Why Has My Boiler Suddenly Stopped Working?


A broken boiler is enough to completely redirect the course of your entire day. There are lots of things that could potentially go wrong. It may be that your central heating isn’t working, or your boiler isn’t heating the radiators even though you still have hot water. 

In more severe cases, your boiler might be fully unusable and unable to provide any heat or hot water at all. Regardless of the problem, you need boiler repair to get your home back to operating comfortably. 

There are things you can try before you call in professionals like the team at Paul The Plumber. When your boiler stops working, in certain cases, it’s possible to find the source of the problem and alleviate the issue on your own.

Boiler Problems and Solutions

A boiler is a complicated piece of equipment. Luckily, if you’re wondering what to do when your boiler stops working, you’ll find that a majority of cases revolve around the same set of issues. If any of the problems listed below match what you’re experiencing, that means there’s a clear-cut solution to pursue.

Leaking Boilers

Frequently, boiler leaks originate from internal problems, like faulty pressure valves or pump seals. This kind of leakage can come from high pressure within the unit or just natural wear and tear. 

Leaks can also come from corrosion or if technicians improperly installed the system. If you’re uncertain of the source of the leak, it’s best to call our team of professionals to help diagnose the root of the problem.

Boiler Has No Power

When your boiler refuses to turn on entirely, it’s important to check the other appliances in your home to determine the scope of the outage. If multiple fixtures are dead, then you can check your fuse box for any tripped switches. But if only your boiler is without power, it’s best to call an engineer to inspect the unit.

No Heating or Hot Water

Your boiler is supposed to heat your home and the water it uses. If it stops doing that, it can be due to a variety of factors. Maybe it’s low pressure, perhaps it’s a broken thermostat, or it could be a fault in the airlocks of motorized valves. 

Check your pressure gauge to see if it’s reading below one. If that’s the case, then you may require repressuring to get the heat back into your home. You can also check your thermostat.

How to Check if the Boiler Thermostat Is Working

In most modern homes, the heating system and the thermostat are connected and set on a schedule. So when one doesn’t turn on with the other, the problem may be a fairly easy fix. Sometimes it may be as simple as making sure the thermostat is switched on and charged with working batteries.

You can check that the temperature is turned up the way you like and confirm the WiFi connection if your thermostat requires one. Then make sure that you don’t have any standby options or new daily schedules that have been set. If all of that checks out and things still aren’t working, then you’ll want to take things a step further. 

Even if the batteries in your thermostat are fairly new, you can change them again to see if that helps. Clearing your settings and restoring the system to its factory settings can also help reset the system. If you still have your thermostat manual, it might be beneficial to scan the pages for insight. 

If all else fails and you find your boiler not turning on with thermostat intervention, it’s time to call the professionals. When you call on the plumbers at Paul The Plumber, you’ll be stunned at the level of care and skill we can bring to your household.

Had a well pump that was shorting out and pretty much had no water. Adrian from this company not only got out next day but was great to work with. He was very friendly and knowledgeable I would definitely recommend this company to anyone that needs work done! Thanks again guys!

D. Marchand

I cannot say enough about this company!!! Their only concern is that you are up and running again with no worries. I’ve had Kyle the plumber, and Josh their electrician out here and both are polite, well trained and you can tell they truly care about getting you back in service. Great service, well trained caring staff! I will never go anywhere else!

H. MacPherson

I would recommend Paul the Plumber 100%. They offered same/next day service. They were friendly, professional and quick – from the office staff to the technicians. Overall an amazing experience from start to finish.

Michele

I’ve used Paul the Plumber twice now for electrical issues and they have been wonderful each time. They are fast, polite, knowledgeable, and very fairly priced. They explain everything well and answer my questions thoroughly and I feel safer now knowing what was causing my electrical issues and having it fixed! I will be using Paul the Plumber for all my household needs going forward

J. Shea

John was wonderful. He found the problem right away and fixed it. He checked other outlets just to make sure I would be safe. He explained different programs the company offers also. I’m very happy.

D. Weaver

What a fantastic business. Helped us work with our water district in resolving meter replacement issues. They also fixed a pipe leak that had developed over time. Caleb was wonderful and answered our questions as well as working with the water district engineer on the meter issues. So easy to work with.

T. Minasian

These are the after photos of the Rinnai tankless water heater installation and vent to the outside. It was important to me that the crew was able to use the existing vent hole to the outside to run both the intake vent pipe and the outside vent pipe. It made the job very clean and did not change the appearance of the outside wall. A shout out to Mike E, Caleb, Josh & Corey

W. Chepren

I made an appointment on line the morning of July 31 and two trucks showed up at 1:00 pm right on time that same afternoon. Both guys were friendly and very knowledgeable. They quickly found the source of the wet patch on my ceiling which wasn’t the plumbing but a problem with the shower curtain. This is the second time I have called Paul. Both times I got outstanding service and will always call on Paul the Plumber for any plumbing problems in the future. Very reasonable cost for the visit.

V. Vincze

We had an issue with our water…too hard, calcium deposits, and very little pressure in our master bathroom shower only. The techs (Mike E. & Tyler S.) arrived right on time. They were friendly and very personable. After installing our whole house filtration system and successfully finding the issue with our master bathroom, they left the work areas in pristine condition. They were meticulous in their work, and I highly recommend them for any plumbing needs!

M. Richdale

Thanks to Mike Vallee from Paul the Plumber for responding to this new customer’s call so quickly. He was courteous, thorough, explained the repair he was doing and left the work area spotless. I highly recommend Paul the Plumber (and Mike!) to anyone looking for a reliable plumbing company.

S. Baraket

Never used Paul The plumber company before but I’m glad I did. Very courteous, professional and pleasant from the answering service (Diane) to employees (Jeremy). They diagnosed the problem and fixed it in no time. Very happy and satisfied with their service. Definitely will use again. Thank you

K. MacCallum

First time customer, and am very pleased with the whole experience. The highlight was definitely with the technicians assigned to the job and their work – Tyree and Corey were clean, polite, well-informed, and very helpful with some of the questions I had along the way. Their work appears to be top-notch, and they made sure no mess was left behind. Will definitely be calling and requesting these two again on any future needs.

S. DesMarais

Josh was amazing. He was able to install my ring doorbells with no issues. He also did a great check of my homes smoke detectors and a few electrical plugs. He was thorough, Knowledgeable, and easy to work with. I would definitely use them again.

J. Wojo

DJ from PTP was incredibly helpful and knowledgeable. My shower was not draining and it became a bigger project than I thought it would and they came out quickly and were able to fix my problem. Then when my water heater had a slow leak they came back out quickly to attend to it and fix my problem. I really appreciate their hard work. Thank you so much!! Would definitely recommend them.

K. Bernardo

We’re first time home owners and needed help with some plumbing and adding a filter system. They were able to get a technician scheduled to our house within a day or so of me contacting them. Mike was super helpful and was able to complete all the jobs in a timely manner, and also cleaned up the areas he was working in. Overall a great experience and would definitely use them for future jobs.

D. Lefort

Arrived as scheduled to fix a leak from the shower valve. Tried to fix old 30 or 40 year old unit but had to replace with a new one. Quality work, parts and cleaned up when they were done. Would definitely use again.
