May 19, 2008 · And, yes, two 50HP boilers in parallel are the equivalent of one 100 HP boiler. All in all, given no other constraints, (duplication of support equipment and additional foundation and piping costs for example) I'd prefer the 2 X 50HP route rather than the 1 X 100HP route IF you have variable loads.

Re: What controls needed for running two boilers in parallel?

Mar 01, 2016 · Parallel primary/secondary is often the most effective and beneficial multiple boiler piping option. It combines the parallel piping for each boiler to ensure equal boiler return water temperature to each boiler, dedicated boiler pumping and then the integration into the primary or system loop via means of a common hydraulic separation.

Sep 06, 2003 · Typically when you're doing multiple boilers, you'll be using some kind of primary secondary situation. The advantage of a parallel arrangement is that the primary loop pump is also you're boiler circulating pump. It's creating your flow through the boilers as well as your primary circuit because the boilers are integral to it.
