The Challenge

Environmentally friendly system

Located in Crawley, West Sussex, Buchan Country Park is one of the country’s most celebrated green spaces, having been awarded the Green Flag Award every year for the past five years.

West Sussex county Council required an environmentally friendly system to heat and provide hot water to the centre – replacing the existing LPG boilers as well as the electric heaters, water heaters and log burning stoves in two pre-1900s park ranger cottages.  


This was viewed as a great opportunity to install a renewable heating system that would provide a more comfortable environment for guests, further enhance sustainability credentials and saving on energy costs.

The Requirements

Peace and Tranquillity

Combining exceptional efficiency with reliable hot water production and renewable heat provision throughout the year, Ecodan offers class leading low noise operation. The quiet operating noise is maintained in all modes of operation and all ambient conditions, ensuring that the peace and tranquillity of Buchan Country Park remains unbroken.




The Solution

The right Ecodan for the job

With no gas supply to the park, three Ecodan QUHZ 4kW air source heat pumps were considered the ideal solution for the park and were therefore installed.

Adapts to your demand

The efficient system comes with energy monitoring as standard, allowing the owners to keep a close eye on energy usage in the Countryside Centre and providing them with an opportunity to make changes based on patterns of use. With integrated thermal store allowing for a high output of hot water on demand, without the need to pasteurise the water.
