St Paul's Collegiate School in Hamilton has come up trumps again at the recent Fieldays Online Innovation Awards.
For example, Longveld's Dairy Hot Water – a gas water heating system – can save a farmer almost 50% of shed water heating costs.
The system quickly heats the water just before it is required, removing the need for multiple water cylinders and dealing to the inconvenience of power shortages, but still providing any amount of hot water 24/7.
The firm's second generation gas system, called Longveld Stack, has all the benefits of gas water heating in a package that also addresses food security, safety and space-saving.
The Stack has a water cylinder and dump tank mounted one over the other in a compact footprint; sizes range from about 1m diameter for a 400L supply to 1.25m diameter for a 1000L supply.
Longveld managing director Pam Roa says the removal of pipework between the cylinder and dump tank, and the ability of the components to be independently rotated, mean the Stack suits any configuration of shed and takes up minimal space.
"Chemical dosing is through a lockable access-way which makes the unit tamper resistant, increasing food security, health and safety, and preventing entry of rodents and birds into the dump tank. The cylinder is fabricated from 2205 stainless which will last the lifetime of your shed."
