Need Humidifier ASAP, 2+ problems


Hello!

Need a humidifier ASAP, but have two maybe three problems. I am using a heat pump, bypass recommends using hot water as a result. Problem 1.

I have tankless water heater, humidifier will not flow at a rate high enough to get hot water Problem 2.

Already have an Aprilaire 8870 thermostat programmed to run humidifier. Problem 3.

Is Aprilaire 800 steam my only option? Any other recommendations?

--Chris

You can run any brand of humidifier on there you want,its basically a pad /a valve /humidistat and some 6" single wall pipe youre installing no matter what the brand name is.
You can buy them at any box store
As far as the plumbing id try it with your cold water supply line and see how it works

Do NOT hook up ANY humidifier to your HOT water.....always use Cold water, Unless its a steam humidifier. Warm water will only promote the growth of things you don't want to be in you duct system. Here is one more sensible aspect to consider.......you have a high efficiency furnace, and now a state of the art humidification system attached to your furnace, if its being supplied by the hot water tank or a hot water line that is fed from your household HWT then every time the humidifier run, so will you hwt, wasting money to heat water for a humidifier. Why is this wasteful?

Its simple, the water being supplied to the humidifier will be passing through the furnace heat exchanger, it will along with the air it is mixed with be heated by the heat exchanger. So using hot water and burning gas to heat that water in the HWT is wasteful and redundant.

Aprilaire requires a hot water supply.

You can't get a a bypass humidifier work reliable or at all because the HP dsupply air is not hot enough. Most humidifiers have a design temp of 120*F. A few are even rated at 160*F.

And correct me if I am wrong, but I think as the ODA drops so does the HP supply temp. So that leaves evaporative humidifiers out.

Great...

Aprilaire 800 is expensive and this forum is showing mixed results with TruSteam units. I have two heat pumps to make it even worse. I have to figure out a way to use the 850 fan pack and mount centrally.

Measure the humidity when it's around 30* or lower and then tell me how good it is.

Running supplemental heat does not count.
