Instant hot water heaters
Anyone using one? In place of the regular 6-gallon water heater? Issues? TIA
Forum Discussion
The major differences between the "instant" or "Tankless" and the standard 6 or 10 gallon can are as follows. Aqua Hot and it's competitor are NOT this type of heater.. So this (for the most part) does not apply to them.
The "Instant" jobs do not store hot water. Thy only "Burn" when water is flowing. So at VERY LOW flow rates.. May not kick in.
At more normal rates they work very well.
They only burn fuel, Propane or Diesel) not electricity. Now I do not pay for kilowatt hours.. But I do pay for gallons.
Second: They can USUALLY (-10 perhaps not) heat water faster than you can draw it,, Thus you never run out of hot unless you run out of fuel (Also applies to Aqua Hot and it's competitor).
Next, When it's below frigid out Like 11(f)) I let my heater run all night, all liquid in the AM. no problem. Not sure how that would work with the instant jobs (Does not apply to AquaHot).
I think the best of all worlds would be as follows.
A standard heater for the kitchen and lav's
An "Instant on" for the shower
and a very very low flow circulating pump to keep the hot line to the shower... HOT. (Well warm in cold weather).. not fast enough to fire the burner (Or a manual cut off switch on the burner) but fast enough to prevent freezing.
