Boilers are available in an array of sizes and power outputs, ensuring there’s a fit for every home. Certain models are designed for homes with multiple water outlets and bathroom facilities.

Potterton Boiler Prices

Standalone Potterton boilers are priced between £635 and £2000, depending on the type and model. 

Boiler type	Price of boiler	Warranty
Combi	£845 to £2000	2- 7 years
Regular	£670 to £2000	2 – 7 years
System	£635 to £1900	1- 2 years

Potterton Boilers Installation Costs

Potterton boiler installation costs can vary significantly, ranging from £500 to £1,000.

The range is influenced by several factors, such as the location, installation complexity, and the number of engineers required.

For instance, a like-for-like boiler swap is generally less expensive than converting to a new type of boiler. This is because the latter often requires additional pipework adjustment and installation of new units.

Complex installations, such as converting to a different boiler type or relocating the boiler within the home, will incur additional costs and disruptions. 

Final installation costs may also include the price of extra materials specific to the property and installation. For instance, components such as:

• System power flush
• Magnetic filter
• New flue pipe
• Thermostatic heat controls

Hence, to ensure the best deal, you want to compare quotes from various professionals.

Potterton Boiler Warranty And Aftercare Services

Potterton’s boiler warranties range from 1 year up to 7 years. However, the standard length is 2 years.

The length of warranty depends on the boiler model and installation service you choose. 

For instance, the Potterton Titanium range has a 7-year warranty, while the Promax range features a 2-year warranty.

These warranties cover parts and labour free of charge in case of a breakdown during the warranty period, offering peace of mind.

To maintain the warranty’s validity, you must ensure that:

• The boiler is installed and serviced annually by a Gas Safe registered heating engineer.
• The boiler is registered within 30 days of installation.

While the price of Potterton boilers may be influenced by the length of the warranty, with longer warranties potentially leading to higher initial costs, the assurance of free parts and labour in case of a breakdown can outweigh the initial cost.

Hence, you should regularly check the manufacturer’s terms and conditions for any updates or special offers associated with the warranty.

Potterton Boiler Reliability And Annual Servicing

The reliability and longevity of a Potterton boiler can be greatly enhanced with regular annual servicing.

Servicing not only ensures safe and efficient operation but also helps prevent hazardous situations like gas leaks, fires, and carbon monoxide poisoning.

It also helps keep energy bills lower by preventing soot buildup and ensuring the smooth and continued running of the boiler. Additionally, performing regular maintenance greatly extends the service life of a boiler, leading to long-term savings for homeowners.

Moreover, early detection of potential issues during service visits can prevent costly repairs and significantly reduce the likelihood of breakdowns.

For maintaining warranty coverage, it is suggested that customers stick to regular annual services, preferably scheduled before the onset of winter.
