标题: 燃气中央空调和安装屋顶太阳能哪个合算
请教大家,已经有燃气中央空调了,使用燃气中央空调和再安装屋顶太阳能,两者相比哪个费用更经济,谢谢

没听明白,燃气是一直花钱的,太阳能板是给家里供电的,不过如果太阳能板不补助,安了就不划算了,得发多少电才能把安装成本补回来啊

就是家里已经按有燃气的中央空调了,还有必要安装屋顶太阳能吗,是继续用中央空调合算还是安装屋顶太阳能合算,安装需要费用,但是太阳能用起来没有费用了不是

看成本了,太阳能那一套系统也是不便宜,如果可以接入电网卖电还好点,如果靠太阳能来发电供热的话,估计不用指望卖电

利用清洁能源是将来的趋势,属于前人植树后人乘凉的事,装太阳能不仅仅是出于经济考虑哦

太阳能涉及的效率问题,现在的科技还不行

這兩者我個人認為沒太大關係。是兩回事

不過現在安裝太陽能,很難回收打平,不大划算。

I agree

We should consider other ways to take advantage of the sun.

i.e.
My friend helped me built a glass house on my existing deck which the bill around nzd 3k. I used my salary raise to pay for the bill. This way we can relax in the sun in winter without worry about the wind and cold. There is only one other house in my street which has glass house.

The glass house use used aluminium sliding door frame with single glass which we purchased through auction site and recycle shop. My friend told me that if I ask commercial company to do the job the cost will be around nzd 30k. I wrote quote/invoice/bom reports for these nz/australia companies

I was thinking about buying brand new double glazing glass, but the cost is too dear and the benefit offered is not so important vs single glazing glass.

Disclosure
I worked in cad company designing windows and doors for about 11 years.

冬天不保暖,夏天特别的热

We live in the house and we feel that glass house is very warm compare to my other rooms. The glass house face north and it became my kids main play ground.

Please read my post.

I installed the sliding door which can be opened during summer. It is the same cool while opening the door as not install glass house in summer. I will install curtain which make it cooler compare to not install glass house in summer to block the sun. It is not wise to stay in deck in summer to get sun bath, right?

Anyway, the length of summer is around same as winter in Auckland my place.

奥克兰那个地方,估计夏天也不会很热
冬天比塔省还冷的吧

澳洲人都比较抗冻,喜欢新鲜空气,这玩意儿不太普遍

He is saying don't do any improvement to your house you are living. Because you might sell it the next day.

If I want to sell my house, I will renovate my house i.e. kitchen and toilets for around 30k nzd before selling the house to get extra 100k nzd. It is stupid not doing that.

As I said, I live in the house and feel warmer in the glass house compare to my other rooms. We cannot stay in deck without glass house in winter as too cold or raining outside. Now my kids stays in the glass house all day. I have not installed the curtain yet and it is very hot if we have sun in winter now.

I cannot stay in cold and that is one reason I left my home city Shanghai, P.R.China and live in north shore, Auckland. The most time in my computer room is around 12 degree and I feel very cold. It is too dear to turn on the heater. I want to save money to buy another house so my kids each can get a house if we die.

I have not painted the glass house and I am too shy to show non finished job. Just imagine two 2 meter sliding door with one one meter window and another 1.6 meter sliding door. That is it. Very simple.

Here is a sliding door similar to what I bought.
