Arrived onsite for issues with heating system. Homeowner is hearing the boiler click on and off constantly. Performed diagnostic. Had all thermostat turned on. Confirmed operation of the boiler. Confirmed operation of each zone. Boiler turned fired up and shut down at 180 degrees as designed and then came back on at 160 degrees as designed. All zone heated. All baseboard heated. Concluded that second floor bedrooms above garage may have had a frozen pipe stopping the flow of water. Homeowner will continue to observe that zone. Note the water heater is not providing the same about if hot water as it did in the past. Noted during maintenance they the water heater is past the age of replacement and should be replaced. Recommend on demand water heating system. Also, discussed the renovation to the shore house. Recommend adding in demand water heater there and recommend upgrading to heat pump system.
