"Active Pipe Freeze"



I recently had a Solar System installed at my house by Supa Nova, Electrical Power& Plumbing.
I found Irwin Hackner and his team at Supa Nova extremely knowledgeable and helpful in giving this advice.
The installation of the system was carried out in an extremely professional an effective way. 
The team found faults in the existing system and they split circuits to obtain maximum electricity savings.
I would gladly recommend Irwin and his team at Supa Nova for similar installations.

Dear Irwin,

Thank you for fixing our geyser so quickly – your team was extremely professional, courteous and I was very 
impressed with their efficiency. 
You’ve proven that no job is too big or too small for your company and I will definitely make use of your services again.

Kind regards,
Gallo Manor



Dear Sirs,

I want to let you know how greatful I am for your help in getting my generator change over switch in and working,

Your staff and service was excellent.

Thank you,

Going Green


Supa Nova is dedicated to finding green solutions to the ever-growing global problems of water purification and power distribution. We believe that everyone has a responsibility to help save our natural resources and we’re proud to offer alternatives to help this essential cause.


You could for example consider installing Solar Electrical Power, Solar Water Heating or Heat Pumps. By installing a heat pump you can reduce the electricity consumption of your geyser by 70%.


Alternatively we can fit a timer to your geyser to regulate the length of time your geyser is switched on - giving you hot water when you need it, but not wasting electricity to stay hot when you don't need it.  And by fitting an insulating blanket to your geyser and hot water supply pipes, Supa Nova can help you to reduce the amount of heat loss, reducing the amount of electricity needed to keep the water hot.


Installing LED light bulbs will also reduce your energy consumption dramatically – you can get the latest in LED lighting technology from us.
