Hello, I am otw to purchase a 1975 HiLo 2175. Thanks in advance for the insight and help, its greatly appreciated as nothing beats experience.
The first question I have is does this model have a city water xi neutron or hot water heater? The safer doesn't know and the manual I found doesn't provide this information

My guess is that it would have a water heater. Use the buyers check list when considering a HiLo purchase.
