150 Liters Non Pressurized SEVEN SS STARS Solar Water Heater
150 Liters Non-Pressurized SEVEN SS STARS Solar Water Heaters are popular high-quality solar water Heaters. They are made to last longer and are highly adaptive to both fresh and borehole water. They come with an inner tank made of stainless steel to work with the rising use of borehole water. It allows water to get in it by pressure but will only leave at the outlet through the convectional flow. To boost pressure at the delivery, a hot-water-compatible pump can be installed to suck hot water.

Cost and Benefits of 150 Liters of Non-Pressurized Solar Water Heater
Reduced energy bills
In summer, it may be possible to
heat all the water you need with solar
energy. In winter, or on cold cloudy
days, solar water heating will meet part
of your hot water needs – you’ll also
need some supplementary heating
from your booster system.
The exact amount you save from solar
water heating will depend on a wide
range of factors including how much
hot water you use, the solar water
heating system you install, and the
quality of the installation.
It’s been estimated that for an average
household, an effective system will:
- provide at least 50 percent* of
annual hot water needs
- cut about 2200kWh from annual
- provide savings of $350–$450
a year (depending on the cost of
your electricity or gas supply).
Because each installation is different,
the installation cost of a solar water
heating system can vary widely. For
systems connected to an existing hot
water tank, the average cost is about
$5,500. For systems that also include
a new tank, the average cost is around
$7,300. Prices could be higher or lower
depending on a range of factors, such
as the size of the system.
In general, it’s more expensive to install
solar water heating in an existing house
then in a new house. This is because,
in an existing house, you sometimes
- add pipes in parts of the house
that are hard to access
- add structural framing in the roof
so it can carry the extra weight
of the solar water heating collectors
and tank – if you choose to have
the tank on your roof.
You may be eligible for a $1,000 grant.

EECA publishes the indicative
performance data for all solar water
heating systems qualifying for the
$1,000 grant. This is a useful way to
compare the performance of systems
eligible for a grant.
If you install solar water heating,
you’re helping to reduce New Zealand’s
dependence on non-renewable energy
sources and you’re helping to cut
greenhouse gas emissions.
Every residential solar water heating
the system installed is estimated to
save, on average, about 1.4 tonnes
of carbon dioxide emissions a year.
