Eli: If you are using stream water, make sure the flow-switch will not be fouled or jammed by small debris. Also, with no drainwater heat recovery system -- which everyone on this Forum hates -- you will need approximately 1/3 x 65 = 22<font style="font-size: 8pt;" size="1">1/3</font> kW @ for shower flow rates near 2<font style="font-size: 8pt;" size="1">1/4 <font style="font-size: 10pt;" size="2">GPM; half that @ 1<font style="font-size: 8pt;" size="1">1/8</font> GPM.<br>Carmine<br></font></font><div><div><div><span class="ecxApple-style-span" style="border-collapse: separate; color: rgb(0, 0, 0); font-family: Helvetica; font-size: 12px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px;"><span class="ecxApple-style-span" style="border-collapse: separate; color: rgb(0, 0, 0); font-family: Helvetica; font-size: 12px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px;"></span><br class="ecxApple-interchange-newline"></span> </div><br><div><div>On Feb 2, 2011, at 12:59 PM, elitalking wrote:</div><br class="ecxApple-interchange-newline"><blockquote> <div><font face="Arial" size="2">Can you recommend a brand of electric tankless heater. I am looking to be able to get 120F. I could probably make due with less. This would not allow me to mix cold creek water during draught conditions. Therefore, I would need to use only cistern water. The ambient water temp is 55F. To get to 120, I need a rise of 65F. I suppose I could slow the flow rate to get a higher temperature.

More compact than any tank so you can put it somewhere convenient and it would eliminate virtually all the unavoidable standby losses associated with a tank? <div><br></div> <div>Regards,<br> <div><span style="text-transform: none; text-indent: 0px; border-collapse: separate; font: 12px Helvetica; white-space: normal; letter-spacing: normal; color: rgb(0, 0, 0); word-spacing: 0px;" class="ecxApple-style-span"> <div style="word-wrap: break-word;"><span style="text-transform: none; text-indent: 0px; border-collapse: separate; font: 12px Helvetica; white-space: normal; letter-spacing: normal; color: rgb(0, 0, 0); word-spacing: 0px;" class="ecxApple-style-span"> <div style="word-wrap: break-word;"><span style="text-transform: none; text-indent: 0px; border-collapse: separate; font: 12px Helvetica; white-space: normal; letter-spacing: normal; color: rgb(0, 0, 0); word-spacing: 0px;" class="ecxApple-style-span"> <div style="word-wrap: break-word;"><span style="text-transform: none; text-indent: 0px; border-collapse: separate; font: 12px Helvetica; white-space: normal; letter-spacing: normal; color: rgb(0, 0, 0); word-spacing: 0px;" class="ecxApple-style-span"> <div style="word-wrap: break-word;"> <div> <div style="font: 12px Papyrus; color: rgb(255, 160, 18);"> <div style="font: 12px Papyrus; color: rgb(99, 10, 255);"><span style="font-size: 18px;" class="ecxApple-style-span">Steve Satow</span></div> <div style="font: 12px Papyrus; color: rgb(99, 10, 255);"><br></div> <div style="font: 12px Papyrus; color: rgb(99, 10, 255);"><a href="http://www.naturalbuildingsite.net" target="_blank">www.naturalbuildingsite.net</a></div> <div style="font: 12px Papyrus; color: rgb(99, 10, 255);"><a href="mailto:naturalbuilding@shaw.ca">naturalbuilding@shaw.ca</a></div></div></div></div></span></div></span></div></span></div></span></div><br></div></blockquote></blockquote></div></div></div> </body>
