Rinnai
boilers are limited to 178 degrees Fahrenheit for maximum efficiency. 178
degrees was not high enough to heat the building with the amount of baseboard
installed. We responded by replacing the Rinnai boilers with NTI boilers with a
higher operating temperature of 195 degrees Fahrenheit, at no charge to her,
which solved the under heating problem. We used thier existing system pump as listed in the contract
from 2011. The pump failure [redacted] listed as an issue was a used pump in 2011
when we reinstalled it because it was only several years old.The new NTI boilers have an error history feature which
would tell us if the boilers are operating out of design parameters. The nti
boilers were operating within all there design parameters when installed. There
are many ways to pipe the NTI boilers due to their low pressure drop. The
opinion of other contractors that the boilers are not installed properly can be
easily checked by checking the boiler history which will have dates of any
operation out of design parameters.The boilers are not piped wrong, just different. There are
many ways to achieve the same result when piping low pressure drop boilers.The history will tell us if there is anything wrong with the
boiler flow rate.The pump failure has nothing to do with us it was a used
pump in 2011.September 2011 installed two Rinnai 130,000 btuh boilers
