Engineered for efficiency.

Our energy efficient hot tubs are designed to keep heat in and costs down - thanks to advanced insulation systems that trap warmth where it belongs.

With HeatBank insulation boards, 33mm sandwich foam bases, and full-foam coverage beneath every seat, you’ll enjoy powerful performance with surprisingly low running costs.

And for the ultimate in efficiency, our Ultra Eco models feature extra-thick insulated lids and can be paired with a heat pump for even greater savings.

More comfort. Less energy. Every soak made smarter.

Note: HeatBank boards are optional upgrades on most models, standard on some. 33mm Sandwich Foam bases are in our Eco and Ultra Eco ranges. Full Foam insulation is on Ultra Eco ranges.

Designed for warmth that lasts

Every H2O hot tub is built with intelligent insulation in mind. Our combination of HeatBank insulation boards, CFC-free foam under-shell insulation, and 33mm sandwich bases on selected models creates a multi-layered thermal barrier.

That means less heat escapes, your heater works less, and you save more on running costs all year round.

Our full-foam systems fill every corner of the cabinet - wrapping pipework, pumps and fittings in insulating protection. The result? A quieter spa, greater energy retention, and faster heat-up times.

The science of efficiency

Heat naturally escapes through the base, cabinet, and cover - so we’ve engineered each area to resist thermal loss.

The 33mm insulated base prevents warmth seeping into the ground, while the dense full-foam insulation around the shell stops convective heat transfer.

Our HeatBank boards (optional on some models, standard on others) then reflect radiant heat back into the water where it belongs. Together, these systems reduce heat waste by up to 30% compared with older, uninsulated designs.

Ultra Eco — the next step in savings

Our Ultra Eco models add another layer of performance. They include thicker, high-density covers that seal in heat even on frosty winter nights.

Combine your spa with a compatible air-source heat pump and you can cut running costs dramatically - often saving hundreds of pounds a year compared with traditional heating alone.
