Question 1

Do Solar Hot Water Heating Systems work in bad weather?

Accepted Answer

Yes, it will work on cloudy days, although not as efficiently as in sunny weather.

Question 2

Will we run out of hot water in bad weather?

Accepted Answer

It is normal practice to leave the electrical or gas backup heater on so that in bad weather the system automatically maintains the hot water. Our solar controllers have a backup heating option, making backup heating fully autonomous .

Question 3

What are the savings when using a Solar Hot Water Heating System?

Accepted Answer

Water heating normally takes between 40 and 60% of the average power bill. Savings depend on the current energy rates, the amount of hot water used and the amount of water your heating. Your HWC can act as a "hot water battery" as energy can be stored in the form of hot water and used over a few days if sized correctly. During the summer months, very little to no power is required for water heating. It's only when we experience prolonged periods of rain or cloudy weather that backup heating is required. Heating your pool and spa with solar can further reduce your power bill.

Question 4

Will a Solar Hot Water Heating System increase the value of my home?

Accepted Answer

Question 5

What size Solar Hot Water Heating System will I need?

Accepted Answer

This depends on the number of people in your household and the size of your hot water cylinder. Our aim is to ensure that your solar system meets the needs of your family.
​

• 1-2 adults with a 135-150 litre hot water cylinder require a 1 standard size (2.00 sqm) panel system.
 • 2-3 adults with a 180-200 litre hot water cylinder require a 1 large size (2.5 sqm) panel system.
 • 3-4 adults with a 220-300 litre hot water cylinder require a 2 standard size panel system.
 • 5-6 adults with a 300-500 litre hot water cylinder require a 2 large size panel system.

Question 6

Can extra panels be added later if our family grows (or if we decide to heat our pool?)

Accepted Answer

Yes. The panels are modular and designed for easy add-ons.

Question 7

Can Solar Hot Water Heating Systems be installed on existing homes?

Accepted Answer

Yes, the system complements both new and existing homes.

Question 8

Is Solar Hot Water Heating mains pressure, or low pressure only?

Accepted Answer

Both.

Question 9

Where will the solar hot water heating panels be put?

Accepted Answer

Preferably on a north-facing roof as close as possible to the hot water cylinder. The second choice is facing the afternoon sun (north-west). The third choice is facing the morning sun (north-east). Never facing south. The panels can tolerate a large variation off north with little loss in efficiency.

Question 10

How long do Solar Hot Water Heating Systems take to install?

Accepted Answer

Normally installations take 1 day.

Question 11

What is so great about your Solar Hot Water Heating Systems?

Accepted Answer

Stylish European design, superior performance, ECO friendly, and can be connected into existing hot water systems.

Question 14

What are the maintenance requirements for Solar Hot Water Heating Systems?

Accepted Answer

Occasional cleaning of the glass cover helps maintain efficiency.

Question 15

How good is solar thermal?

Accepted Answer

In pure efficiency terms, solar-thermal or solar hot water heating panels are over three times more efficient at harvesting energy than solar-electric (PV) panels. This does depend on what you want. If you have a lot of hot water to heat up, this is the way to go. Buildings in New Zealand are exposed annually to 20 or 30 times more energy from the sun than they consume in electricity and gas. New Zealand has a world class solar resource.

Question 16

What are the points of difference from other solar heating systems?

Accepted Answer

• Meets European Certification Standards.
 • Pure copper collector for long life.
 • Latest developments in selective surface technology for performance.
 • No ugly and heavy tank on the roof.
 • We specialise in pumped systems which have been proved to be most efficient.
