[SustainableTompkins] water heating

[Margaret McCasland]

Hi,

I have a version of "on-demand" hot water which is that my domestic 
hot-water (showers, sinks etc) is attached to the hot water boiler 
that heats one wing of the house (a rambling farm house converted to 
4 apartments). A storage tank is attached to an indirect coil that 
heats the domestic hot water. The boiler is a very efficient 
Munchkin. It is on propane.

While the hot water heat is only in three rooms, the domestic hot 
water is used in 4 kitchens, 4 bathrooms, and a shared washing 
machine.  And we never run out of hot water (3 years).  However this 
only makes sense if you're also heating with hot water. You may be 
able to add an indirect coil to an existing boiler if you already 
heat with hot water.

I had just put in a new conventional hot water heater the year 
before, and it was still worth switching to the indirect coil on the 
new boiler I was installing.
