The Challenge
PBHS (Paul Batchelor Heating Services) was contacted by Mr. Hewitt in Bicester, who had been relying on a 35-year-old oil boiler. While PBHS had successfully serviced the boiler each year, its inefficiency and increasing running costs made an upgrade the best solution.


The Solution
PBHS recommended and installed a Grant Vortex external condensing boiler, a highly efficient system designed to reduce oil consumption and provide long-term savings.
Installation Details:
- External Boiler Setup: The new Vortex boiler was installed outside, freeing up indoor space while improving efficiency.
- Pipework Re-routing & Insulation: PBHS carefully routed insulated pipework from the external unit to connect seamlessly with the existing internal system, ensuring optimal heat retention.
- TRV Installation: Thermostatic radiator valves (TRVs) were fitted to most radiators, ensuring compliance with modern building regulations and providing better temperature control.
- Hive Thermostat Integration: To enhance convenience, PBHS integrated the new system with a Hive smart thermostat, enabling remote temperature control via a smartphone app.


The Results
Mr. Hewitt now benefits from a modern, energy-efficient heating system that not only reduces oil usage but also provides greater comfort and control. The addition of smart technology allows for precision heating management, further enhancing efficiency and cost-effectiveness.
PBHS is proud to support homeowners with expert oil boiler upgrades, ensuring warmth, reliability, and energy savings for years to come.
