Samsung Mono 5kW Heat Pump & Joule Kodiak 250L Cylinder | 4.35kW | 3 Zone

Description

This system pairs the Samsung Mono 5kW air source heat pump (4.35kW nominal winter output) with the Joule Kodiak 250L Standard Pre-Plumbed Cylinder, giving Samsung's smallest Gen 6 monobloc unit a generous hot water reserve for well-insulated homes with above-average 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, while the 250L cylinder's high gain coil is designed for rapid heat-up and recovery even at this larger capacity.

Additional Components Are Not Included

This listing covers the Samsung 5kW heat pump and Joule Kodiak 250L 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.

Substantial Hot Water Reserve

At 250 litres, this cylinder gives the compact 5kW heat pump considerably more hot water buffer than the 170L option in the same power band.

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.

Cold-Climate Reliability

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

High Gain Coil for Fast Recovery

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

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 5kW and 4.35kW?

5kW is the unit's nominal summer-rated capacity. In UK winter design conditions (A7/W35), the same unit delivers 4.35kW 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 5kW heat pump and the 250L 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 a 250L cylinder with the smallest heat pump in the range?

This combination suits well-insulated smaller homes with above-average hot water demand - properties whose heating requirement is well served by the compact 5kW unit, but whose household size or usage pattern calls for a larger hot water buffer than the 170L option provides.

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.

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.
