Are you looking for one of the most affordable ways to add renewable 
technology to a home or a commercial building? If yes, then incorporating 
solar hot water heaters is significant.
Typically, a residential solar water heating system minimizes the requirement 
for conventional water heating by around two-thirds. As a result, the system 
reduces the cost of electricity or fossil fuel for heating water and the 
associated environmental impacts.
Solar hot water heater
s
 provide you and your 
family with eco-friendly, 
clean energy for heating 
residential hot water, 
swimming pools, homes, 
and industries. Solar 
energy heats the fluid – 
water or glycol and 
transfers the solar heat 
directly or indirectly to 
heat water.
The initial cost of these systems can be slightly higher than the conventional 
gas or electric water heaters, but solar energy is free. In addition, with so 
many grants and low-interest loans available, a solar water heating system 
can cost less than a conventional heater upfront.
Solar hot water heaters can be of two 
types, i.e., active and passive. But the 
most commonly available are the 
active systems. They use heat 
pumps, while the passive solar water 
heating systems work on gravity or 
thermo siphon. Northern Lights Solar 
Solutions provides active closed-loop 
solar water heaters with pumps and 
digital controllers designed 
specifically for the solar industry.
However, solar water heating systems can do much more than just heat your 
hot water at home. Solar hot water heaters currently feature solar vacuum 
tubes that can be used for many applications like heating homes, space, 
commercial purposes, etc.
Solar-powered systems 
have become the 
rapidly growing 
alternative energy 
source throughout the 
United States and 
Canada because of 
government grants and 
low-interest loans. You 
should contact the 
Northern Lights Solar 
Solutions team and 
discuss taking 
advantage of solar 
heating systems and 
saving more dollars.

Usually, the heat transfer fluid used 
in these systems is a mixture of 
glycol and water, and glycol 
concentration depends on the 
expected minimum temperature. The 
glycol used is food-grade Propylene 
which is non-toxic. Typically, solar 
water heating systems are helpful for 
hot water heating and radiator or in-
floor home or commercial heating 
applications. The system is close to 
the atmosphere but can build up
