Which Boiler Is Best: Gas or Oil?

- in Home Appliances

Boilers have been used for home and commercial central heating for decades. In particular, boiler systems work incredibly well for commercial and public indoor heating. When it is time to replace your boiler system, two of the best options for replacement include either a gas or oil system for your home or business.

Choosing between a gas-fired or oil-fired system can be tricky. However, the decision can be simplified after highlighting the pros and cons of each system. Boilers should generally remain unaltered, but they should be replaced every 20-30 years depending on usage, condition, and a number of other factors. When looking to install a new boiler or replace your current boiler, make sure to understand your needs and requirements to determine which system will work best for you and your needs.

When deciding on a boiler, you should first check its efficiency rating, or Annual Fuel Utilisation Efficiency (AFUE). Most gas-fired boilers have a rating between 89% and 98%, while oil-fired boilers weigh in between 80% and 90%, depending on the model. However, with the higher efficiency comes a higher cost, as gas-fired boiler units tend to be more affordable upon purchase and boiler installation.

Gas Boilers

Gas-fired boilers are more efficient in heating, which means it costs less to run a gas boiler once the unit is initially bought and installed. Gas-fired boilers also require little to no maintenance and run well with little interference. They also tend to be quieter and cleaner as well. On the downside, the units cost more, and you need to be located where gas supply is available. Also, gas boilers provide a less heat per BTU than oil boilers.

Gas boilers are ultimately the best long-term economic option as they have high efficiency, but they are an investment. They require minimal to no maintenance too, but you must have access to a gas supply line.

Oil Boilers

Oil-fired boilers are more often the economic option upon purchase. However, oil-fired boilers tend to be less efficient due to the cost of oil and the need for frequent but simple servicing. Servicing is usually performed due to unavoidable dirt and soot build up. Also, a storage tank is required to run an oil boiler, which means it must be delivered to you, but it is also more convenient if you do not have access to a gas supply.

Oil boilers are the economic option for initial purchase, but prices run higher to fuel and run them. They tend to require simple servicing and cleaning but are convenient for those located where there is no gas supply, including some rural areas.

Ultimately, deciding between an oil-fired or gas-fired boiler is an individual decision based on preference, location, and budget. To better guide your decision to install or replace your boiler, you should outline your budget and make sure to highlight the requirements and specs you need to suit your home or business, which will help you select the best boiler for your needs.
