Gas Boiler

  • No Storage Problem: Gas is supplied directly to your home with pipes so that you don’t have to worry about the storage of fuel for your boiler.
🔺 Cons
  • Connection Problem: You’ll have to depend on the municipality for the supply of gas if your area doesn’t have a gas supply you can’t have a gas boiler.
  • Maintenance: Installation and maintenance of gas boiler can be expensive as you have to connect it to the main supply line and cost of pipes and labor can be sometimes substantial.
  • Gas Leaks: Carbon Monoxide gas leaks can happen if the connections are not maintained properly. It may result in fire or explosion.


Oil Boiler

✅ Pros
  • Availability: You don’t have to depend on the municipality for the supply of oil; you can buy it from a local vendor and store it without worrying about supply.
  • Clean Energy: Surprise! Oils may not sound like clean energy at first, but, now some companies make oil mixed with biodiesel. Biodiesel blended oil burns much cleaner than the traditional oils.
  • Independence: As the availability of oil mostly depends on you, you don’t have to depend on gas supply or electric supply to heat your home with a boiler. You only need to get it delivered and store it.
🔺 Cons
  • Storage Problem: Though oil boiler gives you freedom, it also gives you the burden of storing the fuel in your premises. You can only store a limited amount of oil and also have to take care of stored fuel, which can be stressful.
  • Delivery: Oil cannot be produced by yourself; you have to be dependent on your local vendor for its supply and delivery. If you run out of fuel in adverse weather, you would not be able to heat your home.
  • Traditional Oil: If your local vendor doesn’t sell biodiesel blended oil, your oil boiler will harm the planet.
