Re: Steam/Hydronic Combination Boilers?

It helps -- as always -- to have a heating professional who knows what they are doing to do the installation.

I wouldn't say always...

Re: EPA test?

I just realized I took my first 609 21 years ago in 03.

I guess I'm old too.

Hi Mez,
I am having exact same issue. Did you figure out the solution?
My laars boiler is only 2 ys old. The system gets locked out(shutdown) with error code 44 every morning (twice daily when temp <35F) and i need to manually restart it again. My plumber made 7-8 visits but hasnt been able to figure out. We have replaced Air pressure sensor(APS), and main controller board last year and again this year still the same issue has started to reoccur. Already replaced APS this year again but no luck.
