I have eight inches of oil in my tank, will I run out tonight as it’s very cold?

You should not run out of oil tonight. You may run out depending on the distance from your tank to your burner, the height differential from your tank to the burner and the capacity of your tank. You should contact your local depot for a delivery as quickly as possible.

What time will the driver be with me?

We contact the driver on your behalf and ask for an ETA.

How long is the hose?

The hose is 50 metres long.

I have got a delivery of oil and my heating will not come on, what can I do?

Your system may have an air lock which means that the system has to be bled.

Our drivers will endeavour to do this for you but he may not be able to re-start the heating system as there maybe another issue with your burner. We will then recommend a heating engineer to look at the system for you.

Can the driver bleed my boiler?

Yes. We facilitate this request, where possible.

If we're unable to do bleed your boiler, we will recommend a qualified heating engineer.

Can you recommend someone to bleed my boiler?

How much oil does a standard modern house use a year?

This depends on the efficiency of the boiler and whether it is serviced regularly, which is a must.

If you look after your boiler, it will use approximately €1,300 per year worth of oil.

This figure can be halved if you install a newer condensing boiler.

Can I spread my payments?

Yes, we have our Budget Payment Plan facility allows you to pay a set amount each month.

How can I tell how much oil is in my tank at any time?

The most accurate means of tracking your oil levels is with a dipstick which you dip into the tank.

Alternatively we have a full range a gauges at each of our depots and at our online store.

How long will 500 litres/1000 litres of oil last as I haven’t used oil before and I’m not sure how it works?

The answer is: every house is different!

Every house is of a different size, build quality, insulation quality and most important of all, air temperature preferences differ from one person to another.

However, we have found that our average customer, in an average, in an average year uses 1,300 litres of kerosene per year.

I am moving my tank. Can you pump out the oil that's in it?

Unfortunately due to health and safety legislation we are not authorised to pump out oil. We do however have a panel of subcontractors who can perform this service for you.

What is the Difference Between Kerosene and Heating Oil?

Kerosene is one type of heating oil. The other type of heating oil is called gas oil. Never mix the two. Always put the correct heating oil into your heating oil tank.

What Notifications are Sent When Oil is Running low?

When oil is running low you will receive a notification on the Magnus™ Monitor app. This will indicate that it is either time to top-up or that your tank has suffered a leak/theft.

Do you have spec sheets?

Please download our spec sheets here.

Are heating oil and road diesel the same?

Road diesel is not the same as home heating oil.

Heating oil is either kerosene or green diesel depending on the heating system.

Road diesel is known as white diesel and must be used in diesel vehicles that use the road network with the exception of agricultural machines which can use green diesel.

Green diesel is used in diesel engines that work off road .

What is Red Diesel?

Red diesel no longer exists in Ireland. We changed from red diesel to green diesel many years ago. The difference between green diesel and red diesel is the colour of dye that is put into the fuel.

What is D.E.R.V Fuel?

D.E.R.V or road diesel (auto diesel) is a diesel fuel that is unmarked and used for mechanical propelled vehicles that use the public roads in Ireland.

What is the Difference Between Gas Oil and Diesel?

The difference between diesel (D.E.R.V) and gas oil is that diesel is for road use and gas oil is for off road and marine use.

How Long Does AdBlue Last?

It is supposed to last approximately 18 months if stored in the right conditions.



How long does the Glen Fuel Magnus™ Monitor System take to install?

Using all-weather adhesive it takes between 15-30 minutes to install the Glen Fuels Magnus™ Monitor System on a standard plastic home heating oil tank.

It can take up to 60 minutes to install the Glen Fuels Magnus™ Monitor System on a metal tank as this will require us to drill a hole into the tank.

What Does Glen Fuels Budget Plan Do?

By calculating how much you spend on home heating oil in a year and dividing this figure by 12 months, you allocate a set amount of money each month to cover your annual home heating bill.


How Much Does Glen Fuels Budget Plan Cost?

When you sign up to Glen Fuels Budget Plan, you are required to pay a once-off €300 security downpayment.

The direct debit then calls a minimum of €90 each month (based on the average heating oil household usage of 1,300 litres/annum).

Does Glen Fuels Budget Plan Require a Security Deposit?

Yes, a once-off security downpayment of €300 is required. This helps cover the cost of your first 500 litre order.

When Do I Sign Up to Glen Fuels Budget Plan?

The Glen Fuels Budget Plan officially runs from July 1st – 30th June each year. You can sign up anytime during the year.

You may cancel the Glen Fuels Budget Plan at any stage by advising Glen Fuels and your bank, in writing, of your intention to do so.

You will be required to pay any outstanding debit balance on your account.

What Is the Difference Between Bunded and Single Skinned Oil Tanks?

There are two types of oil storage tanks. 

Single skinned oil tanks have one layer of plastic, in which the oil is stored. Some county councils have banned single skinned tanks. Some insurance companies will not pay out if a single skin tanks leaks. 

