If you're thinking about a tankless water heater, however, you must realize that by definition it will take slightly longer to get hot water at your faucets. Right now hot water starts flowing from your big tank as soon as you open that faucet. With a tankless, the computer kicks in when you open the faucet, the gas flows to the burners, the electronic ignition creates flame, and the water is heated as it passes through the heater.
This heater seems to come on instantaneously when a faucet is opened (with a satisfying whoosh) and hot water reaches our faucets almost as fast as it used to. It may be fractionally slower to get there, but it's endless hot water, at a precise temperature, and those are the two things we didn't have before.
My other suggestion is to make sure you size your tankless properly for your use - this one is perfect for our 2.5 bathroom home. There is a larger one available if you need the extra capacity.
It takes longer to get one installed properly, with the extra venting and the materials required. Don't be part of the learning curve for your installer. Make SURE your installer has experience with tankless installations and ASK FOR REFERENCES. It is a different technology and the installation techniques are different from a traditional water heater.
It is a space saving unit, and extremely quiet. And it can flat crank out the hot water! No lags, no lukewarm spaces, no waiting, just all the hot water you want when you want it! Our gas bill dropped about 15% in a much colder winter - no more water heater constantly running to keep hot water hot, no more shortened showers, and a very happy family.
Also, if you are looking to save on your gas bill with this unit...you won't. I have used this unit for 8 months (same household conditions before and after) and have seen no significant decline in my gas usage. When you consider the cost of installing this unit against a good quality conventional tank water heater, your payback on a tankless unit is quite long...C.R. says 22 years is the average, but I think that is generous. Also consider that tankless units cost far more to install, as special intake and exhaust venting is required. Rinnai uses an innovative 2 in 1 vent system that works very well, but is very expensive and can add significantly to your overall cost, depending on your particular application.
BOTTOM LINE: I bought this unit since I needed to replace my old tank unit and also needed a hot water heater with a small foot print (due to space limitations. I would add the federal energy credit benefit was a huge incentive...without it,I would not likely have purchased the unit. Therefore, unless you have space limitations and/or can benefit from the energy credit, I suggest looking for a good quality conventional tank hot water heater - the newer units of today are very energy efficient and probably a better choice than the tankless until the technology improves beyond present level.Read more ›
