Our
self supporting shells enable us to do things differently from many other spa manufacturers.
Despite recent pressure to reduce foam application, even some premium brands still use expanding
two-pack foam to support their shells.
This
foam not only degrades over time and impairs servicing, but can also release very high levels of
VOC’s into the environment during application. This is can be very destructive and polluting;
damaging water courses, soil, groundwater, the atmosphere, wildlife, and the respiratory organs of
the workers who apply it.

Advocates of
environmentally-friendly products, and safe working conditions, Monarch now use a
safe, environmentally friendly, yet equally effective alternative to foam which enables waste heat
to be re-used.
Pumps get very hot during operation, so much in fact
that they need a large breathing space. Because foam-filled hot tubs don't have an air space for
pumps to breathe, vents are cut into the access panel so that this heat can
escape.
However, our new perimeter-insulated
models, utilise this waste heat. The pumps heat the air space under the pool, as this rises above
the water temperature, the waste heat is drawn through the shell and into the spa
water.
Re-using this waste heat not only
reduces running costs, but also helps to maintain water temperature during cold weather
use.
Our perimeter heat
reflection system recycles waste heat from our pumps, making our spas some of the most
efficient you can buy.
Many hot tub covers, feature "steam-stops" at each end of the cover hinge (see right) to prevent
heat escaping from the join between each half of the cover.
However, this leaves a 3cm join along the centre of the spa cover without any insulation at all.
Heat rises, and this is highest point that heat can build escape, however Monarch Spas' new
steam flaps are full-length, making your hot tub cover much more effective than conventional
ones.
