An electric boiler relies on electricity to generate heat, and they can be highly effective at warming a home or a home’s water supply. An electric boiler tends to be less expensive than gas boilers, but you must do your research on local costs to run an electric boiler in comparison to a gas boiler.
So, you want to heat your home or office and are wondering which option is best when comparing electric boilers vs. gas boilers? To get to the answer, it’s important to ask yourself a couple of questions: Are you installing an entire heating system? If this is you, gas may be the smartest choice.
Heat Only Boilers. Often considered the tradition boiler, heat only boilers require a separate hot water cylinder and cold-water storage tank and are perfect for homes with multiple bathrooms.
These boilers capture additional heat by condensing the moisture in exhaust gases to be ultra-efficient. The problem is that flu gas condensate is very acidic and quickly destroys cast iron and aluminum heat exchangers. Stainless steel is lighter than the others, so it is popular for wall-hung gas boilers.
If its efficiency you seek, in a gas-powered boiler, then the Weil McClain is a perfect solution. Weil MacClain is a leader in heat exchangers, and this model delivers an AFUE 91%. The primary heat exchanger is made from cast iron, and the secondary heat exchanger is made of stainless steel, which enables an exhaust heat energy recovery for increased energy savings.
Exhaust Gas Boilers are normally built to regenerate heat from comparatively large flue gas quantities at a not very high temperature and with a limited pressure loss. To fulfill these demands, the boilers ought to be provided with tubes with extended surfaces on the gas-side.
Exhaust gas boilers (CO-GEN) Over the past few decades, Danstoker has delivered more than 2,500 exhaust gas boilers worldwide and has gained an unparalleled expertise in this field. The boilers are fitted after gas or diesel engines or gas turbines.
Heat exchangers in gas boilers are susceptible to water conditions and combustion by-products which can shorten the life of a boiler or cause it to break down unless annual maintenance is performed. Now no one is claiming that nothing ever goes wrong with electric boilers, but they don’t require a strict maintenance schedule and most issues/problems can be identified with a voltage meter.
Condensing boilers have bigger heat exchangers that already recover much heat from the burning gas, making them more efficient than non-condensing ones. Combi boilers heat water on demand and don’t need a tank to store hot water. How to tell if your boiler is a condensing boiler: If the flue is made of plastic, it’s a condensing boiler.
Heat sources. In a fossil fuel power plant using a steam cycle for power generation, the primary heat source will be combustion of coal, oil, or natural gas.In some cases byproduct fuel such as the carbon-monoxide rich offgasses of a coke battery can be burned to heat a boiler; biofuels such as bagasse, where economically available, can also be used.
Exhaust gas heat exchangers are lagged and cladded in order to prevent heat escaping and to reduce noise emissions from the exhaust. EGHE's differ from exhaust heat boilers that generate steam. EGHE's and Biogas. Care must be taken for biogas applications to ensure the exhaust temperature does not drop below 180C in order to stay above the

Steam boilers operate at a higher temperature than hot water boilers, and are inherently less efficient, but high-efficiency versions of all types of furnaces and boilers are currently available. To learn more about furnaces, boilers and other types of home heating systems, explore our Energy Saver 101 infographic on home heating.
The heat efficiency of a flue gas waste heat boiler is the percentage of the effective heat in the heat injected into the fuel. The anti-balance test method is usually used to measure boiler thermal efficiency.
Exhaust Gas Boilers And Economisers Arrangement Auxiliary boilers on diesel main propulsion ships, other than tankers, are usually of composite form, enabling steam generation using oil firing or the exhaust gases from the diesel engine. With this arrangement the boiler acts as the heat exchanger and raises steam in its own drum.
Exhaust heat from combustion typically leaving the stack and into the atmosphere is instead transferred from the exhaust stream by means of a Cain economizer. This lost BTU is now captured and saved to various heat sinks such as boiler feedwater, cold makeup water, process water, swimming pool water, glycol, and thermal fluids.
And this is 25% more efficient than non-condensing models. Besides, they have a larger heat exchange surface that enables them to transfer as much heat as it is possible, allowing less heat to escape in the form of exhaust gases. Consider all the mentioned benefits and look through condensing gas boilers reviews to pick the model you need.
Danstoker is a world-market leader with expertise in multiple areas, including biomass boilers. Over 80 years we have accumulated an in-depth knowledge of shell and tube boilers, water tube boilers and exhaust gas boilers in general.
Composite Boilers With diesel machinery the amount of heat carried away by the exhaust gases varies between 20 to 25 per cent of the total heat energy supplied to the engine. Recovery of some of this heat loss to the extent of 30 to 50 percent is possible by means of an exhaust gas boiler or water heater.
Exhaust heat boilers are connected to the exhaust of the gas engine and can either be housed in an adjacent building or can be provided in their own customised container. Typical components Containerisation
Space Heating Equipment Overview. Around 75 years ago the steam boiler was considered the premium heating system and only the highest cost homes had them. About 50 years ago it was the hot water or hydronic boiler that was the premium system. About 10 years ago the boiler had all but disappeared from the residential sector.
High Efficiency Gas Boilers High efficiency boilers use the latest in condensing technology to save gas and cut utility bills. Shop our selection featuring Weil-McLain, Burnham, Triangle Tube, and more.
Vertical direct exhaust is a similar installation to the sidewall direct exhaust vented vertically, typically up through the building roof. This heater venting system, typically for gas fired boilers, is used only by certain heating appliance models such as Weil-McLain's CGs boilers.

Aug 13, 2018 · Condensing boilers produce heat by burning natural gas or propane fuel. The word “condensing” refers to the fact that these appliances are able to extract heat from the combustion process so efficiently that the flue gases leaving the boiler are at a much lower temperature than in a conventional boiler.
Dec 09, 2015 · Exhaust gas boiler (EGB or EGE) or economiser described in this article is a smoke tube boiler with steam space, used for heat recovery from main engine exhaust gas. An illustration of the boiler is shown in figure below. The exhaust gas boiler is designed as a vertical boiler with a cylindrical shell surrounding the boiler tubes and water drum as well as the steam space. The tubes consist of a large number of smoke tubes and a small number of stay tubes.
Boiler feedwater economizers are placed in the boiler exhaust stack and heat boiler feedwater after the deaerator and before the boiler. Condensing economizers will have exhaust gas temperatures of between 70°F and 130°F (roughly between 20°C and 60°C), whereas feedwater economizers typically exhaust at well over 200°F (over 100°C).
Burner – The burner is the component of boiler that provides the heat that heats the water of system. The fuels used can be natural gas or oil. Heat exchanger – The heat exchanger of boiler allows the heat from the burner to heat the water in system.
The high efficiency of the condensing boilers results from the fact that heat produced in the condensation process is used to increase heat supply. The exhaust gasses are cooler and hence the maximum condensing happens in the chimney. The condensate then flows along the internal wall of the pressure-tight pipe, and back to the boiler for disposal.
