On Demand Water Heaters

Ciril Wyatt-Donnelly

I have been reading a lot about "On Demand Water Heaters" and I am thinking of purchasing one. Does anybody have any thoughts about whether they are worth their high price tag? Thanks for any input!

Get Hot - Calientese

I have put in a dozen or so of the Takagi TK-1 TK-2 and Mobius units. Gas fired units.

All of my customers have been "more than satisfied" with their preformance.

The fuel savings are unbelievable.

Do'nt expect to run more than 2-3 fixtures at once or the Delta T (temp differential) will drop incrementally as you use more and more hot water.

I recomend installing a shut off and bypass with a couple of hose bibbs at the heater in & outlets because if you have hard water it can and will foul the heat exchanger over time and that means no more nice hot water.
By circulating a chemical such as CLR through the HX for a half an hour or so it will clean it out nicely.

On Demand Hot-water

We sell Rinnai - Continuun on demand hot water makers & I also have one in my own home. My only problem with it is I have endless hot water and I can never get my wife out if the shower after she gets in!

Tankless

Spend the money on the higher end units like those mentioned above. I know someone who installed two lower end heaters and was not very happy this past winter. The incoming water was so cold that the heaters had to throttle the flow to a trickle to maintain the desired output temp. Lowered the setting to get the flow up and showers were still marginal at best.

Be sure to check the specs on delta T and flow rate before you buy.

Tankless hot water heaters.

The only electric one I know that is designed for a "whole-house" application is the SEISCO. Check them out at www.seisco.com

Watts uses them on their pre-assembled radiant control panels.

You can argue efficiency vs. cost to operate all day long (i.e. gas vs. electric), but these units win hands down.

Tankless / instantaneous units

are truly the way of the future. The units mentioned above more than pay back in savings and performance. Some units like the Rinnai can even be mounted outside with built in freeze protection. The only real drawback is that unlike a standing pilot gas storage unit, the instantaneous will not work in a power outtage. Other than that, everyone should seriuosly consider them next time their heater needs replacing.
