How Long Do Oil Filled Heaters Last

Oil filled heaters are durable and can last up to 20 years if maintained properly. Also, there are ways to extend their life and save money at the same time.

If you are looking for an affordable way to heat your home, then an oil-filled heater could be the way to go. Oil heaters are inexpensive, easy to install, quiet, safe, and efficient.

They are also very popular because they are energy efficient and can provide warm air within minutes.

How to maintain properly the oil-filled heaters?

The oil-filled heater lifespan will depend on how well you maintain it. The following tips will ensure its longevity.

  • Check your heat pump's air filter

The first thing that needs to be checked is the filter on your heat pump. This will help prevent dirt from entering into the system which would cause it to work less efficiently.

The best place to check this is in the attic where the unit sits. You should see a small hole with a screen over it.

Remove the cover of the box and look inside. There should be two filters: one large and one smaller. If either of them has been clogged or damaged, replace both of them immediately.

You may need to remove some insulation around the area so you have access to the filters. It’s important not to damage any wires when doing this.

Once you get everything out of the way, make sure all connections are secure before re-installing the parts back together.

  • Clean the coils

After replacing the filters, clean the coil fins by spraying water directly onto them.

  • Keep the thermostat set between 60°F - 80°F.

This temperature range ensures optimal performance while keeping costs down.

Use only quality heating oils such as mineral oil, vegetable oil, or kerosene. Avoid using gasoline-based products since they contain harmful additives.

  • Change the oil every year

The oil heater companies will always recommend changing the oil after 1 year. They claim that changing the oil helps prolong the life of the product.

However, many people don't know what kind of oil to use. Some say that synthetic oil works better than regular petroleum oil but others disagree.

It really depends on the type of oil used. For example, mineral oil is recommended for radiators made with cast iron.

On the other hand, vegetable oil is good for those made with copper tubing.

  •  Always clean and check the surface of oil heaters

This is to ensure the safety of your family members who might come near the heater during cleaning. Make sure no debris gets stuck under the tank lid.

Also, avoid touching the metal surfaces of the heater. Instead, wipe off dust and dirt with a soft cloth.

  • Never leave the heater unattended

Make sure that the heater isn't left alone even for a few seconds. Children especially shouldn't play near the heater without adult supervision.

In case someone accidentally knocks against the heater, turn it off immediately. The amounts of heat energy from the heater and the dangers from fumes can easily lead to burns if there is an accident.

  • Don't forget about maintenance!

Oil heaters require proper care and attention just like any other appliance. Follow the manufacturer's recommendations regarding maintenance.

If damaged, the cost can be high because these units usually run at full capacity 24/7.

Which is cheaper to run – an oil-filled radiator or halogen heater?

Halogen heaters and Oil-filled heaters are both very efficient in terms of space usage.

However, halogens tend to consume more electricity compared to oil-filed heaters. This means that halogens would cost less per unit of power consumption.

For instance, a 100-watt halogen light bulb consumes approximately 0.5 watts whereas an equivalent oil-filled lamp uses 2 watts. So, halogen bulbs save up to 50% of the total electrical bill.

If you choose to use a 1.5-kilowatt halogen heater instead of an oil-filled one, then you'll need to pay 0.50 pounds extra each month.

If you have two rooms which require 200 Watts each, this translates into a monthly expense of 1.00 pounds.

So, when choosing whether to go for halogen or oil-filled heaters, consider the amount of money you're willing to spend. 

Which is better – oil-filled heaters or convector heaters?

Oil-filled heaters are great for colder climates, while convector heaters are best for warmer climates. If you live in a cold climate, consider buying a convector heater.

There are energy-efficient oil-filled heaters that you can buy as well. These types of heaters work by circulating hot air around the room rather than heating the entire house.

These heaters also provide additional benefits such as keeping the home cooler during the summer months.

Convectors heaters are not only effective in cooling homes, but they also help reduce humidity levels inside the house. They keep the indoor environment dryer so that mold doesn’t grow.

How much electricity does an oil heater use?

These electrical appliances are efficient with electricity costs. The mid-range wattage of an oil heater that uses electricity, ranges between 150W to 300W.

Gas radiators are considered to be the most popular type of central heating system used today. Gas radiators are widely available throughout Europe and North America.

They are easy to install and maintain. But, they are expensive to operate. A typical gas boiler will cost £1,000 -£2,500 depending on its size.

An oil-filled radiator has many advantages over gas radiators. It's easier to control the temperature because there is no flame involved.

For example, sunlight heats up water molecules in the atmosphere. Then, those heated water particles radiate heat towards the earth.

Is it safe to leave oil heaters overnight?

Oil-filled heaters are much safer than traditional heating systems.
