Take a walk on the wild wide | Colchester Zoo

Animals, plants and visitors will all be staying toasty and warm at Colchester Zoo this winter thanks to a new 199kW boiler in a Green Heat Module from industry leading biomass experts, Hargassner UK.

Founded in 1963, Colchester Zoo now houses over 260 species and attracts around 850,000 visitors each year, leading to considerable energy costs. To help address this, the zoo chose to have a new Hargassner biomass boiler from Wood Energy installed by Bentley Fire Shop, supplying heat and hot water to a number of animal enclosures including the ever popular Lions and the new Australian Rainbows exhibit, which recreates a tropical rainforest complete with parakeets.

With internal space limited, the Zoo needed a reliable, external solution. This made Wood Energy’s Green Heat Module the ideal choice. The fully containerised unit is pre-packaged off-site and is supported with a Total Warranty covering the coating, structure, insulation and boiler for the entire 20 year payout period of the Renewable Heat Incentive.

The Module incorporates a wood store and was selected with a 199kW wood pellet boiler from Hargassner. The top of the range model features a fully factory-lined combustion chamber, automatic ash level indication and a lambda sensor with fuel quality detection.

Once on site, Hargassner Registered Installers Bentley Fire Stop were able to quickly fit the Green Heat Module to the distribution system via a single flow and return connection. Installation speed was a key consideration as Gordon Bennett, managing director of Bentley Fire Shop explained:

“Colchester Zoo is one of the busiest zoos in the UK and we fitted the unit at the start of the summer holidays. As a result, it was essential that the work was carried out quickly so as to cause the least inconvenience to members of the public and zoo staff. By utilising the Green Heat Module, installation of the equipment is far quicker and reduces the downtime to the customer.

We lifted the Green Heat Module into place with a crane and our fitters worked together with Cadman Cranes to ensure everything ran as smoothly as possible. Hargassner provided us with expert assistance on the sizing and spec and all in all it took just three days from the start of the installation to them commissioning it.”
