Ideal Icos HE24 System Boiler

Flexibility of siting, ease of installation and advanced reliability all mean that Ideal's high-efficiency heat-only and system boilers offer further improvements on previous models. Thanks to the 80mm diameter twin-pipe fluing feature, which offers a maximum combined fluing length of up to 46 metres that can be run either horizontally or vertically, the icos HE and icos system HE can now be installed much further away from the outside wall. This means the boilers can be fitted safely and unobtrusively in almost any situation. Condensate drainage can be overcome using the optional Ideal condensate pump kit. The icos HE and icos system HE in operation Both products are automatically controlled, fan-flued high-efficiency boilers. They modulate their heat output to suit the demands of the heating load, and both incorporate a variable thermostat for CH temperature control, adjustable from 30°C to 82°C.

The use of a pre-mix burner allows control of gas input to the appliance to be directly linked to fan speed. So, as the fan reduces speed to match heating load, the gas valve maintains the correct proportional flow ensuring a high boiler efficiency throughout its output range.
