This is the installation of two 98% efficient Lochinvar AWN-151-PM domestic hot water heaters and two 120 gallon ASME storage tanks. This system provides the hot water for a 35 unit apartment building. The old system ran off of the oil fired building heat boiler. This boiler which had to run all summer kept the apartments around and above the boiler room nice and warm all summer long, UGHHHHHH, and used an amazing 17 gallon per hour of heating oil! The fuel cost saving, cash rebates, quiet operation, and building comfort will be welcome relief.
