I am going to be putting in an electric boiler for a customer but I have never had any experience with one.

Has anyone out there ever installed one of these?
I know Burnham has a better reputation than Seisco but any recommendations?

Burnham is made from Cast Iron where as Seisco is made from a plastic poymer.

Electrical requirements are similar. 6/3 with a 50 amp breaker.

Any past experiences.

The boiler will be used for a heating loop in an attached cottage. Possible down the road, an indirect hot water heater will be added.

A Burnham is around $1700 whereas a Seisco is around $1000.
