Energy-efficient Engineering
for Indoor Pools

Superior swimming pool ventilation

Founded by mechanical engineers 40 years ago, M&E is in Recotherm’s DNA.

Today, with 40 years’ experience in building commercial units, we’ve created one of the most energy efficient systems on the market. But we haven’t stopped there – we are always exploring new innovations to reduce energy consumption even further.

The experts the experts talk to The experts the experts talk to

Our experience in the industry means our engineers excel at designing and delivering AHU solutions to meet any requirement. For unconventional or unique projects, where there is restricted access or space within plant rooms or when working with existing infrastructure, we will engineer the most efficient solution for your project.

Key Features of Our Units

Energy-efficient Technology

Innovative heat recovery technology captures energy from the extracted air and uses it to precondition the incoming air, reducing the amount of energy needed for heating.

FAQs for Mechanical Engineers

Yes, Recotherm units can be weatherproofed for outdoor installation at no extra cost. However, the control panel should be housed in a protected environment or placed indoors for easy access.

Yes, Recotherm’s swimming pool air handling units can monitor and adjust pool water temperature when fitted with the appropriate sensors and control valves, offering seamless integration with heating systems.

For most domestic installations, a single-phase supply is sufficient. Larger swimming pool air handling units for commercial applications usually require a three-phase supply due to increased capacity requirements.

Supply air should be directed over the coldest surfaces, typically windows, to prevent condensation. Swimming pool ventilation systems should avoid blowing air directly onto the pool water to minimise evaporation and energy loss.

Some smaller Recotherm units, such as those in the Aeris range, can operate on a standard 13-amp supply, making them suitable for domestic pools. Larger units may require a higher electrical capacity.

Yes, to maintain stable pool water and air temperatures, the boiler must be available at all times. However, Recotherm systems optimise energy efficiency by adjusting their operation based on real-time conditions.

It is highly recommended to distribute the air over cold surfaces, such as windows. However if this is not possible, the internal humidity can be adjusted as the external temp drops to ensure that the dew point of the air remains below the internal surface temperature of the glass.

Yes, the Aerum Recotherm unit is a boiler-free system that combines fresh air dehumidification with renewable heating technology. 

A pool cover will help to virtually eliminate evaporation from the surface of the pool water when the pool is not in use. Water costs money to heat and add to the pool, so anything that can be done to prevent water loss is advisable. There are certain pool shapes where it may be difficult to cover the surface of the water and neatly store the cover when it is off the pool. Careful consideration should be given to the pool design to try to ensure a pool cover can be incorporated. A pool without a cover will cost a lot more to run than one with a cover.

Yes, because when a cover is on the pool, the pool hall is generally unoccupied. Maintaining the normal 30°C air temperature would be wasteful, so the air temperature in the pool hall can be lowered during unoccupied periods. As well as lowering the temperature, the fans can also operate at a lower speed therefore reducing energy consumption.

Mechanical Engineers Testimonials

We are very pleased with the installation and the professional attitude and efficient service given by the Recotherm team. I wouldn’t hesitate to recommend them to anyone looking to maximise their air handling plant efficiency.
Graham Bugden, Chief Engineer – Interserve
“It was a shame to see such a beautiful historic building suffer from the damage caused by the lack of proper ventilation and heating. The new Recotherm unit was perfect for the job. It will make for a much more comfortable environment for swimmers and staff and prevent further damage to the building while reducing the carbon footprint due to being much more economical to run.”
Martin Cosnett – Hockley Mechanical & Electrical Services Ltd
“After many years of coping with the problems caused by their old AHU, our client is now benefiting from a reliable and energy efficient unit. The introduction of controlled fresh air has reduced condensation enabling them to resolve long standing issues with mould which were affecting not only the environment but also the infrastructure.”
Sam Doick – Dodd Group
