the big picture

I am looking for a gas fired hot water heat/ domestic hot water system to put into a home in a mild climate in france.

I have recieved estimates from local plumbers using systems which are quite different.

1. the first system is a cast iorn boiler with indirect hot water tank from buderus a german maker. (I know this type of system well)

2. Other systems include instant hot water systems used either with or without copper indirect tanks of about 40 gallons or more. These are in boxes usually wall mounted

3. The 3rd type of system available - but one not yet reccomeded to me is an "accumulator" system. It kinda looks like a typical hot water tank or a small ice box.

Does anyone know the advantages or disatvantages of using these competitive systems. It appears that the 2nd type does everything the cast iorn system does but cost less to run - in short tecknologically superior. But if this is the case why aren't we using it here in good old USA?

thanks,

John Gatti
