Vitreous Enamel Lined Tank

The Rinnai Hotflo 125L uses a vitreous enamel lined steel tank designed to support long-term durability.

Vitreous enamel lining helps protect the steel tank surface from stored hot water conditions. The system also includes inbuilt anode protection, which helps protect the cylinder as part of the tank’s corrosion protection design.

Correct installation, water pressure control, water quality, valve setup and servicing conditions can all affect hot water system lifespan and warranty outcomes.

Inbuilt Anode Protection

The Rinnai Hotflo 125L Electric Water Heater includes an inbuilt sacrificial anode to help extend the life of the hot water tank.

Anodes are designed to gradually wear over time as part of protecting the cylinder. This makes maintenance and water quality checks important for long-term performance.

Single Element Configuration

The Rinnai Hotflo 125L uses a single element configuration.

Single element electric hot water systems are commonly used for straightforward replacement jobs and can suit smaller households or lower to moderate hot water demand. The correct element size should match the selected model, available circuit, tariff setup and household requirements.

The Rinnai Hotflo 125L lists 1.8kW, 2.4kW and 3.6kW element options.

Internal or External Installation

The Rinnai Hotflo 125L Electric Hot Water System is suitable for internal or external installation where the location is compliant and suitable.

This gives flexibility for homes replacing an existing indoor or outdoor electric storage system. Installation location still needs suitable access, drainage, ventilation, base support, valve setup, electrical connection and compliance with plumbing and electrical requirements.

Dual Handed Connections

The Rinnai Hotflo 125L includes dual handed connections to allow more flexibility during installation.

This can make replacement easier because the water connections can better suit different existing plumbing layouts. Dual handed connection options are useful in like-for-like replacement jobs where matching existing pipework can help reduce unnecessary plumbing changes.

Thermostatic Safety Control

The Rinnai Hotflo 125L is thermostatically controlled and includes automatic safety temperature shut-off.

This helps control stored water temperature and provides added protection as part of the system’s safety design.

125L Electric Storage Capacity

The 125L rated capacity makes this model a practical choice for smaller homes and moderate hot water demand.

It provides more stored hot water than small point-of-use systems while remaining more compact than larger 160L, 250L, 315L and 400L electric storage units.

For higher household demand, a larger electric storage system may be more suitable.

Common Uses

The Rinnai Hotflo 125L Electric Hot Water System can be suitable for:

• Smaller homes

• Units and apartments

• Townhouses

• Granny flats

• Rental properties

• Compact replacement locations

• Electric storage hot water replacement

• Internal or external hot water installations

• Homes needing more capacity than a small 50L system

• Homes where a larger 160L or 250L system is not required
