Rinnai 17e LPG Gas Water Heater

The Rinnai Infinity 17e is an instantaneous multipoint LPG water heater. Instead of storing a large volume of hot water, it heats water as it passes through the appliance.

This continuous-flow design makes the Rinnai 17e relevant to customers looking for:

• Rinnai LPG water heaters
• External LPG water heaters
• Outdoor LPG water heaters
• Rinnai 17e propane water heaters
• LPG tankless water heaters
• LPG instantaneous water heaters
• Continuous-flow LPG water heaters
• Low-NOx LPG water heaters

The manufacturer’s specification identifies both natural-gas and LPG versions under the W17E(A) range, with W17E(A)-LPG being the LPG configuration.

External Installation

A major feature of the Rinnai 17e is its external installation format.

Rinnai describes the 17e as an external water heater that can provide greater flexibility where internal space is unavailable or where indoor flue routing presents a challenge.

Because the appliance is designed for outdoor installation, the installation location should be selected according to the manufacturer’s clearances, gas regulations, terminal requirements and protection requirements.

Low-NOx LPG Technology

The Rinnai 17e uses Low-NOx combustion technology.

Rinnai’s published specification gives a NOx figure of approximately 50 mg/kWh for the 17e.

This makes the product relevant for searches such as:

• Low-NOx LPG water heater
• Low-NOx gas water heater
• Rinnai Low-NOx water heater
• external Low-NOx water heater
• LPG Low-NOx water heater Europe

Rinnai 17e Flow Rate

The Rinnai 17e specification lists a maximum flow rate of 20 L/min. It also specifies approximately 12.3 L/min at a 33°C temperature rise.

Actual hot-water flow depends on:

• Incoming water temperature
• Required outlet temperature
• Water pressure
• LPG supply
• Temperature rise
• Number of simultaneous outlets
• System design

Therefore, the product should not be described as having a fixed 17-litre capacity.

Important terminology

17e refers to the model designation.

It does not mean the appliance contains a 17-litre hot-water storage tank.

For SEO and technical accuracy, use:

“up to 20 L/min maximum flow”

rather than:

“17L capacity.”

Hot-Water Temperature Control

The Rinnai 17e provides electronically controlled hot water within its specified temperature range.

Rinnai’s current documentation lists temperature settings from approximately 37°C to 65°C, with temperature accuracy of approximately ±1°C.

The correct temperature should be selected according to the intended application and applicable safety requirements.

Frost Protection

The Rinnai 17e incorporates frost protection for suitable outdoor installations.

Rinnai’s product information specifically highlights full frost protection as a feature of the 17e external water heater.

The installation still needs to follow the manufacturer’s requirements for pipework, water connections, electrical supply and environmental conditions.

Rinnai 17e vs Rinnai 17i

The distinction between these two models is particularly important when customers are comparing Rinnai LPG water heaters.

Rinnai’s current specifications confirm the 17e as an external/outdoor unit, while its 17i is the internal wall-mounted model.

For customers who specifically require an indoor installation, the Rinnai 17i should be evaluated instead.
