"We needed our boiler replaced and had multiple companies come and look at the job. We ended up selecting Sila as we read good reviews on the company. Sila surpassed our expectations. The tech who performed the install (Gage) was on time, communicated the entire process to us from start to finish and did a tremendous job. He also made sure to clean up afterwards and was very professional. We would absolutely hire Sila again!"

"JT called and asked if he could come earlier than expected, which was perfect for me. He was extremely thorough reviewing our electrical system and the finished product of the work he did (installing a new 220v line for an outdoor hot tub) was clean and efficient. He was a joy to meet and speak to, incredibly nice guy. Price was reasonable for the work. I would 100% recommend JT and Cotti-Johnson again!"

"Plumber arrived within the specified time period set by the company. He was a professional with 17 years experience and was quite knowledgeable. He installed the toilet that I provided in an efficient manner, tested for leaks and cleaned up the area. Carried the old toilet to the curb. He also put a new handle that I provided on the shower valve that stopped the leak, thus avoiding a further cost to us!"

"Ed and his crew were wonderful. They installed a new boiler for us. The work is outstanding. The new system looks beautiful. They were very professional and respectful. They provided a proposal explaining everything in detail in advance. The price was very reasonable. I strongly recommend them and would definitely hire them again for my future heating projects."

"Boiler installation. Michael and his team did an excellent job replacing my leaking boiler with a new, efficient one. His quick communication, thoughtful explanations, professional workmanship, and competitive pricing (better than three other offers) made him the clear choice. I highly recommend working with them."

Install Boiler questions, answered by experts

If you want to have hot water in your home and part of your plumbing system, you'll need a hot water heater. An alternative may be to heat water as you use it, such as by boiling what you need on the stove. But that's much less efficient and takes considerably longer than hooking up a water heater. Another option is to rely on appliances, such as a dishwasher or washing machine, that heat the water themselves.

All modern boilers are condensing boilers because they’re the most efficient type. Instead of extra heat leaving through the flue, these boilers trap the heat and use it to heat the house. Whether you choose a combi boiler, system boiler, or regular boiler, you can opt to get a condensing system. If you have an old boiler that’s not a condensing boiler, it’s a good idea to get an upgrade.

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.

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.

Hydronic and standard electric baseboard heaters differ in how they operate, their cost, and their performance. Standard convection heaters use electric coils to heat the air directly, while hydronic heaters warm a contained liquid like water or oil, which then radiates heat into the room.

In terms of cost and efficiency, hydronic heaters usually have a higher upfront price but are more energy-efficient and cheaper to run over time. This is because the heated liquid retains warmth, allowing the heater to continue providing heat for a while after the thermostat turns it off. In contrast, electric heaters provide heat more quickly but are less efficient.

Ultimately, the better choice depends on your priorities. If you need a room to heat up fast and have a lower initial budget, an electric heater might be suitable. If long-term energy savings are more important and you don't mind a slower heat-up time, a hydronic heater is likely the better option.
