Tilba Tilba Geothermal Hydronic Heating

Project Details

The Tilba Tilba Project involved the intricate retrofit of a geothermal hydronic heating system within a property that combines the elegance of a French chateau with the charm of an English manor, situated in the picturesque hills of Tilba Tilba. This project required meticulous planning and execution to preserve the architectural integrity of this stunning home while integrating a state-of-the-art heating solution.

Key Challenges


Ensuring the new system blended seamlessly with the building’s historical aesthetics was paramount. Every aspect of the retrofit was designed to maintain the visual & structural integrity of the property.


Installing the necessary pipework presented significant challenges due to the building's existing structure & the need to conceal modern mechanical components without altering the home's character.


The installation of the ground collector system was particularly challenging. Located on the side of a hill, the site experienced unprecedented rainfall & flooding, complicating excavation & installation efforts.

System Details


The system is powered by two Stiebel Eltron WPEI 15H ground source heat pumps. These units are renowned for their efficiency and reliability, providing not only heating but also domestic hot water and pool heating.


The collector system comprises 2400 metres of piping, meticulously laid out and connected to a central manifold. This configuration ensures optimal heat exchange and system efficiency.


The installation process involved extensive excavation under adverse weather conditions, highlighting the resilience and expertise of the installation team.

The Tilba Tilba Project stands as a testament to the ability to marry modern technology with historical elegance.

    Client Testimonials

    "John & Declan have run a fantastic service at Everwarm. My wife & I purchased a new house with an already heated slab which has never been used, but the builder hammered a star picket through a pipe which deactivated the whole system. John came out almost immediately & took one look at the system & immediately knew the problem. I don’t think you could find any company who could offer such immediate service & expertise. Congratulations John!"

    "John from Everwarm took on a complex job in installing our geothermal system in a very tricky house. His task was complicated by having to survey a previous installation of hydronics that was left unconnected & buried in the building. He did an excellent job & we now have a state of the art heating & hot water system that is so efficient & economical. John’s attention & commitment is second to none."
