The quick flush feature simplifies maintenance, which is a plus for users who may not have much experience with water heaters. However, the reliance on professional installation could deter DIY enthusiasts or those looking to save on installation costs.

The Rinnai RX199iN is a solid choice for households seeking a reliable and efficient tankless water heater.

On the downside, the product requires professional installation, potentially adding to the initial cost. Another consideration is its non-condensing nature, which might make it slightly less efficient compared to condensing models.
