What is White Glove service?

Standard common carrier delivery options cover the cost of getting an item to your shipping address but our White Glove delivery service does that and more!

The White Glove agent will call to schedule a Call Before Delivery within a four hour window, which gives you the flexibility to work around your busy schedule and to prepare the space where your item will be placed. Upon delivery, trained professionals will unload your large item from the truck, bring it into the room of choice, unpack the item and remove all packaging debris from the premises.

Please note that White Glove delivery will typically add 5 - 7 business days to your order's transit, and only includes 30 minutes of on-site time. If on-site time beyond 30 minutes is required, you may be responsible for additional fees. While the agents will bring the items into the location of your choice, this service does not include set-up of the items being delivered, such as installation of casters, shelves, or other accessories. Small items will not be unpackaged individually; they will be set in place and debris and packaging material will not be removed.

Customer questions about this product

My business is at a high elevation; does this change anything when I order gas cooking equipment?
Many gas equipment manufacturers need to make adjustments to the equipment so it operates correctly at elevations over 2,000 feet. Sometimes we can special order from the manufacturer and have your cooking equipment delivered ready-to-go, but in cases where your unit is in stock and waiting to ship, you’ll need to have a qualified service technician come to your location and alter your unit at the time of installation so that it is compatible with a higher elevation. Contact our Special Orders team prior to placing your order, and we will let you know what will work best for the equipment you are planning to purchase.
Can this booster water heater replace a primary water heater?
No, it is not designed for that purpose. This unit should only be used as a secondary water heater.
Does this gas booster have more than one venting option?
Yes, for flexibility during installation, this item is available in either side or rear venting. Please select an option above prior to checking out.

Hubbell PT125 NAT Details

This Hubbell PT125 natural gas tankless booster heater is the smart solution to ensuring that your kitchen tools, cookware, and dinnerware are safe and sanitary after washing! Boasting an innovative tankless design, the unit requires less maintenance than units with tanks, while increasing efficiency to an impressive 90%. This gas booster heater is engineered for use with either conveyor or flight-type dish machines, and ensures that water heats to the proper 180 degrees Fahrenheit for food-safe sanitizing. Plus, its stainless steel exterior jacket and base keep the unit protected and free from corrosion, promoting long-lasting performance, even in heavy use applications.

Capable of heating 188 GPH from 110 to 180 degrees Fahrenheit, or 330 GPH from 140 to 180 degrees Fahrenheit, this booster heater operates with patented VariFlame technology, a temperature control system that eliminates the need for a standing pilot and boosts overall performance efficiency. When the unit is in use, you can monitor function by viewing the easy-to-read digital display. In the case of difficulties, the built-in self-diagnostic system enables self-service of the machine to cut down on costly, professional troubleshooting.

The unit includes a range of features designed with safety in mind. For instance, the ECO high temperature shut off immediately powers down the unit if it reaches unsafe temperatures for operation. In this case, you can use the manual reset to easily restore the machine and continue operation once in safer conditions. Another great safety feature of this booster heater is the brass pressure reducing valve, which is supplied with each booster heater. A finned tube copper heat exchanger, a temperature and pressure relief valve, and two temperature and pressure gauges are included, as well.

For optimal operation, the unit is equipped with a water treatment system for blended phosphate. This helps stop scale from forming and affecting the performance of the booster heater. The unit stands on 6" plastic legs, providing enough clearance for installation on the floor of your kitchen or dish washing area. It requires a 115V electric connection and a natural gas connection for operation.
