You never believe this. RM1800. This is not price from manufacturer, this is Malaysia retail price! Besides, there are 2 spare tubes for every unit. The heaters are meant for US market.

So, suggest zheilwane importing one container so as we have someone who can provide after sales service.

Installation within klang valley with standard length pipe RM600. Out of town RM1k to RM1.5k for 1/2 day work and travelling.

Err... All the documents are with my sisters. Will get from one of them. Tomorrow leaving for Singapore and will be back on Sunday. Till then.

By the way as you can see from the picture there is a copper coil, this mean tap water flow into the coil and get heated up by the tank water and then to the taps/shower. Another tap water supply to the tank control by a float like our toilet float machanism. The tank does not have a pressure relieve valve as when pressure/steam is generated it is release by the hot air exhaust pipe. There is no danger for high pressure tank that cause tank explosion. Because of the massive copper coil in the tank, the tank is much heavier than conventional solar tank.

There are 20 tubes, if you broke a tube and have no tube to replace (as said they will give you 2 spare tubes) you can seal the tube hole with silicon and use 19 tubes.

There are two types of vacuum tubes. One in the picture is the cheaper type simply a vacuum tube where sunlight heats up the water in the tube. Water will circulate inside the tube with cold water flow from the tank down and hot water rises back to the tank. This is the model I bought. The other is more expensive like micro solar where the vacuum tube will not have water but a copper rod. The sun heats the copper rod and transfer the heat to the water inside the tank. That means for the cheaper one there is a range of angle you have to install never beyond the recommended angle for water flowing freely in the tubes. The more expensive copper rod tube type has no problem how you place as there is no water flowing inside the tube. Also this type of heating need no direct sunlight, the copper rod will keep absorbing heat from surroundings even thought it is snowing!!! Any heat will be gained by the rod via vacuum to the rod. But here in our hot climate need no such, absolutely not necessary waste of money.

one thing i must warn you, the vacuum tube on the inside can be boiling hot within minutes under hot sun. The tube got two layer of glass you will not feel the heat holding it on the outside but inside can be more than 100 degree C without water. you must not put the tubes under hot sun while installing. It has to be cover with thick black plastic sheet, not old newspaper as the sunlight can penetrate the paper and heat the tube inside. Fixed the tube at last after all piping. But you got to fixed a few (4) tubes during the installation of the tank and bracket, adjusting them. After which take the tubes out and complete your installation then fit the tubes and quickly turn the water flowing into the tank. Be careful it is thin glass, it breaks. So, take the whole box up the roof and open it up there and then.

There is no high pressure in the tank for this design as you can see there is a small refill tank and exhaust pipe, and also the coil where tank water and hot water outlet dont mixed therefore need no thick tank, is not an issue.

Look like you have done a lot of reading.

Talking about hybrid. What if you do not use aircond for a day and how are you going to save? Still solar is absolutely free except for the cost of capturing the energy. Hybrid are not popular here and I afraid not many people can give you the feedback.

About pipes. Why do you want these "new" pipes for hot water? Price, better heat insulation, flexibility in installation? Why would you want something you are not sure when you know copper pipe can take more than 100 deg C and more than 4 bar the new thing can do?

I still prefer solar water heater and instead of copper pipe, I prefer the thin stainless steel pipe with copper fittings.

Cheers

It chilled the feet and make you sick. That is why we have the cloth liked slippers just for that, "curi" from hotel whenever we stay.

My mum from China. When i was a kid some times she washed her feet with hot warm water and said they did it often during winter washing family members feet especially the elders just before going to bed for health reason. Feet are to be kept warm, it connects all our body organs. I think it promotes blood circulation and recuperating the day cold feet for the night.

If you are thinking of ROI from electricity saving you can forget about solar water heater. Putting the same money in investment instruments you can easily get to double the money in 10 years time. How are you going to save 2 times the electricity saving? In other word, you can never get your savings. The only consolation is electricity is going up and up.

It is not about savings but life. You got to enjoy life and not only you but all the family members including your father and think about it how long your dad is going to live without being able to enjoy good shower anytime he wants? Another 10 yrs, 20 yrs? Like the saying, in life how many 10 yrs do you have if not doing it now?

Not all hotels have good shower. 5 stars and above and that costs RM300 a night stay. Haven't enjoy a real good rain shower after a hot day work? Go play golf in the morning and finish your 18 holes by noon your body feel heaty, tired and hungry. As you step into the shower room, wah lah heavy warm rain pouring on your body Though hungry it is so reluctant to walk out of the shower . As you walk out you would tell yourself I would be back (for the shower) now go makan, otherwise you would think how good if I can have one at home. You could have not only one but all your bathrooms with solar water heater.

Not forgetting also,instant water heater does not give you hot hot shower with huge lot of water. When I feel a bit not well I would have extra hot and extra long shower and I would be feeling much better. Even when sick I have no hesitation going for shower as I know I would be pour with lot of hot water and woiuld feel well.

I read that Japanese dip themselves in 40 C hot tub and enjoy themselves for hour.

