FAQ - Frequently Asked Questions

Before your purchase

Which wood burning stove should I choose?

There are many things to consider when choosing a wood burning stove. It is really a matter of taste, but also of the possibilities in the room in which you want to install the wood burning stove. You can get an overview of the most important points to consider in our stove selector/guide here. In addition, you can schedule a non-binding meeting with one of our dealers, who can quickly give you an overview of the possibilities in precisely your home. See our dealers here.

Which wood burning stove is best?

This is a hard question to answer. At RAIS, all our stoves and fireplace inserts live up to the strictest environmental and quality requirements. This means that with RAIS you have a wood burning stove that will last for years to come and that you can always get advice, help and guidance to get the most out of your stove.

What does a wood burning stove cost?

The price of RAIS stoves varies significantly depending on the model and accessories you choose (e.g. CleverAir and the like). Contact your nearest dealer for prices.

How large should my wood burning stove be?

As a rule of thumb, a modern stove heats 10 m2 per kilowatt. A 5 kW stove can thus heat up to 50 m2.

What if I want a stove in a summer cottage or a small room?

For a cottage (depending on the size), you can choose between all RAIS models. If the wood burning stove will be in a small room, it is a good idea to choose a stove with a small chamber (for instance RAIS Q-Tee).

What is the difference between a stove and a fireplace insert?

A stove is a free-standing stove, such as the ones you can see here. A fireplace insert is built into a wall, as you see here.

What requirements must the chimney satisfy?

Always check national legislation regarding the requirements your chimney must satisfy. There are different requirements regarding how much can be connected to the same chimney, the height of the connection and the distance to the wall behind the stove. If in doubt, contact your RAIS dealer.

Can I use the wood burning stove as a partition?

Absolutely. Our inserts work well as partitions, particularly Visio 3:1, Visio 2:1 and RAIS 2:1.


Who assembles the stove?

You can do it yourself, or you can have one of our approved dealers to do it for you. Find your nearest dealer here.

Can I set up the wood burning stove myself?

Sure you can. You should follow the installation instructions that come with your product and study the existing relevant national legislation. If in doubt, contact your RAIS dealer.

How do you replace a wood burning stove?

You can do it yourself, or you can contact a dealer who can do it for you.

Can I have a stove if I don't have a chimney?

No, unfortunately not. You must have a functioning chimney in order to install a wood-burning stove.

What is external air?

Some newer houses are so well insulated that it can be difficult to produce enough draught in the chimney. In such cases, you can connect external air, i.e. air introduced from outdoors instead of from the room. We call this system AirSystem, and it can be hooked up to all RAIS stoves.


Why does my wood burning stove smell?

There can be several reasons for odours from your wood burning stove. If it has not been used for some time, it can be charred dust and grime.

Why is my wood burning stove producing smoke/soot?

Smoke in the stove may be caused by insufficient draught in the chimney. Check whether the smoke duct or chimney is blocked. Soot on the outside of the wood burning stove is usually caused if the door is opened while the flames in the stove are still high. Always wait until the fire has died down before opening the door. It can also be because you opened the door too fast. Always open the door gently.

How do I clean my wood burning stove?

Always clean the wood burning stove when it is cold. Clean the outer with a dry or slightly damp cloth.


What firewood/type of wood should I use for my wood burning stove?

You can use almost any kind of wood as firewood. The key thing is that the wood is chopped and dry (drying time approx. one year).

How much firewood should I use?

You will need 3 – 4 large pieces of firewood. But most importantly, you will need plenty of kindling. That allows the fire to catch easier.

How do I ensure optimal firing?

You can see here, how to proceed correctly.

Can I use fuel other than firewood? Briquettes?

You should only burn wood in a RAIS wood-burning stove. There are different coke types and briquettes, but these types of fuel risk having heat values that are higher than wood and you may end up exceeding the maximum effect of the stove. This is called overfiring and can damage the wood burning stove. In case of overfiring, the warranty on a RAIS stove becomes void. Additionally, you should never use paper, cardboard and similar materials as fuel, as it can emit harmful fumes.

I have a small child/infant. How can I secure my stove?

You can place a fireplace screen in front of the stove, so the children do not get too close to the hot stove.

Health and environment

Are wood burning stoves unhealthy/hazardous to the health? How is the indoor climate?

When you use your wood burning stove, you should always open and close the door slowly. This way you avoid fanning the fumes from the stove out into the room and affecting the indoor climate. Moreover, you can add our AirSystem for your wood burning stove (external air supply), so the air to the stove is drawn in from outdoors. This way the wood burning stove doesn't affect the indoor climate in the room.

Are wood-burning stoves CO2 neutral?

Wood-burning stoves are CO2 neutral, as the burnt wood gives off just as much CO2 as it would have done if it had rotted naturally.

Does a wood-burning stove pollute?

All fires pollute in one way or another. However, with a wood-burning stove, the fire is controlled. In other words, a stove pollutes far less than an outdoor bonfire, for instance. RAIS wood burning stoves are subject to strict environmental and quality requirements, and we are constantly working on reducing emissions of particles from our stoves.

I have asthma and/or allergies. Can I have a stove?

For health-related questions, you should always consult your doctor.

I am pregnant. Should I avoid wood-burning stoves?

There is no particular reason to avoid wood-burning stoves when you are pregnant. If in doubt, contact your doctor.

Gas stoves

How does a gas fireplace work?

A gas fireplace works like a closed combustion system with a double chimney. In other words, the fireplace emits fumes from one part of the duct, while the other part draws in combustion air. Thus, the gas fireplace in no way affects the indoor climate in the room.

Can I use my regular chimney?

Gas fireplaces use a different system than traditional wood burning stoves – namely one with two ducts in one. One for cold air that draws air in, and one for hot air that sends it out. But a gas fireplace doesn't require nearly as much chimney as an ordinary wood burning stove.

Does a gas fireplace produce heat?

Yes, it does. In some instances, a gas fireplace can produce more heat than a traditional wood-burning stove. Moreover, it is fast and easy to adjust the heat using the remote control or an app.

How do you supply gas to the stove?

External gas has to be supplied to the stove, either through a gas cylinder (can be concealed on the other side of the wall, for instance) or through installed gas (natural gas).

How do you set the gas fireplace?

It is fast and easy to set the gas fireplace using the accompanying remote control. With it, you can set how much heat you want from the gas fieplace.

Can I get an app for the gas fireplace?

Yes, you can. You simply need to connect a WiFi module and a power adaptor. For safety reasons, the gas fireplace can only be operated from the same network. The app is called "Myfire App" and is available for iOS and Android.
