Altech Massiv Basic

Altech Massiv Basic

The Altech Massiv Basic is a unique, freestanding soapstone wood-burning stove from the Massiv series by Altech. This stove has a robust appearance and features the same heat storage capacity as traditional, solid soapstone stoves. Despite its significant size, the stove does not take up much more floor space than any other conventional wood-burning stove. This makes the Massiv a suitable choice for virtually any house. This makes the Massiv a suitable choice for virtually any house.

Mass of soapstone for optimum heat release

The Massiv features a mass of over 900 kilograms of soapstone. The soapstone ensures a delightful, gradual heat release, which means the stove can release heat for hours after the fire has been extinguished.

It is also possible to enjoy the delightful heat of soapstone for even longer, as the Massiv can be expanded with an extra layer of soapstone. The larger the soapstone mass of a stove, the better its heat storage capacity and the longer the soapstone stove can release heat.

The Massiv is available in different varieties

The Massiv series consists of 2 different models. All models have the same base, but feature different details in their appearance. The Massiv Basic is a sleek soapstone stove that can be expanded with an ash lip and an extra (5th) layer of soapstone (at an added charge).

The Massiv is available in natural soapstone with anthracite cast iron or in uniform black soapstone with black cast iron.
