Heat Pump Hot Water tank installation Q's

I'm looking to replace my 15 year 50 gallon hot water tank, with a HP hot water tank. My tank is in the garage and I live in Florida if that helps. The tank now as a T/P drain line which goes under the cement slap to go outside and it's about 15'/20' line. It doesn't have a catch over pan, so I don't have a drain near this tank. What can I do with the Condenser drain from the HP? Could I add it to the T/P drain pipe?

Most areas require the T+P discharge to be a separate line.

Ok I could either go under the garage slap which would be 20' or so.

Go through studs of a garage wall which is a inside wall of house. 20' or so. Little better maybe?

Go through studs of a garage wall which would a little less of inside walls but not straight to go to the whole house condenser drain. Little Little better maybe?


What would you do?

The T/P can not directly connect to any other line, but it can go down right from the tank to about 4" above a drain pan.

So if the valve leaks it will just drip into the pan.

From the drain pan line, connect the water heater drip line down stream, so the drip line will not fill up the drain pan.

This is how my GE heat pump water heater is, works fine and is to code.

Another option for the condensate drain would be to get one of those small condensate tank/pump combo's built to use for similiar situations with central A/C systems that have no gravity drain available. Then you could pipe the pump's small drain hose overhead and out without tearing up your concrete garage floor.

The hot water tank is in the garage which is lower then the floor of the house, so it wasn't built with a drain pan.

My only other way to do this pipe to the central ac drain pipe. I would need go in an internal wall behind a bath shower to get to the drain pipe but it should be easier then the slap cement drain thing.

Could I drill a small 1" hole in the garage floor to drain this condensate?
