This test method is intended to apply to Indirect-Fired Water Heaters designed for installation with a hot water boiler or some other external source of heated water. This standard is limited to Indirect-Fired Water Heaters having a total...

This Standard describes the test procedures required to perform a 24 h simulated-use test. This Standard also provides the calculations required to determine the first-hour rating, maximum flow rate, recovery efficiency, standby loss, daily water heating energy consumption, uniform energy...

This Standard provides specific requirements and test methods for gas water heaters and central heating boilers, with an energy input not exceeding 500 MJ/h, and includes types intended for the supply of hot water at a maximum temperature of 99 °C for - (a) sanitary, potable...

This Standard specifies the method for determining the energy factor for oil-fired storage tank water heaters. This Standard establishes minimum energy efficiency levels for oil-fired storage tank water heaters. This Standard applies to oil-fired...

ul-732.6 Oil-Fired Storage Tank Water Heaters UL 732 1 Scope 1.1 These requirements cover oil-fired storage-tank water-heating appliances having a fuel input of not more than 200,000 Btu per hour (60 kW). These requirements do not apply to heaters that...

Approximately half of water heaters sold in the U.S. and Canada for residential applications are natural gas fired storage water heaters, and for these products the maximum steady state thermal efficiency of available products is approximately 96%, with transient...

This European Standard defines the specifications and test methods concerning the construction, safety, rational use of energy and fitness for purpose, and also the classification and marking of gas-fired instantaneous water heaters for sanitary uses, hereafter called...

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...
