This is the best electric boiler I have found for radiant floor heat.
All of these heaters are UL 499 compliant and our processes reviewed and tested by an outside testing agency each quarter and use stainless steel heat exchangers and incoloy sheathed elements with titanium sheathing available
The heat exchangers are made of 304 stainless with other stainless alloys available. Our heating elements sheathing material is 800 incoloy. The warranty on electrical parts is 2 years which to our knowledge is the longest in the industry. Our units now meet the no brass rules that start in 2014 for potable water. Those rules are now in effect in Vermont and California but start in other areas of the US in 2014.
This boiler is specifically built for radiant floor heat.
