Positives | Negatives | Negatives | Negatives | Negatives | Negatives |
A higher calorific value | Produces harmful emissions and residue | Electricity heating has a higher maintenance cost | Higher installation cost | It is a non-renewable resource | Dependent on weather and availability of sunlight |
Does not produce any smoke | Increasing price due to increased demand | Causes dry air in the environment | Expensive running or energy costs | Coal contains maximum CO2 per BTU | Installation is expensive |
Does not have a solid residue | Diesel is cruder and messier | Highly potential to fires | Higher maintenance costs | Severely harmful environmental, social, health and safety impacts | Inefficient for heating |
Does not emit harmful gases on burning | Diesel production requires large farmlands which damages the land | Emits dangerous levels of carbon monoxide | More restricted to boiler usage only | The high cost of transportation | Requires a lot of storage space |
Easy and safer to store than other fuels | Higher contamination during storage | Reduced moisture in the air can cause respiratory disorders | Oil is naturally toxic, releases carbon dioxide | Coal ash is difficult to dispose | Consumes more time for heating |
Low ignition point | Exhaust fumes can seriously harm and even kill people exposed to it | Highly expensive and inefficient | Oil containers are not compact and not easy to access | Coal emissions cause asthma and lung cancer | - |
It has a controllable combustion | - | Electricity comes from fossil fuels like coal and petroleum which is most polluting | Hard to detect leakage, which makes it less safe to use and store | - | - |
It burns at a moderate rate | - | - | - | - | - |
