Silicone Protection Tape

£6.67 / €7.80

Silicone Protection Tape
Used to cover and protect external insulation.
This black silicone tape is NOT effected by UV light and adds a protective layer to external insulation. The special silicone compound will only bond to itself, requiring no messy glue compounds that could be damaging to high temperature insulation.
The tape is applied by over lapping the joint which then forms an impervious barrier and protects the insulation from both the elements and bird attack.

Because this tape is manufactured from a silicone compound, it can come into contact with hot surfaces like the solar collector.

Width 38.1mm (1½")
Length 3.048Mtrs (10Ft)
Silicone Tape withstands up to 260'C
Remains flexible to -50'C
Can stretch to over 300% (conforms to irregular shapes)
No adhesive (is self bonding)

Product Shopping Lists

To aid our customers with selecting and purchasing the correct parts for their solar project, we have created this easy guide shopping list. It contains some brief descriptions on products in an easy, understandable format.

Collector Sizing

Instructions for use:
Visit the web site of NASA at the web address below & follow the log on process. It's free of charge. Once you have received your log on details, you can visit the site to find out the Solar Insolation in your area. To do this type in your Lon / Lat co-ordinates or follow the interactive map. Once you have completed this, you will be presented with the 10 year average Insolation values. Type these details into the white section above. You then need to type the amount of Hot water you use per day, this is not necessarily the size of your tank, normally 45 to 50 Litres per adult. You now need to enter the temperature rise of the water, This is not the temperature set point you are trying to achieve, you will normally have residual hot water in the tank & the mains temperature can fluctuate by 10°C and is normally approx. 20°C during summer months. As a rule of thumb, a 40°C rise is normally sufficient.

Results: You can then see the amount of hot water produced on a daily bases by each tube for each collector size and the amount of tubes required to achieve your project. In practice if you are between sizes, it's advisable to round up to the next collector size up.

Solar Expansion Vessel Sizing Program

To aid our customers, The Solar Shop released a program to aid in the sizing and selection of the Expansion Tank. Correctly sizing the solar expansion vessel is important, as it will maintain a healthy system operation by absorbing the increase in water volume. Water is not compressible, so when the system heats up and the fluid volume expands, it is necessary to be able to absorb this increased volume.
If in doubt please contact us, we will be happy to help.
