Not sure if this link will work or not..
I had a thread I started a while back about the plate hx.
First off what kind of of heat do you have, Force air or radiant?
Here is how my system is set up.
I have a forced air system.
So the hot water comes in from from the owb, into the house, then into the plate hx, out of the plate and then into the water to air hx in the furnace plenum then back to the owb.
The water from the owb is always running through the plate hx.
The water domestic water is tied to the other side of the plate hx. So as soon as you turn on your hot water, the flow starts through the plate, transferring the heat from the already running water from the owb.
Some people run their hot water directly out of the plate. I chose to run mine out of the plate and into the water heater. It uses the tank as a storage and tempering tank.
Also on this set up you would want to make sure that you have a tempering valve installed on your tank.
I have just a small 10 plate, that cost like 40 bucks.
Hope that was clear and helps.
