The one I saw for the house had 2.5 as a minimum just to make the thing light up. I would hope it would keep running if you slowed the flow down say in a sink where you don't need that much water blasting through at a constant rate. ----- Original Message ----- From: Michael Baldwin To: blindhandyman@yahoogroups.com Sent: Sunday, March 23, 2008 8:34 AM Subject: RE: [BlindHandyMan] Why Choose a Tankless Water Heater?
2.5 GPM is what a standard shower head flows at....The turn on flow rate is much less then this. Each manufacture will have a little different flow rate requirements. the one I looked at could handle three things demanding hot water at once. It was 7.6-8.0 GPM max flow rate give or take.

The only ones I've seen have been gas powered. One safety/economy feature that I haven't decided if I like is the minimum flow rate before it will fire. They have or let's say some have, so we don't get out of hand here, some have a minimum of 2.5 gallons per minute flow rate before they will fire. I'm guessing this is so a dripping faucet won't keep the heater running all the time. But you have to turn on a pretty good blast to reach 2.5 gallons per minute. I've really only seen them in a commercial setting before. I know they are getting more popular in houses I just haven't been around any in the house yet. The commercial ones I saw worked in a restaurant and were strong enough to keep their dish washer running with water at 160 degrees F. Pretty impressive recovery rate. ----- Original Message ----- From: [EMAIL PROTECTED] <mailto:spiro%40netaxs.com> com To: blindhandyman@ <mailto:blindhandyman%40yahoogroups.com> yahoogroups.com Sent: Saturday, March 22, 2008 11:57 PM Subject: Re: [BlindHandyMan] Why Choose a Tankless Water Heater? Okay, in the described package, there must be a super heating system. Are they all electric? if not, do they use super thin, and thin walled tubing? I can imagine the water flow for a shoer could overwhelm a unit without tricks up it's sleeving. How do they work? How about for filling a bathtub? Would a house have one for each bathroom, and then general purposes a larger one?
