Help with new Hot water heater
We have an old AO Smith 40 gallon gas water heater which seems to have
some leakage issues. We have been anticipating replacing it for some time now but I need some advice. There are five of us in the house (including my 15 year old daughter, who takes very extended showers!) The current unit seems to poop out after 2 or 3 showers and we will not run the dishwasher or washing machine in anticipation of showering. For a new unit, should we go with a larger unit (75 gallon) or are we better off with a smaller 50 or 65 gallon with a faster recovery time? What about the "instant," tankless water heaters? What gives the best performance, balancing efficiency and hot water availability? |

The downside is that the cost of the unit is high and you may need to upgrade your gas line to the meter to support it. The key question is how much more capacity do you need from a conventional unit? If you're only just about running out of capacity on the existing one, I'd go with the 50-65 and look for one that is faster recovery as well. I'd also check the flow rates on showers and change the heads if needed. |

How well do the tankless work in a northeastern climate though?- Hide quoted text - - Show quoted text - It's just a matter of how big of a unit you need, how big of a gas line, and how much you want to spend. There are spec sheets readily available online that show the flow rate vs water temp rise the unit will support. No question gas ones can work, electric is a diff story. |

Of course you could try setting limits and actually directing your
teenager's habits. O, I forgot. It's no longer a parent's right or duty to direct they must just suffer whatever the princess inflicts on them.

Have you looked into adding a unit to the heating systme for heating your hot water? For instance, adding an indirect water heater or booster tank? If your heating system is old you may want to look at the overall picture of both heat and ho****er. Also, you may want to consult your local heating contractor for reccomendations. -paul |

The furnace was just replaced about eight years ago, A/C coil and compressor replaced a year after that. |

I went with a 50 gallon gas-fired conventional water heater and it has served us well. No hot water availability issues in practice, although I suppose in theory it could happen through coincident heavy usage. That is, I wouldn't guarantee that it would never happen, but in practice it has been fine. Your old unit may be limed up and in fact have less capacity than its rating. When my daughter took showers I used to shout through the door, "leave some water for the fishes in the sea." |

I bet dave has a BAD attitude because kids ion his house have stream rolled over him, he takes out the aggression by finding fault here. Now take for instance a home with a 60 amp main breaker. When too many people turn on appliances do you complain too much power is being used? or do the right thing and upgrade to 100 or 200 amp service? In daves world power would be rationed. Turn on hairdryer 4 minutes, now hair dryer off curling iron on 3 minute max, hey want toast OK you have 2 minutes |
