"Computer did the "gotta send info to Microsoft" but when tried to reboot it ran through automatic repair without success. I did all the alternative without any success. He came and picked up the hard drive on Tuesday and returned it on Saturday. Fortunately he was able to "restore" without any data loss. Very happy with outcome."

Boiler Repair questions, answered by experts

Always consult your manual for specific pressure numbers. Many expansion tanks come pre-pressurized at a specific PSI range, anywhere from 12 to 40 PSI, designed for a range of home boilers. You should not have to pressurize an expansion tank yourself, only the boiler system. If your system has a tank that needs to be manually pressurized, this is generally a job for professionals and their tools.

If you hear your radiator clanking even when it’s turned off, it’s typically because there’s trapped water or air in the system, causing a pressure buildup. When you hear significant clanking, popping, crackling, or banging in a radiator that’s turned off, you’ll want to bleed the pipes or call in an HVAC specialist to deal with the problem (and prevent it from happening in the future).

If you're often struggling with radiator issues like chilly spots, leaks, or annoying noises, those are common indications that your radiator may need to be replaced. Corrosion, uneven heating, and persistent hissing sounds are common issues as well. When repairs become a regular chore and your home’s energy bills start to rise, a new radiator will bring the comfort and savings you need.

The average lifespan of a boiler is typically between 15 and 20 years, though some may last for as little as 10 years while others can reach 30. A boiler's longevity is influenced by several factors, including the quality of the unit, proper installation, and consistent professional maintenance.

The material also plays a significant role. Older boilers made from durable cast iron can last for over 20 years, with some functioning for up to 50 years. However, it's important to consider their lower efficiency, which can lead to higher utility bills. Modern boilers, often made from steel alloys, are designed to withstand high pressure and temperatures and have an average lifespan of about 20 years.

To maximize your boiler's lifespan, ensure it is installed correctly, have it professionally maintained each year, and address any necessary repairs immediately.

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.
