The EHC Comet PV 14.4kW Electric Boiler & 200L Pre-Plumbed Cylinder Package (EHCEPV14.4/200PPC) combines the field-configurable Comet PV multi-output boiler with a factory pre-plumbed 200-litre Neptune Indirect Unvented Stainless Steel Cylinder. The cylinder arrives with its valves, wiring centre, and circulating pump pre-fitted, cutting on-site installation time versus a standard indirect cylinder, while the boiler's coil-heated indirect recovery still gives faster reheat than a Direct cylinder.
Qualified Installation Required
This boiler must be installed, commissioned, and electrically connected by a qualified electrician in accordance with BS7671. The unvented cylinder is a controlled service under Building Regulation G3 (England & Wales), Technical Standard P3 (Scotland), or Building Regulation Part F (Northern Ireland) and must only be fitted by a competent, G3-qualified installer. A magnetic filter must be fitted to the boiler — failure to do so will invalidate the manufacturer's warranty.
Pre-Plumbed for Faster Installation
The cylinder's automatic by-pass, wiring centre, combination valve, temperature and pressure relief valve, tundish, twin 2-port zone valves, filling loop, and high-efficiency circulating pump are pre-fitted and pre-wired at the factory. EHC estimate this can save up to 70% of installation time on the cylinder side compared with a standard (non pre-plumbed) indirect cylinder fitted with loose components.
Model-Specific Cylinder Performance Data Not Published
EHC's current documentation confirms this pre-plumbed cylinder's capacity (200L) and cased dimensions (1120mm height x 710mm diameter), but does not publish model-specific coil surface area, heat-up time, or weight figures for this exact SKU. Confirm these directly with EHC if required for a design calculation.
Field-Configurable Output
A single boiler chassis covers 7.2, 9.6, 12.0, or 14.4kW via an on-board DIP switch, so installers can right-size the heat output to the building's calculated heat loss without stocking multiple boiler models.
Pre-Wired Cylinder Controls
The cylinder's wiring centre, zone valves, and pump are pre-connected at the factory, reducing the electrical terminations an installer needs to make on site.
Faster DHW Recovery Than Direct
As an indirect cylinder heated via the boiler's primary coil, recovery is markedly quicker than an equivalent-size Direct (immersion-only) cylinder.
Weather Compensation
An outdoor temperature sensor (Tos) lets the boiler's controller adjust flow temperature to a selectable heating curve, reducing energy use during milder weather.
Automatic Anti-Legionella Cycle
A configurable disinfection routine raises cylinder temperature to a set point on a chosen day and time, addressing Legionella risk without manual intervention.
Backup Immersion Heating
The cylinder's 3kW Incoloy immersion element provides electric backup water heating independent of the boiler's primary circuit.
