Hello new to the forum. My question is I would like to install a Taylor 750 to heat my home. I was wondering being an open system can the furnace be installed below the basement where the pump is going to be. I would like to run three pumps for three different zones. I thought about putting a pump down on the furnace a pushing the water up the hill but I'm not sure how to do that and keep my three different zones all on different thermostats. My thought was that the pump on the furnace would have to run all the time and then pull off of that with 3 more pumps. I would like to do this with less pumps as possible but maybe that is not possible. Any advice would be appriciated.
