Our house has a GH 2000 Stainless boiler that is 8 years old, I've only been here for the last two years though. Since then I've installed a flow meter in the system next to the furnace in the house. This spring I will be opening up the system to reverse the pump which someone installed backwards, the house is on suction instead of pressure. When it's open I will install tees on each side of the Hx for temperature gages to monitor temps before and after the Hxer. Other than flow and temperature is there any other sensors that might be nice to have on the system? Thanks.
