Electric Boilers - Which to choose?

sbmfj

Good morning,



Im updating my heating system, and will be installing a electric boilers fro my hotwater gravity / hydronic system. There are 2 units that I am considering, a Hydra Evolution made by Dettson ( <a href="http://www.dettson.ca/En/index.html">http://www.dettson.ca/En/index.html</a> ) or a Slant-Fin Monitron ( <a href="http://www.slantfin.ca/product-monitron-eh.html">http://www.slantfin.ca/product-monitron-eh.html</a> ). Would you guys recommend one over the other? The Slant Fin does mention that its heat exchanger is a one piece cast iron unit, so it will weigh more, but I imagine perhaps last longer? Anyone have experience with either one of these brands or units themselves? Thanks of rany feedback you can provide.



Have a good day.
