Customers switching from Anthracite into a manufactured smokeless fuel can benefit from longer firelife and higher heat outputs. The pros and cons are summarised in the table below:
+/- | Attribute | The Differences | What this means | Solution |
- | Ash Level | Ash level is slightly higher, but more importantly the ash is different being much lighter | Lighter Ash, reaches parts of the appliance that heavier more granular Anthracite Ash just cannot get to | Customers will need to adopt a more detailed and thorough cleaning and maintenance schedule to ensure air ways remain clear and performance is maintained |
+ | Fire Lighting | Slightly Easier / Same | Made easier by consistent shape of a CPL Ovoid. | Use plenty or air and kindling, but then experiment to find best solution |
+ | Firelife | Should be longer, better fire. Ash helps increase firelife. | Higher Heat Output and Longer Firelife means that customers will start to use less CPL manufactured fuel, leading to savings in their heating bills | |
+ | Heat Output | Higher - more sustained, with a longer peak | ||
+ | Slumbering | CPL ovoids will slumber & recover well, but need to get set up correctly to work successfully | Advice is to run the fire hard before and after slumbering. Refuel, and then open vents to get the fuel burning for 20-30 minutes depending on the appliance, then close the vents down. Repeat in the morning to recover the fire | |
o | Sulphur | Within legal limits at less than 2%. | Authorised for use in Smokeless Zones |
|
+ | Shape | CPL ovoids are a consistent, uniform shape | Pack together in to a nice tight firebed, helping to increase heat output and firelife | |
- | Smell | CPL Ovoids are made using a Molasses binder | Can cause stronger smell on ignition | This is expected and will go away in a few minutes |
+ | Calorific Value | Calorific Value (CV) of Anthracite can be anywhere from 29,000 to 33,000 CV depending on the seam it comes from. Phurnacite is consistently in region of 32,500 CV | ||
+ | Environment | CPL Ovoids manufactured using up to 15 percent renewable material | Lower net emissions of Green House Gases when burning |
|
+ | Cost | Higher heat & longer firelife mean that over time customers will use less CPL ovoids for same heat output | Better Value for Money & Lower heating bills |
|
2-
8+ | Summary | CPL Ovoids last longer and with a higher heat output than Anthracite, but have slightly higher ash | Customers will notice the differences, some positive, some negative | If prepared to experiment and follow the advice given, customers will end up with a high performing fuel that in the long run will save them money. |
