The multi-optional low-level flue can be positioned to exhaust from the back, left or right hand side of the casing. The Kabin Pak Pumped Boilers allow for hassle free, quick and cost-effective installations.

The Kabin Pak System Boilers (KSHE) are supplied as a kit, consisting of a Kabin Pak Pumped Boiler (KPHE) (see above) and a System Kit.

As described above, the Kabin Pak Pumped Boiler (KPHE) is supplied with a pre-wired factory-fitted burner, thermostat and circulating pump. Only one IE320 mains socket (supplied) needs to be wired on site. The multi-optional low-level flue can be positioned to exhaust from the back, left or right hand side of the casing.

The System Kit consists of a pre-assembled expansion vessel, pressure gauge and filling loop. A pressure hose for connection to the system is also supplied. The System Kit can be connected in only a few minutes creating a sealed heating system.

Models up to 120HE are supplied with System Kit SK1 having a capacity of 12 litres suitable for a maximum total system volume of 145 litres. Refer to BS7074 and the Boiler Manual for further guidance on expansion vessel sizing.

The Kabin Pak Combi Boilers (KCHE) are compact and discreet, yet extremely powerful. Only 600mm wide they are capable of producing over 18 litres of hot water per minute. By utilising the latest twin pump technology and an integral thermal heat store within the boiler casing, the boiler is able to provide plenty of hot water when you need it, as well as helping to keep your heating costs to a minimum.

Where outputs above 44kW are required a Warmflow High Efficiency Condensing Boiler Cascade System is the ideal choice offering the same performance and installation benefits as the other boilers in our range, plus a lot more.

Key Features

• Available in outputs from 52 to 88kW
• More efficient than a traditional single boiler installation
• More reliable than a traditional single boiler installation
• All the benefits of a High Efficiency Kabin Pak Series Boiler

Consisting of two High Efficiency Kabin Pak Series Boilers operating together, the Warmflow Cascade System is inherently more efficient than a traditional single boiler installation however is still capable of achieving an equivalent output. At times of low heating demand, only one boiler usually fires to keep the system hot once up to temperature. At times of high heating demand, both boilers fire together to provide their full combined output.

A Warmflow Cascade System is also more reliable than a traditional single boiler installation. If a fault occurs on one boiler the other boiler is still able to provide hot water and some heating. Should a fault occur on one boiler it can be individually isolated from the electrical supply allowing the 2nd boiler to continue operating.

The Warmflow Cascade System is supplied as a pair of High Efficiency Condensing Boilers with a shopping list of additional required components and detailed instructions on how to plumb and wire the boilers together as a system. There are two Outdoor Cascade Systems available:

K225HE

• Consisting of two K120HE boilers
• Capable of achieving a range of outputs from 52 to 66kW

K300HE

• Consisting of two K150HE boilers
• Capable of achieving a range of outputs from 66 to 88kW
