Fired Hot Water Heater Standards

These requirements apply to door air heaters directfired with natural gas, propane-air mixtures. The word gas is used to designate these as gaseous fuels and propane is used only where specific reference is made to fuel/air ratio . These requirements apply to direct gas-fired door air...

This standard is for water heaters that control the outlet temperature to specific limits and are installed within a hot water distribution system but not at point-of-use. Description The water heater shall consist of a heat exchanger, a cold water...

This Practice provides minimum technical requirements for the process and mechanical design, materials, fabrication, inspection, and testing of electric immersion process heaters and associated controls, including thyristor control panels. This Practice applies to electric immersion process...

In the effort to achieve low-energy operation of residential buildings, advanced water heating technologies are vitally important. This paper explores the year-long performance of a 189 L (50 gal) heat pump water heater (HPWH) serving as an auxiliary unit to an active, indirect...

NOTE: This guide specification covers the requirements for heater scarifier procedures for bituminous pavements in connection with surface treatments or asphalt overlays.

This Standard applies to kerosine-fuelled appliances with capacities up to 4400 W that are primarily used as portable space heating appliances. Appliances with input capacities greater than 4400 W may beexamined and tested in accordance with these requirements and with any additional requirements...

This recommended practice (RP) covers the inspection practices for fired boilers, process heaters, and furnaces used in petroleum refineries and petrochemical plants. The practices described in this document are focused to improve equipment reliability and plant safety. The intent is...

This Guide specifies verification methods for compliance with the Government of Canada's Energy Efficiency Regulations (referred to in this Guide as the EE Regulations) as well as methods for establishing energy efficiency ratings for water heaters. This Guide is aimed at...

This European Standard is composed of two parts. The first part supplements EN 303 1, EN 303 2, EN 303 4 and EN 304 hereafter called boiler standards. It specifies the supplementary requirements and tests for the construction, safety, rational use of energy, fitness for purpose, classification and...

This Standard specifies procedures for 24 h simulated-use testing of gas-fired instantaneous water heaters. This Standard also provides calculations for the determination of (a) the maximum L/min (gpm) rating; (b) recovery efficiency (thermal efficiency); (c) daily...

Scope. This specification covers a hot beverage bag, to be used in conjunction with a flameless ration heater (FRH), a beverage powder and potable water. This item is for use by the Department of Defense as a supplement to operational rations.

This code deals with the design and installation of domestic water-heating systems, whether relying solely on electric heaters or using electric heating in conjunction with solid-fuel-fired boilers.

This document specifies fire testing requirements for water mist systems used for fire protection of industrial oil cookers. This does not include requirements for systems used for protection of other equipment such as exhaust air ducts, heaters, heat exchangers, and...
