At Patriot, our mission is rooted in a commitment to serve the community.

"Although I am pleased with the completed shower, I did not have a great experience. Mason was the sales man, and he was lovely except during the sales process he showed me doors that they no longer stock. No big deal except the doors that we agreed on were not what was delivered. Jim the project manager came out and measured the enclosure , then ordered what we had agreed and put a deposit on. We were told it may take 10 weeks to come in?. It did.

Install Boiler questions, answered by experts

No, professional installation ensures proper venting, safety, and efficiency.

A heating expert will be able to clarify whether it's worth the cost of replacing your radiator based on the cost of repairs. Between parts and labor, you'll pay between $250 and $2,500 for a new radiator depending on the type of unit. If the long-term costs of fixing a radiator are higher than replacement, it's best to update your model.

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.

Common problems include leaks, low pressure, and inefficient heating. Regular maintenance prevents many issues.

A furnace is a big unit where gas, heating oil, or electricity heats the air. The warmed air is then pushed back out through ducts and vents. 

A boiler uses electricity, heating oil, or gas to heat water that is pushed into the room through a radiator. This is one of the oldest and most effective ways to heat a house, but radiators can also be unsightly and leave hot and cold spots in the room.

Heat pumps use a refrigerant to move heat from outside into the house and return it to the room through ducts and vents.
