Save Energy with Electric Combi Boilers

Having a good boiler makes a big difference in a household, especially in a country that gets as cold as the UK during winter. When it comes to choosing the right type of a boiler, electric combi boilers are an efficient and quiet way to heat up your rooms and simultaneously provide hot water.

An electric combi boiler is a great choice if you need to replace your old gas or oil boiler. It is a much cleaner solution in itself since it doesn't release any gas into the atmosphere, and is suitable for homes that do not have the extra space for storing the oil tank. Electric combi boilers come in a variety of different sizes and can be placed conveniently in your kitchen or laundry cupboard.

Using an electric combi boiler is a smart choice since it doesn't require much maintenance and is a perfect decision for those who have no access to the gas grid. Furthermore, installing and maintaining an electric combination boiler is considerably cheaper than installing and maintaining a gas or oil boiler.

Electric Combi Boiler Running Costs

It is estimated that the annual cost of using an electric combination boiler is around £1,800. However, for a 210-litre Thermaflow model, the annual cost is £2,025. The result is based on a total of 13,500 kWh at 15 pence per kWh.

Although it might not be the cheapest heating technology regarding running costs, electric boiler installation costs are much lower than those of gas boilers and they do not need annual maintenance or safety inspections. You can even apply for receiving a free boiler replacement.

Look at the following table that compares two types of combi boilers and their running costs. The numbers are considered for a 3 bedroom-flat with 4 residents. The annual costs were calculated with a presumption that 1 kWh of gas costs 4.38 pence and 1 kWh of electricity is 13.58 pence.

Electric Combi Boiler vs. Gas Combi Boiler
Heating  Gas central Electric plug in
Boiler Type Combi Combi
Water Heating Gas Electricity
Annual Gas Consumption 12,237 kWh n/a.
Annual Electricity Consumption 4,448 kWh 12,366 kWh
Annual Consumption Costs £1,145 £1,679

Even though you can see that the running costs of electric combi boilers are higher, there are more additional costs to consider in case of gas combi boilers. When choosing an electric combi boiler, you save money on not having to pay for the yearly gas certificate.

Additionally, the regularity of repairs needed decreases, and even though gas is quite cheap per unit, the efficiency is lower than with electric boilers as it burns more gas than it needs for creating heat that should not be paid for in the first place. What is more, the government tries to financially support any type of green investment you choose to make regarding your home.
