What is an Electric Combi Boiler?

An electric combi boiler uses electricity to heat water, which is then circulated throughout your home to provide heating.

Unlike traditional gas or oil boilers, electric combi boilers do not use fossil fuels. They don’t produce harmful gases or fumes, making them eco-friendly heating choices.

The ‘combi’ in electric combi boilers stands for ‘combination.’ This means these boilers serve a dual purpose – they provide heat to your radiators and hot water to your taps, eliminating the need for separate water tank system boilers.

Exploring Efficiency Ratings: A Comparative Study

Electric boilers are generally more efficient than gas and oil, with efficiency ratings often reaching up to an impressive 99%.

This means that very little energy goes to waste, as no waste gas escapes through the flue. In comparison, gas boilers are less efficient, typically from 89% to 95%.

However, it’s worth noting that electricity can be three times more expensive than gas. So, while electric boilers consume about half as much energy as gas boilers, they tend to be pricier to run.

When deciding between an electric boiler and a gas or oil , it’s crucial to consider factors such as consumption patterns, output capabilities, and their impact on costs and carbon footprint.

Electric boilers are an eco-friendly alternative to gas and oil since they don’t release CO2 into the atmosphere, which helps reduce carbon emissions.

They are also a viable option for homes that aren’t connected to the gas network, as long as the property isn’t too large and doesn’t have exceptionally high central heating and hot water demands.

Basically, electric boilers boast higher efficiency ratings than gas and oil but have higher operational costs.

When making your choice between these options, it’s essential to weigh factors like energy expenses, environmental impact, and the size and heating demands of your property.

Therefore, it’s crucial to factor in these potential additional costs when considering the overall price of an electric boiler.

Seasonal Factors: Winter vs. Summer

When it comes to electric heating systems, it’s crucial to understand that the seasons play a significant role in how much you’ll end up paying. Ever wondered why your energy bills shoot up during winter? Well, it’s not just because you’re making more cups of tea!

Winter Months: Cranking Up the Heat

In the winter, the demand for heating and hot water is naturally higher. Your electric boiler will be working overtime to keep you toasty. This means the output needs to be higher, and your consumption will increase. So, it’s no surprise that your electric boiler running costs will be at their peak during these chilly months.

If you’re using an electric central heating boiler, you might find that the unit is continually running to maintain a warm temperature throughout your home. This is especially true if your home isn’t well-insulated. Poor insulation means your boiler has to work even harder, pushing your costs through the roof.

Summer Months: A Breather for Your Boiler

Come summer, your electric boiler can finally catch its breath. The demand for central heating drops significantly, and you’ll likely only be using the boiler for hot water. This reduced workload means your consumption will decrease, leading to lower running costs.

However, if you have a separate hot water cylinder, your summer costs might not drop as much as you’d expect. Why? Because maintaining a constant supply of hot water can still be energy-intensive, especially if you love those long, hot showers.

Seasonal Tips: Making the Most of Your Boiler

  1. Insulation: Proper insulation can make a world of difference in both winter and summer. It keeps the heat in during winter and out during summer, reducing the workload on your electric heating systems.
  2. Smart Thermostats: These gadgets allow you to control your heating system remotely, enabling you to manage your consumption more efficiently.
  3. Renewable Systems: Consider integrating solar panels or air-source heat pumps to offset some of the energy costs. These can be particularly effective in the summer months.
  4. Regular Maintenance: Don’t underestimate the power of a well-maintained boiler. Regular check-ups from an engineer can ensure your unit is running efficiently, saving you money in the long run.

Running Costs: Keeping the Heat On

When considering the cost of an electric or gas combi boiler, it’s essential to consider the initial purchase and installation costs and the ongoing running costs.

After all, these running costs will make up most of your expenses over the boiler’s lifetime.

The cost of running an electric boiler in the UK can range from £500 to £1,500 per year, depending on various factors.

These include the boiler’s size, your home’s insulation, and your local electricity rates.

Assuming an average electric boiler output of 12kW and an average electricity rate of 16p per kWh, running an electric boiler for a typical UK household would be around £66 per month.
