Old boiler with rising gas bills
We compare repairs on the existing boiler with a new high-efficiency model sized to your radiators.
Boiler Installation & ReplacementBig older houses on West Main Hill take a lot of heat to keep comfortable, and an aging boiler running every room on one thermostat burns more gas than it needs to.

West Main Hill rises west of downtown Kalamazoo along West Main, and it is known for older, large homes. More rooms, taller ceilings and several floors mean a bigger heating load than a typical city house. Many of these homes heat with hot water or steam from a basement boiler, and some have added forced air or ductless units over the years for cooling.
Our technicians help West Main Hill owners decide when to repair an older boiler and when to replace it with a modern high-efficiency model. We also divide large houses into heating zones so the third floor guest room is not heated like the kitchen. Before anything is ordered, you see the options, the expected gains and a written price for each one.
A large house with hot-water radiators or baseboard can often keep its original piping and radiators when the boiler is replaced. A modern condensing boiler pairs well with that cast iron, because big radiators heat the rooms with cooler water, and cooler return water lets the boiler run at higher efficiency. Our boiler installation work includes sizing the new boiler by measuring the radiators in each room rather than copying the old nameplate.
Zoning is the second piece. Splitting the piping into zones, each with its own thermostat and a zone valve or pump, lets you heat the main floor during the day and the bedrooms at night. Rooms used only now and then can sit cooler. In houses that also have ductwork for cooling, our HVAC zoning systems can divide the air side too, so the top floor gets the cooling it needs in summer.

Kalamazoo heating seasons run from October into April, and large homes with tall ceilings and many windows feel every cold snap. Lake-effect snow and nights below zero push an older boiler to run nearly nonstop. Modern boilers use outdoor reset controls that read the outside temperature and adjust water temperature to match, running gentler on mild days and hotter on the coldest ones. That steady approach saves fuel and keeps the big rooms from swinging between hot and cool.
West Main Hill is a short drive from our downtown Kalamazoo office, heading west along West Main. A person answers (269) 360-5258 every hour of the day, including holidays. For boiler replacement or zoning, a technician visits to survey the radiators and piping, and that estimate visit has no charge. For a boiler that has stopped, the nearest technician on shift heads straight out.

Radiant Floor HeatingFAQ
In large houses with long heating seasons, the savings from a modern condensing boiler add up because the system runs so many hours. It works especially well with big cast iron radiators. We look at your current boiler, gas use and radiators, then show you what a new one would likely cost and save.
In most cases, yes. Cast iron radiators and the piping that feeds them can last a very long time. We check them for leaks and flush the system when the new boiler goes in. Keeping the radiators saves money and preserves the look of the rooms.
Adding zones to a hot-water boiler system in 49006 usually runs between $1,180 and $2,760 per zone, depending on the piping layout and whether zone valves or separate pumps are used. Larger homes often split into three or four zones. We quote after tracing the piping.
