Great Big Green Week: Trelissick renewable energy tour

The Great Big Green Week is a national celebration of community action tackling climate change and nature loss. Come and take a tour of our renewable energy system and the ground source heating that has transformed Trelissick.

  • Booking not needed
  • Free event (admission applies)

We have had a ground source heating system installed at Trelissick which supplies heating and hot water for Trelissick house, cafe, barn and the second hand bookshop.

This renewable energy system has replaced our oil boilers that have been here for many years, thus reducing our reliance on fossil fuels.

Come and join us on a tour of the outside of the house and parts of the house that rarely get seen to get an understanding of how our new ground source heating has transformed Trelissick and reduced our emissions output.

The tour includes stair access and some steps, so please keep this in mind when planning your visit. Spaces are limited to 10 people per tour on a first come, first served basis.
