One of the most common home heating systems in Wisconsin is a boiler, especially in older homes. Boilers heat water and then distribute hot steam or water to rooms through a series of pipes to heat the home. Steam is sent to radiators while hot water flows to radiators or radiant heating systems. New systems are very energy efficient – review the boilers recommended by DG Heating & Cooling below!

What to Consider Before Purchasing a Boiler

Fuel Type

Gas-fueled boilers may cost less to operate than oil-fueled ones if heating oil prices are high. However, the fuel type you choose will depend on what’s locally available.


The boiler’s size is as important as its efficiency. If the boiler is undersized, it won’t work efficiently; if it is oversized, it will cost more to heat a home. At DG Heating & Cooling, we use an Air Conditioning Contractors of America (ACCA) calculation to properly determine the right boiler type and size for your home taking into consideration foundation, wall thicknesses, insulation, windows, air filtration, and more.


Boilers only provide heat, so a secondary air conditioning system will be required to cool a home in the summer months.

Energy Efficiency

Boilers are rated with an annual fuel-utilization-efficiency (AFUE) score, which tells you how much energy is being converted into useable heat. New boilers must have an AFUE rating of at last 80 percent, and high-efficiency models are 90 to 98.5 percent efficient. The higher the rating, the higher the equipment cost, but the lower the overall operating cost.

What Type Of Boiler Do You Have?

Boilers are called “central heating systems” due to the system's central location with heat being spread throughout the home. However, unlike other heating methods, there is typically a lag time between the boiler turning on and the heat being dispersed. Most boilers produce steam or hot water using natural gas or heating oil, and all are either condensing or non-condensing. If you are unsure what type of boiler system your home currently employs, call DG Heating & Cooling for an assessment.
