Not really. About 9-11kw per day with one Ac 1.5hp switch on i hours daily.

You need to calculate in monthly because first 200kw is subsidized. Average around 85 in the hot day. Rainy day I when I don't use Ac much is around 65+

Same as solar or gas

Forgot already, is almost 3 years. I got it in super ceramic.

Depend how strong your glass surface are. Do note not all glass are make equal, especially cheap china glass very easy scratch. Below method may scratch some glass especially china cheap glass.

- You can try use 3m scotch scrub with vinegar to rub.
- use very fine sand paper minimal #2000 and soak in water
- toothpaste + cloth and rub.

If unsure, try small area at corner.

Let it growth till entire strip become dark brown

Is either rubber, silicon to hold the glass else it will break. The neutral silicon will (as claim) will not growth fungus.

Having glass door / sliding door require maintenance. Earlier I having another issue with my sliding glass door, the roller keep breaking (crack) think due to the weight of the glass door, and change twice (under warranty), now that is over the manufacture (solid glass) ask me to change the railing to a better design, Of course with some fees. RM 350. Hope this fix the problem. If not I will ditch the mid range sliding door and go for a thick and heavy duty sliding door, of course double to triple the price

Nice things always expensive to maintain lo.

Vinegar don't always work.
