WORKING TOGETHER
BWT & LINDLEY'S FARM & MARKET

Running a successful holiday busi­ness in the UK depends on many things and being able to cope with the changing weather is always an issue. So having a heating system you can depend on is vital both for the comfort of your guests and the running costs of the busi­ness. Choosing two Wind­hager biomass boilers in 2014 to power their district heating system, Lind­leys Farm had made a shrewd choice for their holiday cottages, cost effec­tive, effi­cient and green.

In recent years the system had started to suffer from minor leaks and blocked plate heat exchangers (PHE’s). The most likely cause was attrib­uted to an initial poor instal­la­tion and very likely no inhibitor in the system. Regular loss of pres­sure and manu­ally refilling with untreated mains water had height­ened the issues.

The revised heating system now provides an effi­cient district heating system with the added protec­tion of chem­ical free high purity water. This chem­ical free alter­na­tive is able to protect heating systems from scale and corro­sion. It also makes future main­te­nance easier with no chem­ical residue and waste prod­ucts to dispose of. 

In 2024 Wind­hager, aware of the situ­a­tion and the risk to their boilers were consid­ering the instal­la­tion of a Filter Pot (side stream filter and dosing unit) with which to dose the system with fresh chem­ical inhibitors. Adop­tion into the BWT family and a timely CPD presen­ta­tion by BWT’S Chris Hobbs and Wayne Speed, led Oliver Duck­worth and his team to the conclu­sion that BWT’s ‘chem­ical free’ approach to heating protec­tion was a better option and worth eval­u­ating.

With cost, effi­ciency and green creden­tials estab­lished, it was agreed that the system should be drained down and thor­oughly flushed through before refilling with high purity opti­mised water using the BWT MOVE power. The MOVE power has been designed and devel­oped to deliver high volumes of high purity water for the filling and protec­tion of heating systems without chem­i­cals. With the system charged the next step was the instal­la­tion of a BWT AQA Therm HES unit with an SRC-L cartridge, in conjunc­tion with Mikro­fill auto pres­suri­sa­tion unit to provide high purity opti­mised water for when­ever the system calls for a top up.
