The problem with district heat schemes in the UK (at least) is they are becoming mandatory for new large housing developments but are 100% unregulated every step of the way. The builders do the cheapest job possible because the efficiency targets they're supposed to hit are never measured or verified post install. And unlike the rest of domestic energy in the UK, pricing is totally unregulated. The residents can (and are) charged high rates because it's impossible for them to change supplier. Any potential savings are undone by these two things. The energy regulator has so far refused to do its job because they supposedly don't want to stifle growth in this new market. It is a good idea but it's been sabotaged by greed.
