Cracking & splitting baltic pine floors

Gidday all

I have a problem and was hoping that someone could provide me some advice or had encountered a similiar problem.

I have a 100 year old home and about a year ago I had my baltic pine floorboards sanded and poilshed (polyutherene). Once the job was done they looked excellent.

Then in July this year we had our old ducted heating system (ie; 15 years old) replaced with a new more efficent unit.

Then in the last month or so. I have started to notice that some of my floorboards were splitting and cracking. Some are like hair line cracks but then there are a couple of others which are wider and run 120cm in length.

At first I thought they may have been caused as a result of movement in my house. But I have no cracks in my walls or architraves so ruled that.

So I thought it must be my new ducted system causing the problem in that its drying all the air under my sub floor and generating a bit of heat under there. The strange thing is we didnt have this problem ( floorboards cracking) with the old heating system we had.

My sub floor isnt that big in that a slim man lying on his back would have little or no room under there.

Also when I was look at some of the cracks with a torch. I can see the duct directly beneath the crack. So I assume that they are touching some of the floorboards underneath. So wasnt sure if this was the problem.

This is really starting to concern me and I dont want these cracks to get any worse. As I am not even sure how to fix the cracks and if its worth it when it might happen again.

So I am looking for some help or suggestions of what the causes maybe as to why my floorboards are cracking and how I can fix it.
