Tankless water Heaters. gas
Whether you are building a new home or retrofiiting an older one (like me), take time to evaluate the hot water system. After all, estimates say that as much as 30% of a home’s energy budget is consumed by heating water.
My new “old house” came complete with an old and rusted gas-fueled tank-style water heater in the attic that was dying… well, dead. The question was not “should it be replaced?” but rather, “should it be replaced with a similar model or a new tankless system?”
A traditional water heater continuously heats water in the tank, regardless of whether it is being used. By comparison, the newer tankless designs heat water only when there is demand for it. Less stored water to heat means less cost—and let’s not forget, a more compact, wall-mounted design.
Size Matters: Tankless hot water heaters are available in room or whole-house sizes. Calculate how many appliances or fixtures need hot water in order to determine the best size unit for your home. For me, a whole-house system was needed.
Fuel Type: Hot water heaters are available in either electric or gas (natural and propane) models. If you are considering electric, check for voltage and amperage requirements. The gas version will need some electric to operate, but venting will be the bigger issue.
Location: If you live further north, your ground water will be colder than if you reside in the southern or western part of the country. The temperature of the water will affect the speed and flow.
Know the Flow: If you think you will need to run the dishwasher while someone else is showering, assume a larger gallons-per-minute (GPM) rate will be on order to meet your overall water needs. Take into account water usage, too: A bathroom needs less water than a kitchen, a dishwasher less than a shower, and so on.
Look into Rebates: Many utility companies offer incentives, and you may benefit from state tax credits as well. Investigate both to ensure that you’re eligible and if so, that you reap the full benefits.
Rinnai gas heater burner goes out when ignition button is released? | Yahoo Answers
I just bought a 2nd hand Rinnai Econoheat 850 gas heater. When I press the control button down, the ignition works fine and burners come on (gas supply present) and start turning bright. But when I release it after holding for 10 seconds, the burner goes off. I have tried ventilating the room, replacing the...
@The Handbuilt City: Does anyone have experience working with tankless water heaters? We do, quite minimally. Looking for some comparison of electric vs. gas.
