Well , the kitchen has now been ripped out and the electrics and plumbing put in place ready.
Rather than keep the existing arrangement of electric water heaters in the bathrooms and a gas heater in the kitchen, we are going to install a solar water heater which will feed the two bathrooms and kitchen via a back up gas water heater. It is a lot of work but it will reduce our electricity consumption from the solar panels and batteries and therefore reduce our carbon footprint. Below left shows the pipes running from the tank, buried in a large pipe, to the house. On the right is Antonio the Fontanero feeding the hot water supply pipe through the wall of the Molino, from where it goes up through a void to the first floor bathroom.
