Boiler Installation in Leawood, KS
Plenty of older Leawood and Johnson County homes were built around hydronic heat — hot water circulated through radiators or baseboard rather than forced air through ducts. It’s quiet, even, and comfortable, and when a boiler reaches the end of its life, the right replacement keeps that comfort going for decades. 7th Degree Heating and Air installs hot-water and steam boilers, sized correctly and matched to your home’s existing distribution.
Cast Iron or High-Efficiency Condensing?
Boiler installations generally come down to two paths. A traditional cast iron boiler is rugged and long-lived, a proven match for older radiator systems. A modern modulating-condensing (mod-con) boiler reaches much higher efficiency by extracting heat that a conventional boiler sends up the flue, modulating its output to the actual demand, and venting through PVC — but it requires the right system design and water conditions to deliver on that efficiency. Which one fits depends on your existing radiators or baseboard, your home, and how the numbers work for you. We size with a proper heat-loss calculation rather than simply matching the old unit’s rating, since an oversized boiler short-cycles and wastes fuel.
What Our Boiler Installation Includes
- Heat-loss sizing matched to your home and existing distribution, not just the old boiler’s nameplate.
- Correct near-boiler piping — circulators, expansion tank, and controls done right, which is where boiler longevity is won or lost.
- Venting to code for the boiler type, including PVC for condensing units.
- Gas line and pressure verification on your natural gas service.
- Permits through the Johnson County building department, with the old unit removed and disposed of.
Frequently Asked Questions
- What is a boiler and how is it different from a furnace?
- A boiler heats water and circulates it through radiators or baseboard (hydronic heat), while a furnace heats air and blows it through ducts. Boiler heat tends to feel more even and is quieter, with no forced-air drafts — which is why many older Leawood homes were built with it and why owners often want to keep it.
- Should I install a cast iron or a condensing boiler?
- A cast iron boiler is durable, simpler, and a natural match for older radiator systems. A modulating-condensing boiler is far more efficient and modulates to demand, but needs appropriate system design and lower return-water temperatures to hit its efficiency. We assess your existing system and lay out the tradeoffs and costs rather than defaulting to one.
- How long does a boiler installation take?
- Typically longer than a furnace swap, because near-boiler piping, circulators, controls, and venting all have to be done correctly. A straightforward replacement is often one to two days; switching boiler types or reworking piping can add time. We give you a realistic schedule with the quote.
- Is hydronic (boiler) heat better than forced air?
- It’s a matter of preference and what your home is built for. Hydronic heat is even, quiet, and doesn’t blow dust around, which many people prefer. Forced air is more common, integrates easily with cooling and filtration, and is usually cheaper to install. If your home already has radiators or baseboard, keeping and upgrading the boiler is often the sensible path.
- How do you size a replacement boiler?
- With a heat-loss calculation based on your home, not by copying the old boiler’s rating — which may have been oversized. An oversized boiler short-cycles, wastes fuel, and wears out faster. Correct sizing matched to your radiators or baseboard is what delivers comfortable, efficient heat.
