These units can be plumbed into any “existing” conventional domestic or commercial low-or- high pressure water cylinder, or specifically made h/w cylinder with heat exchange coil.

Free inspection and discussion of the working principle behind this technology, including observation of a working solar hot water collector “evacuated tube type” and the principles and features of how the basic solar controller manages to convert solar energy into hot water.

The average PV panel offered to “Joe consumer” on the market today is 15 to 20% efficient in harnessing the available energy from the sun PV panels offered for Industrial purposes, that are financially cost prohibitive for domestic sale are 22% efficient

By comparison, the technology utilized by the “evacuated tube principle”, used in solar hot water collectors is 72% efficient in collecting the available energy from the sun

Available in 20, 25 and 30 tube models

Due to the potential for damage to occur to the evacuated tubes from rough handling by freighting companies, these units are only offered for sale where the buyer is willing to either pick up, or pay transport costs for me to personally deliver to an address within a 300 km of Whangarei, or part way towards an address.

Poll: Do you think NZ should ban social media for youth?

The Team from Neighbourly.co.nz

The Australian Prime Minister has expressed plans to ban social media use for children.

This would make it illegal for under 16-year-olds to have accounts on platforms including TikTok, Instagram, Facebook and X.
Social media platforms would be tasked with ensuring children have no access (under-age children and their parents wouldn’t be penalised for breaching the age limit)
.
Do you think NZ should follow suit? Vote in our poll and share your thoughts below.
