: I have received conflicting recommendations regarding a hot water heater for heating (radiant under floor) and domestic hot water use. My plumber has advised me that I should use a cast iron furnace with a large storage tank and not a water heater. An oil and gas hot water heater manufacturer suggested oil heat with a large hot water heater with a minimum 100-gallon storage and recovery rate of over 200 gallons p/hour. A radiant heat company suggested gas fuel as preferred promoting a 96% efficient 50-gallon storage with 120-gph recovery and as an oil alternative a Bock unit with a 50-gallon storage and 166-gph recovery. : Facts: : 1) A new home 2,863 sq. ft. : 2) Location: Portland, Maine : 3) Fuel source available either propane, electric or oil. : 4) Radiant heat : 5) Water: 79 PSI : 6) No more than 4 occupants : 7) Standard dishwasher and washing machine : 8) Two and half bathrooms including a master bath with a custom shower and steam room. The shower will have 10 Grohe outlets rated at 2.5 GPM each at 80 PSI. : My question is what fuel and minimum tank storage size/recovery rate will give me sufficient hot water for this house? : Thanks in advance for your help. If you still have questions about your radiant heat,I'M HEATING A 5900 SQ.FT. house with a water heater rated 95+.We have 5 bathrooms a whilepool and 7 people. It heats domestic as well as myhouse on a 50 gal. unit.
