This is the second post in a series on DH. The first can be found here.
As I mentioned in my previous post, cost of heat on DH schemes is directly tied to system efficiency. The more efficient the system, the less fuel is needed to meet the heat requirements of the customers. And of course the reverse is also true: lower efficiency means higher cost of heat. This relationship between efficiency and cost is hugely important: it’s real cash, coming from residents to pay their heating bills and from the landlord or ESCO to pay the fuel bill.
In fact, I’d go as far as saying that efficiency is the single most important issue for DH schemes. This post explains why efficiency matters so much.
