Rinnai V65eN

Rinnai is a Japanese brand that has been manufacturing high-quality appliances for more than 100 years. One of their popular products is the Rinnai tankless water heater, which is known for its energy efficiency, space-saving design, and endless hot water supply. In this article, we will explain what a tankless water heater is, and then focus on the Rinnai V65eN model.

What is a Tankless Water Heater? First things first. Let us explain what is a tankless water heater.

A tankless water heater is a type of water heating system that heats water on demand, instead of storing hot water in a tank.

Unlike traditional water heaters, which consume energy to keep the water hot all the time, tankless water heaters only use energy when hot water is needed. This makes them more energy-efficient, and therefore, cost-effective in the long run.

It is rated by a Uniform Energy Factor (UEF), with highly energy efficient grades. This tankless water heater saves you from expensive power and water costs.


A non-condensing tankless water heater is a type of water heater that does not condense the exhaust gases that are produced during the combustion process. This means that the exhaust gases are vented outside, without extracting any additional heat from them. Non-condensing water heaters are generally less expensive than their condensing counterparts, but they have a lower energy efficiency rating.

Outdoor Installation

The Rinnai V65eN is an outdoor installation model, which means that it is installed outside the building, instead of inside. This is because outdoor installation models do not require venting, and therefore, they are easier to install and maintain. Additionally, the V65eN is designed to withstand harsh weather conditions, thanks to its weather-resistant casing.
