3-in-1 hydraulic separators make air removal and dirt removal primary functions, along with hydraulic separation, with no added piping connections or installation costs. Magnetic dirt removal adds a fourth function to the above. Caleffi’s SEP4™ is available in sizes 1” to 2”. Magnetic separation is especially effective for older system,Caleffi Hydronic Solutions,Manufacturer of high-quality components for heating, plumbing, air conditioning, heat metering and renewables systems, for domestic and industrial plants.Piping layouts to avoid in hydronic systems - HPAC Magazine,Properly designed primary/secondary systems work.

The key detail has been a pair of closely spaced tees that couple the secondary circuit to the primary loop in such that flow in the primary loop has very little tendency to induce flow in the secondary circuit.

Primary Tee Direction with Low Loss Header Secondary,

Drawing A is what I consider a primary loop with the boiler in that primary loop. Pipe size and circulator selection need to be correct to move the required gpm The secondary loop circulator pulls the required gpm from that primary loop. There are a handful of ways to pipe primary secondary piping. All methods have advantages and disadvantagesUnderstanding Primary Secondary Pumping Part 6: 5 Ways to,,Primary-Secondary-Tertiary Pumping. In a primary-secondary-tertiary system (Figure 3), things start to get a bit more complicated, but the principles are all the same. The common pipe (whether it is between the primary loop and the secondary loop, or the secondary loop and the tertiary loop) acts as the decoupler, so flows act independently of one another and there is extra degree of thermal,Piping layouts to avoid in hydronic systems - HPAC Magazine,Properly designed primary/secondary systems work.
