Heating specialists, Warmflow Engineering Co Ltd, attribute their success and 40 year longevity to 3 key priorities: ‘Quality manufacturing, quality sales support and quality back up service.’
Warmflow manufacture a range of oil-fired combi, regular and system boilers in a variety of output ratings – something it’s essential to get right when looking for a replacement boiler. You’ll also need to consider the efficiency, warranty and the potential cost.
- Output rating: The size of the boiler relates to the output rating. Measured in kilowatts (kW), the output rating reflects the power of the unit and helps to give an idea of the level of demand for heating and hot water the unit will be able to meet.
- Efficiency: For a boiler to reduce your heating bills as much as possible, the boiler needs to be using the fuel effectively. Some boilers are able to convert more fuel into usable energy than others and this is shown as the efficiency rating.
- Warranty: A warranty will see that you’re covered should a fault arise after the installation of your new boiler. All boilers come with a warranty of at least 1 year but up to 12 years is available on some boilers. A longer warranty shows how confident the manufacturer is in the reliability of that particular model.
- Price: Warmflow oil boilers are priced at the higher end with prices starting from around £1,000.
Our Boiler Comparison Tool allows you to compare the key specifications of up to 4 different boilers. Simply hit the ‘add boiler’ symbol to include a boiler as part of your comparison and don’t forget to include your existing boiler.

Warmflow Boiler Warranty
Every boiler manufacturer offers a standard warranty with their boilers which last between 1-10 years. The warranty is your insurance policy and means if a fault develops the manufacturer will resolve it within a specified time frame.

The most important thing to remember is to get your boiler serviced by a qualified engineer every year as failing to do so is likely to invalidate your warranty.

Warmflow Boiler Repair Advice
Even the highest quality boiler can develop faults and problems as they age. Some are minor issues you may be able to handle yourself but most will need an OFTEC registered engineer to diagnose and repair the problem. To find out if there are any common problems associated with this manufacturer you can read our guide to Warmflow Boiler Repairs & Common Warmflow Boiler Problems.
Warmflow Error Codes
Error codes may appear on your boiler’s display; it’s your boiler’s way of telling you that something is wrong. Each manufacturer uses a different coding system to help an engineer to diagnose a fault. In some cases it may be a simple issue such as low pressure which you can adjust yourself but more technical faults will certainly need a professional. We’ve put together a list of error codes for all Warmflow Boilers to help you understand what’s wrong before you contact an engineer.
