We bought a paloma @ Home Depot a little over 2 yrs. ago. Nothing but trouble with this. Customer service really doesn’t want to know much. Blame myself for not doing a little more home work on this brand. Service man out here at least once every two months. Advise anyone who is thinking of buying this brand to talk with someone who has one.

Nothing but problems with our Navien Tankless. Company has a problem with Public Relations. All work done by licensed plumbers. Which has cost a small fortune.

anything come of your class action. I am in Idaho and sure would like to see someway to recoup[ monies spent for an unreliable source of hot water.

We live in the northern Piedmont/triangle of North Carolina and are considering a tankless water heater for our 2400 sq foot ranch style home. We need it for baths/showers and washing some linens. There are 3 of us in our home occasionally a 4th on weekends here and there. We are total electric. Des anyone have a reccomendation for a particular brand. What is the difference between “point of use” and say 4 gpm tankless water heaters?

Yes, but only certain electric ones. You’ll need one that senses the incoming water temperature and adjusts accordingly. I know SEISCO and Stiebel Eltron units operate that way.

You probably also need a pressure reservoir.

As far as the size, you’ll have to figure that out based on your heating demands. I’d imagine too big would be better than too small, the only thing you’d lose is purchase price.

Can a tankless heater be used for radiant heat in a three car garage (approx. 1200″ of 5/8 pex tubing) and if so what size would be recommended. The line is filled with anti-freeze so would be a closed system with return back to the tankless heater. Has anybody tried this sort of thing?

I live in a 2 story single family home. It is time now for me to replace my gas-fired water heater and I am still debating whether to buy a tankless one. I do not know much about this system. Can anyone please email me if it is feasible, economical, and efficient to replace the gas heater with a tankless heater. Would I have to do any retrofits? I would appreciate a quick response, ideally from someone in Souther California using tankless system.

I have a 2 family home that will be fully rented. I am redoing the entire heating system without a chimney. Have placed radiant heating lines in the newly poured basement slab. Each unit, a 2 bedroms apt downstairs and 3 bedroom apt upstairs, will have their own separate meters for gas & electric.
I am serious about placing solar on the roof. I am considering solar thermal to go into a heat exchanger that will then feed into each of the two apt’s separate tankless water heaters to provide an initial boost to the water temperature.
Should the tankless units be gas or electric? I have read conflicting articles on the internet as to which is better to purchase. SEISCO has been mentioned as a good source for an electric tankless. Takagi and Noritz were mentioned on the tankless gas unit side. Can anyone clear up the confusion as to which way to go? Also, for the space heating, the downstairs apt will have radiant heat and upstairs water circulating within radiators. What units would be recommended to heat the water for the space heating and can the solar from the roof handle both the domestic hot water boost as well as the space heating boost at a reasonable installation cost that would be worthwhile?
