Just curious if anyone here in the 5 Boroughs has replaced their hot water heater for a tankless unit. I am buying a house in the Bronx with a 13 yo HWH and am contemplating a switch over.

I live in an apartment with one right now, it does both the heat and hot water. I would be looking to do just hot water since the gas boiler is only 3 years old.

I'm curious if its even worth just doing it for the hot water and not both that and heat. Also would like to get an idea on cost and if it's saved anyone any money long term. Thx in advance.

Yes they are worth it, but obviously more expensive and use more gas/electrical energy.

Tankless are more of a luxury item, so if you have $$, go for it.

They are worth it and not very expensive but they need to be vented to the outside of the house.

If you have the gas in place, the chimney in place and your hot water tank is old, tankless is a no brainer. What it saves you is the heat loss 24/7/365 from 50 gallons of hot water sitting in your basement at all times.

(We ARE talking gas here, right?)

Do they work "instant hot water?' Or do you have to run hot water some time before you'll need it in order to get the thing to start heating the water? My current tank "sleeps" overnight. Come morning, you have to run hot water for 10 - 20 minutes before you take a shower. I'm considering switching - mostly just to grab some space to enlarge my bathroom.

Frist of all there is no such thing as a "hot water heater", that term implies you are heating water that is already hot. The correct name for the appliance in question is water heater.

Next as to how much one can save using tankless versus tank there are many variables to consider. However when Consumer Reports and others crunched the numbers normally tankless units came up short, especially those powered by electricity. Gas units are another matter but still often do not quite fulfill their promise.

Are tankless water heaters a worthwhile investment?

Historically most apartment buildings in NYC used steam or hot water heating (fueled by coal later by oil and or gas) with a side arm system to provide hot water. Ditto for many one, two smaller homes. This system provided "free" hot water since you are using the boiler to accomplish two functions.

However many newer apartment buildings are moving heating and or hot water costs onto tenants. You find PTAC units for heating/cooling, central heating/air conditioning and yes tankless hot water systems. These are all very well and good for several reasons but again it again shifts a higher percentage of utility costs to the renter/owner of a unit.
