Toester heater waay at the end of the line

Mikey1970

Hello

My 10 year old kitchen tacked onto the back of my 100 year old home is freezing.

The Toester under cabinet fan/coil does not blow all that hot because it is at the end of the line.

The remainder of the house is the original cast iron radiators. 



I was thinking that one way to increase the heat input into the kitchen would be to repipe all the hot water to run through the toester FIRST, then to the rest of the house.  Also, I would run a second toester in the kitchen, piped in parallel to the first one.

My system is a 2 inch gravity system, with a circulator added decades ago. 

I plan on using PEX for the to/from toester connection.  It will be easy to work with and not alot of elbows.

I might be significantly lowering the gallons per minute thru my system, but I am not sure what the affect will be. 

Thoughts?  This looks good on paper.
