"Which is better suited for home use, the electric models or the hydronic models?" Both are for home use. Electric is easier to install and more easily turned
on-and-off. Myson does offer an optional wall timer. Hydronic is used when there is a recirculating system, or there is a steam boiler, or a hot water boiler in the house. Please do note that with
a "closed loop" system, what is recommended to prevent electrolyses leaching failure,
which is induced by high mineral content induced by a recirculating system.
"What is the difference between electric and these hydronic models?" Electric is "electric oil filled". Mineral oil is heated by an electric
element. Hydronic is empty and hot water is circulated through it.
