Samsung Mono 12kW Heat Pump & Joule Kodiak 300L Cylinder | HXSM-G6-K2221 | 4 Zone

Description

This system pairs the Samsung Mono 12kW air source heat pump (10.43kW nominal winter output) with the Joule Kodiak 300L Standard Pre-Plumbed Cylinder, combining the mid-range 12kW heat pump with the largest cylinder and most heating zones in this system range - suited to larger or more zoned homes that don't need the full 16kW heat pump capacity. The Kodiak cylinder arrives factory pre-plumbed with its zonal control manifold already fitted, cutting installation time compared with plumbing a heat pump to a standard cylinder on site.

The patented modular zonal control manifold manages 4 zones - 1 hot water and 3 heating circuits - from a single compact unit, allowing radiators, multiple underfloor heating areas, and domestic hot water to each run to their own independent temperature settings. The heat pump operates down to -25°C outdoor air temperature, and the 300L cylinder gives substantial hot water reserve for larger households.

Additional Components Are Not Included

This listing covers the Samsung 12kW heat pump and Joule Kodiak 300L Standard cylinder only. Items such as the potable expansion vessel, Y strainer with isolation valve, braided hoses, anti-vibration feet, and heat pump fluid are not included and should be ordered separately to complete the installation.

MCS-Certified Installation Required

Installation must be carried out by an MCS-certified installer to ensure compliance with UK regulations, to qualify for available government funding schemes such as the Boiler Upgrade Scheme, and to validate the full manufacturer warranty on both heat pump and cylinder.

Long-Term Warranty Cover

The heat pump carries a 7-year warranty when commissioned by Joule or a trained installer, while the Kodiak cylinder body is covered for up to 25 years with registration, and its components for 2 years - giving strong long-term protection across the whole system.

4-Zone Independent Control

The patented modular manifold manages 1 hot water zone and 3 heating zones independently, supporting more complex heating layouts than the 3-zone 200L and 250L options.

Largest Cylinder Paired with the 12kW Unit

At 300 litres, this gives the 12kW heat pump substantially more hot water reserve than the 170L, 200L, or 250L Kodiak options in the same power band.

Factory Pre-Plumbed Cylinder

The 300L Kodiak arrives with its hydraulic and zonal control manifold pre-fitted, cutting on-site plumbing time compared with a bare cylinder and separate control kit.

True Monobloc Heat Pump

Samsung's Gen 6 outdoor unit has the entire refrigeration circuit factory-sealed, removing the need for on-site F-Gas handling.

Cold-Climate Reliability

Rated to operate continuously down to -25°C outdoor air temperature, maintaining heating output through UK winters.

Mid-Range Capacity with High-End Cylinder

Suits properties needing 12kW-level heating but with hot water demand or zoning requirements closer to those served by the larger 16kW systems.

Check Ceiling Height Before Ordering

At 2,040mm tall, this is the tallest cylinder in the range and requires substantial ceiling clearance in the plant room or airing cupboard. Confirm available headroom carefully before ordering.

Why is the heat pump rated at both 12kW and 10.43kW?

12kW is the unit's nominal summer-rated capacity. In UK winter design conditions (A7/W35), the same unit delivers 10.43kW of usable heating output, which is the figure most relevant for sizing against a property's actual winter heat loss.

What comes in the box with this system?

This listing includes the Samsung 12kW heat pump and the 300L Kodiak Standard cylinder only. Additional components - expansion vessel, Y strainer, braided hoses, anti-vibration feet, and heat pump fluid - are not included and should be ordered separately.

Why pick 12kW with a 300L cylinder rather than the 16kW system?

This combination suits properties whose heat loss is well served by 12kW but whose hot water demand or zoning needs (4 zones, larger cylinder) are closer to what the bigger 16kW systems in this range provide.

Will this cylinder fit in a standard airing cupboard?

At 2,040mm in height, this is the tallest cylinder in the range. Always confirm available ceiling clearance and floor space carefully before ordering, especially in loft or restricted-headroom installations.

Is MCS certification required?

Yes. Installation should be carried out by an MCS-certified installer to comply with UK regulations, access funding schemes such as the Boiler Upgrade Scheme, and validate the manufacturer warranty.
