved than simply connecting the unit to the power supply.
Next, the venting system presented its own set of challenges. My old water heater had a simple vent pipe, but the tankless unit needed a more robust system to handle the exhaust gases efficiently and safely. I had to run a new vent pipe through the exterior wall, which involved drilling a hole and ensuring proper sealing to prevent drafts and gas leaks. This required careful planning and execution to meet building codes and ensure safety. It wasn’t as simple as I initially thought; the process involved precise measurements and careful consideration of the pipe routing to minimize disruption.
Finally, plumbing connections proved trickier than expected. The new unit had different connection points and required adjustments to the existing plumbing. This part of the installation took longer than I anticipated, necessitating careful attention to detail to avoid leaks. Fortunately, Bob, my plumber, was patient and resourceful. He expertly navigated these challenges, making necessary adjustments and ensuring everything was properly secured and leak-free. The entire process was a learning experience, highlighting the importance of professional installation for a high-wattage tankless water heater. The initial challenges were significant, but the end result – endless hot water – was well worth the effort and expense.
My First Hot Shower (and the Wattage’s Role)
After the installation was complete, and the electrician and plumber had signed off, I eagerly anticipated my first shower with the new tankless water heater. The anticipation was palpable! I flipped the switch, and the unit sprang to life with a quiet hum. The moment of truth arrived as I turned on the shower. The immediate impact was noticeable – a powerful, consistent stream of hot water, unlike anything I’d experienced before. With my old tank heater, I often had to endure a period of lukewarm water before the truly hot water arrived. This was especially frustrating during colder months.
The 19.2 kW wattage of my new unit made all the difference. The higher wattage meant a significantly faster heating process, resulting in an almost instantaneous supply of hot water. There was no waiting, no temperature fluctuation, just a constant, comfortable stream of hot water as long as I needed it. I could adjust the temperature with precision, achieving the perfect balance without any delay. This was a luxurious upgrade from my previous experience, where I constantly juggled the temperature settings trying to find that sweet spot.
My family shared my excitement. No more arguments about who gets the last of the hot water! Multiple showers back-to-back were no longer a problem. The consistent hot water flow was a game-changer, especially during peak usage times, like mornings and evenings. The higher wattage wasn’t just about speed; it also ensured a consistent temperature even with multiple shower heads running simultaneously. The difference was astonishing, and it truly highlighted the importance of selecting the appropriate wattage for a tankless water heater. It’s a small detail with a huge impact on everyday comfort.
Energy Efficiency⁚ A Surprisingly Positive Outcome
Before installing my tankless water heater, I had some concerns about energy consumption. I’d heard stories about high-wattage units leading to inflated electricity bills.
