CC-125 96,000 BTU Output Challenger Combo Boiler - Space Heating & Domestic Hot Water

We just had this installed by our local service company Seymour energy services and boy is this thing awesome. The installers came in and installed this thing and it looks great. One tip, this thing is super quiet. Its on you can feel some of the air coming out of it. Overall so far so goodl

This product is the same as BMW 7 series which you can enjoy riding it. However, you have to have son in law or nephew so that you can call every time it breaks. It is troublesome and crazy to have it. it is not like the Japanese Lexus or Honda going to repair shops for oil change and brake job once in a couple years.

Ok, I have had this boiler for a year...see my other reviews here. All I have is praise so far for this boiler. I did resolve a problem of short cycling described in my second review. I did this by adding an 80 gallon buffer tank. It is a 80 gallon water heater that I put inline so that all water mixes with the water in the tank. A smaller tank would have worked fine, but I got a used one in nice shape really cheap. I removed the heating elements and piped in my water with 1" piping, something else that helped things run better. Now I run a larger amount of water through the boiler. This accomplished 2 things for me...first the water that starts to circulate is already warm. No more hot and cold water circulating through the radiators. What I mean by this is the cold water in the pipes is pushed by the hot and takes a few minutes for all of the water to get to the same temp. With the buffer tank all I get is a steady rise in heat. Used to be able to feel the radiators get warm, then cold then warm, then less cold each pass of the boiler. Tested the system this morning...46 degrees here. I was amazed at how much better things heated up. Not looking forward to winter, but looking forward to a good test of the system. Finally the boiler actually makes it to high fire when several circulators are running, something it rarely did before. Still loving it. Natural gas hookup coming next year which will be nice, running propane now which costs more.

Heats my 2200 sq ft tri level . But not without issues. In its first winter it just randomly stopped. Woke up in morning to a freezing house. Reset and worked just fine.the rest of the winter and the next. Now the direct hot water is another story. The flow switch sticks but thats not even a hugr problem . today my ch sensor died . normally not a big deal either. Lets face it things break. The huge deal is that it will take 2to3 weeks to get a new one. Its a simple thermistor. All boilers have them. If it were winter I would be forced to buy a whole new boiler. Product support at triangle tube is a joke.

I have been running my Challeneger Boiler since September of this year, without problems, but had to make some changes. The first thing I want to address is the Domestic Hot Water {Instantaneous} well, all I can say is don't buy the combi if like me, there are lots of points of use (4bathrooms)The reason being, every time someone cracks a hot water faucet, the boiler instantly drops from heat mode to hot water mode, so say I wash my hands real quick, the boiler stops heating and starts heating hot water. It takes 5-10 seconds to switch over, then a bit more to get up to temp unless you set it to remain warm, which defeats the instant hot water benefits. So I wash my hands, somebody is in one of the three showers, or washing thier hands or doing laundry, the heat may be off some time, and if its below zero...well you get the picture. Thats the only thing I don't like about it. I put in an indirect tank heater. Also, because my zones are broken down to so many small zones (9)the boiler seems to short cycle more than I would like. I think I could have gotten away with a unit half the size, after all, how often are multiple zones on all at one time. Not much here, I have been watching this system closely. Still love how quite the boiler is, and it heats my house and two apartments. The tenants regulate thier heat, and the boiler heats thier water as well as ours, total of 6 full time residents with no problems. One other concern I have is, what if it breaks down? Noone around here carries parts, so hopefully it doesn't quit. I have portable propane heaters in case it should happen. Still haven't tried it on the generator to see how it works yet, something I should do. Overall, love it so far. Too early to judge fuel savings, but appears to be lower. will follow up in a couple months. I would give it a 4.5 star rating if I could. 5 stars if it continued to heat and supply DHW at the same time, it has the power to do both.

I bought the Combi boiler (cc125), it was easy to install, easy to convert from NG to LP, the outdoor reset is awesome, heats quickly and watching the temperature modulation in real time was too cool. Set up of the parameters for outdoor temp limits was easy after reading through the instructions. Supposed to be getting NG in town next year, so replacing the old inefficient oil hog boiler with this boiler was an easy decision. And talk about quiet!...no more hearing the rumble of the aforementioned oil hog. Haven't really tested the DHW feature, but it has to save me a bundle as I feed hot water to a one and a two bedroom apartment as well as my house, paying for electric to do so. Looking forward to lower utilities all around. Originally wanted the Buderus or Viessman, but this is bang for the buck, no regrets yet.

Im not a heating and cooling guy , just a jack of all trades, and this boiler was an easy install,used as boiler and direct hot water. works alot better than i expected, keeps my 1970s 2400 sq ft. tri-level nice and warm. had for a year and no problems except for nonstop hot water and cant get the wife to stop taking long showers.just b sure to plan out the exhaust/intake and order all parts together.
