Heating Oil Guide

Moving to a new house can be a stressful time and even more so if you are new to oil heating systems.

This heating oil guide is designed to help answer the most common questions on the fundamentals of domestic heating oil, oil tanks and additives.

Firstly, I will give you a bit of background on heating oil and oil heating systems before we move on to the FAQs.

An Introduction to Heating OilFilling a tank

Heating oil is used by roughly 1.5 million homes in England, Scotland and Wales making heating oil the most common alternative to gas.

The main difference between gas and oil is the presence of an oil tank on your premises. And, the fact that you are solely responsible for ensuring your oil level is checked regularly and you don’t run out of fuel.

Commonly, domestic oil-fired heating systems are powered by kerosene, but some do use red diesel. This is always important to check before potentially ordering the wrong fuel.

Be wary that heating oil and red diesel can have different names.

Heating oil is also called:

  • Kerosene
  • Burning oil
  • 28-second heating oil

And, red diesel is also known as:

  • Gas oil
  • 35-second oil
  • Plant diesel
  • Agricultural diesel
  • Cherry oil

Now, on to the FAQs…

What do I need to know before ordering?

Before you order your first lot of heating oil, make sure that you have considered:

  • The capacity of your oil tank and the current oil level – this will help you to decide the quantity of oil you require (minimum is 500L by law).
  • The upcoming weather – If there is a prolonged cold spell forecast then you may want to consider stocking up.
  • Your preferred payment method – Choose how you want to pay for your order.
  • The desired delivery date – The majority of suppliers offer a standard 10 working day delivery with an option for quicker delivery at higher prices.

How can I avoid running out?

One of the simplest ways is setting a regular reminder to go and check your oil level every month/couple of weeks.APollo Oil Tank Meter

Or, for a more hi-tech solution, you can install a tank monitor which keeps track of your oil level and sends real-time updates to a monitor in your home. Some even include a built-in alarm to warn off any thieves.

Despite being highly effective, these can come at a bit of expense so it really depends on your personal preference.

The most popular models include Apollo and Watchman.

How much should I order?

Bear in mind, that the larger the quantity you order the cheaper price per litre. However, consider your current oil level and the capacity of your tank before you decide how much to order.

How do I check my oil level?

The ever-reliable method of dip sticking still remains one of the easiest ways of checking your oil level.

Oil Tank DipstickA dipstick can be fashioned out of something such as a broom handle and then plunged to the bottom of your tank. Remove the dipstick and measure the top of the oil mark against the side of your tank. This will give you an indication of your current oil level. Comparing this mark to the capacity of your tank allows you to estimate the required volume needed to fill it to the brim.

For a more Hi-tech solution, check out electronic gauges. Once installed, these read your oil level and send the information directly to a monitor or a mobile app. Therefore, you get accurate, up to date readings of your remaining fuel. Popular models include Apollo and Watchman.
