Product Description

Ideal Logic Air 150L Slimline Heat Pump Pre-Plumbed 1-Zone Cylinder with CBOX

Model: 236203

PLEASE NOTE: We can only deliver this product to Mainland England addresses. Please read the installation instructions and confirm system compatibility before placing your order.

The Ideal Logic Air 150L Slimline Heat Pump Pre-Plumbed 1-Zone Cylinder with CBOX provides an efficient hot water solution for compatible air source heat pump systems. Its narrow design makes it particularly useful where cupboard width is limited.

Ideal supplies the cylinder with factory-fitted pipework and many of the main hydraulic components. The package also includes the Logic Air control box, thermistors and outdoor sensor. Therefore, it can reduce installation time and create a neat system layout.

The large 1.8m² primary heat exchanger helps transfer low-temperature heat from the heat pump into the stored domestic hot water. As a result, the cylinder can achieve an approximate heat-up time of 22.26 minutes under Ideal’s stated test conditions.

This slimline cylinder has an actual hot water capacity of 145 litres and a narrow 475mm cylinder diameter. In addition, the fitted 3kW immersion heater provides backup water heating and supports anti-legionella cycles.

Please note: This package includes the pre-plumbed cylinder and control box. It does not include the outdoor Logic Air heat pump unless your order specifically states otherwise.

Ideal Logic Air 150L Slimline Dimensions

• Complete Assembly Height: 1598mm
• Cylinder Body Height: 1519mm
• Overall Width: 581mm
• Overall Depth: 606mm
• Cylinder Diameter: 475mm
• Empty Weight: 46kg
• Full Weight: Approximately 192kg

Before ordering, measure the complete installation area rather than using the cylinder body dimensions alone. The factory-fitted components increase the overall height, width and depth.

Your installer must also allow enough room for the expansion vessel, control box, pipework and future servicing. In addition, the supporting floor must carry the full operating weight of approximately 192kg.

What Comes with the Package?

• 1 x Ideal Logic Air 150L slimline pre-plumbed unvented cylinder
• 1 x Logic Air control box
• 1 x 3kW immersion heater
• 1 x heat pump system filter
• 1 x domestic hot water three-port valve
• 1 x pressure and temperature relief valve
• 1 x manual-reset high-temperature cut-out
• 1 x system pressure gauge
• Automatic air vent or vents
• Isolation valves
• Flow and return thermistors
• Domestic hot water thermistor
• Outdoor temperature sensor
• 1 x potable expansion vessel
• Pre-plumbed unvented cylinder inlet controls

The outdoor Logic Air heat pump is not included unless your order specifically states otherwise.

Extra pipework, electrical components, system controls and installation accessories may be required. Therefore, your installer should check the full system design and supplied contents before starting work.

What Does CBOX Mean?

CBOX refers to the supplied Logic Air control box. It contains the main controls and installer connections required to manage the compatible heat pump, hot water cylinder and heating zone.

The control box works with the supplied thermistors and outdoor sensor to monitor system temperatures. It then controls the heat pump and related components according to the selected settings.

However, the control box requires professional installation, wiring and commissioning. The installer must follow Ideal’s latest system schematics and control instructions.

How Does a Heat Pump Cylinder Work?

An air source heat pump usually produces lower flow temperatures than a traditional gas or oil boiler. Therefore, a heat pump cylinder needs a large internal heat exchanger to transfer enough heat into the stored water.

This Ideal Logic Air cylinder uses a 1.8m² heat exchanger. Its large surface area helps the heat pump transfer energy efficiently while maintaining a useful hot water recovery time.

Meanwhile, the unvented cylinder connects directly to the mains water supply. As hot water leaves the cylinder, incoming mains water replaces it. Therefore, the system does not need a traditional cold-water storage tank in the loft.

Standard or Slimline Cylinder?

Choose the slimline model when the available cupboard width limits the use of a standard 550mm-diameter cylinder. This model has a narrower 475mm cylinder diameter.

However, the slimline cylinder is taller than the standard-width 150L model. The complete slimline assembly measures 1598mm high and 581mm wide.

Therefore, measure the available width, depth and height before ordering. Your installer must also allow extra space for controls, pipework and future servicing.

What Does Single Zone Mean?

This cylinder package supports one central heating zone alongside domestic hot water. For example, the heating zone may supply a suitable underfloor heating system or radiator circuit.

A single-zone package may suit properties where all heated areas operate together under one main temperature and time control.

However, properties with separate heating areas may require a two-zone package, low-loss header, buffer cylinder or different system layout. Therefore, ask a qualified heat pump designer to confirm the correct equipment.

Does This Cylinder Include a Buffer Tank?

No. Product code 236203 is a single-zone slimline pre-plumbed cylinder without an integrated buffer tank or low-loss header.

Some heating systems may need extra water volume or hydraulic separation. If required, your installer must specify a suitable separate buffer tank or select another Logic Air cylinder package.

Does This Cylinder Have a Secondary Return?

No. This 150L slimline cylinder does not include a secondary return connection.

If the property needs pumped secondary hot water circulation, ask the system designer to select a compatible cylinder before ordering.

Is a 150L Slimline Heat Pump Cylinder Suitable for My Home?

The correct cylinder size depends on the property and how the household uses hot water. A 150L cylinder may suit some smaller homes with moderate hot water demand.

However, the installer must consider:

• The number of people living in the property
• The number of showers, baths and taps
• The size and type of bath
• Whether several outlets run at the same time
• The selected heat pump output
• The incoming mains water pressure and flow
• The required hot water recovery time
• The planned hot water temperature
• The available cupboard width, height and depth

For this reason, always ask a qualified heat pump designer or installer to calculate the correct cylinder size before ordering.

Installation Requirements

A qualified heating engineer must design and install the heat pump system. In addition, a competent installer with the correct unvented hot water qualification must install and commission the cylinder.

A competent electrician must complete all electrical connections in line with current wiring regulations. These include the control box, immersion heater, heat pump controls, thermistors and outdoor sensor.

In England and Wales, the cylinder installation must meet Part G3 of the Building Regulations. Different requirements apply in Scotland and Northern Ireland.

The installer must also follow Ideal’s latest instructions and approved system schematics. These cover the hydraulic layout, safety valves, expansion vessel, discharge pipework, electrical supplies and control settings.

Why Choose the Ideal Logic Air 150L Slimline Cylinder?

The Ideal Logic Air 150L Slimline cylinder combines efficient heat pump water heating with a narrow design, factory-fitted components and a dedicated control box.

Its 475mm diameter makes it a practical option for narrow installation areas. Meanwhile, the 1.8m² heat exchanger supports fast heat transfer at lower flow temperatures.

Finally, the included filter, valves, thermistors, control box and outdoor sensor provide many of the main components required for a compatible Logic Air installation.
