Anyone installing the HTP Crossover floor water heater?
How does the water heater preform? Enough hot water? Any problems with this unit?

Good unit so far . Have a few installed around , here and there . One in particular on propane at 8,000' in Cotopaxi Colorado is performing so well that the homeowner decided to call me and tell me how good it is .

That’s because it was well installed by a real pro!—NBC

Is 104 the tank temp or do you have a mixing valve?

If you really want to get a good handle on whether a given tankless water heater will be saticfactory in a given setting, it's not hard. For the higher quality ones, check the manufacturer's specifications. They will give you the gallons per minute they can provide vs. the temperature rise. Then look at what your maximum hot water draw will be -- but be realistic, particularly with showers -- they tend to draw more than the rosy ratings suggest.

For lower quality ones, or ones with rave reviews and not much manufacturer provided specifications, you can always use the good old hydronic formula: BTUh = 500 times delta T times gallons per minute. For example, you want to run a shower at 105 F. Incoming water is at 45 F. The shower draws 3 gpm. What BTUh do you need? It's 500 * 60 *3, which comes out to 90,000 BTUh, or 26 kW.

Advertisements and rave reviews are wonderful, but thermodynamics doesn't lie. Less power input than that, and you'll have a cold shower. That 5.5 kW input with a 60 degree rise will give you about 2/3 gallons per minute.
