I guess monier gets a factory to OEM for them. From the design and spec, i suspect summer OEM for them as their spec looks similar.

Just compared the spec and you would b able to tell which is a better solar. Usually, we will look at
1) Tank Capacity
2) Number of Copper riser tubes
3) Tank Material

I have just installed the solar heater yesterday, but the hot water coming out is whitish colour until today. Just wonder whether is this normal and how to make the hot water clean?

What you see and think is whitish substance is actually tiny water bubbles. To confirm it, use a clear glass fill it with the water and examine it. If it is bubbles it will disappear in a minute. If it is dirt or something it should sink or float. If the water stays white then there is something like solution in the water tank or tubes.

Thank you for the advice! I don't think it is bubbles. The water stays white. Any suggestion to rectify?

If it is something leach out from tank/pipe is should be cleared after few days or weeks till all the soluble dissolved in water. by then when you complain and the service man comes it will be cleared already and remain mysterious.

I still think it is air bubbles. Let it settles and use a big glass or jug. Worst is if it is anti termite/ant solution drool.gif A drop of anti termite solution makes one little of water whitish and it remains and stays white for months. Someone accidentaly pour in some termite soluton. Ok, not to frighten you too much. Does the water smell? If you have no good nose get children to smell. No wind no fan bring the water close to your nose.

I got a question to ask regarding installation.

The Solar tank is heavy and water is heavy. one litter of water = 1 kg. A 250 liter tank + the stainless steel tank itself + the water in the copper/solar tubes can easily weight 350 t0 400 kg equal to 6 to 7 man standing on one spot of the roof.

The question is do we need additional truss support under the roof with more wood/truss?

One other thing is the roof truss support the roof tiles and it is calculated so and no more. We added the solar tank is one issue and if it stands well all well but our roof tiles are mostly concrete roof tiles. As it gets old after 10 years the shining layer of paint will be worn out. Without the protective paint rain water will be absorbed like sponge and added weight to the roof truss. What next??? Accident waiting to happen??? rclxub.gif drool.gif Has anyone thought about that?

Comment needed icon_question.gif my roof is sinking on one side where the tank sits (senget already)

Asked my supplier, they say a 60gal solar usually wont have any problem unless is 80gal. So, either contractors/developers would b able to advise whether the roof could withstand the weight of the solar or when u purchase, u could also get the solar technician's to check

Thanks for the reply. So you are saying most of the time the installers just install without any additional support for 60 gal solar tank. For me two pieces of wood under one side of the tank have bent recently. I added a 2x5 on these two pieces but there is no way to make it straight. Just make it so that it will not bend further and collapse.

Nowadays metal roof truss are used. Just do not know if it is stronger than wood. It looks very thin.

You can ask tomjason here. He Reno his roof structure by himself. And using metal roof truss. Strong roof structure very much depend on design. A good design can support high load anytime.

Use few more days it should be ok. Similar case with my mom incoming water filter, we replace it and during the first 30mins of flushing it have lots of whitish water, after 30mins flush it reduce but still noticable. And after 1 week, water is clear.
