More questionsWhich water heater or boiler size do I need?
Match the unit to your peak hot-water demand (gallons per minute at your required temperature rise) and, for boilers, to the calculated heat loss of the building. Each product page lists input, flow rate and turndown. Contact us with your fixture count and climate zone if you would like help comparing models.
Is installation included?
No. Gas water heaters and boilers must be installed by a licensed contractor, following the manufacturer’s manual and local gas, plumbing and venting codes.
Who can buy refrigerant?
Federal rules restrict the sale of some refrigerants, such as R-22, to technicians certified under EPA Section 608 or 609. Buy only if you hold the required certification or are purchasing for a certified professional, and never mix refrigerants or charge a refrigerant into equipment not rated for it.
How do refrigerant packs work?
Choose 5, 10 or 20 cylinders on any refrigerant product page. The 5%, 10% or 20% pack discount is built into the price you see before checkout.
Can I return an item?
You can request an eligible return within 30 days of delivery. Read the return conditions before ordering or installing a product.
