Grundfos SIGMA Waterheater

Much of the alternative energy conversation focuses
on solar or wind power. However, that dialogue
ignores one of the largest potential sources of power:
waste heat.

Pouring out of building mechanical systems, this heat
has tremendous potential to be captured. Instead of
allowing it to dissipate, waste heat can be used to save
immense amounts of power for buildings without
resorting to burning new fossil fuels.

Capitalizing on this enormous opportunity to conserve
and reuse, the Grundfos SIGMA Waterheater is a
sustainable, innovative solution that provides hot
water to commercial buildings without burning fossil
fuel.

This beautifully simple water heater harnesses existing
processes to maximize efficiency. It reclaims the
building’s own waste heat to produce hot water, thus
conserving energy on the cooling side and on the hot
water heating side. As water returns, the SIGMA
Waterheater pulls the excess heat out of the system,
increasing the efficiency of the cooling system while
also heating potable water.

The design showcases not only a commitment to the
environment, but also a truly useful, usable product.
Innovative fabric panels lift free of the sides for easy
maintenance. Using fabric for casing also reduces the
product’s weight by 30 percent, saving energy and
monetary costs for shipping.

Completely modular, the SIGMA Waterheater was
designed to expand. New modules can be seamlessly
added as demand increases or buildings grow.

iPad controls add to the benefits of the SIGMA
Waterheater. Industrial design seamlessly meets
interface design with technology-based monitoring
and maintenance regulators modeled for ease of use.

As we work towards cleaner energy, it is vital to get
the most use out of our traditional energy sources.
The SIGMA Waterheater assists in bridging this gap
while demonstrating the vital role that innovation and
efficiency plays in the clean energy equation.
