Rinnai Tankless Reviews
This Rinnai tankless water heater has mostly great reviews. Customers of the Rinnai tankless unit love that they have a household that never runs out of hot water anymore. Users report that there is a noticeable difference in energy savings.
Several users mentioned that Rinnai offers a better ‘minimum flow rate’ than most other brands. While most individuals only consider a high ‘maximum flow rate’, when purchasing a tankless water heater, ensuring a lower minimum rate for a tankless heater is also extremely important for a great ‘heated water’ end result.
One customer mentioned that, on school days, there are three showers running at the same time and that his family has never had any issues of not having heated water.
The most consistent statement made by users of this product was that the temperature stayed the same throughout an entire shower, however long that shower was. With regular hot water heaters, adjustment of the knobs is necessary to ensure the same heat through the whole shower. There is no need to adjust with the Rinnai tankless unit.
Overall, the Rinnai R94LSi seems to be a consistently good buy for the money. Installation costs can get high for those hiring professional help, as with any similar unit. Above all, research and go by what the household needs over anything else to ensure years of satisfaction.
