Solar hot water question
We are buying a house that is in rather bad condition. There are some plumbing issues that need to be corrected immediately with a master bathroom remodel. As part of the replumbing we would like to replace the elderly hot water heater. The house has a large, steeply sloped, south-facing roof on which I would like to eventually install a solar water heater. Is it possible to install a solar-compatible water heater separately during the initial part of the remodel? Are there any brands to consider first? We are located in coastal southern California where "cold weather" is anything below 60 degrees F.
