The InisMor Mark 2 is the largest boiler stove that Inis Stoves produce and it is designed to satisfy the most demanding of central heating applications.

As the price of home heating oil and gas continue to rise the InisMor MK 2 is an excellent cost effective method of delivering sustainable, dependable heat all year round and when fuelled with wood can deliver low carbon heating.

As with the InisOirr MK 2 and InisMeain MK 2, the InisMor MK 2 has a unique boiler and firebox arrangement that greatly improves both the stove efficiency and ease of use for the customer.

Fuel is burned in a very high temperature firebox that liberates a large percentage of the possible energy within the fuel before passing the gases from combustion through a highly efficient heat exchanger that quickly heats the water within the boiler. This system is much cleaner and more efficient than all other typical boiler designs that drastically reduce combustion efficiencies by depriving the fire of heat too early in the combustion process.

Like all Inis Stoves models, all the combustion air, primary, secondary, tertiary and air wash is guided through long passageways within the stove gaining heat along the way that greatly increases combustion efficiency and temperatures within the firebox.

It has a very large firebox capacity to facilitate longer burn times and can take wood logs of over 700mm in length. The multi-fuel grate is composed of individual riddler bars that can be used in two different positions to facilitate proper combustion of wood, peat and solid fuels.

The InisMor MK 2 has a nominal boiler output of over 18.5kw and if needed can easily deliver 21.5kw by increasing the burn rate. This stove will easily heat 18 standard radiators along with your domestic hot water and can also be used to heat under-floor heating.

The stove is external air ready with the use of a bolt on manifold and our cool touch handles, made of Walnut, allow for safe and easy use.

Convection Air System “More Heat Less Fuel”

All Inis stoves include a convection system, cool air from within the room is drawn into the convection chamber, the air is heated as it rises within the stove which then flows out into the room. The hot air rising draws in more cool air setting up a continuous flow maintaining added heating efficiency.
