FAQ:

Q: Which heat exchanger should I choose for my swimming pool or spa?

A: Bowman EC80 heat exchangers can be used with virtually any types of external heat source, including gas, biomass, LPG boilers, ground and air source heat pumps, plus the latest hybrid systems. The table below enables the selection of the most appropriate heat exchanger for your swimming pool or spa.

Q: How does a hot tub heat exchanger work?

A: Hot water from the external boiler enters the heat exchanger and circulates inside the outer ‘shell’ of the unit and over the tube core, whilst spa water travels through the tubes collecting heat on the way. The tube core is manufactured from titanium, one of the most durable materials available and perfect for spas and hot tubs.

Q: What is a shell and tube heat exchanger?

A: The prototypical shell and tube heat exchanger has only one inner tube, and is typically used to teach engineering students the basic concept of a heat exchanger. However, in practice, a pack of smaller tubes is much more effective because it greatly increases the heat transfer surface area (and has a minor positive effect on turbulence to boot).

Q: Can you use a wood furnace to heat a hot tub?

A: Hot Tub Heat Exchanger and Swimming Pool Heat Exchangers Use an outdoor wood furnace in connection with a hot tub heat exchanger or a swimming pool heat exchanger to heat your pool or hot tub. You can use an outdoor wood burning furnace to heat your swimming pool or hot tub. The outdoor wood boiler has a second set of ports, standard.
