QuanTec HR28CP has been tested

and CE certified by B.S.I Ltd for use with
LPG G31.

GENERAL DESCRIPTION

2.1

The QuanTec HR28CP appliance is a high efficiency combination boiler, designed to provide both central heating
and domestic hot water on demand. It’s design is room sealed, taking combustion air from outside and expelling
the products of combustion back to the outside.

Standard features include full sequence automatic spark ignition, low water content stainless steel heat exchanger,
automatic bypass and boiler frost protection, a daily pump and divert valve excises.

The

QuanTec HR28CP incorporates an additional recuperator to preheat the DHW cold supply prior to being fully

heated in the normal plate heat exchanger.

Variable CH and DHW temperature controls are fitted on the user control and the boiler features a DHW preheat
facility.

• Central heating (CH) output is fully modulating with a range of: 4.8 to 21.1kW (16,500 to 82,600 Btu/h)
• Instant domestic hot water (DHW) output is also fully modulating with a maximum of: 30.28kW.

2.2

When no demand for CH, the boiler fires only when DHW is drawn off, or periodically for a few seconds without
any DHW draw-off, in order to maintain the DHW calorifier in a heated condition. This only occurs if pre-heat is in
the ‘ON’ period.

When there is a demand for CH, the heating system is supplied at the selected temperature of between 45°C and
80°C, until DHW is drawn off. The full output from the boiler is then directed via the diverter valve to the plate heat
exchanger to supply a nominal DHW draw-off of 12.31 l/min at 35°C temperature rise.

The DHW draw off rate specified above is the nominal that the boiler flow regulator will give. Due to system
variations and seasonal temperatures DHW flow rates/temperature rise will vary, requiring adjustment at the draw
off tap.

At low DHW draw-off rate the maximum temperature is limited to 65°C by the modulating gas control.

The boiler features a comprehensive diagnostic system which gives detailed information on the boiler status when
operating, and performance of key components to aid commissioning and fault finding.
