"They first came out to do a routine check and informed us of what we should / needed to do to have our fire place perform better. The quote they provided was very reasonable. We decided to install a rain cap after the sweep and getting an appointment was very easy. The technician arrived early and completed the work quickly."

Install Boiler questions, answered by experts

In some cases, conversion kits are available, but not all boilers are compatible. Conversion may require significant modifications and should only be performed by a qualified professional. Before making a decision, compare conversion costs to the cost of a complete replacement to determine the most cost-effective and reliable option for your home.

Costs range from $3,000 to $7,500, depending on system size and efficiency.

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.

Yes. In many cases, switching from an old furnace to a high-efficiency boiler can help you save money over time. You can also save money by switching from an electric boiler to a gas boiler, which costs much less compared to the energy bills an electric boil can create. Boilers are often (but not always) more efficient than furnaces, too. Then there are discounts, rebates, and incentives that can help you save on the initial costs.

The radiators closest in proximity to the boiler heating system will heat up first. Radiators in rooms farther away from the boiler will take longer to heat up and may be the coolest rooms in the house. The radiator unit itself should heat up evenly; otherwise, there may be trapped air inside it.
