Last month we replaced a 12 year old oil boiler with a new Grant Vortex condensing boiler for a very good customer who is quite meticulous at keeping records of how much fuel he uses over the year.

Last night he phoned me with the most excellent news that he was now using 39% less fuel per day than he was with his old boiler and is very pleased with the result.

So if you have an old oil boiler and are wondering if it’s worth renewing think again and many thanks to my customer for the positive feedback.
