Cons:

1. Initial Cost: Tankless water heaters, in general, tend to have higher upfront costs than their tanked counterparts. The Rinnai CHS398100Hcxv is no exception.

2. Potential for Higher Operating Costs: Although the water heater has a high energy efficiency rating, there may be additional costs associated with natural gas usage, depending on the local gas prices.
