Ever since 1853, Morso have been heating homes in Scandinavia and worldwide. Morso woodheaters have long been recognised for their superior function, style and classic design - reflecting the unique Danish integration of form, function and quality. Morsos name has always been and always will be inextricably linked with cast iron. Solid cast iron is the traditional material used in constructing wood heaters. It has a unique ability to store heat and release it to its surroundings long after the fire has gone out. Top quality Morso cast iron is resistant to thermal stress and retains its shape so the heater remains airtight but beware of cheaper imitations because cheap cast can cause problems.
