Customer Reviews

  Effective heater  Completely solved the fogging problem on my Meade LX. Easy to set up and appears well made. The telephone advice from Harrison Telescopes was very useful with regard to the Heater Tape and the Pegasus V2 Controller and saved me from buying extra unnecessary kit.  (12/03/2019) -


    I have had bad experience with past due heater straps that have frustratingly left horrible visible black marks on my white TMB optical tubes. I had an absolute nightmare cleaning these marks off. However, Ed of Harrison telescope knowing my past problems, introduced me to The Dew Zapper Heater Tapes. Well, all I can say is, what a top quality product. Thank Ed! These Heater Tapes are well made, and have a generous length of moisture resistant leads that Im please to say is massively beneficial for long focal telescopes. Also no more horrible black marks on my telescope tubes this for me just say quality. On a final note Im please to say my new Dew Zapper Heater Tapes are now in full use connected up to my two Pegasus dew systems.   (09/11/2018) James Howes - South East London

DewZapper dew heaters are the high quality solution, with a geniune Nichrome wire heating element embedded in a silicon rubber subtrate, for durability and moisture-resistance. The 22 awg silicon coated wires have a synthetic rubber outer sheath, which remains flexible even in very low temperatures reducing "cable pull" related tracking errors.

An internal neoprene insulator directs heat into the optics so you won't waste any power.
