Hello to all,
I have a customer that was thinking about a whole house instant hot water heater. I did some research and looked at the bosch and SEISCO units. The customer wants the electric unit not the gas unit. The thing that concerns me is that both units require 3 40 amp 220 circuits. The customer has a 200 amp service. The main panel is filled except for 4 slots with all 220 breaker for electric heat and includes a 100 breaker for one sub panel and one 60 amp for a second sub panel. I just feel that there is too much on the panel to add this type of devise. Has anyone ever used this type of heater and if so i would like some comments
thanks for the help
