1. Design and build custom made heater.
2. Install it.
3. Done! ;)

A year ago my brother did the design and build part of heating element. It has 3 x 3W heating power. Each 3W section has temperature switch to optimize power acc conditions. Below there´s led indicators to show the current status of engaged elements.

Today we finally installed it. Heater looks like that:

It´s powered by front reading lamp section. Reading lamps are 5 + 5W normally. I´ve switched them to LED-s. So total max power consumtion should be no more than 11W. Still less than 1A.

With total thickness less than 3mm the heater fits perfectly under the plastic housing.

Outside there´s no visible signs of upgrade

Inside the only clue about something new is a switch installed to the light panel assembly.

First drive was a success. Now I´m curious to perform some more real life testing. :cool:

-12 degrees outside, windscreen slightly icy inside (residual condensation from yesterday).
After 3km drive to gas station the windscreen looked like that:

Thanks guys!

I think we have the circuit boards and components for at least 2 more heaters. Are you willing to buy the assembly?
I am not the owner of design and I know that a lot of hours were spent to create it. I must check up the price and get back to You in case of interest.

Great work, I think it should be tested on the facelift Astra K as I know that their windscreen moulds for front camera are different.

Yes, buying would be of interest. I also have the option to do the component soldering myself.
My car is Model 2016.

So, a week has passed quick.

Acc possible options the price for assembled heater element is 80€ EXW (Estonia).
I have 2pcs ready assembled heaters and the circuit boards for 2 more.

Heater fits LHD Astra K 2015-2019. 99% possibility that it fits to RHD car as well - it just has not been tested.
Heater has been tested by me in temperature range of +2...-18 degrees. It has succeeded in all test runs.

In case of intrest and possible group purchase of 30pcs I could get the price down by a little.
I enclosed the circuit scheme in case someone is inetrested in soldering job / building their own boards.

For more information You can send me direct message / write into topic.

Thanks for kind words! Lots of time and effort has been put into this :) So far, I´d say it´s totally worth it!
