Electric boilers: The complete guide

Welcome to Master Gas London’s thorough introduction to electric boilers. In this guide, we will give you all the important details regarding electric boilers. It covers their background, effectiveness, benefits and drawbacks, as well as factors to take into account when choosing one for your property.

Electric Boiler Overview

Electric boilers are heating units that heat water for both hot water and central heating. They are frequently used to replace conventional gas boilers, especially in buildings without access to gas or without a viable option to install a flue. Electric boilers function by heating the water that is passed through the boiler using an electric element. Radiators or underfloor heating are used to distribute the warm water throughout the building.

Efficiency of Electric Boilers

Electric boilers are renowned for their exceptional efficiency, with up to 99% efficiency ratings. They accomplish this efficiency by efficiently turning almost all of the electricity they utilise into heat. This distinguishes them from gas boilers, which have a lower efficiency rating because they can lose heat through the flue. The higher efficiency dpes not mean an electric boiler will save you money as electric is more expensive than gas. Electric combi boilers are known to quite expensive to use on a daily basis.

Pros of Electric Boilers

Energy Efficiency

One of the biggest benefits of electric boilers is their energy efficiency.

Easy to Install

Easy to install and maintain, as they don’t require a gas supply or a flue.

Reduced Carbon Emissions

Electric boilers don’t rely on burning fuel to generate heat for water, resulting in zero emissions that would require a flue for ventilation. This feature makes electric boilers a safer and more environmentally-friendly heating option.

Cons of Electric Boilers

Expensive to Run

The main disadvantage of having an electric boiler is that they are expensive to run on a daily basis in comparison to a gas boiler.

Low Flow Rates

Electric boilers also have a lower flow rate than gas boilers, which means that they may struggle to meet high demand for hot water.

Things to Consider

When choosing a electric boiler, there are a few other things to consider:

 

Size: The size of your electric boiler should be based on your property’s heating requirements, which a qualified heating engineer can determine.

 

Installation: electric boilers require professional installation to ensure they are installed safely and correctly. 

 

Electric Supply: To install an electric boiler you will need an electrician to check the supply to the boiler and in most cases upgrade the breaker on the consumer unit and the cable to supply the boiler.

 

Cost of Electric: You’ll also need to consider the cost of electricity in your area, as this will affect how much you pay to run your boiler.

Summary of Electric Boilers

Electric boilers present a practical and energy-efficient solution for homes and businesses that cannot access gas or do not have a viable flue option. They are user-friendly and straightforward to maintain, making them an ideal choice for properties with restricted space. Even though electric boilers have a higher efficiency rating they do have a higher running cost compared to gas boilers. Nevertheless, electric boilers still present a viable option if you have no gas supply or an option for a flue.

I had received an extortionate quote from another company and wanted to compare it to Master Gas London. I spoke with Ed and he was so knowledgable and honest. He took the time to explain the different boiler options and let me know the pros and cons of the different boilers. He was very patient and I am so appreciative of the time he took with regards to the choices I could make. It is such a shame I am located too far away to use this company, as their professional response and advice was outstanding.

Highly recommend. Could not fault Ed and Tamer. They were efficient, on time, went out of their way to ensure we were pleased with the work, and took time to explain the new system. The work was finished to a high standard and all pipework routed beautifully.

I was very anxious about my boiler to be fixed properly until I found Ed from the first telephone call, my anxiety has been eased off immediately because he was so polite, explained potential issues and he tried to book me in as quickly as possible even though he is very busy. He was so professional from beginning to end. At the site he investigated the problems and explained to me the issues and he didn’t leave until everything was sorted out properly. Today I was able to take a comfortable bath for the first time in a long time. Thank you Ed. Highly recommend and will definitely recommend to my friends!

Ed and team came to install a new boiler a few months back and I've been meaning to leave a review ever since because they were so great. Worked all day and didn't leave us until everything was working. They are more than happy to stay in touch if there's any follow ups too which is great.

FAQ'S

An electric boiler is a type of heating system that generates heat using electricity rather than fuel. It heats water or provides heating in a building without the use of a chimney to emit emissions.

Electric boilers use electricity to heat a heating element, which then heats water that is circulated throughout the property. The heat generated is in turn transferred to the water in either the heating system or to provide hot water.

Electric boilers have efficiency rates of up to 99% because they almost entirely convert the electricity they consume into heat, producing very little waste. It is important to note that while having a better efficiency rating than gas boilers it does not mean electric boilers are cheaper to run.

The cost of running an electric boiler will heavily depend on the type of tariff you are on. If you are on a high tariff an electric boiler will be very costly to run on a daily basis.

Yes, electric boilers are safe to use. Since they do not burn fuel to generate heat, they do not produce harmful emissions that need to be vented outside through a flue. They also have safety features that prevent overheating and other hazards. The main safety hazard is incorrect installation, the wiring and electrical supply must be done by a qualified electrician.

The lifespan of an electric boiler can vary depending on the model and how well it is maintained. However take note that electric boilers do tend to be sold with low warranty options.

yes, electric boilers can be used to provide both heating and hot water. Some models are specifically designed to provide both functions.

Electric boilers are quieter than gas boilers as they do not have a combustion process that generates noise. They typically operate silently, making them a great option for properties where noise is a concern.
