    Have a weil McClain CGM 6 from 1962. May need to replace it . Is this a match for the one I have?

      According to the manufacturer, CG boilers were first produced in 1967. The CG would have been around 80% efficient back then. GV boilers are 87% efficient. The net output of a CGM-6 was 104,300 BTUH. The GV-6 net output is 133,000 BTUHnet. The GV-5 net output is 105,000 BTUH, which is closer to the CGM-6.

    I own an old home and currenlty have a Weil Mclain HE series boiler. I want to mimick the same for another old home that I just purchased for the water filled radiators, hoter water maker and a radiant heat floor. I would assume that each of these would be considered separate zones. Will the GV-6 unit serve my purpose? If so how is that done?

      Yes, the GV-6 would work, it is similar to the HE series but an updated model. Installation can get complicated so you should consult your installer on how to properly connect the boiler to the different zones.
