My 10 year old hot water boiler has a 36F temperature rise across the heat exchanger at 100% fire. This seems high. Not certain if it was this high when installed, but I doubt it. The system otherwise is working OK. I think systems are usually set up for <30F temperature rise.
My question is what is the upside and downside of running the boiler like this, and whether I should change anything, in particular switch out for a different primary pump to increase the flow.
Setup: 110K Peerless Purefire condensing boiler, primary/secondary piping with a Taco 007 on the primary. Install manual calls for 008 or 007, and I think 008 would give me more flow and would be an easy switch. I'm heating pump-zoned cast iron radiators and an indirect DHW.
Thanks.
