Boiler Maintenance, A Step By Step Guide
With our boiler maintenance tips you can do it yourself and save. A hvac service
call will normally cost around $100. With a little help, you can do it yourself and keep the $100.
And, while you are at it, we will show you some simple improvements you can make. These improvements will
not only save you money in operation but also help your system to last longer. (The normal boiler
maintenance call would not include tips to improve your current system's performance.)
If your unit uses gas or oil, you should start by examining the vent pipes. For an 80% efficient unit
this will be made of metal. You should check for rust and make sure the pipe is not blocked. Sometimes,
birds will make nests in these. Also, you should make sure that the connections are not coming apart. For
a 90% unit, they will be made of pvc. You should make sure the joints are not coming apart and that the
pipes are not blocked.
Next, you should check the inside for excessive dirt or rust. You can clean as necessary with a vacuum
cleaner but make sure you turn off the power first.
Now you should oil the circulator pump and motor if it has oiler ports. Most of the newer pumps do not
You should also check your thermostat(s). If they are not digital, they must be perfectly level. If they
are not they lose their accuracy.
**HOT TIP** Replacing your old thermostat(s), if they are the
old mechanical type, with digital units is a very inexpensive improvement. It is an easy diy project that
can pay big dividends!
Now, you can start the system by turning up the thermostat. Allow the system to heat up. Then, if your
radiators have manual air vents on them, you should bleed the air out of the system. With a small
screwdriver, you crack open the vent until water starts to come out. Then, you move on to the next one.
Check for other vents at the boiler and do the same thing. After you have finished, you can set the
thermostat to maintain the desired temperature.
**HOT TIP** If you have the old manual air vents, replacing them with automatic float
type vents will greatly improve system performance. It is an easy project that will make you more
comfortable and save money!
At this time, you should also check your carbon monoxide detector for proper operation. Check to make
sure it is not due for replacement. It should be tested at least monthly during the heating season.
