Why upgrade to Premium Kerosene?
Upgrading to Glowmax, our exclusive premium heating oil, comes with a range of added benefits for you and your boiler.
We want your boiler to remain in tip-top condition for as long as possible! Our premium kerosene has been specifically developed to optimise the reliability and efficiency of your boiler compared to standard kerosene. Lowering the risk of boiler breakdowns and easing the stress of unexpected boiler repair costs, making it the best choice if you have an older boiler. More than this, Glowmax shows a better burning quality with lower charand deposits build-up during combustion in the boiler*
If you are unsure if your tank system is compatible with premium kerosene, please give us a call on 0345 600 3423 for advice or to arrange an inspection from one of our OFTEC registered engineers.
