For me solar water heater is useless in Malaysia except .... (later on this) During hot day, you get plenty of hot water but why you need hot water to bath in hot day? During rainy days, you just have water than is not hot enough or not enough hot water  I'w say even with electric water heater, the hot water storage tank is not holding water long enough for next day. Probably lost most of heat at night time. Someone who has been installing this said, it is not worth the investment. Almost useless. The only thing that you can benefit is that if you use hot water in your kitchen like for cleaning greasy plate etc. |

QUOTE(kk131 @ Apr 23 2018, 08:49 AM) I don't know what experience your statements are based upon. I've live in 2 house were we installed a solar water heater, the first was a plastic panel type, it was good most of the year apart from a few days at the end of the year when the water wasn't warm. We have a vacuum tube type panel now, the performance is much better, I would estimate there are 2 -3 days/year when we have to use 100% water from the hot tap for a shower. We don't have electric water heaters. It is from several people who owned the solar water heater. Probably depends on where you live. If you are from small town go to KL, the feel the water is never cold. Hardly use water heater even in the morning.  If you have rainy condition for several days like during monsoon time, will water be hot? |

QUOTE(kk131 @ Apr 23 2018, 09:08 AM) Read my post. With vacuum tube type, the water is still warm, even during the condition we experienced late last year. Seems like you're relying on second hand information, not personal experience. I read about vacuum tube or I believe you meant vacuum storage tank. I was asking during cloudy days for 2 or 3 days, how hot was the water? Can it get hot enough based on your experience? |
