@ February 13, 2005 2:49 PM in Indirect versus gas fired WHJerry, So I guess that comparing the combustion efficiency of a gas water heater versus the efficiency of the boiler connected to the indirect and combining this with your method of heating them both to say 140 to get the standby loss -may not be the perfict method but sounds like it would be in the ballpark. Thanks, Ed
@ February 13, 2005 2:42 PM in Indirect versus gas fired WHConstantin, Thanks for the reply. As you probably are aware "gas networks" in MA. is giving out rebates on indirects for$300. Was just wondering about efficiency Thanks, Ed
@ February 13, 2005 12:19 PM in Indirect versus gas fired WHAny information available on the efficiency of indirect domestic hot water versus a standard gas fired water heater? Obviously depends on the efficiency of the boiler the indirect is connected to versus the efficiency of the water heater. But are there other issues to consider??? Thanks for the help Ed
@ February 13, 2005 11:40 AM in Any predictionsSome EXCELLANT points made by all so I won't bother to put my 2 cents in. We are energy pigs in this country. How do we convince customers that this is important?? I quoted a commercial job a few years back in a factory that had a room for storage of potentially flamable chemicals.The job designed by an engineer had an outdoor air handler with a hot water coil (glycol) and non sparking fan wheels to supply heat to the space. And exhaust fans on the roof moving the same cfm. WHAT A WASTE this was an $80,000 job (there was other work involved) I recomended a pipe type air to air heat exchanger in place of the exhaust fans to remove the "polluted" air and bring in outside air. Not as efficient as the wheel types but the air streams could not touch. It would recover 50% of the exhausted heat! It only added $20,000 to the job and they wouldn't do it-even though it would have paid itself off in a couple of years.
