Benefits of Servicing Your Boiler

The benefits of having your boiler serviced often outweigh the average cost. A properly working boiler is a money-saver itself. So, by ensuring that your boiler is working properly, you can potentially decrease your monthly electric bill and avoid having to pay higher amounts for more intricate service in the future. This will prevent serious damage to your boiler.

Besides saving you money, getting your boiler serviced regularly can also save your life. A faulty boiler can be extremely dangerous. It can leak carbon monoxide and lead to carbon monoxide poisoning -- which can be fatal. Servicing your boiler is the only way to ensure that it has no leaks and that your family is safe.

For optimal efficiency, use of a steam boiler is always preferred. New boilers use fuel to boil water, which then heats the home. This type of boiler depends on base boards to circulate hot air through different rooms. These boilers also contain condensers to get rid of excess moisture -- they waste very little, and although they can cost a few thousand dollars, they are sure to save many times that amount in the long run. When a newer boiler fails, the condenser is often the problem. If the condenser is not operating correctly, this affects how the entire unit functions, and you are probably wasting thousands a year in heating and cooling costs.

Costs Associated with Servicing Your Boiler

The cost of servicing your boiler can range from $50 to over $3,000. Many factors affect the cost of repairing a boiler, including which part or parts are broken, where the boiler is located, whether or not the boiler needs to be moved for servicing, whether or not electrical work is required, the type of fuel your boiler uses as well as the technician you choose to have perform the service.

The type of boiler you have in your home will also affect the costs associated with repairs and servicing. An oil boiler, unlike a gas or solid-fuel boiler, typically has higher installation costs, service costs and even costs more to run. Unfortunately, if you live in a rural area that isn't near any gas mains, an oil boiler may be your only option.

Replacing a boiler typically costs an average of $50-$300, but this price can be drastically higher depending on where you live and the location of the boiler. Replacing leaking, aging, or bad ductwork costs an average of $35-$55 a linear foot for labor and materials, depending on the length and type of ducts.
