In 2016, the heat sector finally recognised the importance of performance data. Helped by companies like Guru, heat network operators began to obtain energy performance data from their networks.

The data sent shockwaves through the industry as many realised that their networks are not performing anything like what was promised, largely due to shortcomings in design and commissioning.

Using this information, the operators of these poorly performing networks could finally attach precise numbers to their long-held suspicions: that losses are high, that heat costs too much and that service can be unreliable. Of course, customers on bad networks already knew this from their own experiences of high bills, cooking corridors and intermittent heating and hot water.

As this awakening gathers pace, a key trend for 2017 will be the move towards quantified performance. Armed with clear requirements, clients will be more specific about what they want, and use measurement and verification to ensure they get it. ESCOs, having had their fingers burnt, will no longer be content to sample the performance on a limited number of dwellings before adopting a new network. Instead they will use performance data to verify that 100% of equipment in homes has been properly commissioned. In short, networks won’t be allowed to go into operation until they work as intended.

This change in approach will have huge implications for the industry.

What... is the efficiency of your district heat network?

What… is the efficiency of your district heat network?

In order for district heating (DH) to fulfil its potential and deliver wide-scale decarbonisation of heat in the UK, it must demonstrate three things:

  • Efficiency: DH networks must transport heat energy from source to customer with low losses.
  • Low carbon emissions: using DH must result in demonstrably lower emission by connecting customers to sources of low-carbon heat.
  • Value for customers:  heat customers must have the means to ensure they’re getting value for their money.

So how are we doing? And what progress have we made in meeting these three challenges so far?

This is the sixth post in a series on district heating. Here’s where to find  1, 2, 3, 4 and 5.

We’ve looked at how district heating (DH) can go wrong. Now let’s look at ways to help make sure it goes right. First: design.
