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.

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.
