Install Boiler questions, answered by experts

It can take anywhere from four hours to three days to replace a boiler with a new one. How long your particular boiler installation takes will depend on whether you need a gas line installed and if you’re switching to a new boiler system. 

Replacing a combination boiler or standard boiler with the same system should only take four to six hours. Meanwhile, switching from a conventional boiler system to a combination boiler system could take a few days.

You can replace baseboard heaters with many other types of HVAC systems, including forced-air furnaces, hydronic heating, and heat pumps. Each one has its advantages and disadvantages, so the best choice for you will depend on your budget, preferences, and the design of your house. If you aren’t sure which option is right for you, ask an HVAC pro for guidance.

The most important sign of a boiler problem is something happening unexpectedly, which is why regular boiler maintenance is important. Unexpected problems can include strange smells, new leaks, and unexpected noises that your boiler wasn’t making before. Additionally, if a boiler keeps shutting off or can’t maintain a specific temperature range, it’s time to call in an expert.

Some high-quality steam boilers come with 10-year warranties, but a well-installed, properly maintained model can last at least 20 to 25 years. Learning how to clean a boiler, getting an annual professional service, and keeping up with maintenance and repairs on your heating system are all important for getting the most out of your model. 

Unless they are connected to the same system, boilers and water heaters will both need their own expansion tanks. The only case they wouldn’t have separate expansion tanks is if the boiler is pulling double duty and managing a heating system while also supplying hot water for a home. In which case, you may not need a hot water heater.
