I published a series of posts on my blog on the Forever Fuels website, about the real-life inefficiency of the district heating network that supplies heat from the wood pellet boiler to me and my two neighbours.
This has created some controversy. Not everyone is prepared to accept that heat recirculation in summer because of low usage can result in appalling levels of inefficiency. The most recent figures (for May-Aug 2013) indicate that two-thirds of the heat is being lost before it gets to the houses in summer.
This forum topic is for 2 purposes:
- Comments or questions about my heating system and the losses.
- Tell us about your own experiences of district heating efficiency, good or bad. Have you experienced similar losses, or is your system more efficient? If so, how does it achieve that efficiency?
As in all the posts on the Forever Fuels website, I would emphasise that this appears to have nothing to do with the efficiency or otherwise of wood pellet heating. The district heating losses occur regardless of the heat source. If an oil-fired boiler were producing the heat, just as much would be lost in the same network.
The obvious conclusion if I am right is that the Government was mistaken to encourage "community" schemes, and should instead have encouraged distributed heating (i.e. smaller boilers in individual buildings, rather than one larger boiler sharing its output amongst several buildings). As usual, distributed energy is more efficient than centralised energy. But governments never believe it because they always think that big is better.
