The Comet Electric Combi Boiler offers the comfort and convenience of wet central heating and domestic hot water for domestic properties with no access to mains gas.

It is a fully packaged unit that is housed in an elegant enclosure which is compact in size (height 1745mm, depth 628, width 581mm) and has been designed to fit into a standard domestic airing cupboard. To maximise space and minimise installation the unit has been designed with top entry pipework. This makes it ideal for a range of properties as there are no flue requirements.

The Comet Electric Combi boiler has been designed to come complete with;

  • The option of a 9kW, 12kW or 14.4kW stainless steel heat exchanger;
  • Automatic air vent;
  • High thermal cut out;
  • Digital pressure gauge;
  • Vortex flow sensor;
  • 140 Litre Indirect Stainless Steel Hot Water Cylinder;
  • Pre-plumbed using the ‘S’ Plan configuration
  • In-built magnetic filter for boiler protection;
  • Pre-wired Zone Valves;
  • Expansion Vessels for both Heating and Hot Water circuits;
  • Drain valve, T&P relief valve and Automatic By-Pass;
  • Connection for back up Immersion;
  • Integral system diagnostics.

It is also supplied with an external Tundish and Domestic Hot Water Control Valve and a fully programmable Twin Channel Controller and Room Thermostat to provide full control of both the Central Heating and Domestic Hot Water.

The ‘S’ Plan configuration enables you to select Heating only, Hot Water only or both at the same time.  As the boiler is also heating the Indirect cylinder, the re-heat times for the Hot Water is superior to that of a Direct Cylinder comprising of an Immersion Heater only.

The Combi Boiler has an easy-to-use control panel which allows;

  • both the installer and home owner to identify the operating temperatures on the flow and return, system flow rate and kW output of the boiler at any given time;
  • the installer to utilise the inbuilt self-diagnostic feature during installation or routine maintenance;
  • the operating temperature of the boiler to be adjusted from 40 degrees through to a maximum 85 degrees.

The digital pressure sensor within the unit allows you to take an accurate reading of the system pressure at all times.
