新西兰前天开始热水炉的水温不够高，是为什么、（已
在新西兰
前天保险丝烧断了，换了，后来水一直就是lake warm，是不是那个thermostat的问题呢？热水炉不漏水。烦。

自己猜想了一下，是不是那个所谓的温控自己怀了，导致水温反常然后就保险烧了，所以温控现在是不工作的，维持在最低水温？35°？

.........高人高人在哪，请问你热水炉里面的发热系统有几组电阻丝呢？是不是烧掉了一组

去了metre10，老头可真热心，讲解了20分钟。劝说我先不要买那个heater，先买一个新的thermostat,就是调节温度的那个东西，有2个长度，我的是短的。
换thermostat把电闸关掉就可以了，不用放水。先换着，才29刀，观察一下。
老头说很多人会直接换炉子，那太贵浪费了！

等LZ 更新。。。

找个水工问一下不就知道了嘛.解决后请告知什么回事.

开始是连续几天都是不冷不热的水，下午买了温控，把旧的取出来了，然后把新的接上去。看起来有2条线，接的时候其实很简单，就是那个红色线通过这个温控就好了，老头说，随便你从哪头到哪头，只要接上就可以了，有个小螺丝松开，把就线头放进去螺丝扭紧就好了。metre10温控只有2种，短的和长的，线穿好就把温控放进去，就像钢笔套一样不用任何东西固定。
刚才回家发现，呵呵，水开始热起来了，不再是温热的水，水温正常了。

网上google的，大家可以留意：Not enough hot water
This is caused by any of:
1、 thermostat set too low. This can be a problem with new replacement elements, which often have stats that wont go as high as older ones, but sometimes the tank size can require a higher temp to have enough HW capacity.
2、 replacement element too short
3、 For curved element systems, replacement element is mounted the wrong way up, with the curved end pointing up instead of down
4、 For 2 element systems, bottom element not working
5、 With heat banks, a badly scaled exchanger reduces rate of heat throughput, but not capacity. The tell tale sign is that fast flowing HW is not hot enough, but slow the flow down and the temperature is restored.
6、 Insufficient HW system capacity for new appliances, eg power shower
Solutions:
1. Turn up stat. If it won't go high enough, it may be possible to wire it out of circuit and replace with an external stat, but a secondary non-resetting temperature cutout is also now mandated.
2. Replace the replacement element with the correct longer size
3. Refit element with curved end down
4. Troubleshoot lower element & its associated parts
5. Replace or descale exchanger. Consider scale prevention before the exchanger.
6. Applying as many options in Increase Hot Water Capacity as possible may be enough. Turn down shower pumping rate. If these measures aren't enough, a larger HW cylinder will be needed.
2 Element Systems
This variant has a small upper element to give a relatively small volume of hot water which heats faster, as well as the main longer element that produces enough for a shower or bath.

如果换了thermostat水还不热，那个老头建议我再去买heater，大约40多刀，也是有2种长度，看你的旧的culinder是适合哪种。换heater要把水炉水都放干，因为这个是要直接通过炉子表面伸入水里的，只是heater有个橡胶垫，防止漏水，所以如果有轻微漏水，也要考虑这个胶圈老化的问题。都是几十刀的事情。
我很啰嗦。

可能是我的温控之前就因为某种原因出了故障，导致水炉不停地工作，烧掉了保险丝，但是heater没有烧掉，保险丝熔断及时断电保护了它。
我问老头为什么温控坏了，水炉还会有烧水不热，他说温控坏了可能有3结果1，水温完全不热，2，水温温热，3，不停烧，都有可能哈哈。
只要耳朵贴近炉子能听见那个烧水的heater在工作，就表示它没坏。
