Heat exchanger/forced air on baseboard zone
Hi All - I inherited a home with many additions over its 150 year life. One problem i'm having is in the kitchen addition that was added 10 years ago. The prior owners cut a lot of corners when building the addition including the heating cooling. This is a relatively large space and has lots of windows and doors - so it gets quite cold in the mornings.
When I did some investigation I discovered that the t-stat only controls the air handler - and has no connection back to the circulator pumps at all. Then I traced all the piping and found that the heated water supply to the air handler is on the end of a line of baseboards in another part of the house. So to get the kitchen warm I have to crank the heat in the other room and then make sure the blower is running in the kitchen.
1 - Assuming I am ok with the kitchen being the sole location for the thermostat for the entire zone (kitchen and other area) - is this as simple as splicing the right wires from the stat to my Taco control unit? That way when it calls for heat it not only starts the blower but also the circulator pump for the zone.
2 - The kitchen is an area that is very occupied and needs heat most of the time - while the other room on the zone does not. Ideally i'd like to create a new zone for the kitchen air handler. I actually have an existing zone that isn't used and I was thinking I could just get a plumber to connect the air handler to that. Then I can take the current line that goes to the air handler and connect it directly to the return side coming out of the handler (basically by passing it). Does all of that work in theory, or are there things about the air handler that would be different than baseboard that I need to worry about?
Any help or gotchas appreciated before I start to talk to plumbers to make the updates....
