Hello all,

My heating contractor recommends the Baxi Luna Combi boiler @ 87% efficiency. Can someone tell me if Baxi is a good company (reliability) and if they would recommend it? Could someone also tell me what other brand manufacture a combination boiler (ie: 2 independent systems, one for domestice water and the other one for radiant heating (glycol))? Also, I am looking at direct vent (sealed combustion) to be installed in a "air tight" home.

Thank you for any help you can provide,

Thank you very much for your help. I did some reading on the Well Mclain Ultra but it doesn't seems to be a "combination" boiler. I thought that a combination boiler had two distinct loops: one to be used for domestic hot water (water) and another one for heating (glycol for example which would always give priority to the domestic water?

Also, they offer 15 years on cast aluminium boilers but offer lifetime on their cast iron boiler. Should I be looking for a cast iron one instead?

And a last question, is it true that glycol will "gum" the inside of the boiler and that it is not recommended to use glycol for a boiler?

Thanks a million,

I have been trying to find a distributor who can sell the Ultra (weil mclain) in Canada. None of them have the Ultra in their price list. Are there any similar boilers out there with a 94%+ efficiency with as good of a reputation as Weil McLain?

Thanks again for your help,

The Baxi Luna is a great combination boiler in my opinion, however there are some new names coming out right now, check out for some of the cutting edge technology.
