   gas tankless water heaters cost about 3 x as much as a tank heater if its to be professionally installed…2 main advantages are: [1] they supply continuous hot water,,not just 30 or 40 gallons max at a time.. [2] they arent suppose to rust out/corrode/rupture and need replacement after 12-15 years like a tank would…..disadvantages are:[1] cost…[2] the ones i’ve seen are pretty complex,,in my opinion are likely to need repairs as they age,,the repairs could cost as much as a new tank type heater would cost to have installed [$600-$750],assuming tankless is out of warrenty by then,,i doubt they have longer than 10 year warrenty on parts other than the water coil itself… [3] the energy savings is often exaggerated in my opinion…a tank heater will only cost about $30/month at the most…even if the tankless saves 33% of that [i doubt it even saves that much], thats only $10 per month,or $120 per year savings,,not enough to justify the extra cost in my opinion..by the time it saved you enough to justify the cost,it would probably start costing a lot to repair by then…. so i would only get a tankless if i needed the large supply of hot water they can give [large family,hot tub,etc],,or if you need the extra space the tankless would give you because its smaller than a tank,esp a large tank[50 gal]….i wouldnt do it for energy savings or longevity,,most people dont stay in a house for more than 10-15 years anyway…….dan

   I’d find out if there’s any local dealers for any of the brand names and if there are service people available for that particular brand nearby too. There’s many good brands out there but I’d definitely go with the gas model. I got a 199,000 BTU outdoor unit to avoid having to pay extra for the new vent work that has to be done on the indoor units. It can service multiple taps at the same time, such as two people running bath water while the dishwasher is running. If you get too small of a unit you’ll be down to a trickle if you try that. There’s also a $300 income tax credit if you go with an energy efficient tankless unit versus the old tank type. I’m on propane and our old unit would run around $40 to $45 a month, now it’s down to around $25 to $30.

   Initial cost is about twice that of a 40 gal
   unit. But much more efficient.
