Hi Ellen,
Thanks for your question. Yes, you can visit a home with a heat pump installation through the Green Open Homes, a national network of properties that have undergone energy efficiency changes and are open to the public. You can search and filter for the next event near you on their website: Green Open Homes.
Another option is Nesta’s Visit a Heat Pump service (Visit a Heat Pump), which allows you to contact homes close to you to arrange a visit. Alternatively, you can contact installers directly and ask if they provide live demonstrations. We have a number of heat pump installers on our Professional Directory you can make an enquiry with
Hope that helps! Thanks again for you message
