The Ultimate Glossary Of Terms About Multi Fuel Boiler Stove

Multi Fuel Boiler Stove

Multi fuel boiler stoves are designed to burn a range of fuels including smokeless fuel, logs and coal. They can be 'linked' to your existing heating system to reduce costs.

When burning coal, the grate must to be removed in order for air to enter the fire from below. Some multi-fuel stoves come with riddling grates and asphans to make this process easier.

Energy Efficiency

A multi-fuel stove can burn a range of different types of solid fuels, including peat and turf Briquettes, smokeless coal, and anthracite. They can also burn logs. They are more adaptable than wood-burning stoves because they can be used with a range of fuels.

Most modern Ecodesign stoves that are compliant have an efficiency of 80 percent or more. They can help meet the SAP energy needs by generating low CO2 emissions. A lot of homes in the UK make use of a wood-burning multi fuel stove to heat their living areas and also have central heating systems (either gas boiler or hot water cylinder) as the primary source of primary heating. It is typically complemented by a second type of heating, such as an air or convection hot water stove.

cast iron multi fuel stoves uk  of the stove is crucial because it shows the amount of heat that is delivered to your home. It is not to be confused with the efficiency of combustion which is the figure that appears on the back of a stove. The efficiency of combustion is based on how efficient the stove was in an experiment in the laboratory. It does not reflect efficiency of the entire system comprising chimney, fuel and stove.

Stove manufacturers frequently refer to combustion efficiency, not System Efficiency on their marketing material This is a mistake. System Efficiency is not a measurement of the stove's performance in a test conducted in a lab. It is a calculation based on the total emissivities of both the stove and the fuel in a home.

It is important to note that the TE for the specific combination of fuel and stove is determined by the volatile matter content of the solid fuel since it will determine if particulate-bound pollutants (e.g. PM2.5, EC and BaPeq) are emitted during the ignition of the fuel or if they are retained during the pyrolysis stage. If the volatile matter remains in the pyrolysis phase it releases carbonaceous particles that aren't bound effectively and contribute to the total emissivities.

Low Maintenance

In contrast to catalytic stoves that have to be constantly monitored Non-catalytic multi-fuel stoves are designed to be simple to operate and require minimal maintenance. They are less expensive and use an air-combustion system that is pre-heated to improve the performance of the stove. These models can burn a variety of solid fuels like smokeless coal and have an air control that lets you manage the speed at which the fire is burning. This lets you create more efficient and efficient fire with more flame distribution and less emissions.

You'll need to replenish your stove every 10-14 hours, based on the way you use it. You'll also have to empty the ash pan often. If you use smokeless coal then the ash must be cleared to prevent it from blocking the air passages that are used for combustion, and thereby denying the fuel oxygen. This can be accomplished with the tool that looks like a pitchfork.

BTU ratings are an excellent indicator of the performance of a multi-fuel boiler stove. However, they shouldn't be the only thing you compare when comparing models. Other factors such as the size of the burner and weight can have just as significant an impact on overall performance.

Modern multi fuel stoves can be used with a broad variety of liquid fuels including white gas, isobutane and Kerosene. This makes them ideal for backpacking trips, particularly in remote regions where canister fuel may not be readily available.

Multi-fuel liquid-fuel stoves are usually equipped with a regulator to help you manage the amount of fuel used. They're also more efficient than stoves that run on canister fuel, and perform well at high altitudes as well as in cold temperatures.

Certain multi-fuel stoves can be used with wood. This allows you to be more independent, reducing the need to purchase fuel. It is important to note that using a multi-fuel stove with wood could result in more harmful emissions and is not recommended unless you've taken the proper safety precautions in place.

Thermostat Control

A boiler stove is a great option when it comes to multi-fuel stoves for those who want the stove to heat their water and their living space. The boiler stove can heat a tank of water inside the stove, or be connected to an oil or gas central heating system to boost its energy output. These types of stoves can also be utilized in smoke-controlled areas since they can burn a variety of solid fuels.

Modern stoves come with thermostat controls which allow the user to adjust the amount that is burned. This in turn controls how much heat is produced. This feature can help save money by ensuring the maximum amount of heat can be generated from each piece of fuel.

Boiler stoves are able to be used with a range of different fuel types, including peat, wood and smokeless coal. Many multifuel stoves allow users to select between various types of fuels when you are making an fire. This is because the different kinds of fuel require slightly different airflows for proper combustion.

Smokeless coal for example requires combustion air from below and most multi fuel stoves will feature an open or partially open riddling grate to allow air to flow through. This grate needs to be riddled frequently to prevent the accumulation of ash, which could cause the fire die.

All multifuel stoves are able to transfer some of the heat they generate into a domestic water heater, regardless of whether they're boiler stoves or not. The amount of hot water that can be provided by a stove is contingent on the model, however generally speaking, they are capable of powering up to 8 standard-sized radiators. Some models, like the Stovax View 8 are able to achieve this feat with the capacity of 4.9kW for the room and 8.2kW for the boiler. This is enough to power the majority of domestic radiators.

Suitable for Smoke-Controlled Areas

The capability to burn a variety of smokeless fuels makes a multifuel stove a great option for those who live in Smoke Control Areas. You can save time and money by not needing to carry or store logs or briquettes that are not always available. The multi-fuel stoves are also more contemporary than their open fire counterparts and are available in a range of sizes that can be fitted to homes with different designs for interiors.

These stoves are called DEFRA Exempt or approved solid fuel appliances and are tested to ensure that they meet strict emission limits particularly when burning smokeless fuels. These stoves are ideal if you live in a city with a lot of smoke-producing structures. They can reduce the amount of black fumes generated by your heating system.

A DEFRA approved stove can be used with a wide range of solid fuels including anthracite and smokeless briquettes. Certain fuels are not burnable in any way and it is illegal to use them unless you have a certificate of smoke control.

This type stove can be modified to accommodate oil and gas sealed heating systems, or even underfloor heating, based on the model you pick. Depending on the model, they could also be be  linked to solar panels and renewable energy sources.


A multi-fuel boiler stove is usually fitted with an opening in the glass that allows you to see the fire and the flue through which combustion gases are drawn and expelled from the appliance. It will also have an open fire grate that you can place your fuel and the air supply to the flames is controlled via an adjustable slider that is located at the bottom of the stove's door. Some models also have a secondary or tertiary air flow system that introduces the pre-heated air from the secondary or tertiary into the combustion chamber at a height above the fuelbed. This reduces emissions by combusting any hydrocarbons that are not burned in the smoke before it vents upwards into the chimney system.
