Baxi Luna HT Boiler Overview

The boiler was installed 12/19/12 and a fully functional indirect hot water heater was removed because "it would decrease the efficiency of this Baxi". Approximately six month later I had no hot water and error code E119. A technician advised me how to fix it over the phone and told me the system shut down as a result of "low water" in the system. On a Sunday morning in February we woke up to a cold house and another error code E119. When I tried to fix it the same way as before, water started bubbling out of a valve. I stopped and called Auchinachie, the company that sold and installed the unit. Eight hours later a technician came out. He tightened the valve, recharged the system and E119 went away. Two days later, a technician was sent out to change two valves. On November 5, my wife and I returned from a visit with our children to find a cold house. Another E119. I tried the initial procedure; it worked and E119 went away. I called Auchinachie again and they sent a technician who determined a sensor was faulty. Several days later, he returned and replaced the sensor. We have never been satisfied with having to run the hot water for forty to forty-five seconds before the temperature stabilized and we've never been happy with the fact that turning another faucet on while someone is showering creates a significant change in pressure in the shower. Same thing if the dishwasher kicks in or the clothes washer. We basically have to schedule normal household functions very tightly. I was told yesterday that the system is working "as designed" and we'll probably need to take a little time to acclimate ourselves to the new technology. I was told that an indirect hot water heater just like the one taken out would/should probably get me the comfort back that I enjoyed prior to having the Baxi installed. When I was sold the Baxi I asked for a boiler that was equal to or better than the one I had for over twenty years. I have neither. The title of this piece says it all. It would make a great vacuum cleaner because it really sucks. My considered opinion only. There's a lemon law for cars; too bad there isn't one for boilers.

I have had this HT330 for over 4 years and never had an issue when they were sold by Laars. Once Baxi took over the sales and support, the nightmare began. Get constant E133 codes after switching over from DHW mode to Winter mode and vice-versa. Have literally replaced every sensor, igniter and flame sensor. Now it's Saturday and no response after submitting the absurd online form over 24 hours ago. Still no heat or hot water and no telling when I will hear back. Two HVAC contractors have told me that any Baxi service is a minimum 2 trip affair, at a minimum $260 each visit. I have little choice but to buy a reliable Laars Mascot II with factory phone support. The unit is basically reliable, but Baxi has got to be the most customer unfriendly company I have had the misfortune to get stuck with. Marathon International, the U.S distributor, has a habit of changing support phone numbers often. I have had 2 different support numbers over the last 2 years that I got after talking to several vendors. Now I get "this number is no longer in service" messages.

I am 100% unsatisfied with the way it breaks very often. I had to change the turbine for the 2nd time. I called one company they said $400, the other $500. Turbine measures how many gallons per minute the boiler should give. I have a small house, 1100 first floor, open full basement (which I do not heat in the fall and spring, and 2nd floor of 500 sf. Looks like I need to change the fan piece now. Every time any thing breaks the labor is very expensive. I suggest If you already installed this piece of sh*t you better learn how to change the parts on your own or it will cost you a fortune. Those hot shots that will install for you this boiler, you better get a long term agreement on the service. The parts are not that expensive. I rather change it for a different boiler.
