EECA (Energy Efficiency and Conservation Authority)

EECA supports and has supported SiloStay in the innovation behind the EnergySilo, as the prototype model would be easily rolled out for similar complexes (rest homes, schools etc) that are required to upgrade their centralised systems in order to comply with more stringent environmental standards.

Pellet Boiler System

Utilising a waste by-product of the New Zealand forest industry, pellet boilers are destined to be a major energy producer in New Zealand’s future.

Currently pelletized wood waste fuels the main pellet boiler which heats three insulated cylinders that feed the potable (drinking) hot water for kitchen and bathroom and provides space heating within each silo.

The boiler is made in Germany, leaders in high tech/low tech centralised boiler systems.


Even the Biolytix waste water system is planet friendly. ‘The BioPod’ harnesses the energy in the waste (including the sewage, toilet paper and food waste) to nourish the worms that break down the waste.

As a guest of SiloStay your waste is hugely appreciated by the many families of friendly Tiger worms. You are welcome to sponsor a worm in the Miss Universe Worm competition which focuses principally in helping to sponsor Tiger worms in underdeveloped worm habitats to sponsor young adolescent worms on Polytech “worm development” courses. Judging is based more on intellect than looks.

LED Lighting

With a minimum life of 50,000 hours, LEDs last five times longer than other forms of lighting.

They are the lighting of tomorrow, in the silos of today. When compared with incandescent lamps (average life of 2,000 hours) the disparity is even more remarkable.

All the LED’s on the boardwalks and external lighting of the silos is equivalent to a few 40W light bulbs.

SiloStay uses some 240v technology for cooktops, fridges and plugs for guests’ appliances.


Insulation is in the form of wool, a renewable resource that sheep for the most part happily share with us humans to enhance our warmth & wellbeing.

It is made from the lesser grade wool from the sheep’s nether regions, and a little from south of the border.

No animals were harmed in keeping silo inhabitants warm & cosy.
