Starnge it uses so much Anthracite. That should generate some serious heat.
I also find odd about these products , is their high content of PET coke.
My stove manual warns against high content PET coke products as below.
Maybe I'm not intrepreting this correctly.
6. FUEL GUIDELINES
This Boru Stove is fitted with a multi-fuel grate, which means that fuels such as; seasoned
wood, peat (both with a moisture content of less than 20%) and peat briquettes. Coal can
be used in moderation. But NEVER burn coal as a primary fuel.
DO NOT use fuels with a high calorific value, petroleum coke content and/or petroleum
Petroleum coke has a very high carbon content and is virtually ash free. Ash plays an
important role when fuel burns as it helps to modify the combustion process e.g. the fire
bed temperature forms an insulating layer at the base of the fire to protect the grate from
direct contact with the burning fuel. With such low ash content in petroleum coke the fuel
tends to burn at a higher temperature than mineral fuels. The components of solid fuel
burning appliances are not generally designed to cope with the intensity of the heat that is
generated by the burning of petroleum coke based fuels. High petroleum coke products
are not as strong as approved fuels and are very prone to splitting causing hot embers to
be ejected from the stove or causing a second burn in the ash pan, this could lead to an
unsafe condition. High petroleum coke products can produce excessive soot deposits
because of incomplete combustion due to high moisture, leading to a risk of fire in the
chimney or liners. Burning petroleum based fuels will push your stove beyond it’s design
capability. This will over fire your stove and void your extended warranty.
I was looking at the link to the make up of these , and one thing it tells me is that none of the round ovids are manufactured in Northern Ireland . So I wonder who makes the CW ones ?
