The Heatrae Sadia Express 7 Oversink Water Heater 95.010.161 provides a convenient 7-litre supply of stored hot water for sinks and basins. Its tough steel case makes it suitable for regular use in domestic, commercial and workplace settings.

A powerful 3kW heating element provides a fast heat-up time of approximately nine minutes for a 50°C temperature rise. Therefore, the Express 7 can quickly recover after users draw hot water from the tank.

The heater comes with a spout and valve for oversink installation. In addition, its adjustable thermostat, dry-start cut-out and long-life alloy-sheathed element support safe and straightforward everyday use.

Important: This product is a vented water heater. The supplied outlet and spout arrangement must remain open to the atmosphere. Therefore, it must not operate as a sealed or pressurised unvented system.

What Comes with the Express 7?

• 1 x Heatrae Sadia Express 7 water heater
• 1 x oversink spout
• 1 x control valve

• Installation template
• Installation and user instructions

The standard package provides the main components needed for oversink installation. However, the installer may need extra pipework, electrical controls or fixings to suit the property.

Where Can You Use the Express 7?

The Heatrae Sadia Express 7 provides local hot water where demand remains relatively low. Its strong outer case and fast recovery make it suitable for locations that need regular handwashing or light washing-up facilities.

• Office kitchens and staff rooms
• Workshops and garages
• Shops and retail premises
• Commercial washrooms
• Schools and community buildings
• Domestic utility rooms
• Garages and outbuildings
• Sinks located far from the main hot water system

This 7-litre model works best for point-of-use sinks and basins. However, it does not provide enough stored hot water for standard showers, baths or other high-demand applications.

Fast 3kW Water Heating

The 3kW element heats the stored water quickly. Heatrae Sadia states a heat-up time of approximately nine minutes for a 50°C temperature rise.

However, actual performance can vary with the incoming water temperature, thermostat setting and electrical supply. A qualified installer must confirm that the circuit can safely support the 3kW electrical load.

Adjustable Water Temperature

The adjustable thermostat provides a temperature range from approximately 5°C to 75°C. Therefore, users can select a suitable setting for the application.

Nevertheless, very hot water can cause scalding. The installer should assess the outlet temperature and fit suitable temperature controls where vulnerable people may use the sink.

Oversink or Undersink Installation?

This product page covers an oversink installation using the supplied spout and valve. The heater sits above the sink and releases expanding water safely through its open outlet.

The Express range can also support certain undersink arrangements. However, undersink installation requires a compatible Heatrae Sadia vented tap pack and suitable accessories. Always confirm the planned arrangement before ordering.

Understanding a Vented Water Heater

A vented water heater does not store water under mains pressure. Instead, the inlet valve controls water entering the tank while the outlet remains open to the atmosphere through the correct spout or vented tap.

As the water heats and expands, small amounts may drip from the spout. This behaviour can be normal. Therefore, users must never block the outlet, fit a restrictive attachment or connect the heater as a sealed unvented system.

Why Choose the Heatrae Sadia Express 7?

The Express 7 combines a tough metal case, simple controls and quick water heating. As a result, it provides a practical point-of-use solution for busy domestic and light commercial environments.

First, the 3kW element provides fast recovery. Next, the adjustable thermostat gives users control over the water temperature. Finally, the dry-start cut-out helps protect the heater if someone switches it on before filling the tank.
