"This was one of the worst remodeling experiences I?ve ever had. I was completely oversold on what they could deliver. I hired them for a bathroom remodel and was promised a spa-like retreat. What I got instead looked like a cheap hotel bathroom. The price was outrageous. They pitched me at around $38,000, and I agreed because I thought I was getting a high-end, premium product. That was absolutely not the case. The materials and design options were extremely limited. They only work with one brand, and they push it aggressively like a bad timeshare presentation. To make matters worse, the price didn?t even include the vanity or any accessories. I had to provide all of that myself. For nearly forty grand, that is completely unacceptable. The workmanship was okay, not great. They were in and out in a day, which was convenient, but it clearly came at the cost of quality. There are spots where the work looks rushed and careless. This is a $15,000 bathroom at most."

Install Boiler questions, answered by experts

The absence of heating or hot water, unusual noises like banging or gurgling, and visible water leakage are key signs. Abnormal boiler pressure, flame irregularities (for gas boilers), or pilot light issues may also signal trouble. Frequent cycling, soot or staining, and unusual odors, particularly gas-like smells, should not be ignored. Modern boilers often display error codes or lockout mode upon detecting issues. Uneven heating across radiators and rising energy bills without increased usage can further point to problems. Prompt attention to these signs is essential to prevent further damage and ensure safety.

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.

Modern boilers average around 20 years of use before failing, with some hitting 25 to 30 years. Older boilers, however, can last up to 50 years because they are often made from ultra-durable cast iron. Newer models are made from steel alloy and related components, which are great for withstanding high pressure levels and hot temperatures but offer a slightly lower life span.

Coolant and antifreeze are technically not the same thing. The difference between the two is the ratio of water to other chemicals. True antifreeze is mainly made up of either ethylene glycol or propylene glycol, while coolant comprises one part antifreeze and one part water. However, the terms coolant and antifreeze are often used interchangeably, even by pros.

It takes about five to 10 minutes for heat to reach a radiator, then about one hour until the radiator fully heats up a room. The exact duration depends on the size of the room and how far away the radiator is from the boiler heating system. Heating up an entire house could take up to two hours.
