Private residence receives premium ELCO upgrade
ELCO Heating Solutions has supplied three Thision L Evo 120kW boilers on a cascade frame to Wentworth Place in Surrey.
The 11 bedroom private residence required a powerful and efficient heating and hot water system that could adapt to the changing demands of the property, including a high DHW load and the requirements of an outdoor swimming pool. The refurbishment consisted of replacing six older units, with new, fit-for-purpose ELCO boilers.
After careful analysis of the project, Thision L Evo boilers were specified along with a low loss header and new combined flue arrangement. The boilers’ high turndown ratio and excellent seasonal efficiencies were key contributing factors for their specification, with the units supplying the perfect balance of power and year-round performance.
Part of the success of the project was attributed to the design of the cascade rig and the flue system, which allowed for rapid installation and minimal downtime. To reduce heat losses and optimise efficiency, as well as provide a clean finish to the installation, the Thision L Evo cascade system was supplied with a full set of insulation panels to neatly cover the flow and return tubes, as well as the low loss header.
Alan Hough, regional sales manager for ELCO Heating Solutions, visited the property and discussed the needs with the owner, as well as established the system design in conjunction with the ELCO technical team. From a practical perspective, a key requirement was to replace the boilers swiftly within a working week. This included the removal of the old units, upgrading the flue and system connections, as well as the integration of the new ELCO boilers.
To complete the task, ELCO partnered with South Wales-based commercial heating engineers, Boiler Burner Maintenance (BBM) Ltd. Managing director at BBM, Steve Gooding, explained the installation in more detail: “This was the first time we’d fitted Thision boilers and we were really impressed, especially with the cascade frame and insulation kit. It all came together on site perfectly, which was really important given the time constraints we were under.”
The new boilers also have built-in cascade controls, which feature a clear text display with integrated master-slave cascade functionality. This makes commissioning simple, says BBM managing director Steve Gooding: “We often find that the built-in controls are more suitable than trying to connect to the BMS. So, in this instance, we chose to use them for full cascade control of the three units, with the BMS providing an ‘enable’ to the master. Again, this has worked really well and we’re sure to repeat this approach on future projects.”
Another objective of this installation was to provide a new plant room that reflects the stature of the property, while also being suitable for the demands and highly efficient for years to come. Alan Hough commented: “This property has been constructed to the highest standards, so when it came to the heating plant, there needed to be an equally high attention to detail. For that reason, we recommended Boiler Burner Maintenance as contractors for the project as we’ve worked together before and knew they would deliver an exceptional end result.”
