Tweaking high efficiency heating equipment.
March 15, 2017
The residential high efficiency heating equipment found in new homes today require proper commissioning and setup. Often in the past, furnaces, boilers, unit heaters and domestic hot water heating equipment were installed with little emphasis on proper combustion analysis and calibration.
High efficiency condensing furnaces and boilers were designed with reliability and efficiency in mind. For both to happen, the heating system must be correctly installed and commissioned as per the manufacturer specifications after installation.
Adjustments to the high efficiency heating equipment fuel/air ratio allows the heating service technician to setup the correct combustion parameters on all heating equipment installations. Equipment service life and warranty entitlements would depend on correct commissioning and a clean combustion process.
Annual service and maintenance on high efficiency heating and cooling systems is highly recommended. Annual heating system service would include a gas train inspection, operational checks, a visual inspection of the combustion process and filter changes as needed. A proactive rather than a reactive approach to hvac systems maintenance is most cost effective in the long term.
Further tweaking of existing residential hydronic heating systems would include boiler system pumps. Older boiler pumps were typically fixed or multiple speed pumps, having a fixed and constant operating curve. Upgrading the old wet rotor circulation pumps common on all boiler systems to a high efficiency circulator similar to the Armstrong Compass series of high efficiency wet rotor pumps.
