灯油タンク再び凍結。あきらめて室内に入れる　Frozen kerosene tank again. Give up and put it indoors

コーポ銀河101号室の灯油タンク、再び凍結しました。何度も凍結を起こすので仕方なく室内にタンクを移設しました。
The kerosene tank of the corporate GINGA No. 101 room was frozen again. Since I cause freezing many times, I had to relocate the tank to the interior without any help.

この物件を買ったときには、灯油タンクは室内にありました。それを私が室外に出したものです。過去に室外に設置した跡があるにもかかわらず室内においてあるのは凍結のためだったようです。
ちなみに、この横の部屋も灯油タンクは室内にあります。2階の2部屋は物件を買った当時からタンクは室外にあり、今も凍りません。同じ北向きの場所においてあるのに、凍ったり凍らなかたりする。日当りとかちょっとした違いなのでしょう。
When I bought this property, the kerosene tank was in the room. That is what I got outdoors. It seems that it was due to freezing that there was a trace that was installed outdoors in the past but it was indoors.
By the way, the kerosene tank is indoors in this side room as well. Since the two rooms on the second floor bought the property, the tank is outdoors and still does not freeze. Even though it is located in the same north-facing place, it freezes and freezes. It might be a bit different about sunshine.
