This could be dangerous, and time-consuming when you don\u2019t know what to look for. Technicians with the proper training can come to your home and make a quick assessment with all the tools they need to do so.<\/p>\n<p>Still, it\u2019s useful to know what <em>can <\/em>go wrong. That way, you know why it\u2019s so important to take care of issues quickly and have a better idea of what to expect.<!--more--><\/p>\n<h2>What You Can Fix on Your Own<\/h2>\n<p>There are a couple of things you should check before you call in a technician. If it doesn\u2019t appear that your boiler is powering on at all, it\u2019s always worth it to check the circuit breaker. Yes, even a gas system requires electric power. The pumps and motors won\u2019t operate without it! You can also check to make sure that the gas valve is open.<\/p>\n<p>It\u2019s also worth checking that the thermostat is powered on and set to the proper temperature. One final thing to look at is whether the boiler is leaking water. If this is the case, act quickly to shut off the water and call in a technician.<\/p>\n<h2>When a Boiler Produces No Heat<\/h2>\n<p>If it\u2019s not an issue with the thermostat or the circuit breaker box, there are many things that could be the source of a problem when a boiler will not heat.<\/p>\n<ul>\n<li><strong>No Pilot Light<\/strong> \u2013 If you don\u2019t know how to light this yourself, we recommend calling in a technician.<\/li>\n<li><strong>Problematic Electronic Ignition <\/strong>\u2013 Modern systems actually use electronic ignition, rather than a standing pilot. This means you will not be able to light it yourself, and the ignition system could require replacement.<\/li>\n<li><strong>Low Water Pressure <\/strong>\u2013 Pressure levels in the water tank should be maintained at about 12-15 psi. If it\u2019s lower than 12 psi, the boiler may not operate.<\/li>\n<\/ul>\n<h2>When a Boiler Performs Poorly<\/h2>\n<p>Then, there\u2019s the possibility that a boiler is not working properly. You may notice low heat or that heat is imbalanced from room to room. In this case, there are many possible components responsible, and this is by no means an exhaustive list.<\/p>\n<ul>\n<li><strong>Mineral Deposits in the Boiler <\/strong>\u2013 Hard water is what happens when there is an excess of minerals in the water supply. Deposits can collect in the tank, changing pressure levels, and it may need to be flushed.<\/li>\n<li><strong>Problems with the Expansion Tank <\/strong>\u2013 Water levels could become too high or too low in the expansion tank, which is meant to take in excess water to keep the water from boiling. (Despite the name, this is not actually supposed to happen.)<\/li>\n<li><strong>Faulty Circulating Pump <\/strong>\u2013 The circulators move hot water throughout the radiators in the home, so a broken pump will mean a major issue.<\/li>\n<\/ul>\n<p style=\"text-align: center;\"><strong><a href=\"\/contact\/send-message\" target=\"_blank\" rel=\"noopener noreferrer\">Contact Max Sr &amp; Paul Schoenwalder Plumbing, Heating and Air Conditioning, A Corp.<\/a> and learn more about what could go wrong.
