Quick facts on oil boilers and their main benefits

For those who are not able to avail of mains gas, an oil-fired heating system may be a viable alternative. If you are planning to replace an old heating system with a new one, you may want to consider one that is oil-fired. But what do you really know about oil boilers, and what are their main benefits? Let’s find out.

The basics on oil-fired boilers

Most households and businesses in the UK are able to make use of mains gas for their hot water and heating needs, but there are still about 4 million locations which run and operate on oil boilers and heating systems. The primary difference between oil-fired boilers and gas boilers is that gas can be delivered via a mains gas line to a property, whilst with an oil-fired system, the oil is transported via truck and then stored on the site in a special tank.

The main benefits of oil boilers

An oil boiler, as mentioned, can be as efficient as a gas boiler, and this is especially true for an oil-fired condensing boiler which offers even more efficiency due to its ability to recycle waste gases from the flue.

Other considerations

If you are thinking of acquiring an oil-fired boiler and heating system, there are some other considerations to think about. One is the supply. Since you’re not on a mains gas line, your supply may run out prior to your getting a new delivery, so you have to be mindful of the remaining supply of oil. Also, these types of boilers will usually regulate the hot water flow rate, which means that it can be slower compared to hot water from a gas boiler.

Your oil-fired boiler will also need annual servicing if you want it to run efficiently, and this would include servicing for the oil tanks. Additionally, you have to think about where to place the storage tank for the oil; this can be difficult if space in your property is an issue.

Answers on efficiency

Many business and homeowners who are still debating whether to use an oil boiler have particular questions regarding its efficiency. Well, the answer is simple: in many cases, oil boilers are every bit as efficient as gas boilers, sometimes even more. But for a really efficient oil-fired system, it is best to make use of room thermostats for better performance, and the boiler and the thermostats should be wired in a special interlock in order to prevent short-cycling if either heating or hot water are not required. Efficiency can also be affected by the tank for hot water; it’s best to have a tank which has a thermostat. It is also best to place TRVs, or thermostatic radiator valves, on radiators for maximum efficiency.
