Gennaro: If gas is available install one or two Rinnai tankless heaters; if electric use at least one commercial Accutemp tankless heater designed to handle large space-heating loads. If you want to use one heater, see configuration in Fig. 2 in Rocky Mountain Institute’s Home Energy Brief #5 "Water Heating" (2004).
Happy Holidays,Carmine
