The Boru 400F With AshClear System

Boru 400F AshClear System solving the problem of ashThe Boru 400F AshClear, our first Boru stove to implement the exclusive new AshClear System. The Boru 400F also eliminates the need for an ash-pan, therefore there is less work and mess when it comes to dealing with the ash from your stove.

In addition to the impressive 7.1kW output, the Boru 400F also includes as standard, Airwash and C02 Burn Technology. The easy to use Airwash makes sure that you have clear glass to enjoy the ambience created by the natural flames, while the C02 Burn Technology will ensure a full and clean burn due to the introduction of extra oxygen into the firebox after the initial combustion. As well as the offer of an extended 5 year warranty, the Boru 400F has a lot to offer.

A hassle free, simple design that works with most standard ash vacuums, as a result, the AshClear System promises to make the problem of ash a thing of the past. Depending on the fuel being used, the AshClear System has the capacity to store up to 3 weeks of ash. Due to the variable amount of ash produced by different fuels, depending on the fuel used, there may be a need to vacuum the system more regularly.

The AshClear System collects the ash from your stove, and then using any standard ash vacuum, you simply connect the vacuum to the ash collector and vacuum out the ash. Due to the collection system being designed to work directly with almost any ash vacuum, as a result, there is no need for an ash pan. Consequently there are no ash clouds and mess when it is removed. It couldn’t be easier. With a great looking design and first class build quality; that you can expect from every Boru stove, the Boru 400F is probably Boru Stoves finest stove yet.

Buying A Stove?

Boru Stoves keeping you warm.With the first real cold snap of the winter arriving this month we thought that we would put together a quick guide to buying a stove.

Buying a stove makes a whole lot of sense in today’s world of rising fuel prices, carbon footprints and BER energy ratings. Making sure you make the right choice can be a problem, with so many different stoves on the market and a whole new vocabulary to learn Boru Stoves want to make sure you have all the facts you need to make the right choice.

Stoves come in all shapes and sizes and one of the first questions you should ask yourself is, ‘What do I want my stove to do?’ Is it just for heating a single room, or do you also want to heat water and run radiators from your stove? Below are listed some of the most common terms you will hear when it comes to stoves, and we hope this will help you when it comes to buying a stove.

Output (kWs)

Each stove’s output is measured in kilowatts (kWs). This gives us an indication of the maximum heat output that the stove can achieve. Depending on the size of the space you want to heat, or the size of space plus the number of radiators. You will need to choose the stove with the correct output. Stoves that also heat hot water will have their output divided into two separate output figures, one for the amount of heat given to the room the stove is in and the other is the output or amount of heat given over to heating the hot water and radiators.

So for example, a Chieftain Insert Boiler Stove would give 15kw to heating water and 2kw to heating the room. A Boru 400i (that does not have a boiler), would give it’s whole 7kw output to heating the room. We have a handy heat calculator below that can help you work out the correct output for your room size.

Heat Output Calculator

Simply key in your room measurements, and press "Calculate" to find the heat output required to adequately heat your room.

0kW of heat output required

Note: For optimal output, please use fuel that has a moisture content of 20% or below.

BTU (British Thermal Unit)

This is a traditional unit of energy used to measure power. A BTU is the amount of energy used to heat one pound of water by one degree fahrenheit. This is a very commonly used unit to measure energy content of fuels and the output of heating appliances.

Boiler Stoves

A Carraig Mor Boiler Stove

Boiler stoves are stoves that come with a boiler included, such as the Carraig Mor range. The boiler is used to heat hot water that can then be used in the home and to heat radiators. The size and number of radiators will affect the size and output of stove that you will need. Stoves with a boiler included are often called ‘Wet Stoves’. It is not recommended to run a boiler stove without a water connection, some people think to connect the water at a later stage or perhaps pick up a second hand boiler that is not suited to their needs. Running a boiler stove dry is very dangerous and should never happen.

Dry Stoves

A Carraig Beag Dry Stove

The dry stove refers to a stove that does not have a boiler. These stoves are usually used to provide warmth to a single room or space. They are not suitable for heating radiators or water, this means that they do not need a water supply, ideal in certain situations. 20% of the heat from a dry stove is radiated out from the glass panel on the front of the stove, similar to the way a traditional open fire would radiate heat to a room. The remaining 80% is dispersed into the room by a hot air fan at the top of the stove. The Carrig Beag is an excellent dry stove.

Insert Stove

A Boru 600i Insert Stove

An insert stove is a stove that will be recessed, or sit back into an opening, usually under a chimney or a flue. Insert stoves can come with or without boilers depending on the model and are excellent when you desire a less intrusive appliance in your environment, or if you have a smaller room where space is at a premium. Insert stoves can vary from being quiet traditional like the Fiachra insert stove, to the more contempory and very stylish Boru 600i insert stove that is available with or without a boilder.

Freestanding Stove

A freestanding stove is just that. It is capable of standing on it’s own in the middle of a room, or being placed against a wall protruding into a room or space. Freestanding stoves can come with or without boilers depending on the model, and some freestanding stoves can also be used to cook on.


To ensure that you can enjoy the visual appeal of an open fire with your stove, we have an Airwash system. Airwash is the preheating of air and the funnelling of that air down the front of the glass. This ensures a clear view of the fire.

Central Air Intake

Central Air Intake is using air from outside the dwelling to draught the stove. It means that when you are using your stove there is no energy taken from the room the stove is in so therefore the stove is even more efficient. It is worth noting that Central Air Intake cannot be added on it must be factory fitted at time of order. Central Air Intake is suitable for airtight houses and works with Heat Recovery Systems.

Operating Efficiency

The biggest difference you will see between a stove and an open fire is the efficiency. An open fire usually has an efficiency rating of between 10 and 30%, most solid fuel stoves have an efficiency rating of between 65-80%. The Croi Beag has an efficiency rating of 83.2% so be sure to check the individual ratings.

After Sales Service

A well maintained stove can give you many years of excellent service but at some point it will require replacement parts. Boru Stoves manufacture all our stoves at our factory in Tipperary, we custom build individual parts for each stove. You can rest easy, safe in the knowledge that we are not sourcing parts from a factory halfway around the world that might not be there in six months time. We also offer a six year extended warranty on boiler stoves and a five year extended warranty on dry stoves.

I hope this guide will help anyone who has been thinking about getting a stove by giving a brief overview of the main things to keep in mind. You can contact us with any questions you might have, or find a Boru retailer close to you, and remember, all Boru Stoves are 100% made at our factory here in Thurles, why not check out our video of the Boru factory in action.
