Knowing the warning signs of a broken boiler can save you from expensive repairs. Even when your heat still works, there are things our professional plumbers look out for:

No Hot Water Coming From Your Boiler: If your home has no hot water or heat from the radiators, you may need a new boiler. A low-pressure gauge on most boilers usually indicates something wrong with it and will often indicate which part needs to be replaced for it to function correctly.
The Boiler is On, But Not Heating Consistently: Is your home boiler unit not giving you enough heat during winter? The water is likely not circulating correctly, so if it’s been a while since the last time that this happened, there could be some clogged-up pipes needing cleaning.
Your Home’s Utility Bill Is Unusually High: If you notice that your energy bills are higher than last year or what the neighbors pay, there may be an issue. Boiler units that are in the process of breaking down will work less efficiently, causing a dramatic increase in monthly utility bills.
Home Boiler Systems are Prone to Cracking During Seasonal Changes in Temperature. Maintaining a steady flow of water is one of the most essential parts of your home’s plumbing system to prevent leaks and cracks. This will help ensure an efficient boiler, which means lower energy bills.
Foul Odors Surrounding Your Boiler: It might be a safety concern if you notice unpleasant smells coming from your boiler. If gas and the situation don’t improve after ventilation efforts have been made, there could be even more serious problems that require professional help to investigate.
