With more than 40 years of experience in manufacturing condensing and non-condensing oil-fire heating solutions, we are proud to be a British brand, manufacturing our products in the heart of Shropshire. A strong commitment to research and development ensures our products have high efficiencies and low emissions, meaning the Mistral range of oil-fired boilers is environmentally friendly and economical to run. We offer one of the most advanced and comprehensive ranges of condensing and non-condensing oil fired appliances in the UK.
Mistral has a network of installers which we can call upon to fit and service your boiler. The boiler must be installed by a suitably qualified person, such as an Oftec approved, or similar, engineer, and paperwork, specifically a CD10 installation document completed. Alternatively, the installation must be approved by Building Control. Prior to operation, the boiler should be commissioned again by a suitably qualified engineer and the CD11 completed. All work must be completed in accordance with the boiler installation manual and comply with all relevant standards and codes of practice.
If your boiler is more than 15 years old, then its efficiency is probably compromised. It may not even have a central waterway, it may have poor insulation and its large baffles (which slow hot gases down to allow a greater transfer of heat to water) may be distorted. The distortion allows the gases to run up the side of the heat exchanger as opposed to following the path of the baffle and the result is a boiler, running at between 60% to 70% efficiency. What may have started life as an efficient boiler is now costing you money.
Every time your burner initially fires, it creates very minute particles of soot, which can cling to the internal sides of the heat exchanger and this can gradually build up over a period of time. If left, it can get to a stage where more and more particles are attracted to this area and this can have an adverse affect on the operation of the boiler. Over this period, there is also the throughput of fuel, which gradually wears the nozzle hole larger, allowing more fuel to pass through and this can change the combustion settings.
