Solar hot water is still the most energy-efficient and cost-effective way to heat water
Powered by the sun’s free energy
Most families now save $110 – $150 per month
($1,300 – $1,800 per year at 2025 power prices)
With electricity prices still climbing, a typical 30 tube system delivers
35–55 % lower hot water bills from day one,
pays for itself in 4–6 years,
and costs $5,500 – $8,500 fully installed.
Add today’s 0–1 % green home loans, a 10 year warranty,
one-day installation, and no building consent required for most homes.
LED lights and insulation help a little, but nothing comes close to the massive,
long-term savings of solar; it’s still the single biggest bill-slasher you can add to your home.

How Does Solar Thermal Water Heating Work?

Free Hot Water at your Disposal
How it actually works
Pretty simple when you break it down.
Sun hits the roof → free hot water appears in your cylinder. That’s the headline, but here’s the cool bit under the hood…
The evacuated tubes (those shiny glass ones) catch sunlight from any angle – even on cloudy days or when the sun’s low. Each tube is basically a super-insulated thermos with a copper heat pipe inside. As soon as the sun touches it, the pipe heats up fast (think boiling jug speed).
That heat shoots straight to the manifold at the top, then gets dumped into the water that’s quietly circulating between your roof and your hot water cylinder.
A tiny pump and our smart controller handle the whole show automatically – it only runs when there’s free heat to grab, so you’re never wasting power.
Set it once, forget it forever. We call it “plug-and-play” because… well, that’s literally all you do.
Sit back, shower long, and watch the power bill shrink. That’s it.
Install to a solar ready cylinder
Preferred option:
Want the most out of your system?
Installing a solar-ready cylinder ensures that.
Our solar ready cylinders have dedicated solar ports for your solar to connect onto and twin elements, one at the base and one mid way. This helps when your system needs a small boost on a cold, rainy day and heats just the top of the cylinder. They also come with special probe sockets to get the most accurate temperature readings.
Retrofit to an existing cylinder
Second option:
Not in a position to install a new cylinder? Then don’t.
It is easy enough to connect right onto your current cylinder. Connections are made through your cylinders cold feed with a special retrofit valve. Your element will be connected to the controller as a backup for rainy days. The Probes will be specially inserted into your cylinder and can still give you a good reading.
No Building Consent Needed for most standard roof-mounted systems
The Financial Objective:
Most investors see any investment of 10% and over as an extremely attractive investment, particularly in the current economic climate. Usually, the higher the returns the higher the risk of the investment. Our Solar Systems have a ‘savings return’ starting at 35% – 55% depending on the water usage and heating arrangement that the Ice Solar System is replacing. This is a no risk and simple investment with extremely high returns for your money.
