EHC Comet 12kW Electric Combi Storage Boiler with 140L Cylinder, EHCCECB12

The EHC Comet 12kW electric combi storage boiler provides wet central heating and domestic hot water from one enclosed unit. It incorporates a 140L duplex stainless steel cylinder and top-entry pipework. The flueless design can fit in a suitable domestic airing cupboard. The 12kW rating sets this version apart from the 9kW and 14.4kW Comet units. Hot water is drawn from the internal storage cylinder, and the packaged layout keeps heating components together. Check cupboard dimensions and the home’s heat load with an installer. The internal cylinder means this Comet model stores domestic hot water rather than relying solely on instantaneous delivery at the tap. Its 140L capacity is shared across the Comet storage variants in this list, while the 12kW figure identifies the boiler heating output. Top pipe connections can simplify routing in a suitable cupboard, but clearance, access for servicing and the electrical circuit must be checked before fitting.
