How to Choose the Correct Package

HXZ-G605-150SM – 150-Litre Cylinder with 30-Litre Buffer

This option combines the Samsung heat pump with a 150-litre Zenith cylinder and a built-in 30-litre buffer. It may suit households of approximately 1 to 2 people, subject to their hot-water use.

HXZ-G605-180SD – 180-Litre Cylinder with 50-Litre Buffer

This standard-format option provides 180 litres of hot-water storage. In addition, its built-in 50-litre buffer supports systems that require greater buffered water volume. It may suit households of approximately 2 to 3 people, subject to their hot-water use.

HXZ-G605-180SM – 180-Litre Slimline Cylinder with 30-Litre Buffer

This option provides 180 litres of hot-water storage in a slimmer cylinder format. Therefore, it may suit installations where cupboard or plant-room width is limited. It may suit households of approximately 2 to 3 people, subject to their hot-water use.

HXZ-G605-200SD – 200-Litre Cylinder with 50-Litre Buffer

This is the largest hot-water option in the range. It combines a 200-litre cylinder with a built-in 50-litre buffer. Therefore, it may suit households of approximately 3 to 4 people, subject to their hot-water use.

Important: Household size alone should not determine the cylinder choice. Instead, consider the number of bathrooms, bath sizes, shower flow rates and expected peak demand.

Why Choose a Pre-Plumbed Zenith Cylinder?

The Joule Zenith brings key heating and hot-water components together in one organised unit. As a result, it can reduce the amount of separate pipework and assembly required during installation.

Furthermore, the pre-plumbed layout provides a clean and professional finish. It can also make system planning easier because the installer works with a coordinated package.

The integrated buffer adds water volume to the heating circuit. This can support stable heat-pump operation when the system has been designed and commissioned correctly.

Three-Zone Heating and Hot-Water System

These packages are listed as three-zone systems. The hot-water cylinder forms one zone, while the other two zones serve separate heating circuits.

If the property only requires one heating zone, the installer can cap the unused second heating connection. However, the final zoning arrangement depends on the property and system design.

Therefore, confirm the required controls, pumps, valves and thermostats before ordering.

Free Heat-Pump System Design

Choosing the correct heat pump and cylinder requires an accurate heat-loss calculation. Therefore, SNH Tradecentre can help you plan the complete system before you order.

Email your floor plans and project details to darren@snhuk.co.uk. We can then help size the heating system and identify the most suitable pack for your property.

Please include:

• Property floor plans
• Room dimensions
• Insulation details
• Window and door information
• Existing or proposed heat emitters
• Number of bathrooms
• Expected hot-water demand
• Available cylinder-space dimensions

Important Sizing Information

Do not select a heat pump from the property size alone. A qualified designer must calculate the building heat loss and the required operating temperatures.

The designer should also check the radiators or underfloor heating. This ensures the emitters can heat the property at suitable heat-pump flow temperatures.

Likewise, choose the cylinder from the expected hot-water demand. A larger household or property with several bathrooms may need greater storage capacity.

Delivery Information

Delivery for this product range is available to Mainland England only.

These packages contain large and heavy components. Therefore, make sure suitable access is available for delivery. You should also check doorways, paths and storage space before ordering.

Installation Requirements

• Arrange a full room-by-room heat-loss calculation
• Confirm the required heat-pump output
• Check radiator or underfloor heating performance
• Confirm the required cylinder and buffer capacity
• Check the available cylinder installation space
• Confirm the single-phase electrical supply requirements
• Plan the condensate and pressure-relief discharge routes
• Follow all Samsung and Joule installation instructions
• Commission the complete system correctly
• Register the equipment and warranty where required

A qualified heat-pump installer must design, install and commission the complete system. In addition, a suitably qualified engineer must complete all work on the unvented hot-water cylinder.
