Energy Efficiency in Dublin

Energy Efficiency

D1’s products are engineered to be the most energy efficient spas in the industry. In 1981, D1 Spas was the first company to manufacture a fully insulated spa. D1 hot tubs are insulated with urethane foam, which is used in commercial freezers, and come complete with insulated foam covers precision-fitted with linear heat-seal seams to prevent heat loss. Portable hot tubs account for less than 1 percent of the energy consumed in residential homes. In addition, D1 hot tubs and swim spas use up to 85% less energy than traditional in-ground pools.

Envirotect™ Skirting

D1 first offered Envirotect in 2001. These skirts are made mostly from post-consumer recycled milk cartons called HDPE (for high-density polyethylene.) It’s environmentally stable, does not give off harmful fumes and is recommended by the Healthy Building Network, a national organization of green building professionals and environmental health activists. Envirotect is the most environmentally friendly skirting material available on the market.
Recycled Materials in Dublin

Recycled Materials

D1 uses a substantial variety of recycled materials in its products and processes. Thermoformed sheet scrap is either recycled into new equipment boxes or sent to a recycler.

Smart Heat: D1 uses the most durable and reliable spa heater on the market. The output on this titanium heater provides optimal heat recovery and consumes a very low amount of energy.

AquaFlo® Pumps: D1 uses powerful massage jet pumps, expertly engineered and plumbed for 100% efficiency. It’s the highest power pump with the lowest energy usage that also extends the life of the spa.

VOC Gas Elimination

In 2001, D1 switched to 100% low-VOC glue, and in 2003, all spa plumbing was converted from glued joints to barb and clamp, further reducing VOCs (Volatile organic compounds). D1 also drastically reduced VOC emissions by switching from fiberglass-reinforced polyester (FRP) products to urethanes, which emit no VOCs.

Sustained Forest Lumber Exclusively

All D1 framed wood construction uses lumber from Sierra Nevada-grown sustained forests, thus protecting our nation’s old-growth forests.

Forest Stewardship Council Supports

D1 uses FSC paper in most of its print-based materials. Paper products with a “mixed sources” label support the development of responsible forest management worldwide. Such paper is from FSC-certified and well-managed forests and/or post-consumer reclaimed material.

RoHS Directive Support

D1 sells widely in Europe so the electronics used in our products are RoHS compliant. RoHS is the European Union’s stringent regulation that restricts the use of hazardous substances in electronics. The directive bans the placement of electronics on the EU market that contain specified levels of lead, cadmium, mercury, chromium and other substances.
