Throwback Thursday: Abington Colonial Needs a New Boiler

PROBLEM: Our homeowners had a twenty-five year old boiler with a bad gas valve. Replacement of the unit was expensive and they decided it'd be wiser to invest in a new boiler as a long-term investment in their comfort and safety.

SOLUTION: ECI Comfort installed a newer version of their Burnham boiler, a series-3 Model #306 gas boiler with electronic ignition. This new boiler is more efficient than the old version and will save on fuel by not running a pilot light constantly. The new control packages can save between 15 and 20 percent in fuel costs.

Throwback Thursday: Cooling An Old City, Philadelphia Row Home With Ductless Air Conditioning

Problem: This row home, built in the 1920's in Old City has a gas-fired water boiler and cast iron radiators for heat, but no central air at all. This means relying on bulky window air conditioners that are a pain to install and take down.

Solution: ECI installed Mitsubishi ducted and ductless mini-split systems. These system doesn't need ductwork to add both air conditioning and heat, so it's a perfect way to solve heating and cooling problems in older homes that lack the extra space for ductwork.

How a Lochinvar Combi Boiler and Mitsubishi Electric Heating and Air Conditioning Transformed This Morrisville, PA Home

PROBLEM: Stephen's new home in Morrisville had a 30-year-old oil boiler and air handler were outdated, inefficient, and costly to operate. The poor ductwork struggled to distribute heat and cool air evenly, leaving parts of the home uncomfortable. Additionally, the oil tank took up valuable basement space, limiting its functionality. 

SOLUTION: ECI Comfort installed a Lochinvar Noble NKC-199 combi boiler, replacing the bulky oil system with an efficient natural gas alternative. A Mitsubishi ducted air handler was added for the main living space, along with three Mitsubishi wall-mounted units for targeted comfort in the basement. This upgrade improved energy efficiency, optimized comfort throughout the home, and freed up basement space for other uses.
