    what would be normal heat loss with a flat plate heat exchanger? I have a central boiler 6048. I have a about a 1-2 degree heat loss from the boiler to the heat exchanger. The heat loss between the flat plate and the boiler is about 24 degrees. Is this normal? Seems like a lot to me. The distance from the heat exchanger to the boiler is about 3 feet. All the pipes are wrapped with foam insulation. What do some of you have for heat loss in degrees?

    If you are transfering heat through the hx, then the 24* drop is really your delat T. If so, that is pretty good transfer going on. If you are not supposed to be transfering heat, then you are radiating a lot of heat from the plate hx!

    Yes. I'm transferring heat to keep my oil boiler up to temp. Is there a way to reduce radiating heat from the hx? That is about the only part that isn't wrapped in insulation.
