Andrew Millward of Home Comfort Assured Slashes Thai Embassy's Heating Costs!

Home Comfort Assured's Andrew Millward, in collaboration with Boilertrust, lead an innovative heating revamp at the Thai Embassy, deploying the advanced Viessmann Vitodens 200-W gas condensing boiler. This selection reflects Millward's commitment to efficiency and tailored solutions for historic properties, which often cannot undergo extensive renovations.

The project, completed in a mere four days, maintained the original pipework to circumvent any potential issues, while adapting the system to function flawlessly across multiple floors. Despite the inherent complexities, including integration with existing boiler controls, Andrew's strategic planning and Boilertrust's execution ensured the property was ready for a significant event immediately following the upgrade.
