Hello:
Will be going for a new hot water heater soon. For a residence. The typical cylindrical type independent of the furnace.
Regarding those new gas fired water heaters with the Piezo ignition:
Do they work in a house power outage, such as in a storm ? We lose power often, and would sure like to have, at least, hot water.
Thanks, B.
Time for a little education. Check the link to see what piezoelectricity is.
And how do you apply the pressure to ignite the water heater? I am guessing that it is NOT piezo, but simply an electronic ignition, which will not ignite unless there is electricity. Otherwise it has an extra feature that allows you to ignite the pilot without a match or lighter. One thing to remember is that the pilot also keeps the water hot and prevents you from having to ignite the burner to reheat the water as it gets cold. I have our water heater set at the temp that the pilot holds the water at and have sufficient hot water except when 2 of us are taking long showers at the same time. I really need to get a bigger tank with two of us working dirty jobs and getting home at the same time : 0
No they won't work. Further if the the heater has any type of electric ignition it may/probably will also have an induction fan. So if you lose power often, be sure you buy a lower efficiency rated heater, which has a regular pilot light and no inductor fan. The difference in heater efficiency will be largely unnoticeable and you heater will continue to work when the power goes out.
A Bosch tankless uses 2 D cells for its piezo ignition, they also have a model with a mini hydro generator that produces electricity for its ignition, I have the unit with batteries it works fine.
