ha ha yes we tried that it does not work...the clients plumber or contractor would say who are you to demand such photos...you are only a supplier, dont be so arrogant, etc etc...and many times the plumber already left job site maybe due to disputes over payment....we do not want to get sucked up into these disputes...what we end up doing is take photos on site of existing conditions as found on installation day..and if any pipes are missing not in accordance with what the client had certified had been done, we inform client and send the pics immediately..most times client will say he will get his plumber or another plumber to follow up and will take responsibility for further complications if any..
it normally does not happen...most times the clients plumber has done their job diligently but sometimes due to payment disputes or whatever it is not done and the clients plumber has left jobsite and did not tell client...

and if it is a small amount of piping one or two metres missing and our people have enuf in their truck the client might ask our people to do the small lengths.and pay directly to them..but in this case the length of missing pipes was much longer .. we told the client about this on site and client received our email report with pics in ceiling of missing piping one or two days after installation...he got his plumber to go up and do the missing piping and in fact said our water was very hot ...that was before the bent over vent pipe incident...if the vent pipe was bent over on day one with the water pouring out as client asserts...the shower water would not be hot...so the vent pipe was probably bent over a few weeks after the clients plumber had completed his work, that is one month after microsolar installation...the whole area houses were empty...owners had not moved in yet...still under construction...lonely deserted construction site at top of hill next to forest during the intervening one month..how can client be so sure no monkeys climbed on top of his house?

Just for checking, without doing any repair, mobilisation cost to get an experienced malaysian plumber team up to the roof with lorry, long ladders , tools etc minimum is rm350.00 nowadays...
.To do the servicing labour..ie clean valves, fittings, glass tubes etc add rm150.00. any fitings that have to be replaced will be as per cost of fitting...

.unfortunately your friend did not want to listen when we trying to explain... ...we are only trying to help as he is our customer altho somebody else bought it for him after studying the other options in the market....our people have the experience to diagnose the problem and service the unit and to make the water hot so that the customer can carry on saving electricity..no point paying inexperienced people who do not know how to solve the problem...we believe that if customer is going to get people up there they must be able to solve the problem...no point if water is not hot on cloudy days or customer must switch on electric heater every now and then...defeats purpose of getting a solar in first place
..might as well install instant electric water heater...we believe it is all about saving the customer money...

bottom line is , each microsolar m60vthe saves rm1200 per year on electricity family 4 pax, we budget 10% for servicing, that is , within the budget of rm120 per year for servicing ...within this budget (and we are well below this budget for your friend) we ensure the customer gets the most skilled an experienced plumbers up onto his roof to do the best job...as mentioned we have customers from 22 years ago water still hot very happy...this is not easy to achieve, it requires highly efficient solar collectors, low maintenance design, best possible materials and experienced workmen ...how many other brands of solar water heaters in malaysia or in the world can do that...you can ask around..
.think of it, why do people pay more for the quality of a bmw or a ferrari when a proton can still get you from point A to point B? a proton may not last as long nor go as fast, but it still gets you around...on the other hand, we are the undisputed highest temperature solar heater in the world, but we try to charge reasonable prices , not as low as a proton, maybe more like what toyota charges, but we deliver to the customer quality and performance of a bmw or ferrari ...

malaysian water is dirty, that is why need to change vavles that are clogged up with limescale every 4 to 5 years. there is strong air pollution in klang valley, so the rain that falls in water catchment areas is acid rain from the carbon dioxide pollution from vehicles, cannot drink it directly, will have osteoporosis. So the Jabatan Bekalan Air or Syabas or who ever treat the raw water with lime powder calcium carbonate to reduce the acidity, to a neutral pH 7.0 thereabouts, . this calcium carbonate is dissolved and will pass thru your whole house water filter, and will precipitate out as solid cement white deposit on anything metaliic and hot, such as the solar vavles. You can see this limescale on the old style electric kettles heating element.

Solahart may not require service , probably their valves are stuck with limescale but they may not know it since they are using electricity backup heating , your relative is spending a lot of money. We have to compare apples to apples, try to switch off your relatives electric connection to the Solahart and see what happens. Does the water turn cold?

As for cost , if your relative is using electricity on cloudy days then he is not saving much money on the solar water heater. Defeats the purpose if your work out the ROI. Electric instant water heaters use up RM1200 per year on average for a family of 4 pax. storage heaters use more than that. A Solahart with 300 litres tank with 3 Kw booster would use way more than RM1200 per year. Using a 3 kw booster for 1 hour per day cost RM1.50 calculatied at RM0.50 per kwh unit x 365 days = RM1642.50. Your friend should check the calculations carefully.

But Microsolar saves RM1200 per year, of which you set aside 10% for maintenance, so as long as the servicing budget fall within this 10% budget that is RM120 per year, , you are still saving 90% of the overall savings. if Solahart which is a famous Australian brand was so capable of heating water without electricity, they would not have disappeared from the market. Their are the only brand of solar water heater which is still using old 1950s style galvanised iron tank with ceramic coating, all others brands , Microsolar included are using 304 stainless steel tanks. However Solahart and Microsolar are the only brands to use double walled tanks, but Microsolar uses only water, whilst Solahart uses Hartgard a red glycol toxic chemical that may leak into the household water pipes when the g.i. tank starts to corrode. We have taken down many Solahart tanks with this problem.

Indeed worldwide all solar engineers know that the Malaysian Microsolar multivavle coaxial patent has superseded the Australain Japanese Solahart Patent on single vavle solar water heaters.

But we also have 22 years old MIcrosolar never been serviced water still hot, how do you account for that? So it is difficult to say, with sediment and limescale and other impurities in Malaysian water hard to tell what the servicing interval will be. Many of our customers do not service for more than 8 years, although we do not recommend it. And then again sometimes sedimentation and limescale clogging up issues are accelerated cos of extended water cuts as had happened on Klang Valley, so it is hard to predict.

yes we have other emails but for our customers convenience we still keep our familiar microsolar@hotmail.com email , nothing wrong with it, our customers like it. in fact we keep our telephone nos too, but use mobile numbers more nowadays.

and quite busy on site these days, with ongoing installations but we do check email daily.
