A plumber is someone who fixes water-pipes and heating systems. I was explaining that I missed a point in an earlier post because my boiler has gone wrong. I was upstairs in my study working, but I was wondering what the plumber was doing downstairs with my heating system - so I was distracted and not concentrating on my work properly!
Please explain the highlighted words.

On the 2nd floor of the house there is a room, a study, that has a desk, books, a computer. It's a home office.
