Our OFTEC engineers recently completed an emergency oil boiler replacement in Blandford Forum, installing a new Grant Vortex Eco Utility 15/21kW oil boiler after an emergency survey identified that the customer’s existing boiler required replacement.
When an oil boiler fails unexpectedly, particularly during colder weather, restoring heating and hot water quickly is a priority. Following our survey, we worked with the homeowner to replace the ageing appliance with a modern, high-efficiency Grant oil boiler, ensuring reliable heating for years to come.

The customer initially contacted us after experiencing problems with their existing oil boiler.
Following an emergency inspection, it became clear that replacing the boiler was the most practical and cost-effective solution. Our engineers arranged the installation promptly to minimise disruption and restore heating and hot water as quickly as possible.
Our OFTEC engineers replaced the old oil boiler with a new Grant Vortex Eco Utility 15/21kW oil boiler, including a new concrete base, flue, oil filter and fire valve. The system was powerflushed and chemically cleaned before the boiler was commissioned, tested and the manufacturer’s warranty registered.
Grant has become one of the UK’s leading manufacturers of oil-fired heating systems, particularly for rural homes that are not connected to the mains gas network.

If your boiler has become unreliable, is expensive to repair, or is no longer operating efficiently, replacing it with a modern oil boiler can often reduce running costs and improve reliability.
Grant oil boilers are known for their efficiency, reliability and suitability for homes without access to mains gas.
A fire valve automatically shuts off the oil supply if excessive temperatures are detected, helping to improve the safety of the heating system.
A chemical clean removes sludge and debris that could otherwise reduce efficiency or damage the new boiler.
This installation includes a 5-year manufacturer’s warranty, subject to the qualifying system protection measures, including a chemical clean and magnetic filter where applicable.
