Boilers Part 17 – Restrictive Heat Exchanger = High Pumping Costs

November 30, 2010

The second disadvantage of most Direct Vent Condensing Boilers is their restrictive heat exchangers. Not all DVCB have this disadvantage however so you must make sure to ask your contractor about this. Let’s say that you have a 3,000 square foot home with an 80,000 BTUH boiler. You would probably need about 8-10 GPM or 8-10 gallons of water passing through your boiler per minute. Most boilers would have a pressure drop through your boiler of 8 feet of head. The best boilers have a pressure drop as low as 5 feet of head. This means that with the right boiler your pump will work half as hard. Pumping water around your house uses quite a bit of electricity. With a non restrictive heat exchanger, you will be able to keep this cost to a minimum.

Make sure that your contractor understands pump and boiler flow curves so that your system will be designed to run as efficiently as possible.

Installation Quality – Controls and Wiring

September 1, 2010

Today’s appliances are very sophisticated and require advanced controls to operate them properly. Comfort systems heat and cool with multiple stages, they humidify and dehumidify, they communicate and troubleshoot and even notify you when to call for service and perform maintenance.

Wiring these systems requires a level of expertise that is much more advanced than what many companies have today. Without this training and expertise, your system will not operate properly and you will not maximize the functionality and efficiency of your investment.

Live Green – Save Energy

August 26, 2010

Did you know that if you just do nothing, your fuel bills will increase by 10% – 20% each year just due to rising utility rates. In this video, John Barba from Taco-HVAC outlines how you can save energy from your heating system. He distinctly points out how important it is that any contractor you consider for a system upgrade, do a thorough heat loss study to ensure that you are selecting the right equipment. John was interviewed by a television show called Designing Spaces. Click here to watch it now.

Variable Speed Pumping saves Money

June 28, 2010

One of the biggest uses of energy in a hydronic system is the circulator. This cost can be minimized by adjusting the rate of pumping according to the need of the building. It can be further minimized by using and ECM motor. Taco just came out with a wonderful circulator that can modulate itself, tell you how much power it is using at any time and is ECM. This pump is so advanced, so revolutionary, and so efficient, Taco actually made a contest for who can come up with the best name for this unit. I entered “The Chief”. CHIEF stands for Commutating HI Efficiency Flow. The prize is a flashy new Smart Car. I hope they select my suggestion and award me the car. Either way, I am a winner because I will be able to use this product to the advantage of my clients.
