I put in a Rinnai condensing unit awound the beginning of the year. It seems like the gas bill is about half what it was for heating water. It works perfectly.
I put it in the same closet that the old tanked unit was in and added a big filter in the same place.

Is your hot water heating system currently gas or electric?

My house in Miami has three tankless heaters that are produced by a local company. Of course no winters to overcome and the pipes are always warm. I have the largest one on electric power and as long as we don't use the jacuzzi, works very decently.
My bills are lower than who we used the conventional ones. While in Germany I know that this are exclusively the system they use to hear water and they are very cost conscious over there.
The largest unit costs around 400 dollars.
I can only recommend it.

A number of my clients have had my plumber install Rinnai's in Connecticut! The feedback has been 100% positive!

IIRC, I believe the install costs were around $1800 or so...my clients paid the plumber direct. Some of them required certain extras to relocate the tank to the wall away from where the water heater was, etc.

I used to put in quite a few tankless units. I like the Rinnai best overall. Good units, good price, good price on the vent kits, no call backs. Didn't like the Bosch units at all. Stayed away from the Rheem because of the high vent line costs. Rheem however does have some new units out with standard vent lines. Based on experience I would recommend the Rinnai.
If you have kids, whirlpools or use multiple appliances at once these are great units to have. You don't have to worry about 1 person not taking a shower while someone else is. One of the important things to remember is that these are NOT instant hot water units like some people think. Just like a conventional tank, the old cold water in the lines needs to be pushed out first before the hot water reaches you.
If you don't use a lot of appliances at the same time, tankless units aren't all that necessary. A 50-75 gallon unit can do pretty well. One of the forgotten gems of domestic hot water heating is the pre-storage tank but that's a different story.
Depending on who's literature you read, the cost and return on investment for a tankless unit is either good to negligible. I like these units but they aren't necessary for everyone.

No a combi boiler is called that because it heat both heating circuit and hot water. I think these are hot water only

I actually have a unit added onto my heat pump that preheats water and stores it in a tank before my electric hot water heater. In summer time it is free heated water except for the minor cost of the circulation pump.

I got the unit online and if I remember correctly, it was about a grand delivered. I installed it, which wasn't a big deal.
I added a filter because we get some cream colored substance in our municipal water every so often. Not regularly but periodically. I think it's clay and it fouls up plug valves, clogs screens, and other mischief. It seems to be related to the level of Lake Travis, which is the primary source of municipal water. I have friends that live closer to the lake and they have more issues with it than we do. I put a GE whole-house filter on the supply side of the Rinnai to keep it clean as long as possible.
