In this guide, we will break down exactly how this system works, why it might be the perfect fit for your property, and how it compares to traditional gas or oil systems. Whether you are renovating an old home or building a new one, understanding this technology is the first step toward a warmer, more efficient future.

What Is the Electric Heating Company Comet System?

The Comet is not just a boiler; it is a complete central heating solution packaged into a single, compact unit. Manufactured by the Electric Heating Company (EHC), a leader in sustainable heating solutions, the Comet system is designed specifically for properties where space is at a premium or where connecting to the gas grid is impossible or prohibitively expensive.

At its core, the Comet is an electric combi boiler. Unlike traditional systems that require a separate hot water cylinder and cold water storage tank, the Comet heats water directly from the mains supply. This “combi” (combination) functionality means you get instant hot water and central heating from one small box, typically no larger than a standard kitchen wall cabinet.

Key Components of the System

• The Stainless Steel Heat Exchanger: This is the heart of the system, designed for longevity and resistance to corrosion.
• The Pre-Plumbed Cylinder (in some models): While the standard Comet is a combi, EHC also offers systems with integrated thermal stores. The term “pre-plumbed” refers to the fact that the internal components are already connected at the factory. This drastically reduces installation time and the potential for leaks during setup.
• Digital Controls: Modern interfaces allow for precise temperature management and scheduling, essential for energy conservation.

Why Choose a Pre-Plumbed Electric Boiler?

One of the most significant advantages of the Comet system is its pre-plumbed design. But what does this mean for you as a homeowner?

Traditional boiler installations can be messy and time-consuming. Installers often spend hours cutting pipes, soldering joints, and connecting various components on-site. Any error in this manual process can lead to leaks or inefficiencies down the line.

With a pre-plumbed system like the Comet, the complex piping and hydraulic connections are assembled and tested in a controlled factory environment. When the unit arrives at your home, the installer simply connects the inlet and outlet pipes to your existing radiators and mains water supply.

Benefits of Pre-Plumbed Technology

1. Faster Installation: Since the internal plumbing is done, installation can often be completed in a single day.
2. Reduced Labor Costs: Less time on-site means lower labor charges for the homeowner.
3. Higher Reliability: Factory-assembled joints are generally more reliable than those made on-site, reducing the risk of future maintenance issues.
4. Cleaner Aesthetics: The unit is self-contained, meaning fewer exposed pipes and a neater look under your sink or in a utility closet.

How Does the Comet Electric System Compare to Gas Boilers?

For decades, gas has been the dominant fuel source for home heating in many regions. However, the landscape is changing. With the push for decarbonization and the volatility of fossil fuel prices, electric heating is gaining traction.

Let’s look at a direct comparison between the Comet electric system and a traditional gas boiler.

Note: While electric heating is 100% efficient at the point of use, the overall environmental benefit depends on how your local electricity is generated. As the grid becomes greener with wind and solar, electric boilers become increasingly eco-friendly.

For more context on the efficiency of electric heating technologies, you can refer to general resources on electric heating.

Is the Comet System Suitable for Your Home?

Not every home is a candidate for every heating system. The Electric Heating Company Comet electric system and pre-plumbed boiler shines in specific scenarios.

Ideal Use Cases

• Apartments and Condos: Where space is limited and running a gas line is impractical.
• Off-Grid Properties: Homes in rural areas without access to natural gas.
• Renovations: When replacing an old, inefficient electric storage heater system.
• New Builds: Especially those aiming for high energy performance certificates (EPC) ratings.

Considerations for Larger Homes

If you have a very large property with high simultaneous hot water demand (e.g., two showers running at once plus a dishwasher), a standard electric combi might struggle. In these cases, EHC offers larger commercial units or systems with buffer tanks. However, for the average 2-3 bedroom home, the Comet’s output is typically sufficient.

Installation Guide: What to Expect

While you should always hire a qualified professional for electrical and plumbing work, understanding the process helps you prepare. Here is a simplified overview of how a Comet system is installed.

1. Site Survey: The installer assesses your current radiator system and electrical supply. A dedicated electrical circuit is usually required due to the high power draw (typically 6kW to 14.4kW depending on the model).
2. Removal of Old Unit: If replacing an old boiler, it is disconnected and removed.
3. Mounting the Comet: The lightweight unit is secured to a sturdy wall. Because it is electric, there is no need for a flue hole through the wall, preserving your exterior aesthetics.
4. Connecting Water Lines: The pre-plumbed inlet and outlet are connected to your central heating loop and mains water supply.
5. Electrical Connection: A certified electrician connects the unit to your consumer unit (breaker box).
6. System Flush and Fill: The system is filled with water, and inhibitors are added to protect the radiators.
7. Commissioning: The installer tests the pressure, checks for leaks, and sets up the digital controls.

Pro Tip: Ensure your home’s electrical panel can handle the additional load. Most modern homes can, but older properties may need a panel upgrade.

FAQ: Common Questions About the Comet System

1. Is an electric combi boiler expensive to run?

Electricity per kilowatt-hour (kWh) is generally more expensive than gas. However, because the Comet is nearly 100% efficient and requires zero maintenance, the total cost of ownership can be competitive. Using smart controls to heat only when needed is key to keeping bills low.

2. Does the Comet system require annual servicing?

Unlike gas boilers, electric boilers do not produce combustion gases, so there is no legal requirement for annual safety checks in most jurisdictions. However, EHC recommends a periodic check of the pressure and electrical components to ensure optimal performance and warranty validity.

3. Can I use solar panels with the Comet system?

Yes, absolutely. The Comet system pairs excellently with photovoltaic (PV) solar panels. If you generate your own electricity, you can effectively heat your home and water for free during sunny periods, drastically reducing running costs.

4. How long does the Comet boiler last?

Electric boilers have fewer moving parts than gas boilers (no pumps, fans, or burners in the same configuration). With proper care, a Comet system can last 15 to 20 years or more, which is often longer than the lifespan of a standard gas combi boiler.

5. Is the pre-plumbed feature really better?

Yes. It reduces the risk of human error during installation. Factory-tested plumbing ensures that the internal seals are robust, leading to a more reliable system with a lower chance of early-life leaks.

6. What happens if the power goes out?

Like any electric appliance, the Comet will not operate during a power outage. It is advisable to have a backup plan, such as a fireplace or portable heaters, if you live in an area prone to frequent blackouts.
