I actually thought that when we purchased our condo we would sell it long before we needed to upgrade the boiler, my associate and I purchased the Heating and A/C system about 30 years ago plus now we just had a upgradement unit put in, then even though the current one is far more efficient it is still taking me some time to get used to how it operates. Technology sure has changed over the past 30 years plus I cannot suppose how quiet my current system is. Not only that it takes up far less room than the old cumbersome one that was in the basement plus we are gleeful about that as well, however i was reading the manual the other afternoon plus I became confused because I was trying to find out how to relight the pilot if it goes out. I had to do this at least a couple of times a year during the winter time because there were drafts in the basement which would cause the pilot to blow out. No one in the manual did find a way to do this so I ended up calling the Heating and A/C company to ask him how I go about fixing the complication when it happened. The company kind of chuckled when I asked this question plus told me that pilot lights were a thing of the past plus the newer systems had an igniter system instead. Explain that this was an electronic spark that caused the boiler to heat plus it was one of the reasons why they were more fuel efficient. I no longer had a pilot light that burned 24/7 plus the igniter switch also would not be bothered with drafts that might be in the room. I thought this was pretty cool plus it was fantastic to know I wouldn’t have to worry about that.
