Behalf Of<BR>Frank Tettemer<BR><BR><FONT face="Courier New"><EM>I can't vouch
for Nick's idea that they only manufacture 13KW tank-less<BR>hot water
heaters. I think that the manufacturers would certainly<BR>provide
electric tank-less heaters of all electrical load sizes, simply<BR>because there
would be a demand for lighter-duty models, and Somebody is going to fill that
market.</EM><BR><BR>I didn't say they only manufacture 13 kW tankless heaters, I
said "Even a small instant electric will take about 13kW"<BR><BR>In responding
to another poster I noted that the smallest offered by a manufacturer for use in
apartments with a single shower was also about 13 kW, and that was unsurprising.
A tankless HWS for family use would typically be about twice that - with
attendant supply problems increasing proportionately - and the manufacturer
alluded to does supply them.<BR><BR><BR></FONT><FONT face="Courier New"><EM>That
doesn't mean that a light-weight tank-less heater would provide
a<BR>satisfactory supply of hot water. <BR></EM><BR><BR>Indeed, which led
me to question somebody using a 9.5 kW heater for his shower. Our old original
13.5 kW wasn't really up to the job around here in winter, and some participants
in this forum live in Canada. <BR><BR><BR></FONT><FONT
face="Courier New"><EM>What I do think is entirely wrong,<BR>is the idea that an
electric hot water heater, of any make or model,<BR>could possibly be considered
environmentally friendly. It's just way<BR>too big of a stretch in
reality.<BR></EM><BR><BR>Agreed. As I said, electric storage and tankless
heaters are banned from new residential construction in most if not all states
of Australia. I'm sure there is no need to explain that to you, and I guess
there is no point in trying to explain it to Carmine!<BR><BR><BR></FONT><FONT
face="Courier New"><EM>Yes, Carmine, if we only look at the almighty dollar, and
compare costs<BR>of various methods of heating domestic hot water, or heating
hot water<BR>for distribution into household heating, the electric devices all
end up costing less to purchase and to operate, in the initial
assessment.</EM><BR><BR>Nick Pyner<BR><BR>Dee Why Beach
