10 hours ago10 hr Good day.Alva 14L Gas Water Heater | Electric | Fan Forced I purchased the abovementioned Water heater for a Flatlet on my property.I am planning to install it in series with an existing 100lt electrical water heater. I have a solar/inverter system which feeds the Electrical heater. In Winter I do not generate enough solar power for the Electric heater and plan to use the newly purchased Alva Gas heater as a booster on cloudy days.My idea is to feed the Alva heater from the Hot water outlet of the Electric heater and then feed the house from the hot water outlet of the Gas heater. See picMy questions are:Can this be done?Can the Alva Gas heater handle incoming hot water?What temperature should the two different heaters be set at? Much appreciated.

Will it blow up, probably only if you go from 0 to 75 degrees inlet water quickly. I don't have the manual, but check if there are high inlet temperature trips. Otherwise you must devise an electric cut-out for the gas heater if the electric geyser temperature is too high.
