yes - can recommend the rinnai infiti 26 for whole house. they also have POE type which is a lot cheaper (around 500 vs. 1600). infinit 26 is running well for the past 7 yrs for my house. only had to change PB-board this year due to lightning creeping inside (they say - i think it shorted somehow cause i have whole house lightning prorection). added an extra line of protection now just in case they are right. otherwise very good low gas consumption, preset temp as you like it and zero other maintenance costs.
