Indoor High Efficiency Condensing Boilers

With efficiencies of up to 97%, all Warmflow High Efficiency Condensing Boilers easily exceed the minimum requirements of SEDBUK Band A, and therefore operate more economically in comparison to conventional boilers. Warmflow High Efficiency Condensing Boilers are suitable for use on most types of fully pumped heating and hot water systems and are ideal for systems that have been designed to operate with a low return water temperature i.e. under floor heating.

Incorporating the latest Riello RDB2.2 burner and an easy-clean front servicing secondary heat exchanger, with patent pending technology, Warmflow High Efficiency Condensing Boilers have been designed specifically with the needs of the installer and service engineer in mind.


High Efficiency Condensing Utility Series – Standard (UHE)

The Warmflow High Efficiency Condensing Utility Series has been specifically designed to fit into kitchen and utility room applications.  With models starting at only 865mm high and 413mm wide, the High Efficiency Condensing Utility Series is available in Standard, Pumped, System and Combi variants.

Key Features

  • Available in outputs from 15 to 33kW
  • Designed to fit neatly under standard work surfaces
  • Stylish, pre-coated white casing
  • Front servicing
  • Suitable for use with conventional flues or with the multi-optional HE ‘Easy-Fit’ Balanced Flue System
  • Riello RDB2.2 burner fitted as standard
  • Optional 7-day Digital Programmer for mounting within the boiler casing

The Utility Standard Boilers (UHE) are supplied with a pre-wired, factory-fitted burner and thermostat. Only one IE320 mains socket (supplied) needs to be wired on site. The multi-optional flue system can be routed through the top, back, left or right hand side of the casing.

High Efficiency Condensing Utility Series – Pumped (UPHE)

The Utility Pumped Boilers (UPHE) are supplied with a pre-wired, factory-fitted burner, thermostat and circulating pump. Only one IE320 mains socket (supplied) needs to be wired on site. They are also factory-fitted with a 3-Bar pressure relief valve and auto air vent as standard. The multi-optional flue system can be routed through the top, back, left or right hand side of the casing. The Utility Pumped Boilers allow for hassle free, quick and cost-effective installations.

High Efficiency Condensing Utility Series – System (USHE)

The Utility System Boilers (USHE) are supplied as a kit, consisting of a Utility Pumped Boiler (UPHE) (see above) and a System Kit (SK1).

As described above, the Utility Pumped Boiler (UPHE) 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 flue system can be routed through the top, back, left or right hand side of the casing.

The System Kit consists of a pre-assembled 12 litre 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.
