How to store heat in a thermal store

Only a serious biomass nerd can get excited about thermal stores. Sadly, I count myself as one of those people. First of all what is a thermal store and what does it do? Essentially it’s a large water tank (usually round) which is well insulated with a series of bosses to connect pipes …
