Hot Water Boiler Reset Control - Richard, We are looking at replacing our boiler with a new hot water boiler. The HVAC contractor, I suppose he is the salesman for the HVAC contractor, is trying to sell us what he refers to as a reset control for our boiler. He tells us it will save us more money by making our boiler more efficient. I think I understand how it works but my wife is not entirely sure about it. Can you tell us what you think about a boiler reset control and how it works?
Thanks, and we have learned so much from High Performance HVAC. And keep up the good work.
Oil Furnace Boiler Pump - A major component of oil furnaces is the oil pump and its job is to pump oil from the oil tank to the oil burner. It is important that the oil system is primed and free of any objects or particles that can plug the system. As well the oil pumping system must have integrity with no holes in the oil pipe where the pump can suck air into the oil line. Any air sucked into the line or a plugged oil line will cause problems with the oil burner that may result in a non-functional burner or a burner that does not produce efficient heat. (more…)
HVAC Fire Safety - I’m not sure how many HVAC technicians have heard of on-the-job horror stories. Whether the job was commercial or residential. However, I am certain they have happened as I have heard of these horror stories happening to others.
Whether you have ever heard of it happening to others or even if it has happened to you it is important that we remain forever vigilant. This is absolutely true when it comes to fire safety on the job. Especially when we are constantly using fire as a part of our job.
And especially for silver soldering (brazing), soft soldering, or even when we are working on gas or oil boilers or furnaces. Here is an account of a few things that I’ve personally experienced and the lessons learned from these occurrences.
Boiler Maintenance | HVAC Heating - Almost as if by rote many maintenance departments begin their annual maintenance in late summer to get ready for the cooler weather. Does your department understand how important the code is or do they take all this for granted?
Do they understand that if an accident were to occur all these maintenance procedures will be placed under a microscope especially if someone is injured or worse, killed? Along with OSHA (Occupational Safety and Health Administration) and local code enforcement not to mention private firms hired to investigate an accident and that someone or something will be held responsible for the accident.

Boiler Combustion Efficiency | HVAC Heating Systems - It is important to understand that a commercial application (can also apply to residential boiler applications) is going to consume a large amount of the energy budget, therefore it is important to track efficiency ratings because a slight drop in the efficiency can cause a sharp increase in the energy costs.
