Helpful Buying Guide

Choose water heater accessories for the job at hand

Start by identifying whether the work involves elevating a compatible heater, improving hot-water delivery at a distant fixture, resealing an access opening, or cleaning mineral deposits from water-operated equipment. Then match the accessory to the equipment configuration and the stated size, shape, thickness, pressure, temperature, or system requirements.

Use Cases

Support installation and maintenance work

Select a stand to raise a compatible water heater tank above the ground, a recirculation kit for applicable tankless-heater hot-water distribution, gaskets for access-opening service, or descaler for removing water-formed deposits.

How to Choose

Match the accessory to the specification

For gaskets, verify opening type, profile, dimensions, thickness, and stated operating limits. For recirculation, confirm tankless-heater and single-pipe-system compatibility. For stands, confirm the heater capacity and support-area requirements.

Applications

Cover common water-heating tasks

Representative applications include water-heater installation, tankless hot-water recirculation, manway and handhole sealing, and maintenance of water heaters, boilers, heat exchangers, ice machines, and other water-operated equipment.

Additional Information

Review stated operating and cleaning details

Spiral-wound gasket options have stated limits up to 1,999 psi and 1,000°F, depending on the item. Rubber manway gaskets have separate stated limits for steam and for water, condensate, and air. The concentrated descaler is NSF/ANSI 60 certified for use as a cleaner in potable water systems.

Planning Guide

Plan the right fit before choosing

Installation and hot-water delivery

Select stands and recirculation components by system fit

A galvanized water heater stand provides an 18-inch elevation and a 21 x 21 inch support footprint for compatible water heaters up to 50 gallons. For tankless heaters without a built-in recirculation pump, an on-demand recirculation kit works with single-pipe hot-water systems up to 600 feet of total pipe length.

  • Match stand capacity and footprint to the compatible water heater.
  • For recirculation projects, confirm the heater does not have a built-in pump.
  • The recirculation kit includes a circulator, flange kit, valve, hose, tee, push button, and receiver.
  • Its automatic temperature valve maintains 95°F at the valve.
Gasket replacement

Verify opening shape, size, thickness, and service limits

Manway and handhole gasket choices include elliptical and obround profiles in spiral-wound construction, plus elliptical rubber manway gaskets. Compare the existing opening and required thickness before choosing a replacement. Stated pressure and temperature limits vary by gasket type and item.

  • Elliptical manway gasket options include 11 x 15 inch and 12 x 16 inch configurations.
  • Handhole options include elliptical 3 x 4 x 1/2 inch and obround 3-1/4 x 4-1/2 x 1/2 inch configurations.
  • Listed spiral-wound thicknesses include 0.175 inch and 1/4 inch.
  • Rubber manway gaskets are intended for compatible steam, hot-water, cold-water, condensate, and air applications within their stated limits.
Cleaning and upkeep

Address mineral buildup in water-operated equipment

Concentrated descaling solution dissolves scale, lime, rust, and other water-formed deposits from internal water passages. It is a maintenance option for water heaters as well as boilers, ice machines, heat exchangers, and other water-operated equipment.

  • Use the descaler where mineral buildup affects equipment operation.
  • The solution is non-toxic and non-corrosive.
  • It is NSF/ANSI 60 certified for use as a cleaner in potable water systems.
  • Review equipment requirements before cleaning internal water passages.
