Direct Pump TT Solo 110 with 3 zones
I have 3 zones with the following flow requirements:
Zone 1: 4.6 GPM at 30 degree delta-t.
Zone 2: 1.8 GPM at 30 degree delta-t.
zone 3: 1.0 GPM at 30 degree delta-t.
Oversized, cast iron radiators in all three zones.
I've been watching the ongoing discussions on circulators ....
If I were to direct pump the TT Solo 110, what circulators would you suggest I take a look at? My question primarily centers around maintaining the required flow through the heat exchanger. - there would be times each zone would be the only zone calling for heat.
