Overview
The Sowyer family from Clinton, CT was having issues with their existing 25 year old boiler system. Knowing that winter was approaching, the Sowyers knew something had to be remedied as their comfort was in question. The boiler was no longer supplying proper heat throughout their home and it wasn’t 100% operational. They knew that an oil boiler replacement might be needed and they called the professionals at Wilcox Energy to remedy the problem. We dispatched Kevin, one of Wilcox Energy’s expert technicians to inspect the oil heating system. After inspecting the existing boiler system, Kevin concluded that the Burnham boiler had reached the end of its lifespan and needed to be replaced.
Problem:
The existing heating system was a 25 year-old Burnham boiler with an internal coil supplying 5 heating zones. The Sowyer family was looking to replace their system with a more efficient option. Even with the system being very well maintained, the Sowyer’s boiler was no longer operating at full efficiency. They wanted to improve their overall home comfort while saving money on their monthly heating costs.
Solution:
Wilcox Energy installed a new oil-fired Buderus boiler with 6 zones. This new system consisted of an Amtrol indirect water heater, a Riello oil burner, and zone valves with IFC circulators. This new system improved the overall home comfort, reduced the monthly operating expenses and increased the value of the Sowyer’s home.

Inconveniences Of An Old Boiler System
Older boiler home heating systems can cause major headaches for homeowners like our Sowyer family in Clinton, Connecticut. Between costing more to heat your home to constant repairs, older heating systems should be replaced when issues keep popping up. New boilers are more efficient and help save money in fuel costs.
Some of the issues that will let you know that your heating system is in need of an upgrade or replacement are:
- Making Strange Noises
- Uneven Heating Throughout Your Home
- Energy Bills Are Higher Than Usual
- Frequent Repairs
- Takes Longer To Heat Up
- Flame Is Yellow And Produces Soot
- Leaks
Peace Of Mind
When upgrading or replacing your older boiler heating system, you will see savings monthly in fuel costs instead of spending more to heat your home. Along with newer home heating systems being quieter, they can keep all of your rooms a constant temperature, so no more worrying that certain rooms will be cooler than others. You can expect a Buderus G115/5 to last for years delivering you the best in boiler technology, for the comfort of your home.
Are New Oil Boilers More Efficient?
New Oil boiler heating systems have an efficiency rating between 80-90% AFUE. With older systems, they could be as low as 60% efficient. That is a major difference in how effective the unit is able to convert fuel into heat energy, costing a lot more in fuel expenses as they can waste 20-30% more fuel. New boiler systems are designed to get the most out of the fuel being used to heat your home. Newer technology is implemented to replace outdated parts in older boilers to keep efficiencies higher longer.
Do Boilers Lose Efficiency With Age?
The quick answer is yes. Over time, as with almost everything, breakdowns will happen. Build up of oil, soot, sludge in the lines, and corrosion will occur. Even with a heating system being maintained annually, it will drop in efficiency as it ages upwards of 15-20 years.
Do I Need Routine Maintenance For My Oil Boiler?
Yes. With routine maintenance, you are making a small investment in your boiler every year to keep it running for an extended amount of years. This maintenance will keep efficiencies as high as possible, lower energy costs and potentially stop costly repairs. By not performing annual maintenance, you allow sludge to build up, run the risk of breakdowns, and are more likely to ensure higher energy bills.
