October is here and heating season is no longer approaching. It has arrived. This month we are focused on the decisions that matter right now: when to repair, when to replace, and how to know the difference before the equipment makes the decision for you. We also have a Viessmann product spotlight, a code update on pump efficiency standards, and three jokes that are only slightly better than last month's. Thanks for reading.

Boiler end of life indicators: when repair stops making sense and replacement is the right answer.
A boiler still producing heat can look like a functioning asset right up until the repair that costs more than the equipment is worth. Repair frequency trending, heat transfer surface condition, refractory wear, and controls obsolescence are the indicators worth tracking now before the equipment forces the decision on its own schedule.
The replacement decision is better made on your schedule than the boiler's. Three years of repair records tells you more about end of life than the nameplate ever will.

Hurst boiler controls and burner management systems: what modern control systems provide and why they matter.
A boiler running on legacy controls may be meeting its heating function while silently accumulating fault history nobody is reviewing and approaching failures a modern system would have flagged months earlier.

Merion Pump
Pump replacement versus repair: the decision framework for commercial hydronic pumps.
Replacing pumps after they fail is the most expensive version of the lifecycle. The repair cost calculation includes what is failing now and what is developing over the next two to three years.

HX Coils
Coil inspection during heating season without taking the system offline.
The pre-season window has closed. Performance trending, airside pressure drop monitoring, infrared thermography, and water chemistry sampling all provide meaningful coil condition information without an outage.

Q
|
Our boiler is 22 years old and still running. We have been repairing it annually for the past three years. At what point should we be having a replacement conversation instead of another repair conversation?
|
|
A
|
You are already in the replacement conversation. You just have not framed it that way yet. Three consecutive years of annual repairs on a 22-year-old boiler is a trend, and trends in repair costs almost always continue in one direction. The question is not whether to have the replacement conversation but how to structure it so it produces a good capital decision rather than a reactive emergency replacement.
Pull the last three years of repair invoices and add them up. Then get a replacement estimate. Compare the projected repair cost over the next three years, which will almost certainly be higher than the previous three, against the amortized cost of a replacement boiler. For most 22-year-old boilers with increasing annual repair costs, that comparison tips toward replacement within a one to three year payback window when the efficiency improvement of a modern boiler is included.
The other consideration is timing. A planned replacement scheduled before a failure gives you control over the specification, the contractor selection, and the installation window. An emergency replacement after a mid-winter failure gives you none of those things. The GP Energy team is happy to work through the repair versus replace analysis with you before the next repair bill arrives.

Code and Standards Update
ASHRAE 90.1
Pump efficiency requirements and what they mean for new commercial hydronic specifications.
ASHRAE Standard 90.1, Energy Standard for Buildings Except Low-Rise Residential Buildings, includes minimum efficiency requirements for pumping systems in commercial buildings. The standard requires that variable speed drives be used on pumps above defined horsepower thresholds in variable flow systems, and that pump motors meet minimum efficiency standards under the applicable motor efficiency regulations.
For engineers specifying commercial hydronic pump systems, ASHRAE 90.1 compliance is increasingly relevant as energy codes in Pennsylvania, New Jersey, Delaware, and Maryland reference 90.1 as the baseline for commercial building energy compliance. A pump specification that does not account for 90.1 variable speed drive requirements or motor efficiency minimums may require revision during the permit review process. EC motor technology in wet rotor circulators, such as the Wilo Stratos series, typically exceeds 90.1 minimum efficiency requirements and supports energy code compliance documentation for LEED and similar certification programs.

From the Field
Heating season is not waiting.
October is the month where deferred maintenance decisions become heating season problems. Equipment that passed the pre-season inspection with notes, components that were flagged but not addressed, boilers running on aging controls that nobody has reviewed. The GP Energy and Merion Pump service teams are in the field now. If there is something on your equipment that has been on the list and has not been addressed, this is the week to make the call.
