Ashburton Hospital powers down coal, switches to efficient energy
By local democracy reporter Jonathan Leask:
Coal boilers at Ashburton Hospital were shut down for the final time on Monday, switching to a new $9.4m state-of-the-art energy centre.
Ashburton and rural health site maintenance manager Dan Wilson, who flicked the switch for the last time, said he was happy to shut down the boilers, which had been on the verge of complete failure for years.
There were months when there was a system failure every night, he said.
“It wouldn’t have lasted another winter I believe.”
Health New Zealand - Te Whatu Ora facilities and engineering manager Terry Walker said the project was conceived in 2018 when the boilers were perceived to be on the brink of failure, and Wilson had done a brilliant job keeping them going until now.
Two of the coal boilers have heated Ashburton Hospital for more than 60 years and a third was added in 1985.
Taking their place is a new heat pump system powered by water sourced from aquifers beneath the hospital grounds, which will provide heating and hot water to all buildings on site.
It draws water in from two extraction bores, using a refrigerant cycle to turn the heat into electricity, before returning the water to the ground.
A new diesel boiler has been installed in the energy centre to supply a backup heating source in case of a power outage.
The annual estimated running costs of $215,000 will be 50% lower than the coal boilers, and the changeover reduces the hospital’s carbon emissions by around 2385 tonnes per year, which is akin to taking 840 petrol-driven cars off the road.
Its life span was estimated to be 20-25 years, Walker said.
The $9.4m project was part-funded with $2.4 million from the Government’s state sector decarbonisation fund.
With the boilers now decommissioned, the plans for the future of the coal boiler building were under consideration, Wilson said.
Canterbury rural health general manager Berni Marra also acknowledged Wilson’s efforts for keeping the boilers going, and noted how lucky Ashburton was to be the first hospital in New Zealand to have the ground source heat pumps.
The project was one of 19 coal boiler replacements undertaken by Health NZ since 2020 and was the last Health NZ coal boiler to be replaced in Canterbury, which made it a significant milestone in the decarbonisation programme, Marra said.
Poll: Should we be giving the green light to new mining projects? 💰🌲
The Environmental Protection Authority announced this week that a proposed mine in Central Otago (near Cromwell) is about to enter its fast-track assessment process. A final decision could come within six months, and if it’s approved, construction might start as early as mid-2026.

‘Tis the season to not get scammed ...
As Christmas gift shopping moves increasingly online, scammers are ramping up their activity across the country.
Dunedin’s Investigation Support Unit is seeing more and more people fall victim to scams and other fraudulent activity, particularly on Facebook Marketplace.
There are a few ways to avoid the scams and keep yourself safe doing online trades this holiday season, says Southern District Service Delivery Manager Senior Sergeant Dalton.
🔒 “A good first step when looking to purchase something on Marketplace is to check when the seller’s Facebook profile was created. If it’s very recent, there is a higher risk that they have just created this account for a one-off fake item.”
🔒 Another important step is to make sure the seller’s profile name and bank account name match up. “We’re seeing a lot of scammers claiming their bank account name is different because it belongs to their partner or family member - that’s a huge red flag."
🔒 “When you’re selling, never trust a screenshot anyone sends you showing that payment has been made. Check your own bank account to make sure a payment has gone through."
🔒 “Quite frankly, it’s best for all parties to agree to pay, or be paid, for items in cash and in-person. Ideally in a public place with CCTV coverage."
🔒 "If you’re buying a car, check Carjam.co.nz to see if it’s stolen or if there’s money owed on it.”
A reminder: Suspicious activity can be reported on 105
