Trinity vs Munchkin

Troy, I have used a couple of Trinity boilers with good results. You have to pump the heck out them and I would never pipe them as the manual suggests. My question is about the cleaning. Please explain what plugged up and how you cleaned them.

    We're looking to expand into condensing boilers. We installed a Trinity recently and also have Munchkin boilers fairly readily available to us. It seems they're similar in many ways. Any reasons to choose one over the other?

    I have installed many Munchkins. I am very happy with their performance and reliability. We disected a Trinity boiler and were not real impressed with the fit and finish. It looks like someone put it together in their basement. They use the same coil for their heat exchanger but they are using the munchkin 140mbh coil for their 200mgh boiler. The other difference is they manifold the coil to a 3/4" header where munchkin uses a 1-1/4". Like I said if you pipe and pump to overcome the head loss I guess the Trinity works. I can't help but wonder how long a life the heat exchanger will have. I have found that the Munchkin does need to be cleaned a least every 2 years. Probably should be cleaned every year. They will shut down when this tight heat exchanger starts to plug on the burner side. I think any high efficiency boiler is going to take more careful design and more maintenance.

    Munchkin cleaning not needed unless a problem occurs

    The Munchkin does not need to be cleaned each year. We recomend it is checked every two years for these reasons.
    The service contractor can recomend to the owner of the Munchkin that it be inspected a min of every two years to ensure proper operation and to inspect all water exposed equipment to ensure no water is leaking from them that could cause damage the the Munchkin and/or other components.
    This will allow the service contractor to offer a service contract or a set fee or an hourly fee to provide this service and make income doing so. The owner of the unit will have a sence of comfort knowing that it is being checked for proper operation and safety.
