"Had three small gas explosions"
Installed 11 years ago by licensed contractor. Have had problems every year after first five years. Early problems with pressure switches. On New Years had Ignition Fault. For unknown reasons, had gas build up in chanber and lead to three small independent explosions before found out what was happening and unplugged everything. First explosion blew off the exhaust air duct. Fortunately no fire. Service disassembled boiler and cleaned completely. I keep the Munchkin Boiler Fault led Code posted for ready reference at all times. Working again but scared of another explosion. May have to replace entire system.

"Too Many Faults - Too much money"
We had our Munchkin professionally installed by a very good plumber (certified Munchkin installer) in August 2008. The unit has had annual cleaning and servicing by the same Basking Ridge nj installer. We have had Faults 9, 10, 11 & 13 periodically causing regular maintenance expenses. This past October we had to have the blower motor replaced - one year after warranty expiration - at a cost equal to 10% of the original purchase and installation price. Then another series of faults. Installer said that he has never needed to replace blower motor and that we were merely unlucky. To me, when there is this pattern of faults and a high cost parts replacement it is not a question of luck, rather, it is a question of installation quality, product quality or some combination. We bought the unit on the basis of its purported efficiency...trust me, whatever value we saved on energy expenses has been eaten up by repair and maintenance expenses...therefore, the efficiency claim must be weighed against likely overall expensive cost. Both the Munchkin and installer have proven equally disappointing.

"Worse purchase ever"
This boiler has so many problems I consider my heating and air guy one of my best friends. Be prepared to spend a lot of money yearly fixing the problems that occur.

"Munchkin are under sizing the gas line and venting"
Most issues around the Munchkin are under sizing the gas line and venting. Make sure that the venting line has been glued properly (this will destroy swirl plates as not gluing properly will allow gases to go back into the unit). Sidewall or roof venting is fine as long as there is nothing blocking the venting (so gases do not get sucked back into the venting).

"GOOD boiler IF installed properly"
The Munchkin boilers I have installed for the last 12 years have had very few repair calls. The most notorious part for failure is the water pressure switch (pro code). If it is burning propane it must be cleaned yearly, On natural gas at least every two years. If you are losing the blower or 925 control it is caused by exhaust gas reversion or gasses rising out of the blower intake after the blower shuts off. I will let you in on a little secret - most of the high efficient boilers use the same internal parts. So bashing Munchkin when the only difference between it and Lochinvar Knight floor model,and many other brands is the controller. 99% of problems are caused by improper installation. Yeah I know YOU have heard this before but IT IS TRUE. Proper venting of ALL high efficient modulating boilers and furnaces is very critical. One of the inherent problems with Munchkin boilers is the lack of fall to the drain line - it has a bad habit of plugging up. When it does then you get F09's and F10's. plugged drain lines also destroys the front and back refractories. If the flame rod comes out with a reddish tint the boiler is holding water in the combustion chamber, If it comes out white you have exhaust gas reversion. I don't care what the install manual shows the exhaust pipe MUST be at least 18 inches above the intake pipe or 6 feet away down wind of the intake. Also call the distributor for HTP products in your area and find out who they recommend for service in your area. ( they give out my name here # These are good boilers. If you need to have the boiler replaced under warranty pay for the upgrade to the NEW ELITE FT. It is the new fire tube design that has been out for over three years now. #Triangle Tube was the first I believe# That is all that I install now. I don't have a problem with the older giononi style heat exchanger, I just believe that the new design fire tube boiler is far better. The new design still should be serviced yearly but it doesn't require yearly cleaning. I installed one of these 1 1/2 years ago and it cut their gas bills 40%. Usually savings is 25 to 30%. I have munchkins installed that the customer doesn't service until there is a problem. It usually takes 4 or 5 years to build up enough crud to cause a problem when the boiler is installed properly. I installed a Munchkin T80 and on purpose never took the cover off other than to install it. I never checked the combustion or any of the settings. All that I did was hang it on the wall, hook up the gas and water piping,hook up the electrical and thermostat wires, filled the system, purged the air and threw the power switch. This boiler ran with not one miss fire in three years. I know this because the computer hook up that I have shows the history ) After three years I notice the flame rod was getting dirty. This boiler had a layer of crud three inches wide and 1/4 inch deep inside on the bottom of the heat exchanger. did a before and after combustion analysis and I gained 1% by cleaning. This was my own boiler heating my in floor heated barn to 50* all winter for three winters. 0 Problems.

"Worked Fine"
I've had my boiler for 7 years. Error codes began 2 years now all is fine Here's the code to making these boilers sing... Make sure exhaust is 18" away from intake (acidic air will rot intake fan) Make sure co, co2 are adjusted properly clean combustion chamber 1x/year use a feeler gauge/vac/stiff nylon brush to really clear out carbon coffee-like grains hook a wet vac up to condensate drain then flush with ~10 gallons of water. After doing this the boiler has run like a top!

"Junk product"
Thought I would save some money and went dual fuel with the Munchkin Contender 120 as the backup. It was well acclaimed by the installer. My mistake for being trustful and not doing more homework. Don't make the same mistake. There is absolutely no comfort that this unit will fire when we do off peak. There are dire consequences during a Minnesota winter. Any details on a class action suit?

"Maintenance NIGHTMARE"
Almost like clockwork the boiler has problems twice a year costing nearly $500 each time. very poor quality and very poorly designed. This piece of equipment should never have been allowed to be on the market.

"Don't Buy!"
We have replaced the blower and the electronics on our unit. Now it looks like we will need to spend even more to fix the latest issue. Pretty soon, we will have spent as much on keeping it running as we did to purchase it. When I called Munchkin, I was told "you can have efficiency or reliability". Wonderful. All the money we save on efficiency we get to spend on replacement parts. Crummy product, crummy company.
