3.1 Different Energy Source

The primary difference between electric steam boilers vs gas steam boilers lies in their energy sources. Electric steam boilers rely on electricity as their energy source, while gas steam boilers utilize natural gas or propane as their fuel.

3.2 Different Boiler Efficiency

Electric steam boilers generally exhibit higher efficiency ratings than gas steam boilers. This is because electric boilers can convert nearly all the electrical energy they consume into heat energy, resulting in minimal energy loss. On the other hand, gas boilers may experience some energy loss during the combustion process, which can reduce their overall efficiency.

3.3 Different Heat Generation Method Of Electric Steam Boiler vs Gas Steam Boiler?

Electric steam boilers generate heat through electrical resistance heating elements. These elements convert electrical energy into heat energy, which is then transferred to the water to produce steam. On the other hand, gas steam boilers employ a burner to combust natural gas or propane, producing a flame that heats the water and generates steam.

Gas steam boiler

• Fuel combustion: Fuels such as natural gas or propane are burned in the boiler to produce high-temperature combustion gases.
• Heat transfer: The heat of the combustion gases is transferred through the combustion chamber wall to the water in the water pipe.
• Water heating: Water circulates in pipes and reaches the boiling point to produce steam after being heated.
• Steam Generation: The generated steam is collected in a steam drum and then transported through pipes to where it is needed.

Electric Steam Boiler

• Electric heating element: The boiler has a built-in electric heating element that generates heat energy through current heating.
• Heat transfer: The heat energy generated by an electric heating element is transferred through direct contact with water.
• Water heating: Water is heated to the boiling point, producing steam.
• Steam generation: The generated steam is released directly into the steam system for supply.

3. 4 Different Environmental Impact

Electric steam boilers are considered more environmentally friendly as they produce zero emissions at the point of use. However, the overall environmental impact depends on the source of electricity generation. If electricity is derived from renewable sources, the environmental impact is further reduced. In contrast, gas steam boilers emit combustion byproducts, including greenhouse gases, contributing to air pollution and climate change.

3.5 Installation and Operation

Electric steam boilers are generally easier to install and operate compared to gas steam boilers. Electric boilers do not require a flue or chimney for exhaust gases, and they have fewer safety considerations related to fuel storage and combustion. Gas boilers, on the other hand, require proper ventilation and exhaust systems, and compliance with safety regulations regarding the storage and handling of gas fuel.

3.6 Different Cost

The cost comparison between electric and gas steam boilers depends on various factors such as the local energy costs, boiler size, and usage patterns. In some regions, electricity may be more expensive than natural gas, making gas steam boilers more cost-effective.

Lower fuel costs: 

In many countries, natural gas, or other gaseous fuels, tend to be cheaper than electricity, which eliminates the need for fuel storage and reduces transportation costs, especially in cities where natural gas prices are lower.

4.4 Disadvantages of Gas Steam Boiler

Installation Complexity

There is a prerequisite when using a gas fired steam boiler, that is, the local natural gas pipeline needs to be opened. Only when the natural gas pipeline is connected can we connect the boiler. However, gas boilers cannot be used in remote areas, which will increase the complexity of the installation process.

Space Requirements

There are natural gas pipelines installed locally, indicating that we can install and use gas fired steam boilers, but combustion boilers usually require more installation space, including ventilation systems and gas pipelines, which may be limitations of smaller or narrow spaces.

Air supply is tight

After the gas fired steam boiler is debugged in accordance with the regulations, if it is a steam boiler, it needs to go to the local quality inspection department for inspection and acceptance. Only after passing the acceptance can it be operated. After the gas steam boiler can be used, the use of natural gas will be restricted when facing a tight gas supply. This will cause the gas fired steam boiler operating time to be unguaranteed and affect work efficiency.

Both gas steam boilers and electric steam boilers of EPCB Boilers have unique advantages and considerations. The choice between them depends on factors such as cost, efficiency, environmental impact, and specific application requirements. EPCB Boilers offer a range of options and expertise to help customers choose the boiler system that best suits their needs.

5. Which One Is Better Between Electric Steam Boiler vs Gas Steam Boiler?

When you are choosing a steam boiler system for your factory or production, both electric steam boiler and gas steam boilers are viable options, but they each have different characteristics and applicable scenarios. Gas steam boilers are mainly suitable for large industrial production lines or processes that require a large amount of heat energy supply. However, gas steam boilers will produce greenhouse gas emissions such as carbon dioxide during the combustion process, which will have a certain impact on the environment.

