What is counter flow? Why is it more efficient?

With a counterflow arrangement, the cooling medium flows in the opposite direction to the liquid being cooled. Find out why this is so much more efficient.
How to heat a hot tub faster…

Significantly faster heat-up times and reduced energy costs. Why using an external heat source, linked to a Bowman heat exchanger, is revolutionising hot tub heating.
Terminal velocity..…Don’t let it kill your heat exchanger!

Ensuring the correct velocity of cooling medium through the heat exchanger is vital to the long-term health of the unit. Get it wrong and results could be terminal.
How do I heat my pool faster?

It’s a question asked so many times by pool owners. Yet the answer could be far simpler than you might expect!
Why doesn’t my pool heat up faster?

Why doesn’t my pool heat up faster? If your pool isn’t heating up to the required temperature, there are a few possible causes. Using this check list could help you locate the problem.
Reducing hot tub heating costs – significantly!

Rising energy costs are making many owners to reconsider using their hot tubs, but this solution heats them fast and can reduce energy costs by over 60%!
Why selecting the right heat exchanger is vital for your pool

‘’Why are Bowman heat exchangers so efficient?’’ and ‘’How can such a small heat exchanger possibly heat a pool this size?’’ These two questions are often asked and the answer is really simple.
