Thanks for the replies.

This is what happened and I added two pieces of 2x5 on the side that was sinking next to the two bent pieces.

Was waiting for my contractor but never turn up. He bought the wood, keep postpone and postpone and postpone and I worry the roof might collapse and so I go up and DIY. Small job like this dont get their attention. then next day he called and said he would sent his man but I already get it done and sweat

add 3 more with bolt n nuts......then can add/ change to bigger size solar next time

This is serious. Had you got any roof expert to inspect the condition overall? The last thing needed is a failed roof due to excessive load.

How far apart are the roof trusses? 2 feet or 4 feet? Under the general area of the heater tank is there any wall on which the roof truss work rests?

4 feet apart.

See picture. I think it is extra weight due to roof tiles now absorbing water.



Anyway, I think it is now ok since I added 2 pieces of 2x5 supporting the 2 bent pieces. The only thing is it cannot go back to its original, just that I dont think it will sink furhter. The 2 2x5 is supported by concrete wall below as you can see from the drawing above.

what is d estimated cost to install a solar panel as opposed to 2-3 units of those instant heaters with water pump?

Why not use the car jack, jack it back to the original place. Than use a wood to support the bend wood side. That can strengthen back the wood weak bend side.

I worry using too much force and instead of forcing the roof up, it might push down the wall and then pushing to my 1st floor floor slab and worry the floor slab cannot take it. My living and dinning areas is large combined with a beam that is directly under the wall and up to the roof. Better be safe than trying to be too smart. These are all unknown so dare not take risks.

You guys may like to explore Edwards solar heater (www.edwards.com.au).

My old house in Taiping ( wettest town in Malaysia ) use it since 1985 and still serve us well till today. There were once more than 8 people staying there. These thing is build like Land Rover Defender, built to last.

With regular cleaning on thr panel (3 years once), it run like a Swiss watch, accurate and never fail.

Trellis, thanks for sharing. Explain regular cleaning on the panel...what does it involve? I suspect the haze may have dampened my collector's performance.

Here's what I mean at post 301 of this thread

Hi Holcyon,


For my Edwards,

A) we just wash the panel with slight dose of dish washing liquid. Please do it either early in the morning or after 7pm when the temperature cools down.
B) do it only once in 3 years ( maybe taiping is not so dusty )


Of course you can call Edwards disti to come to clean it up, cost about myr 300 per session.

Please practice safe precaution all the time if you are doing on your own.

I am moving to my terrace house soon and looking forward to my new Edwards solar heater.

Trellis, thanks for advice. I will call up my supplier if they do the same. Don't plan to walk the roof anytime.

Am looking for some advise on solar water heater in terms of costing, brand and life span. My house is double storey with 3 bathroom and 1 toilet...any sifu introduce..

Read back and you know which to choose.

This one anytime better.. http://www.microsolarsystem.com/

I wonder why the above survey don't have this brand

This 1 put inside, no need poll already. All others can go 1 corner.

Haha.. well some do think otherwise.

Alternative, use Rinnai Gas water heater. Very reliable and cheap operating cost.

I just installed MySolar today. Nobody mention about MySolar ???

Wow! Really that good?
You are suggesting all to use this?

Don't just take my word. Go and read. Than tell us here good or not.

I will! But from googles, seems like the product is not 'really' commercialized. The creator is more of a scientist than an entrepreneur it seems.
Hope to come back with more info!
