This system pairs the Samsung Mono 12kW air source heat pump (10.43kW nominal winter output) with the Joule Kodiak 200L Standard Pre-Plumbed Cylinder, giving a complete heating and hot water solution sized for medium UK homes with slightly higher hot water demand than the 170L option. 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 with a 7-year warranty available on both heat pump and cylinder.

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.
Factory Pre-Plumbed Cylinder
The 200L 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.
More Hot Water Headroom Than 170L
At 200 litres, this cylinder gives extra buffer for households with higher simultaneous hot water demand than the 170L option comfortably covers.
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.
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.

Standard vs Slimline Footprint
This 200L Kodiak is the standard-profile cylinder (840mm diameter), not the slimline version. If your installation has a restricted footprint, confirm which 200L variant is required before ordering, as Joule also offers a narrower slimline 200L option with a taller, smaller-diameter case.
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 200L option differ from the 170L version?
Both share the same 3-zone pre-plumbed manifold and heat pump. The 200L cylinder simply holds 30 litres more hot water, in a larger-diameter, standard-profile case, suiting homes with slightly higher simultaneous hot water demand.
Is this cylinder suitable for a home with underfloor heating and radiators?
Yes. The 3-zone manifold is designed to run 1 hot water zone and 2 independent heating zones, making it well suited to properties combining underfloor heating in some areas with radiators elsewhere.
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.
