It's all pretty technical but each upgraded unit uses a hefty 20% less energy.
Since my last update in December, we've been working with Braun (the company that makes the machines we're upgrading) to track down and get in touch with everyone who owns, one of the inefficient old models. Braun itself also runs a number of units and we are following these up to ensure they're all fitted with the carbon-saving heat exchangers.
We have signed a further 140 people to the renal network on our website - more than doubling the number to reach 208 representatives in nearly 90% of renal units.
This means that people are not only sharing question about the heat exchangers project, but many other carbon-saving case studies too. There has been a recent flurry of discussion around how to dispose of concentrate bottles - with an Italian renal nurse finding the network as the only place she could get an answer to her question (and since then about 10 other Italians joining).
Many of the emails and calls we receive start off with enquiries about the energy efficiency of renal units by retrofitting heat exchangers but they usually don't stop there. One example is an email we received from a Cancer Centre keen to reuse grey water which currently goes to waste.
Apart from that, we'll continue to spread the word while helping people install the heat exchangers and assist them in tackling any barriers in the process.
