<human>: I moved in to a new apartment recently. Lease started May 15th, but we officially moved in May 19th. We've had a few issues, which we're overlooking (including half the light bulbs being burnt out which we're taking on the expense ourselves), but the main issue right now is that we have NO hot water. 

We got our gas turned on Friday night (May 18th). The heat is working fine, but the hot water only changes temperatures slightly (it goes from very cold, to just cold). I contacted my landlord Sunday morning when we attempted to take our first shower and noticed the issue. His maintenance guy promised to come that night and ended up "not being able to make it". No hot water again this morning and he says he'll be coming tonight although I'm not overly confident.

It's in the lease that the landlord is responsible for supplying hot water. Am I in my right to request a deduction on rent if this isn't resolved by tonight? When is it reasonable for me to request a deduction, if it all?

Can you provide a brief overview of the text?
<bot>: No hot water the first three days in a new place. It's in the lease that the landlord has to require hot water. When is it reasonable for me to ask for a rent reduction, if at all.
