The THERM-X-TROL is designed to eliminate this problem by providing control of maximum pressures at a level below the relief valve setting. It also provides an additional space in the system to accommodate the increased volume of water created by thermal expansion, returning it to the system when hot water delivery is demanded. Maximum pressure is kept well below the relief valve setting by the THERM-X-TROL, with its pre-charged air cushion that is separated from system water. The relief valve does not open, therefore spillage is eliminated.
Lift gate service includes removal of your package from the truck and provides curbside delivery. A lift gate is a hydraulic lift on the back of a freight truck that moves heavy items from the bed of the truck onto the street. You do not need a lift gate if your delivery location has a loading dock or forklift.
