Remember the good old days when you could repair a heating system with a screwdriver, a pair of water pumps and some chewing gum? Remember when if you had a bearing assembly that was leaking out the weep hole and a No. 2 pencil took care of it, for a while? Or how about just replacing the helix on a stack switch relay? Or changing the bellows in the fuel unit? You do? Well, you had better keep that vision in your mind because you are not going to see them anywhere else. Like the song said, “The times they are a changing!”
Gone are the days of loading up a motor with oil or simply adjusting the bolts to quiet it down. Come on, I did it and I know I am not the only one. Well, I for one am glad to see the “good old days” gone forever.
The tape measurer has given way to the laser measuring device. Does anyone still use rotary thermostats anymore? Indoor Air Quality (IAQ) has become an industry of its own. I hope you have got the idea. We need to move on with our testing procedures and our education. Outdoor reset has been used in commercial work forever, and it is now coming to the residential home near you. If you don’t know how it works, well…
First, you need to understand that the building envelope is losing heated air to the outside. The colder it gets outside the more heat loss the building will have. But wait a minute; the outdoor temperature is never the same all the time, right? So the outdoor reset control will monitor this temperature and adjust the boiler temperature to meet the demand of the heat loss. Simply stated, the colder it is outside the higher the boiler temperature needs to be and the temperature can be lower when it is not so cold, You could do this yourself, if you wanted to be in your customer’s basement ALL THE TIME! If you don’t, well you can always sell your customer an outdoor reset control system. There are many on the market so why not save your customer some money and at the same time make some for yourself, or your company. Want to see a video on how it works?

Another thing that’s changing is how we treat oil lines. We used to say that we needed two oil lines (supply and return) whenever the oil burner is above the oil tank, right. Well, we have found out that this is not necessarily true, nor is it the best way to feed the oil unit, in my opinion. You see, if the return line should develop a leak for any reason, the fuel unit will not be aware of it until the tank runs out of oil! If we only had a supply line buried in the ground, and as soon as the leak developed the unit would shut down due to lack of fuel. A Tiger loop type device allows us to do just that. The “Tiger loop” type devices have been around for many years but just now are coming into the spotlight for safety reasons.
Circulators – they do a lot more than circulate fluid these days, a lot more. Today’s circulators move fluid very efficiently and quietly. Most are “wet rotor” circulators, so no oiling is needed. Tomorrow’s circulators will have the ability to change RPM s per the demand load. How you ask? You really need to see these units at the trade shows, coming soon to a location near you.
As I said, the times they are a changing! If you want to stay ahead of your competitors, and you have a good start by reading this and other articles, you need to stay abreast of this changing market. Make use of the internet for your training if you cannot get to actual hands on training in a classroom setting. I am a firm believer in hands on training because you can actually break something and then learn how to repair it! And believe me I have broken a lot of components over the years.
O.K., the new heating season is about to start. I hope the summer fun you had was good. Now it’s time to keep your customers warm and happy. As always, I enjoy hearing your war stories. So until next time write me at firstname.lastname@example.org
