Samsung Mono 10.43kW Heat Pump & Joule Kodiak 250L Cylinder | HXSM-G6-K221 | 3 Zone

Description

This system pairs the Samsung Mono 12kW air source heat pump (10.43kW nominal winter output) with the Joule Kodiak 250L Standard Pre-Plumbed High Gain Cylinder, giving the largest hot water reserve in this 12kW system range for larger households or properties with higher simultaneous hot water demand. 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 3 zones - 1 hot water and 2 heating circuits - from a single compact unit, so radiators, underfloor heating, and domestic hot water can all run to their own independent temperature settings. Built around Samsung's proven Gen 6 R32 monobloc platform, the heat pump operates down to -25°C outdoor air temperature, and the high gain coil in the 250L cylinder is designed for rapid heat-up and recovery even at this larger capacity.

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.

Largest Capacity in This System Range

At 250 litres, this is the highest hot water capacity paired with the 12kW/10.43kW heat pump in this line-up, suiting larger households or higher demand properties.

Factory Pre-Plumbed Cylinder

The 250L 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.

3-Zone Independent Control

The patented modular manifold manages 1 hot water zone and 2 heating zones independently, so radiators and underfloor heating can each run at their own optimum temperature.

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.

High Gain Coil for Fast Recovery

The cylinder's high gain coil is designed for rapid heat-up and recovery even at 250 litres, so hot water demand is met quickly after high usage periods.

Included Immersion Backup

A 2.7-3.0kW immersion heater is built in as a backup or boost option for domestic hot water, alongside the heat pump's primary heating.

Check Ceiling Height Before Ordering

At 1,770mm tall, this cylinder requires adequate ceiling clearance in the plant room or airing cupboard. Confirm available headroom before ordering, particularly in loft or under-stair installations.

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.

How does the 250L option differ from the 170L and 200L versions?

All three share the same 3-zone pre-plumbed manifold and heat pump. The 250L cylinder simply holds significantly more hot water in a taller, narrower stainless steel case, suiting larger households with higher simultaneous demand.

Will this cylinder fit in a standard airing cupboard?

At 1,770mm in height, this is a tall unit. Always confirm available ceiling clearance and floor space before ordering, especially where the installation location has restricted headroom.

What is the lead time on this system?

Please contact us to confirm current stock and lead time before ordering, as availability on combined heat pump and cylinder systems can vary.

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.
