I've received a few quotes and the products are all over the map. How do I determine which are the best products?
If I want to purchase a combi heat and water, does a Weil-McLain (GV90+) offer water? How does it compare with IBC wall hung high efficiency unit? One is rated at 95 the other at 92. In reality, how much savings will I see between the two?
Also any advice on my purchasing the unit vs the contractor. It seems contractors like to add a hefty upcharge. It is a nice gig if you can get it but I'm not too keen on paying significantly more for the same unit. If I can find a contractor to install a unit I buy (unsure about this), what certification should I look for to make certain the installer can actually install a gas boiler meeting all quality standards?
Finally, any propane boiler brands I should focus on - or avoid?
