If talk about the water waste, yes. It is not worth it.

Like those overnight dish which is harden, hot water is best. Another is overnight harden podridge. You need to scrub quite hard and longtime to remove. If using hot water, would be easy alot. Dish washer using hot water?

Cooking using hot water, shorten boiling time ?

Roof tiles can become solar water heater?

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.

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.

Read back and you know which to choose.

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

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

You reading history lah.

What marketing talk? Can't find usefull infor here?

The size depend on how many person use in your house.

For more techincal detail, you have to google. Or look for some brand on their website. Microsolar have a pretty good technical comparison on their site.

Here we mostly question and answer. And talk kok also.

This 1 we said, good thing don't show you easlly.

It is site double storey house right? They told me this is account office.

Anyway, for solar heater most important thing to look for is the efficiency to generate hot water. How hot the water can generate from the lowest enviroment temperature. Let say that day is rainy day with outside temperature is 25c. Your solar heater that day can boil the water to 50c from the 25c enviroment. That is 100% efficiency. Another efficiency is the water temperature. A cold water maybe 15c can boil up to 60c or higher on rainy day.

If that solar heater can generate 90c water from 0c temperature enviroment, I buy the heater back and put it at my hall to pray it as a god.

We need hot water during cool day and cool water during hot day. But solar heater is opposite. So efficiency is important.

Another thing is, if the solar heater is efficiency enough, you don't need backup heater to stick inside the tank. All the brand accept microsolar have a backup heater incase no hot water during rainy day. Does that tell me the heater is not efficiency enough.

This pictuer tell you a thousand word. --> http://www.microsolarsystem.com/ Why a resort on top of the mount kinabalu will choose this solar heater? Can this heater generate hot water enough in the enviroment which the whole day is damn cold ? This solar heater don't have electrical heater to backup somemore.

Microsolar have pattern technology on their product. They got 1 technology inside the tube which increase the temperature efficiency compare others. Because of this pattern, others brand local cannot copy and adopt into their product. That make the different.

Hope you can understand the techincal explain.

No need buy that good 1 lah. Normal other brand good enough. Most of the day in here is sunny day.

This microsolar heater also look ugly ontop the roof. My friend install this microsolar for 6person ontop his roof. While his whole household is only 4person. Freaking big the heater. Like spaceship landing on his roof.

I don't like the feeling of my cool feet when get down from the bed.

I don't like the whole house with tiling. It just sick to see no different between your kitchen and the room. Wood floor not just look warm and soft feeling. It also feel warm when walk on it.

When I was at those winter country, I understand why they have a wood floor or carpet or wear a stocking. Those tile floor (specially toilet) really really cool. That you don't wish to walk on it.

It is an age technology that many have forgotten. And new generation now born without any knowledge it at all.

How about the handle turn all the way to hot water side? Is the water hot enough?

This look like the Solar heater have problem. Normally still can retain the water hot. Given no whole day raining. You need to complain to the developer or get the brand and direct contact to them to check.

Most of the solar heater have heater element inside. Incase few day rainy day. Than you need to switch it ON.

The hot water take a while to arrive is because the pipe is not insulated. The water in the pipe is cold down. And the longer the pipe, more water is cooling down and longer time to arrive the hot water. This is 1 of the disadvantage having solar heater. It is kind of waste the water to wait for the hot water.

To solve this, got to insulate the pipe. And not using the pipe larger than 1/2" to minimise the heat loss. Also some western country using pump to return back the cool water to the heater. Some kind like a circulate.

There is a former having same problem as you back than. Got to change the tank. Try to read back. Or maybe somewhere.

It is pretty normal for any sale people to switch product and sale. Since the product is not own by them. Price, company problem, not popular and etc are some of the reason. There is no way for you to hold your principe of sale when thing and situation are change.

Just we here forumner consumer forget that he is same like others that selling something here.

I no longer buying any expensive product base on some people or saleman talking. Since we have internet.

You can search, research, review or do anything in the internet. We have to change our way of buying something. That help me to learn a lot.

Sometime he want to be a consumer. But forget he is a saleman also.
