Rinnai V65iN Value Series Indoor Tankless Water Heater
Rinnai V65iN Value Series Indoor Tankless Water Heater Review
The Rinnai V65iN Value Series Indoor Tankless is Rinnai's mid-sized value tankless, sitting between the V53iN/iLP (smaller) and V94iN/iLP (larger) in the Value Series. "65" reflects 6.5 GPM rated capacity; "iN" means indoor natural gas.
Specs: 150,000 BTU natural gas input, UEF 0.82 (non-condensing), 6.5 GPM at a 35°F rise. Category III stainless steel B-vent venting. Copper heat exchanger. 10-year warranty on heat exchanger.
The 150K BTU class is right-sized for 1-2 bath homes in warm climates or 1-bath homes in cold climates with sequential demand. Smaller gas line requirements than 199K BTU tankless — often 3/4" line works at typical distances.
The Value Series is Rinnai's budget tankless line. About $1,100 unit, $2,500 installed. Right buyer: small to medium home wanting Rinnai service-network advantage at value pricing rather than premium Sensei/RX positioning.
- On-demand operation at 6.6 GPM — no standby heat loss; unlimited hot water if demand is within flow-rate capacity
- 10-year warranty — solid above-average coverage for this class
- Requires dedicated 150K BTU gas supply line — undersized gas piping is the leading cause of flow-rate shortfalls
