Landlords

I live in private house for more then ten years and this is my second landlord to whom I pay my rent.He is the owner for more then 6 years. It is very bad times for everebody right now. I came today to pay my rent and my owner told me he wants to add another hundred dollars to my rent because everything is going up.It is truth but I am working only two days right now and it is not affordable for me to pay now more. I have bad times now, there is not much work at these days.The other thing is he didn't heat my apartment very well for last three years and I had another argument with him this year about the heat.Now my heat is very good but now he wants more money.In my opinion he can't move me out at this time of winter because I pay the rent.I have told him, I can't and I will look for another apartment but I am not gonna pay you more money.I just can't believe it he has tried to raise my rent at this time.Who is raising rent at winter?
