Panasonic 3M Weatherproof Box IP55

Designed for Convenient Everyday Use

A.O. Smith FAST-ON combines compact dimensions with instant water-heating performance. It is designed to fit conveniently into suitable bathrooms and kitchens where efficient use of wall space is important.

The choice between 3 L and 5 L capacities also makes it easier to select a water heater according to the intended application and hot-water requirement.

Choose Between 3 L and 5 L

The FAST-ON range gives customers a choice of capacity depending on their requirements. The 3 litre variant offers an especially compact option for quick hot-water requirements, while the 5 litre variant provides additional capacity while retaining a compact wall-mounted form.

Capacity, power rating and installation requirements should be checked before selecting a variant.

High-Powered Heating

A.O. Smith FAST-ON water heaters use high-powered heating elements to provide quick water heating. The 3 L FAST-ON is available in 3 kW and 4.5 kW configurations, while the current FASTON 5L uses a 3 kW heating element.

This range of configurations allows customers to select the appropriate combination of capacity and heating power for their intended application.

Made for Space-Efficient Installation

FAST-ON is designed around a compact form that can fit conveniently into suitable bathrooms and kitchens. This makes it particularly useful where wall space is limited and a compact instant water-heating solution is preferred.

The 3 L and 5 L models have different dimensions, so installation space should be checked against the selected variant before purchase.

Designed for Pressurised Water Systems

The FAST-ON range features pressure-rated tank construction for compatible installations. Pressure specifications vary between versions of the range: the official 3 L FAST-ON documentation specifies an 8 bar rated water pressure, while the current FASTON 5L is rated at 6.5 bar.

Both models are positioned by A.O. Smith for suitable high-rise applications. Always select and install the water heater according to the manufacturer's requirements for the specific variant.

Safety for Everyday Operation

A.O. Smith incorporates safety mechanisms into the FAST-ON range to support dependable everyday operation. The exact safety configuration can vary between model generations and capacity variants, so the specifications and installation instructions supplied with the selected unit should always be followed.

Suitable for Bathrooms and Kitchens

The compact FAST-ON design is intended for suitable bathroom and kitchen installations. Its combination of instant heating and space-efficient construction makes it a practical option where hot water is required without the footprint of a larger storage water heater.