In comparison, electric steam boilers have more advantages in energy efficiency and environmental protection. Especially when the electricity comes from renewable energy sources, electric steam boilers not only cause no carbon emissions, but also achieve efficient energy use. They usually have more precise temperature control and regulation capabilities and are suitable for delicate processes with higher temperature requirements. However, the heat output range of industrial electric boilers may be relatively low and may not be able to meet the heat energy needs of some large industrial processes.

Therefore, among the two types of industrial steam boilers, you need to choose based on the production process, heat energy demand and energy demand. If an electric steam boiler can meet production needs and uses green or alternative energy, then it is indeed an environmentally friendly and viable option.

In Finland, the rise in biofuel prices coupled with simultaneous high demand has catalyzed a shift towards electric boilers for process steam production. This transition not only responds to economic pressures but also aligns with an increasing commitment to environmental sustainability.

Electricity, particularly when sourced from expanding wind energy investments, offers a cleaner, competitive alternative to traditional energy sources. This change has also been facilitated by the power exchange market, which allows taking advantage of fluctuations in electricity spot prices, making boilers an economically attractive option.

The demand for biofuels has accelerated as the pulp industry and the energy sector have started to compete more for the same wood resource. New strategies are needed to ensure that there will be enough biofuels in the future while maintaining companies' commitment to zero-emission production.

Here, heat pump and electric boiler solutions can offer an alternative to solid fuel-based steam and hot water production, and both technologies are widely applied in both the industry and at district heating plants.

The electrification of heat production in Finland is boosted by investments in wind energy infrastructure, which help transition electricity to being nearly emission-free.

According to energy consultancy company Motiva, Finland's wind turbines already produced 14.4 TWh of electricity in , which corresponded to approximately 18 per cent of Finland's electricity consumption. On the other hand, electricity production in Finland is already almost 94% emission-free according to Finnish Energy.

However, as the availability of electricity and its price fluctuate, electric boiler implementations may sound like madness.

According to Adven's energy experts, electric boilers are particularly suited for sites where there is no local heat source, for instance residual or geothermal heat, from which the required heat could be retrieved with a heat pump or if the need for heat temperature is higher than what can be achieved with heat pumps.

basically any application.  

As fuel prices have risen, it has become practical to consider electric boilers alongside traditional energy production. Depending on the situation, they can be utilized for base or peak loads. Due to their emission-free nature and cost-effectiveness, electric boilers offer significant advantages, especially in sites where energy is still produced with fossil fuels.

Most of the operating costs of an electric boiler come from the price of electricity itself. When considering this, it is good to look at possible own electricity production, what part of the electricity price is hedged and what kind of savings in transmission costs could be achieved by connecting to a higher voltage network. In addition, the efficiency of alternative forms of heat production should be considered. Against this background, an electric boiler is always more expensive in terms of operating costs than a heat pump, even if it is significantly cheaper as an investment.

In terms of maintenance efficiency, the electric boilers are relatively easy and simple to handle. Especially since the implementation does not require maintenance heavy fuel reception facilities, nor does it need to worry about fuel quality.

The planning of the solution starts in the same way as in any other Adven's sales cases: a comprehensive review determines how the customer's energy needs can be met while minimizing overall energy use and emissions. In energy modelling it is examined whether heat can be recovered from the process and/or produced with heat pumps.

If these options are not possible, the boiler solution that is most suitable for the project is reviewed. For this, it is necessary to know the basic energy needs, i.e. whether hot water or steam is needed and how much energy the customer's process requires now and in the future. Once these issues are clear, different options are evaluated and from this evaluation an electric boiler could be selected as the right solution.

Adven's customers do not have to worry about these aspects. The Energy as a service® conceptcovers everything from design and project management to financing and operations and maintenance throughout the lifetime of the solution.

Special consideration in the electric boiler cases should be given to the available electricity supply, i.e. if the electrical substation does not have the needed electricity capacity required by the boiler, or the supply cannot be profitably strengthened due to too long distances, then an electric boiler is not the best option.

Water chemistry is also important in electric boiler implementations. Depending on the type of boiler, special attention should be paid to the quality of the feed water to ensure that the conductivity of electricity in the water is suitable for the boiler and that there will be no problems with the boiler structures and piping during the service life.

Feed water can be treated, for example, from recovered water from the customer's processes or from the water received from municipal network.
