Exploring Rinnai V series of tankless water heaters for indoor and outdoor installation and selection of the best models to buy. A review of the main features, technical data with the comparison table of V94, V75, V65 and V53 for the comfortable buying experience.
Rinnai V series water heaters are available in four sizes; V53, V65, V75 and V94.
Rinnai V53e model is the cheapest of all Rinnai, and is available only as the outdoor unit as opposed to other models from V series. It doesn't have the temperature controller MC-91-2US - it is optional, only the status monitor. This is also the smallest and least powerful unit, with the 120,000 Btu of power, able to modulate to 19,000 Btu for smaller jobs. With the flow rate of 5.3 GPM it is used for small homes, cottages and apartments.
Rinnai V94 comes in three models V94i and V94Xi as an indoor and V94e as an outdoor water heater, having the water flow of maximum 9.5 GPM, power of 199,000 Btu and 192,000 Btu for V94Xi model.
Rinnai water heaters from the V series are non-condensing, economy models that are designed in four sizes for residential potable water heating only, reaching the efficiency of 0.82, which is still higher than most of the tank-type gas water heaters.
Even built as economy models and for budget-oriented families, these water heaters can still generate up to 199,000 Btu as the best condensing models, RUR, RUC and RU models, but have the lower energy factor; 0.82 vs. 0.95. These are ideal for homeowners looking to replace an old tank-type water heater, as the retrofit or installing one in the brand new home.
Rinnai V series, from the smallest V53 to the largest V94 are capable of providing endless hot water with the maximum temperature of 140F in a single and multiple applications. The temperature can be set and controlled by using the MC-91-2US temperature controller, where the error codes are displayed if there is a problem with the unit.
For the added convenience, these models are also Wi-Fi capable so the units can be remotely controller and monitored.
Due to the small size of 14" x 23" x 9" for most models, water heaters are easy to handle and mount on the wall, utilizing direct concentric venting system and closed combustion, when installed inside the house.
Indoor water heaters are designed with the closed combustion, using the outside air for gas combustion, while safely moving the products of combustion out, making them suitable for closet, attic and crawl space installations.
The outdoor models are ventless - using the build-in power blower and provided slots for the exhaust.
All Rinnai water heaters from V series are made for water heating on demand while continuously supplying hot water to the residential and mobile homes only, by using the natural and propane gas, except the V94Xi which uses natural gas only.
Thanks to the eco-gas burner and ultra-low NOx gas combustion found on most models, users can enjoy less pollution.
