Have to replace my 12 year old gas Rheem tankless water heater due to a water jacket leak. Bought it in 2011 from HD along with a 10-year extended protection plan brings support out to 2026. However, there is no service support in my area according to the agents.
Considering replacing with a new water heater with a built-in recirculation pump as it does take a while to get hot water. The challenge is a Manabloc PEX manifold. The manifold is ~50' from the heater. Guess what? Can easily install a bridge valve under the kitchen sink as it's connected to 1/2" copper- prior to the manifold. When I remodeled the house, saw no reason to connect the kitchen to the manifold as it's inches away. Could also add a separate 3/4" copper return line back to the water heater. Or could just lie down until the feeling goes away.
Looked at a Rinnai tankless water heater warranty this morning. Limited 15 years or 12,000 hours. 12,000 hours...hmm. If operating 24 hours a day, that's only 1.37 years. Let's say I use a recirculation pump & set it on a timer for 4 hours a day/7 days a week. Guess what? 15 years just shrunk to just over 10.25 years. There's no free lunches.
