ELCO Heating Solutions has supplied two THISION® L ECO 70kW condensing gas boilers to the headquarters of Curver UK – the international company and European market leader in the production of home and leisure products.

The installation was part of an upgrade to the heating and hot water system at the Redruth-based office facility, with the new THISION® L ECO boilers replacing old and inefficient units. The two new boilers were installed on a wall mounted cascade frame, complete with low loss header, a 100/150 room sealed flue gas system and cascade insulation kit.

The main contractor for the project was Blue Flame (Cornwall) Ltd, with manager Duncan Impey taking the lead. Explaining the refurbishment further, Duncan said: “As commercial heating specialists, we were brought in to design, manage and construct a new heating and hot water system for the offices. Central to the project was replacing the old boilers, which had become unreliable and beyond their economical life.

“We needed to specify two wall mounted units, so after speaking to ELCO, it was agreed that the new THISION® L ECO boilers were the ideal replacements, offering a great balance of efficient performance and simple installation. Overall, the boilers have helped contribute to a really successful job.”

The new THISION® L ECO boiler is available in three outputs from 66kW to 120kW, with each version utilising state-of-the-art design to produce a class-leading unit. A robust stainless steel heat exchanger provides long term performance and efficiency, while a flue non-return valve, built-in modulating pump and on-board cascade controls ensure this new boiler is a practical fit for a wide range of commercial applications.

The new ELCO boilers easily met the requirements of the project, thanks to a unique HEX geometry in the heat exchanger, as well as a flatbed burner, which both provide the boilers with exceptional performance. These two components also allow two THISION® L ECO boilers to operate at maximum efficiency, while keeping NOx and CO emissions extremely low.

Servicing the boilers is also straightforward, thanks to the THISION® L ECO’s specially designed internal configuration, which provides easy access to key components, as well as allowing simple removal of the burner. Furthermore, a ‘Turn-Click Logic’ mechanism ensures no tools are required to replace the boiler’s electrodes.