A bunded oil tank can be thought of as a tank within a tank, as it has two layers of plastic. This offers double the protection for the oil within your tank, reducing the risk of leaks causing ground or building contamination.


What is the lifespan of an oil tank?

We recommend considering a replacement after 10 years. Depending on the tank's location (exposure to sun and the elements) and how it has been treated by its owners, the tank may have a longer or shorter lifespan. 

We recommend that you get your oil tank rechecked by an OFTEC certified installer once a year for possible signs of rust, pipe clogs or oil inefficiency. This can be carried out in conjunction with your boiler service.

What size oil tank should I buy?

When buying an oil tank, we recommend you consider: how much oil you use each year, how much outdoor space you have, the number of family members, how often you use the heating and immersion each day, etc.

Normally, residential heating oil tanks are sized 900-1,250 litres with an allowance of 500 litres per bedroom is a good point of reference. The average Glen Fuels customer will use 1,300 - 1,500 litres of heating oil per year. 

Oil tanks for commercial or industrial use will require substantially larger capacity.

If you are unsure about the size you need, please contact your local Glen Fuels depot. 

Can I monitor my oil tank remotely?

The Glen Fuels Magnus™ Monitor System is a remote 24/7 oil tank monitor which sends reports to your phone or tablet and to Glen Fuels. 

This system will notify you and Glen Fuels of a sudden drop in the oil level, which might indicate theft or leak. It also notifies you when it is time to top-up the tank.

The Glen Fuels Magnus™ Monitor System is applicable to houses, businesses and farms all over the world. 

How do I protect my oil tank against theft?

To discourage oil theft from your tank:

  • Hide the tank behind a screen (never plant shrubs or ivy to conceal an oil tank)
  • Apply locks to all caps and vents
  • Install the Glen Fuels Magnus™ Monitor System which will send an alert to your phone and to Glen Fuels if there is a sudden drop in the oil level.   
  • If the tank is in a holiday home, keep the oil level low enough and schedule regular small drop top-ups. 

What is on an oil tank installation checklist?

Before installing a new oil tank, consider the following points:

  • Proposed location of the tank should be a level and solid foundation with safe accessibility for the delivery driver.
  • Follow correct installation steps to maintain tank warranty.
  • Remove and dispose of an old oil tank in an environmentally friendly way.

Is an oil tank flame retardant?

Oil and plastics are fire hazards. It is not possible to make oil flame retardant. 

Always keep fire well away from an oil tank. Position the oil tank on a slightly raised area of ground. An oil tank should always be located at least 1.8m from the nearest non-fire rated building or, if not possible, a 30-minute firewall is required, which must extend 0.3m above and beyond both ends of the tank.

How do I maintain and service my oil tank?

As a homeowner, landlord or tenant you are responsible for ensuring the oil tank on your property is fit for purpose. Checks and repairs should be carried out at least once a year. 

We recommend an annual oil tank inspection which looks for rust, damage and cracks, and which ensures all mechanisms and tank gauges are working correctly. If in doubt, please contact an OFTEC certified installer to carry out a professional inspection and service. This can be done at the same time as the annual oil boiler service. 

Oil tanks should be cleaned out every 3-5 years, depending on household size and tank use.

Should I clean my oil tank?

We recommend the oil tank is cleaned out once every 3-5 years, depending on household size and tank use.

This should be done by an OFTEC certified professional who is able to remove and replace oil (unless the tank is empty), dispose of the oil tank contents safely and legally, and bleed the boiler. 

What is a bunded diesel tank?

Bunded (or double walled) is the technical term for a tank within a tank design. The Kingspan Titan bund is designed to catch at least 110% of inner tank contents in case of failure of the inner tank or overspill.

How and where should I store diesel fuel?

The diesel tank should be delivered ready for installation. It should be installed on a concrete levelled base. Electrical connections must be completed according to local regulations by a qualified electrician.
The diesel tank should be positioned at least 10 feet away from a residence, under cover and out of direct sunlight to avoid water pooling on top of tank and evaporation of the product.

Can I store diesel in a plastic container?

Diesel should be stored in a specialist tank designed for storing diesel.

At Glen Fuels we always recommend a bunded diesel storage tank. 


Is it safe to transport diesel, and what are the options?

Under the European Agreement on the International Carriage of Dangerous Goods by Road (ADR), diesel is limited to a maximum transportation limit of up to 1,000 litres. A suitable, sealed container should only be used when transporting diesel.

What size diesel tank do I need?

The size of your fleet size, mileage and industry will determine the correct tank size to service your commercial vehicles.

For assistance, please contact your local Glen Fuels depot as we have been delivering diesel to commercial customers for more than 35 years. 

How often should my diesel tank be serviced?

Diesel tanks should be serviced annually. Consumable parts should be services as soon as you notice wear and tear.
