As a heating expert with years of experience in the industry, I can provide a comprehensive analysis of the cost-effectiveness of electric central heating compared to gas heating. The comparison between electric and gas heating systems is multifaceted, involving factors such as energy efficiency, installation costs, running costs, and environmental impact.
Energy Efficiency: Gas heating systems are generally more energy efficient than electric heating systems. A gas boiler, particularly a condensing boiler, can achieve efficiency levels of up to 90%, converting a significant portion of the gas used into heat. On the other hand, electric heating systems, such as storage heaters or electric radiators, are less efficient due to the energy losses that occur during the conversion of electricity into heat.
Installation Costs: The installation of a gas heating system can be more expensive upfront compared to an electric system. This is because gas systems require a connection to the gas mains, a flue for ventilation, and often more complex installation work. However, the long-term benefits of a gas system can outweigh the initial costs due to its lower running costs.
Running Costs: This is where the cost comparison becomes more nuanced. As mentioned, electric heating can be more expensive than gas heating. The cost of electricity is generally higher than the cost of gas per unit of energy. Additionally, electric heating systems often require more electricity to produce the same amount of heat as a gas system. However, this can vary depending on the type of electric heating system and the cost of electricity in your region.
Environmental Impact: The environmental impact of heating systems is another important consideration. Gas boilers emit carbon dioxide and other greenhouse gases when they burn gas to produce heat. Electric heating systems do not produce these emissions at the point of use, but the overall environmental impact depends on how the electricity is generated. If the electricity comes from renewable sources, then electric heating can be a more environmentally friendly option.
Heat Pumps: It's important to note that not all electric heating systems are created equal. Heat pumps, which are a type of electric heating, can be highly efficient and cost-effective. They extract heat from the outside air (or ground) and use it to heat your home. Heat pumps can have a coefficient of performance (COP) of 3 or more, meaning they can produce three units of heat for every one unit of electricity consumed.
Maintenance and Repairs: Another aspect to consider is the maintenance and repair costs. Gas boilers require annual servicing and can have more complex repair needs due to their mechanical nature. Electric heating systems, while still requiring maintenance, may have lower ongoing costs in this regard.
Control and Convenience: Electric heating systems can offer more flexibility in terms of control and convenience. They can be easily programmed and controlled, allowing for precise temperature regulation throughout the home.
In conclusion, while gas heating systems are generally more cost-effective in terms of running costs and energy efficiency, the overall decision between electric and gas heating should also take into account factors such as installation costs, environmental impact, and personal preferences regarding control and convenience. It's also worth considering the potential for electric heating to become more cost-effective with advances in technology and changes in energy pricing.

Gas trumps electric storage heaters and oil boilers. ... The basic point is this: using electricity is a shockingly expensive way to heat your home unless you have a heat pump of some sort. At 16p/kWh per unit of usable heat, electric heating is three and half times more expensive than an efficient combi boiler using gas.
