Roll-up stations are recommended for larger swimming pools, so that when the pool is in use, the thermal cover can be rolled up and stored neatly at one end of the pool. PowerPlastics’ thermal covers are available in blue and black and can be manufactured to suit all sizes of swimming pool.

Save Energy to Save Money and Save Your Environment
By Maya Aberman who tells you how and why you should try to save energy. Please note that the figures have increased substantially since this article was written, however the concept of saving energy to help save the environment remains the same.
“In 2018, the average annual electricity consumption for a U.S. residential utility customer was 10,972 kilowatt hours (kWh), an average of about 914 kWh per month. Tennessee had the highest annual electricity consumption at 15,394 kWh per residential customer, and Hawaii had the lowest at 6,213 kWh per residential customer” U.S. Energy Information Administration”
Save energy to save money
How much does the average electric bill cost? The average monthly electricity bill in the US is $110.76.
Typical mid-income households spend R170 to R300 in South Africa on electricity every month (Note these are 2009 figures) using between 500 and 800 units or kilowatt-hours (kWh). Most households could easily save 20–30 percent of this.
Save energy to save water
Power stations use two liters of water for every unit of electricity (kWh) generated.
Save energy to reduce ‘greenhouse’ gas emissions
In South Africa electricity is generated from coal, which produces carbon dioxide (CO2) when burnt (about 1.1kg per 1kWh used). This is the main contributor to global warming, which is expected to have catastrophic impacts. Fuel combustion in cars is also responsible for substantial CO2 emissions (about 0.3kg CO2 per every 1km driven).
How Can You Save Energy – Here Are 6 Ways To Save
1-Save energy to reduce air pollution
Air pollution is caused by car fumes and by burning coal to generate electricity.
2-Buy a pool cover and install a pool-pump time switch
3-Install solar water heating
Solar water heating methods can be used to heat both your pool and tap water. This uses a renewable source of energy and will pay back in electricity-saving over a just few years. If you are building a new house or pool, it is a sound economic choice as the estimated savings are anything from 20–40 percent of the total electricity bill (saving depends on hot water use patterns).
4-Insulate your ceiling
It is estimated that you can save half your electricity bill by insulating you ceiling.
5 – Use compact fluorescent light bulbs
These light bulbs last much longer and use a quarter of the electricity for the same light output as a ‘normal’ light bulb. Also, each compact fluorescent installed saves about 500 kg of CO2 emissions over its lifetime, by using less electricity!
When designing a house:
- make the best use of natural light by including north-facing windows and skylights
- incorporate energy-saving lighting (LEDs)
- design roof overhangs to keep summer sun out but let winter sun in
- install ceilings wherever possible as it is difficult to warm up a double-volume house
- use thermally efficient building materials and insulate your walls and floors well