Forget about bathtub, we dont dip ourselves in tub as we have no winter. Not even jacuzzi. In cold countries as the weather so cold and nothing to do outside and nobody wants to go out too cold you can spend hours in the hot tub. But here you got thousand and one things to do just cannot sit in the tub reading books and a wine by the side. Instead make a shower screen.

Roof leak usually at the joint angle and not at the wide area usually solar heaters are placed. Unless it is tank leak. Also when solar tank leaks, it drips to the roof and to your gutter not your ceiling for the stand alone type where tank and solar panel on the roof unless it is a split heat exchange type where the tank is below the roof and solar panel on the roof. But if it is storage then it drips to whatever at the bottom of it.

The maintenance is just changing the non return valves once every 3 years.

Lime builtup, not calcium. Lime the white things you see in kettle heating element. Since seldom use the heating element of solar heater, this is a non issue.

By the way, this december lot of rain and cloudy days, only one day we had to turn the hot to the max but still it is warm enough for shower, next day with little sun in the morning it was good for the day. Since then it is ok. My solar heating element ko long time and never replaced.

Well said. Some comments.

1. Not many houses facing exactly N and S. Between N and S for Malaysia at a little N of equator, S is better.

2. Still on solar panel positioning. Try get morning sun instead of afternoon. That is facing East. Therefore the better position is between South and East or southeast.

3. You might be surprised buyer prefer buying houses with solar heater installed. Not only getting a solar heater but also hot and cold piping already in placed means saving money doing piping. Moreover, it comes with mixture and rain shower. Therefore the investment is not lost. Imagine you come across two houses one with and the other without the choice is obvious and you do not mind paying a little more.

4. Roof tiles is less to consider. The older the roof tiles the harder it is. Maybe just need another coat of paint. Inspect roof trusses is a must. Just need to place additional support by having few pieces of roof trusses on the load bearing supporting the heater tank.

5. GI pipe. With our without water pump or solar or storage heater need replacement anyhow.

6. Alternatively, just installed pressure reducing valves going to WCs.

7. There is no ROI from electric bill saving against instant water heater due to huge price gap and cost of installation/piping. The ROI is on having enjoying better shower. Yes, there is ROI against storage heater.

Just my experience.

Like cassette. Can play and record any songs from radio anytime.

With our hot sun it does not matter tube or panel. Just make sure it is a reliable brand from a good company and most of all after sales service someone you can rely upon when you need them for service and warranty claim.

Aiyoyo. why put all the blame on a sale man la? You people are funny. Look at the big picture man. He is not the owner of the company that got into difficulties. How the hell he knew it would end up like that as a distributor. So was one of you paying a deposit and not knowing would end up like this.

In this competitive business world it is normal, very normal for companies getting into difficulties and close shop and there go all the warranty and promises. Even banks big businesses, renown companies go burst. Lehman brothers, AIG, etc whom people trusted them with their money and lives savings! Even the trustees of the investors also got into trouble, remember 2008 credit crunch?

What do you expect a distributor or a reseller to do when the product he carried from the company when the company got into trouble. He has to survive and lives have to go on and feed the family. And so he switched brand to the new better promising company. Likewise, if the company you work with go bankrupt or in financial trouble no longer can pay your salary what do you do? Yes, you look elsewhere for a job, you leave that company, you cannot afford to sink with the company that is obvious you need to survive and feed your family and pay your house instalments, etc whatever. So all the promises you made when you were with the company to your customers cannot be fulfilled are you to be blame?

We cannot expect the salesman or the distributor to sell other products but still solar heater, the product he knows best. We cannot blame him for introducing us another solar water heater brand, can we? We cannot expect him to go sell potatoes or kacang puteh or car, right? Likewise you too will look for a similar kind of job you know best. If you are a software programmer don't tell me you go build bridges and highway. No way! No that no one will hire you but you yourself do not believe you can build bridges.

For that we blame him and ask him to sell elsewhere and not here in lowyatt? Is that fair to disqualify him? So the programmer who did a part of the program in the software product sold to many customers in Malaysia now has to migrate to Singapore or Australia?

Why sell the product from the splinter group? Who else or other brand you expect him to sell but from people he knows and he trusts? Microsolar? monier? or some china brands? You think you know everybody and everyone want to recruit you to sell their products and give you good margin? There are 6 or 7 billion people in the world you but our friends circles are narrow.

Still he tries his best to help but you people not only not appreciate his help but also frighten or make worry other formers from buying from him. To me he is a good and honest salesman never run away and try assuming responsibility that wasn't due to him.

By the way, I am only a former here. I just want to speak what is right. A good business person is hard to find and when we have one here you people don't understand.

A piece of advice. Never put a deposit when you not needing the product in a month regardless the offer. The company or anything can happen. The longer it is the higher the risk.

Why so secretive? Why cant just post photos here? If not prepared to share just don't post comments cause people like me just ignore all that had been said. Cause by pm you with phone no then one fine day someone call and sell you solar heater. Funny selling trick? As far as I know locating the panel for max effect is as easy as 1,2,3 for solar panel installers.
