So how much do system boilers cost?

System boilers are “sealed” central heating system boilers. This type of boiler is energy efficient; it provides excellent hot water pressure and is ideal for larger properties where several people wish to use hot water at the same time. For example, a large house with two or three bathrooms being used at the same time would probably be too much for a combi boiler to supply affectively, therefore, a system boiler would be more appropriate in this case as it can easily provide hot water to several sources simultaneously. 

Typically, a system boiler can be cheaper can than other boiler types to install as many of the component parts or built into the boiler itself. Therefore, there can be less work involved with installation. However, larger systems my require additional modification in which case installation costs will increase. 

Installation costs also very widely dependent on the tradesperson you select to install your new boiler. Obviously, in the UK any gas installation needs to be conducted by a gas safety registered installation engineer. Installation prices can vary tremendously dependent on they tradesperson selected. Some will charge you more than others, some will offer a fixed fee with others an estimate, therefore, it is important to ensure you are being offered a fair price and a professional service – Do not get caught out. 

The cost of installing a system boiler typically starts in the region of £1,500 to £2,000. Obviously, the system cost will depend on the size of the system required and whether a hot water cylinder is also required. Boiler prices start at around £650 rising to in excess of £1,500. It is important to note that the cheapest boilers may not be the most appropriate for your property, so it is prudent to ensure the boiler selected is big enough to cover your needs. 

System boilers take up more space than a combi-boiler but are very economical as they store hot water in water cylinders and a new “A rated” energy efficient boiler will reduce the average heating bill by up to £200 per year. This type of boiler also tends to be very reliable and therefore maintenance costs can be kept to a minimum.

How much does a Condensing Boiler Cost? 

The term “condensing boiler” refers to the method that a condensing boiler uses to heat your water and central heating. There are various types of condensing boiler including combi boilers or heat only boilers. This type of boiler tends to be more efficient than other boiler types As the heat generated by the boiler is also used to heat the water in your home, therefore, there is less heat wasted by the system. 

Typical condensing boiler prices will start at around £500 for a small flat, rising to in excess of £3,000 for very large properties. Our comparison site allows you to calculate the optimum sized boiler your property will need to ensure that all of your heating and hot water needs are met whilst ensuring you achieve the most economically suitable results. 

Prices also vary dramatically based upon the quality of boiler purchased. Boiler manufacturers that are widely regarded as providing the best quality boilers such as Worcester Bosch, Baxi and Potterton tend to be priced slightly higher than other lesser quality brands, however, the superior quality of the product tends to ensure you will experience less issues going forward. 

It can be a false economy to buy a cheaper, the lower quality boiler or a boiler that is perhaps too small for your property. It is a well-known fact that lesser quality boilers do not last as long and experience issues and breakdowns which can be very expensive to repair. If you select a boiler that is too small for your property needs, the boiler tends to be overworked heating a large property resulting in breakdown and boiler failures. We would strongly recommend that you ensure whichever boiler you purchase comes with a suitable warranty to protect you against breakdowns in the future. 

Despite the fact quality boilers cost slightly more, they can cost less to install. Many of the major manufacturers provide training to large numbers of Gas Safe registered fitters. This results in heating engineers becoming more familiar with boilers supplied by the larger manufacturers (many have their favourites). It stands to reason that when providing boiler installation quotes, an engineer would be more comfortable installing a well-known brand, which could be reflected in their quotes. 

Once you have selected the most suitable boiler for your property you will find that typical installation charges vary from £1,400 for a small boiler and £2,200.00 plus for the larger boilers. Once again, we urge caution when selecting your qualified installation engineer as the quality of work and prices can vary tremendously. At Compare My Boiler, we ensure that only highly experienced engineers who are Gas Safe registered to undertake our installations. 

How much do oil boilers cost? 

14 to 15 million homes within the UK are unable to connect to a gas main from the National Grid so these properties are unable to benefit from gas central heating. Fortunately, these properties can benefit from alternative forms of heating such as oil or electric heating systems. A replacement oil boiler provides improved efficiency and cost savings as well as being eco-friendly when compared with older style oil boilers. 

As the marketplace for oil boilers is far smaller than that of gas boilers, there is less choice of products on the market to select from, however, there is still an excellent selection of highly efficient boilers to choose from. 

There are two main options of oil burner, namely oil combi boilers and oil system boilers. All oil boilers operate in a similar way to the more common gas boilers, but instead of burning gas they burn oil in order to heat your hot water and central heating system via a heat exchanger. The hot water can be used on demand or stored in a hot water storage tank until needed. 

Customers with oil boilers will need to organise regular deliveries of oil in order to power the heating and hot water system. There are several suppliers to select from and deliveries can be scheduled well in advance. This can come in handy if you are living in an isolated area and are concerned about transport issues in the event of bad weather. The oil delivered needs to be stored on site in an oil storage tank, which then feeds the oil to the oil boiler to warm your heating and hot water. Therefore, this type of heating system is unlikely to be appropriate for a flat or leasehold property as the storage tanks required can be quite large. 

A replacement oil boiler cost starts at around £950 For a small boiler rising to well over £3,000 for a larger system. It is important to ensure the boiler you select is “up to the task” and that you choose the appropriate size of boiler for your property. It is important that you do not select a boiler that is too small for your property resulting in it being overworked. Likewise, selecting a boiler that is too large for your property will take up additional space and be less economical to run. 

Installation of oil boilers is conducted by a qualified heating engineer and will cost from £750 to £2,000 plus dependant on the type and size of the boiler being purchased.
