Which brings me to what I do as well as farming. I have become involved in re selling the Dragon water heaters, and my one a D 8, is often used to explain the advantages of biomass heating. With the Dragon I have also installed a buffer tank to smooth out the collection ,storage and draw back of heat. Further information at their web site, www.dragonheat.co.uk
Part of the storing of heat in the buffer tank is a Swedish valve called a Laddomat 21 charging package, which promotes boundary layering in the buffer tank. I import and sell these products for Termoventiler AB in Ireland.
