OK, to heat a total of 40 gallons of water like liquid from 50 to boiling in one hour will take about 54K BTU/hr. Using the steam table at 15 psig you get about 945 BTU/lb of steam so you will need a little under 60 lb/hr of steam for the load. Then you have heat losses and other variables, so we always recommend to way oversize these small electric boilers... if you use more steam than you make you get none!
A 30 KW boiler will give you 90 lb/hr of steam and this seems about the right size. Since I am the rep for a manufacturer of electric boilers (SUSSMAN ELECTRIC), look at:
