P r e s i d e n t ’ s M e s s a g e
Despite the hectic month of September, we had a great turnout at the September
ASHRAE meeting. We were fortunate to have John Fischer from Semco present of
Total Energy Wheels. The presentation was very interesting and talked about the
incredible energy savings that John Hopkins has seen since applying total energy
recovery wheels in their lab systems. In addition, the presentation discussed the
importance of using a high quality wheel that does not transfer contaminants from the
exhaust to the supply airstream.
As some of you may have seen on the Philadelphia Chapter’s website, October will
have two events. The first is the SMCA Engineer’s Night on October 5th at the
Downtown Club. Registration is free for design engineers and is due on September 20th
so sign up quickly if you are interested. The second event is the ASPE Product Show
and Technical Symposium on October 26th at the Clarion. This event will offer the
opportunity to gain 4 CEUs between 12:00 and 4:00 with eight different HVAC and
plumbing topics to choose from. The Product Show goes to 7:00pm. In addition, ASPE
will be giving out $2000 in door prizes throughout the night.
On November 14th, we will be hosting our event at the Radisson Hotel in King of
Prussia. The presentation will be on Integrated Project Delivery and will be presented by
E. Mitchell Swann. See our website for addition information.
Please tell us if you are willing to volunteer to help out with a committee or would like to
join the board. We look forward to seeing you at future events.

ASHRAE Philadelphia Corporate Sponsorships Available
The Philadelphia Chapter invites your company to join as a Corporate Sponsor for the 2017-2018 year. Your
firm’s participation in this program would enable us to make a wonderful donation to ASHRAE Research Promotion
which includes over $ 1.5 million in local research funding.
Corporate Sponsors are listed on our web site, in our newsletter, and in our annual directory. They receive free copies
of our directory and recognition at all of our events. With the ease of one payment, you may get all this, as well as free
dinner tickets good for our monthly meetings, and make a valuable contribution to ASHRAE Research at the same
time.
Since not all companies have the same financial capabilities or quantity of employees, we offer a few different levels of
corporate sponsorship. Each level will receive the same types of benefits, with some differences in quantities and
discounting.
We hope you will decide to join us as a Corporate Sponsor. If you are interested, please email us at
[email protected]. The Board of Governors thanks you for your continued support of ASHRAE. We hope
that this year is successful for your firm.

Principals of Condensing Boiler System Design
By Dennis Jones, P.E., Member ASHRAE
ABSTRACT
Condensing boilers can provide significant energy savings due to operating efficiencies as high as 98% as compared to
a peak efficiency of 80% for a conventional boiler. However, specifying a condensing boiler does not guarantee
achieving anticipated savings; careful attention must be paid to the heating water system as a whole. The first principal
is that low boiler entering water temperatures (EWT) are required to realize the advertised efficiency and AFUE
performance of condensing boilers. ANSI Standard Z21.13 specifies condensing boiler performance testing with 80˚F
(27˚C) EWT and a 100˚F (55˚C) temperature rise (delta-T), a condition not generally achieved with standard design
practices. Advantages of high delta-T systems include reduced boiler and pump energy use and reduced pipe sizing and
distribution heat loss. A condensing boiler is not a compact fluorescent lamp (CFL); you can’t simply plug it into a typical
system and expect it to save energy. Selecting a condensing boiler is the easiest and least consequential part of
designing a condensing boiler system. This paper provides basic principles for designing a heating system utilizing
condensing boilers. The remaining design principals are mostly related to how to achieve a low EWT. The paper
presents design principles for heat delivery to the space, coil selection, boiler selection, low mass versus high mass
boilers, piping system design, pump and control valve selection, use of buffer tanks, and boiler controls. The paper
presents a detailed description of each design principal along with recommendations as to how to achieve it.
INTRODUCTION
Experience over several years of commissioning buildings with condensing boilers is that about 90% of the boilers never
operate in the condensing range. Traditional design practices include designing and controlling hydronic heating system
to not return water cooler than 140˚F (60˚C) in order to prevent condensation of corrosive flue gases within the boilers.
Conversely the focus for condensing boiler system design is to return 80˚F (27˚C) water to the boilers to promote
maximum boiler efficiency. Little information could be found on recommended design practices for condensing boiler
systems and in discussing design issues with commissioning agents, design engineers, and boiler factory
representatives; it was clear there was no consensus on how to design these systems. The ASHRAE Handbook was of
little help, but it did encourage design of high delta-T hydronic heating water systems. Internet searches failed to locate
any design guidelines focused on optimizing efficiency in condensing boiler systems. Condensing boilers can provide
significant energy savings due to operating efficiencies as high as 98% as compared to a peak efficiency of 80% for a
conventional boiler. However, installing condensing boiler alone does not guarantee achieving anticipated savings;
careful attention must be paid to the boiler heating water system as a whole. Condensing boilers require entering water
temperature (EWT) in the 100˚F (55˚C) range to actually condense water out of the exiting flue gas. The onset of
condensing is with an EWT of about 130˚F (54˚C), but maximum efficiency occurs at an EWT of 80˚F (27˚C) or lower.
This EWT requirement varies with altitude, with condensation starting at 125˚F (54˚C) EWT in Denver. The following
design principles were developed for condensing water systems.
DESIGN PRINCIPALS
Principal-1 - Return Water Temperatures to the Boilers must not Exceed 80˚F (27˚C) to Achieve the Advertised
Boiler Efficiency
ANSI Standard Z21.13 tests and rates condensing boiler performance with an 80˚F (27˚C) boiler entering water
temperature (EWT) and a 100˚F (55˚C) temperature rise (delta-T) to produce a boiler leaving water temperature (LWT)
of 180˚F (82˚C). Condensing boiler performance is dominated by the boiler EWT. Figure 1 below shows a typical
condensing boiler efficiency curve from a manufacture and a theoretical performance curve.
