Ecco Stove ® – Simple masonry heater installation

Masonry heaters are a wonderful product to own and stand very much apart from traditional wood burning stoves in the way they operate. Deciding upon installing a masonry heater can be a big commitment as not only the material cost but also the area it will take up in the property and the labour to build it.

A masonry heater or slow heat release heater such as a Kachelofen (tiled stove) or soapstone heater are made up of either brick, clay, ceramic or other masonry components and are often starting from 1000kg and take between a day and 3 days to build (sometimes longer).

The Ecco Stove ® masonry heater is made of 8-9 pieces and its modular design allows for construction in under an hour (see the assembly video). The size and shape of the Ecco Stove ® also allows it to fit into many conventional brick chimney breast with little modification in many cases and flue connections to the chimney are the same as a conventional stove. As such in most cases the Ecco Stove ® installation can be carried out quickly and simply within a day.

Flue and chimney requirements

One of the most important factors in installing any masonry heater is the flue or chimney. You can have a fantastic looking installation and efficient heater such as the Ecco Stove ® but without a properly functioning chimney your stove will not operate correctly.

Stainless Steel Flexible Liner - for existing chimneys

We always recommend having your chimney lined with a 6" diameter liner with the Ecco Stove ® range as this matches the flue outlet diameter. The diagram above shows how flue liner will look in a cross section of the chimney. The register plate above the Ecco Stove® seals off the chimney and helps deflect more heat into the room or in the Ecco Stoves ® case the home. Typically it is a good idea to insulate around the liner to create a good up draught and reduce cold pockets of air in your chimney.

Having a single diameter all the way up also reduces the chance of turbulence when changing from the initial 6" flue pipe to a larger chimney which can slow down the lighting process and cause smoke blow back in the room. The single diameter also makes sweeping a lot easier as one size brush can be used.

Flexible lining can add from around £800 to the cost of installation but gives the Ecco Stove ® a good engine to work from and easier maintenance of your chimney in the long term so it is worth the investment.

Stainless Steel Twin wall flue system - For properties without a chimney

If you do not have a chimney in your property a stainless steel twin wall system can be installed wither through the property or outside the property depending of your preference and the route it would need to take. Again with the Ecco Stove ® a 6" diameter system would be required which would give an external diameter of the flue system of approximately 8" depending on the manufacturer.

A twin wall system has two tubes with usually 1" of insulation running between them which acts as a fire barrier. This allows the flue to be fitted closer to combustible elements of the property but also stops the gases cooling too quickly and sending smoke from the fire back into the room.

For a two storey property twin wall systems can start from around £2000 - £2500 but this is cheaper than constructing a chimney from scratch and is easy to assemble due to its modular design so the flue and the stove can likely be installed on the same day and provide a very good draught due to the insulation properties inherent in the system.

Pumice Chimney Lining system - For new builds and reconstruction

A pumice chimney lining system is a modular design to be built into an existing chimney or to be built constructed as the chimney is built. This system is a more permanent solution than a stainless steel flexible liner as the pumice is a volcanic rock like material so more durable and due to the materials properties heat will be held in the flue for longer retaining the required heat convection for the Ecco Stove ® or any other wood fired appliance. Usually the pumice liner is back filled around with a material called Leca that will further insulate the flue gases.

Pumice lining system would need to be built in conjunction with a chimney system so would typically be the most costly although would provide the most long term solution.
