Calco Smokeless Coal Mix

I have had a good many people enquiring about Calco because it is such an efficient, reasonably priced, low ash, high heat output fuel, but also because some are worried about it causing damage to stoves.

Calco mix has esentially two main components, as shown in the above photograph, it is a mixture of petro-coke and lignite nuggets. I estimate the mix to be very roughly 3/4 petro-coke to 1/4 lignite nuggets. It is one of the most efficient smokeless coals available, and if it is used correctly, it represents superb value for money.

I have been using Calco mix for two years, and I have seen no perceivable damage in that time. There is a caveat though, Calco is very capable of doing damage if used incorrectly.

Foolish Users Wreck Stoves!

If you were to fill a stove with Calco and just lit it rip, it will redden the stove – and will undoubtedly damage or burn the metal of the stove. This is because petro-coke is a coke – coke is used in smelters to melt iron, cokes are capable of achieving very high temperatures.  However, control the air intake, and thereby the temperature achieved, and you will not have problems.

The purpose of the lignite in the mix is to give a certain amount of ash and a percentage of a fuel with much lower temperature burning characteristics. This modifies the overall burning rate and the ash helps protect the grates and baffles of a stove.

Some stove manufacturers will not guarantee their appliances if Calco is being used, and they are probably justified, because many people have not got a clue about how to properly control the burn in a solid fuel stove.

Calco Great Value BUT use it correctly

I have just checked prices for this winter with our local dealer in County Kerry, Econ Fuels, Monavalley, Tralee tel: 066-4011099. Calco Petrocoke mix is €1 dearer this winter at €15.99 per 40Kg bag, or 3 bags for €45. They also have Lignite Nuggets at €14.99 per 40Kg bag or 3 bags for €43 if you prefer to play safe with your stove. The guys at Econ Fuels say the price increase is due to increased transport costs, which in turn are due to massive price increases and Ireland’s extra taxation on motor fuels.
