These are the standard in Europe and I wanted to make the swap, but there are install issues to be considered:the gas line to the unit needs to be changed to 1" dia all the way to the meter as tankless systems are high btu outputs and need more fuel for the short period theye're active.this creates havoc for the grounds or driveways the line runs under AND a mess for the interior walls.I decided that was too much for me and just r/r the heater with an equivalent

@Kevin Dias - I recommend Gasdick Stanton & Early.

It takes about 2 hours to get to Breckenridge from DIA, without snow or traffic.

Que tengan un lindo dia! 

Honestly I'd much rather see them get their financing and/or tax incentives and/or DIA grants over any of the other potential large-scale downtown area projects (Shipyards, Healthytown, Landing redevelopment), as the Laura Trio impact would be far more effective per dollar than any of the others. 

Ppty tax in most big cities (SAT, DIA, IAH, AUS) runs about 3%!

Día Tres...D...Construct is done....

The main reason for cutting the trees was one large one (6' diameter) that had branches about (1 1/2' in dia) growing over our home.

I'm a retired AF guy and also retired DIA, so the proximity to the Navy base for amenities is nice too.

Bom dia, I hope all is well with you.
