"Outstanding from first meeting & purchase to 24Kw Generac's first start up. Amanda Tallman is completely thorough explaining all installation steps & the numerous items pertaining to this model. On the final day, in the rain, alone Amanda improved the propane line installed by gas supplier. We were so grateful for installation before cold weather & frozen ground occurs. Completely SATISFIED with 4 POWER NOW Roger Sevilla Throop Township."

"The whole experience from start to finish was very professional and friendly. The team was in constant contact with us to make sure all of our questions were answered. The installer reviewed the process with us before he started and then gave a run through on how to use the new furnace and again asked if we had any questions. We will definitely recommend Sears to our friends."

Install Boiler FAQs, answered by experts

If you go to turn it counterclockwise and it won’t turn anymore, it’s open. Like most other valves, you should be able to turn a radiator valve counterclockwise (to the left) to open it and clockwise (right) to close it. To close a radiator valve, turn it clockwise until you meet some resistance and can’t turn anymore, but do so carefully to avoid breaking the valve.

No, there isn’t always water in radiators. In a one-pipe system, water is constantly circulating from the boiler to the radiators and back. In a two-pipe system, water travels through two separate channels: one that goes to your radiators and one that returns back to the boiler so it can heat up again.

Costs depend on unit size, labor, fuel type, and whether additional piping or venting is needed.

You can use a boiler and a furnace, although it’s not common to use both for whole-house heating. For example, your furnace may take care of HVAC heating through your vents, while a boiler powers your floor-based radiant heating in the bathrooms. Mixing and matching like this gives homeowners a variety of heating possibilities.

Since your boiler keeps you warm and provides hot water to your home, you’re likely to notice issues with heating in your living space right away. The most obvious sign that your boiler is breaking is not getting any heat or hot water. You might also hear some odd sounds coming from your boiler during operation, the flame in your gas boiler is not blue, the pressure is inconsistent, or your boiler is using more energy than it should. If you notice any of these signs, be sure to call a pro right away.
