How We Work

Frequently Asked Questions (FAQs) About New Oil Boiler Installations

An oil boiler is a boiler that uses oil as its fuel. Unlike gas boilers, which get their fuel from the gas mains, oil boilers are connected to a oil tank via a oil line.

Oil boilers are a great option for properties that are not connected to the gas grid. They are highly efficient, and the cost of oil can sometimes be cheaper than gas, depending on market conditions.

Modern oil boilers are designed to be much more environmentally friendly than older models. They are highly efficient, which means they use less fuel and produce fewer emissions.

The duration of a new oil boiler installation can vary depending on the complexity of the job. However, most installations are completed within a day or two.

It is recommended that you have your oil boiler serviced at least once a year to ensure it is operating safely and efficiently. Regular servicing can also help to prevent potential issues from becoming major problems.
