>One couple have created an eco-friendly home with a special plumbing system in addition to insulation, it has been reported.
According to the Daily Telegraph, Zoe and Tim Bawtree have built in many energy-saving features into their home.
A ground source heat pump was installed by the couple, who had to drill 56 metres below the house so that a liquid named glycol could be forced down the pipe then back up to the surface – a process which transforms the fluid into a good material for heating their property.
“Whereas a fridge is hot at the core and cold on the outside, the pumped-up glycol is cold at the core and hot on the outside,” Mr Bawtree explained to the newspaper.
“Basically, it provides us with all the hot water and heating we need.”
