| Masonry stoves are domestic wood-burning heating appliances with an internal firebox made of refractory (heat-resistant) fire bricks, and a system of flues within the stove, made from the same material. The entire stove will contain between one and five tonnes of masonry. A kachelofen (German), kakelugn (Swedish) or kakkelovn (Norwegian) is a type of masonry stove. Kachel means tile, so a kachelofen is a tiled stove. Masonry stove is a generic term that includes stoves without tiles. | Masonry stoves are domestic wood-burning heating appliances with an internal firebox made of refractory (heat-resistant) fire bricks, and a system of flues within the stove, made from the same material.

| The Roman hypocaust was a massive stone structure with a large firebox and flues under the floor. The hot masonry radiated heat for public baths, but required slaves to stoke the fire day and night. The masonry stove that we know today began to appear in the 15th and 16th centuries, in central and eastern Europe. In the 17th and 18th centuries, Scandinavian monarchs funded research into better stove designs due to shortages of fuel. Germans, Scandinavians and eastern Europeans took the masonry stove idea to the US, and only now are they beginning to appear in western Europe, notably Spain, the UK and France. | The Roman hypocaust was a massive stone structure with a large firebox and flues under the floor.

| In an ideal situation, a masonry stove should be able to burn 980g of material and leave only 20g of ash from 1kg of wood. Combustible gases don't ignite until they reach around 800°C - easily achievable in a masonry stove. By allowing abundant oxygen into the combustion chamber, masonry stoves can reach a combustion efficiency of 95-98% (a modern, clean-burning wood stove is around 80% efficient, and an old stove maybe 60%). | In an ideal situation, a masonry stove should be able to burn 980g of material and leave only 20g of ash from 1kg of wood.

| If you're going to get a masonry stove installed, you may as well make it work as much as possible. A stove can be tall enough for the top to emerge into a first-floor room, to heat upstairs as well; we've already mentioned hot water; it can also include an oven and a hob for cooking; and the flueways can be diverted to heat an adjacent, very cosy bench. | If you're going to get a masonry stove installed, you may as well make it work as much as possible.
