Bowman EC 80-5113-1T heat exchangers provide a new solution for heating spas and hot tubs in just a fraction of the time taken by traditional electric heaters. Designed for use with an external boiler heat source, they can heat hot tubs in around 1 hour, using pre-heated water, or just 3-4 hours using ambient temperature water. And with the cost of electricity being much higher than gas or biomass, energy costs are substantially reduced too!
The table below enables the selection of the most appropriate heat exchanger for your swimming pool or spa. The information shows the amount of heat that can be transferred from conventional and condensing boilers, together with the basic dimensions of each unit. Additional heat exchangers are available but the two options shown are suitable for all hot tubs and swim spas. For further information please download the product brochure, contact us or your nearest stockist.
Note – Ratings and weight are specifically relevant to the titanium versions of each heat exchanger. Download the brochure for more detailed information. The heat-up times are estimated and based upon heating from ambient water temperature (quicker heat-up times can be achieved with pre-heated water).
| Part Number | Spa Size (m³) | Heat-Up Time (hours) | Max Pool Flow (l/min) | Heat Transfer at 82°C (kW) | Heat Transfer at 60°C (kW) | Dim. A (mm) | Dim. B (mm) | Dim. C (mm) | Weight (kg) |
|---|---|---|---|---|---|---|---|---|---|
| 5113-1T | 3 | 3 | 200 | 25 | 16 | 370 | 60 | 86 | 3.0 |
| 5113-2T | 10 | 5 | 200 | 50 | 30 | 456 | 140 | 86 | 4.0 |
*Heat-up times are based on the volume of water being heated from 15 °C – 39 °C with boiler water at 82 °C. Times may vary depending on ambient temperature and insulation of the spa during heating.
Every hot tub installation is different in some way, so, the answer can depend a number of issues: The capacity of the hot tub? The outside air temperature? The heating system type? In many installations, where the hot tub is being heated via an electric heater, the answer is ‘a very long time’ – in…
