I have a Wiel-McLain boiler that was installed in the house when it was built in '66. I have had the burner changed, but I am considering one of those newer high-efficiency units installed, anyone have any experience with them?

I have started my search with Buderus and Munchkin (it's really not that small )

 

i went with a burnham MPO 147 with an indirect tank for the hot water - it's been three years now and no troubles at all

i have FHW

went from 70% to 85% efficiently can

 

oh and it has a life time warranty

 

I wish I could help but I live in heat pump country.

 

here's where i asked my questions

Same here (and I'm quite happy to report that).

 

I'll be watching your results with a keen eye.
I think my issue is more of a controls rather than burner issue though.

 

^ your issue is you have to heat a mansion

 

Thanks, I will give it a look.

 

ken, we replaced our behemoth (probably the original 1920's coal furnace...converted to oil) about 5 years ago....using a Peerless Burner (mf'd Boyertown PA). by coincidence, it just rec'd it's annual maintenance TODAY and is 84% efficient.

when we upgraded to this unit, we added controls and a second circulating pump/ thermosta/ etc to expand from ONE heating zone to TWO....and this has made a world of diff in comfort and economy

option: since you like "electronics" and "gadgets", maybe you should consider going to a groundwater GeoThermal loop system. just the control center would put your A/V home theater racks to shame otoh, with the mini-lake across from your rear yard, you may not have the space to run the piping loop
