An average gas boiler has a kW size of anywhere between 24-35 kW compared to 15 kW or less for an electric boiler. Boilers are measured in kilowatts (kW), the higher the kW, the more heat and hot water it can provide.Įlectric boilers tend to be less powerful than gas and oil boilers, making them suitable for smaller homes and flats. While most electric boilers are smaller than a gas or oil boiler, it is important to remember that size in this instance refers to how powerful a boiler is, rather than how big it physically is. However, electric boilers can have a limit to the amount of domestic hot water they can produce instantly, which is why an indirect cylinder is often used, especially if the home has a bath.

Electric boilers can be installed to produce hot water for both your heating system and domestic hot water. Also, unlike gas, oil, or LPG, an electric boiler does not produce carbon emissions when working so are seen by many as a more environmentally friendly choice.

This makes electric boilers an ideal option for homes that have no access to mains gas supply or have gas boiler restrictions, such as listed buildings or bed-sits.Įlectric boilers are often fitted in new build homes and flats as they are cheaper to install and maintain. Electric system boilers still give all the benefits of wet central heating without the need for a gas supply.

Where a floor has significant thermal mass and the electricity provider offers time-of-use electricity rates, much heat can be stored when the electricity is cheap to carry its warmth throughout peak electricity tariffs, whereas this is not possible with hydronic.Hydronic can take over a day, meaning more cost and far less convenience, while electric heating is on demand. It is far quicker for electric heating to achieve the required temperature.With hydronic heating, the boiler needs to fire up to warm the water, whether one or all the rooms are in use. The electric system is independently controlled per room, which enables rooms not in use to be switched off.However, this idea was built over time before recent large increases in gas prices and furthermore can be completely negated by additional benefits like Colbuster Advanced Thermostats, as well as the offset through the use of solar energy. There is still a preconceived notion that ongoing heating costs for hydronic are far cheaper than electric.Damage or failure of a hydronic system would result in substantial and expensive consequences, as this could involve significant structural damage to the concrete slab.Electric floor heating has no moving parts or maintenance requirements while the hydronic heating system comprises a boiler, pumps, manifolds with valves with regular maintenance requirements.Compared to hydronic floor heating, the electric installation process is simple and uncomplicated ( DIY suitable ).Labour costs are minimal for electric floor heating.Hydronic is, in essence, a new build process only as it is installed prior to pouring the slab. You can add electric underfloor heating at any time you are altering your flooring. You can easily install electric floor heating to any single room or area, extension or granny flat. Electric is perfectly suited to not only new building projects, but also renovations as well as new rooms.The capital cost of hydronic is far higher than electric.It is important to outline the many benefits electric floor heating has over hydronic, including:
