Product Information

Full details

The EHC Comet 6kW Electric Boiler is designed for homeowners seeking an efficient and compact heating solution that minimizes external plumbing. Its key benefit is the integration of essential components like the pump, auto-air vent, and expansion vessel within a single unit, simplifying installation and maintenance. A potential caveat is its suitability primarily for properties where electric heating is the preferred or only viable option. This boiler offers a sleek, discreet design ideal for modern living spaces, incorporating six-stage heating for modulated energy consumption and cost control.

FAQs

What is the power requirement for the 6kW Comet boiler?

The boiler requires a 6kW electrical supply. This may necessitate a dedicated circuit and potentially an upgrade to your home's main electrical intake.

Can this boiler be used for hot water as well as heating?

Yes, it can be configured for both heating and domestic hot water by using an 'S' Plan system in conjunction with the EHC Twin Channel Heatpack. It is not a combi boiler; it heats a stored hot water cylinder.

Does the boiler require regular servicing?

The EHC Comet boilers are designed for minimal maintenance, and no mandatory servicing is required. However, periodic checks by a qualified engineer are recommended for optimal performance and longevity.

How efficient is the Comet 6kW boiler?

The boiler is 100% efficient, meaning all the electricity consumed is converted into heat. Its six-stage heating system further enhances efficiency by modulating power usage based on demand, reducing waste and running costs.

What is the warranty period for this boiler?

The EHC Comet boilers come with a 2-year Parts & Labour Guarantee.

Is the boiler noisy during operation?

No, the Comet boilers are engineered for virtually silent operation, making them ideal for installation in living spaces.

What is the benefit of the integrated magnetic filter?

The integrated magnetic filter is pre-plumbed within the unit to capture metallic debris from the heating system water. This protects the boiler's internal components and helps to enhance its operational life.

Troubleshooting

Boiler not producing heat

Check the power supply to the boiler. Ensure the thermostat is calling for heat and set correctly. Verify that the system pressure is adequate (if applicable) and check for any error codes displayed on the unit.

Low water pressure or slow heating

Check for air in the system and bleed radiators if necessary. Ensure the expansion vessel is correctly pressurized. Inspect for any leaks in the pipework or the boiler itself.

Boiler making unusual noise

A faint pump hum is normal. Loud banging or rattling could indicate air in the system, a loose component, or a potential issue with the pump or heat exchanger. Contact a qualified engineer.

Error code displayed

Refer to the user manual for the specific error code meaning. Common codes relate to sensor faults, over-temperature cut-outs, or pressure issues. Contact a qualified engineer if the issue persists.

Pros and Cons

Pros

  • Compact, all-in-one design reduces installation complexity and space requirements.
  • Integrated magnetic filter protects the system and extends boiler life.
  • Six-stage heating provides efficient modulation to control energy costs.
  • Virtually silent operation ensures a quiet living environment.
  • 100% efficient with low running costs due to modulation.
  • Suitable for both heating-only and combined heating and hot water systems (with additional components).

Cons

  • Requires a 6kW power supply, which may necessitate electrical upgrades in some homes.
  • Electric heating can be more expensive to run than gas in areas with high electricity prices.
  • Domestic hot water provision requires an additional 'S' Plan configuration and EHC Twin Channel Heatpack.
  • Not suitable for properties already connected to a mains gas supply where gas boilers are preferred.
  • Replacement parts may be specific to the EHC brand.

Setup, Compatibility & Care

Setup:

Installation should be carried out by a qualified heating engineer. The boiler is designed to minimize external pipework. Ensure adequate electrical supply (6kW) is available. For heating and hot water, an 'S' Plan configuration with the EHC Twin Channel Heatpack is required. The unit features easy-fit connectors and sensors for straightforward connection.

Compatibility:

  • Suitable for wet central heating systems.
  • Compatible with underfloor heating.
  • Can be configured for heating only or heating and domestic hot water (with additional components).
  • Requires volt-free control connections.

Care:

  • No Mandatory Maintenance: The boiler is designed for minimal maintenance.
  • Periodic Checks: It is advisable to have the system checked periodically by a qualified engineer, especially if any performance issues arise.
  • Cleaning: The exterior casing can be cleaned with a soft, damp cloth. Ensure the unit is powered off before cleaning.
  • Removable Tray: The removable bottom tray should be checked and cleaned as needed to prevent debris build-up.
