Buderus gb142 quit
Hello, looking for some advise. My current set up-buderus GB142-30 multi-zone LP gas. Only filtering is a wye strainer. Feeding 5 cast iron radiators and one hot water coil on an air handling unit. System has run well for 15 years with normal maintenance/servicing.
Now starts the problems, multiple service calls for ignition issues. Can’t seem to get reliable ignition. Unit would work fine then require a reset. Service tech could not get unit to fire consistently. (I lost confidence in company doing service as well) Pump control board burned up, and the wiring harness connection has black arc tracking on it. I do not want to plug arc tracked connector on to a new pump board. Nor do I want to start replacing wiring harness on a 15 yr old buderus. I’m almost half way to a new boiler in parts costs.
Was going to replace buderus with a Lochinvar NKB110L heating only unit, but it will take 6 weeks to get that unit. At a local plumbing supply I found a laars MFTHW100 that looks comparable. They stock replacement parts as well. though I know the turn down on this laars model is only 5:1
The supplier is recommending running a water treatment agent in the system, the MC3 cleaner and treatment. I found a magnetic separator on supplyhouse the magnaclean pro 2 XP. Would this be a good idea introducing a cleaner/treatment into a system that has been operating well for 15 years? I do not mind investing if it will give me a better system. If I understand correctly this mag cleaner gives me a way to introduce the cleaner into the system as well.
Thank you for your time and input.
