I have a Gerrard water heater in my roadtrek Zion I am not happy with it,sometimes it work and sometimes it don't. Wonder if anyone has ever replaced theirs and if so what they replaced it with.
Several Winnebago MH owners have replace their Girard water heaters with a standard tank water heater. In my MH there is room for this exchange. I have seen several members replace but do not remember the cost (~$1K or less). I have used my Girard water heater only a few times (one shower) and find that I need to just use the hot water line only to keep steady temperature. You have to have a good flow of water for it to work and temperature set high enough.
