The Baxi Luna HT is a modulating, condensing wall-hung gas boiler with an efficiency of up to 92.5% AFUE. One of the five models of the Luna HT, the HT 380, is a combination central heating and on-demand domestic hot water boiler. The nickel-chrome, stainless steel design of the premix burner and primary heat exchanger provide resistance to corrosion and low heat inertia. The unit is approved for closet installation, and the fully modulating fan and direct vent ensure quiet operation. The Luna HT features an electronic, gradual ignition and a gas valve with continuous modulation system. The fully automatic self-diagnostics include a double CPU microprocessor for optimal efficiency. Multiple units can be cascaded to share the same vent with a single exterior opening.
Installed 10 years ago. Worked fine for first year but have had at least 3 or more issues every year since. It's garbage. I can't wait to get rid of it. And yes I have used certified service repair guys. I know them well because they have been to my house many times with a different excuse to why my Baxi doesn't work. I finally started to have my plumber fix it. He's much cheaper and at least makes me laugh when he tells me how awful Baxi's are to work on and how he makes a lot of money fixing them.
Worked well for 2 years and now nothing but problems. I have spent more than $3500 on repairs! The people who installed it no longer service or sell these terrible boilers. Will need a new boiler soon. Avoid at all costs. What a junk! Update: 2017-09-11 Horrible price of equipment-stay way from this. The dealer that recommended to me stopped selling and working on these. It is junk and malfunctions often. No saving here. Too bad
"Stay clear of these."
Nothing but problems from day 1. Baxi won't own up to this bad, bad lemon of a boiler. Thousands of dollars in maintenance and parts negate any possible energy savings. Don't do it. Look elsewhere.
I read a lot of really bad reviews on this unit. My first question is: Was it a Baxi qualified installer that installed the unit, and also the same for problems and repairs? They need to be calibrated and set up right on the initial install. If you're somewhat of a mechanically inclined person, troubleshooting them is fairly easy. If not, then a good Baxi service person should be able to fix it. You need a good Baxi qualified person to deal with this unit; the same goes for most brands that are out there. I have a Baxi ht380 Luna and its been fantastic, the only problem has been my power company gas meter going to crap and having it replaced. I will back this unit up 100% for what it is.
After extensive research, we thought this unit would be the ideal replacement when we converted our home from oil to gas heating. At the beginning, for the first two years, it worked well. We did notice that when temperatures got colder, the pilot light tended to shut itself off. Then we had a problem with the hot water not working. Finally, on the eve of a winter storm, the power light went off and the pilot shut down, and a little leak began beneath the unit. That's when I reached my limit with this equipment. We watched the temperatures plummet inside as we tried to get a qualified technician to help. Anytime we have a problem, we have to call the people who installed it for us and it's an expensive production every time. They act like it's a big favor they are doing us even though they represent the brand. The unit is supposed to be serviced once a year. I can't get anyone to do that. I hate this unreliable thing. I always have to check to make sure the pilot is running and that I don't need to reset it so that I don't leave for the day and return at night to a freezing house. I regret that we bought it. I hope we can replace it before we come home one day to temperatures in the 40's (yes, that cold) and busted pipes. Don't bother with this unit. It's a nightmare. It's temperamental and no one knows how or wants to service it.
Many comments on HVAC forums describe the Luna HT as reliable. Reviewers on several threads on heatinghelp.com describe the unit as reliable and quiet, with several installers saying that installation is clean and easy. A couple of reviewers were not pleased with Baxi’s customer service and website.
