Thermex Champion Eco horizontal 50 liter boiler, controls on the LEFT

Thermex Champion Eco ER 50H SX – 50 L Horizontal Water Heater with Left-Side Controls

The Thermex Champion Eco ER 50H SX is a robust electric storage water heater specifically designed for horizontal wall mounting. On this SX version, the mechanical controls are located on the left-hand side, making it particularly suitable for installations where the appliance needs to remain easily accessible from the left.

With a nominal capacity of 50 litres, a heating power of 1200 W / 1.2 kW and a compact cylindrical design, the Champion Eco 50H SX provides a reliable solution for everyday hot water supply in homes, apartments, holiday properties and other locations where a vertical water heater is less suitable.

Specifically designed for horizontal mounting

The Thermex Champion Eco ER 50H SX is intended exclusively for horizontal wall installation.

This makes it particularly suitable for areas with limited vertical space, such as:

Under sloping ceilings

High on a wall

Utility rooms

Bathrooms

Technical rooms

Holiday homes

Above other equipment

Areas with limited wall height

With a height of only approximately 445 mm, the water heater requires relatively little vertical installation space.

SX version: controls on the left

On this specific model, the mechanical controls are positioned on the left-hand side.

This is an important difference compared with the DX version, where the controls are located on the right.

When choosing the installation position, sufficient access should therefore be left on the left-hand side for temperature adjustment and maintenance.

50 litre capacity

The Thermex Champion Eco belongs to the 50 litre class and provides a practical quantity of stored hot water for everyday use.

It is suitable for applications such as:

Showering

Washbasins

Kitchen sinks

Small households

Apartments

Holiday homes

Additional hot water supply

By mixing the stored hot water with cold water at the tap, a larger quantity of water at a comfortable usable temperature can be obtained.

1200 W heating power

This specific ER 50H SX version is equipped with an electric heating element rated at:

1200 W / 1.2 kW

The water heater operates on: 230 V

The heating power is not adjustable.

The relatively modest 1200 W power rating can be particularly useful where electrical load needs to be kept lower.

Heating time of approximately 105 minutes

With a temperature increase of ΔT 45°C, the specified heating time is approximately: 105 minutes

The water heater automatically heats the stored water until the selected temperature is reached. The thermostat then switches the heating element off and switches it on again when the water temperature falls.

Mechanical temperature control

The Thermex Champion Eco ER 50H SX uses a simple and reliable mechanical temperature control.

The desired water temperature is adjusted using the rotary control on the left-hand side.

The appliance features:

Mechanical thermostat

Adjustable temperature

Temperature indicator

Overheat protection

No complicated digital controls are required.

Maximum temperature approximately 60°C

For this particular version, the maximum water temperature is approximately: 60°C

The temperature can be adjusted using the mechanical thermostat according to your hot water requirements.

No Wi-Fi or SMART programme

The Champion Eco ER 50H SX is deliberately designed as a simple and robust storage water heater without advanced digital features.

This model has:

No Wi-Fi

No app control

No SMART programme

No weekly programming

No digital display

No anti-legionella programme

The focus is on simple mechanical operation and reliable hot water production.

BIO-glasslined internal tank

The steel internal tank is protected using Thermex BIO-glasslined technology.

The inside of the tank is coated with a special enamel layer that helps reduce direct contact between the water and the steel.

This protective coating contributes to corrosion resistance and helps extend the service life of the internal tank.

Magnesium anode

In addition to the enamelled internal tank, the water heater is equipped with a magnesium anode.

This sacrificial anode provides additional protection against electrochemical corrosion.

For a long service life, the condition of the magnesium anode should be checked periodically in accordance with the maintenance instructions.

Effective thermal insulation

Thermal insulation is fitted between the internal tank and outer casing.

This helps reduce heat loss after the water has reached the selected temperature.

As a result, the heating element needs to switch on less frequently to maintain the stored water temperature.

Energy efficiency class C

The Thermex Champion Eco ER 50H SX has an energy efficiency class C.

It is designed as a straightforward and durable electric storage water heater with mechanical temperature control.

Pressurised electric storage water heater

The Thermex Champion Eco is a pressurised electric storage water heater.

It can be connected to a standard pressurised mains water supply and used with a conventional mixer tap.

The water connections are: ½ inch

3-way safety valve included

A 3-way safety valve / inlet safety combination is included with the water heater.

It performs several important safety functions:

Pressure relief

Non-return function

Pressure discharge during heating

Water expands as it is heated. A small amount of water may therefore drip from the safety valve during the heating cycle. This is normal with a correctly installed pressurised storage water heater.

IPX4 protection rating

The Thermex Champion Eco ER 50H SX has a protection rating of: IPX4

This provides suitable protection against splashing water for its intended installation environment.

Compact horizontal dimensions

The water heater has a compact cylindrical design.

Dimensions:

527 × 459 × 445 mm

Width: 527 mm

Depth: 459 mm

Height: 445 mm

The limited height of only 445 mm is especially useful where vertical installation space is restricted.

Why choose the Thermex Champion Eco ER 50H SX?

The Thermex Champion Eco ER 50H SX is an excellent choice if you are looking for a reliable horizontal 50 litre water heater for an area where installing a traditional vertical model is difficult.

Thanks to its horizontal mounting and compact height of only 445 mm, it is particularly suitable for low spaces, high wall installations and other situations where horizontal wall space is more readily available than vertical space.

The left-side controls make this SX version especially suitable for installations where the left-hand side of the appliance remains easily accessible.

The combination of a BIO-glasslined internal tank, magnesium anode, mechanical temperature control, 1200 W heating element and included 3-way safety valve provides a simple and dependable solution for everyday hot water supply.
