"When my water heater died I called a bunch of places, and nobody could make it out until the following week. A friend at work recommended Mull Bros. I spoke to Tom, and within 30 minutes an expert was at my house putting in a new tank. They are so friendly and nice, and you can see they love their work. I would definitely hire them again."

"The thermocouple on my gas-fired boiler needed to be replaced, and the pilot needed to be cleaned. The tech was helpful and forthcoming with information. Took about an hour, as my boiler does not have easy access. Would hire again!"

"Precise HVAC was wonderful. I actually was going to get more quotes but after working with their salesperson I decided to not even bother. They answered all my questions and made suggestions for things I didn't know about. I'm not even sure I care if I got a better quote or not. With Precise I know that they cross the t's and dotted the eyes and I don't have to worry about missing something."

"Juan responded quickly on a Sunday afternoon. He was very knowledgeable and fixed the broken part. Fortunately, Juan had the part in his truck and was able to get my furnace working again. The service was impeccable! However, the weekend rates are expensive the service cost me $699 for installation of a $70 part. The 2-hour service call was $500 ($249 per hour)."

Install Boiler questions, answered by experts

Boilers are equipped with multiple safety features to ensure safe operation. These include pressure relief valves to prevent overpressure, temperature high-limit switches to avoid overheating, and flame failure safety devices in gas boilers to cut off the gas supply if the flame goes out unexpectedly. Low water cutoffs prevent operation with insufficient water levels, and pressure gauges help monitor pressure levels. Ventilation and flue systems prevent the buildup of harmful gasses. Boilers often feature error code systems for automatic shutdown during malfunctions and gas leak detection for safety. Regular maintenance is crucial to ensure these safety features function correctly.

There are several types of home radiators, and the most common are steam heat radiators, electric radiators, and dual-fuel radiators. Steam heat radiators are connected to a boiler. Electric radiators can operate without being connected to anything else—they just need an electrical outlet. If you have a dual-fuel radiator, you’ll see a valve at the bottom of the system with a wire coming out of it and going into a wall. These are often your towel radiators in the bathroom. The type of radiator you have will impact how you turn it on.

Boiler installations and replacements cost between $3,600 to $8,400. Expect to pay around $5,900 on average for a new boiler, including installation. Adding new radiators or heaters to the boiler may include separate costs if you are also upgrading those components, so the final price may be higher. To decrease costs, you can look for local energy rebates for using a boiler and wait until installers are offering discounts for a first-time installation.

Yes, government incentives and programs are available to encourage energy-efficient upgrades in many regions. These incentives may include tax credits, rebates, grants, and low-interest loans for homeowners who invest in energy-efficient improvements such as HVAC system upgrades, insulation, and efficient windows. The availability and specific details of these incentives can vary by location, so check with your local government or utility company to explore your options.

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