Gas Hot Water Boiler Testing

Laboratory tests on domestic gas and oil boilers

The hot water efficiency results (EN13203) for gas storage combi boilers were higher than the unexpectedly low figures obtained in a previous test programme on oil-fired storage combis. However, results are somewhat lower than instantaneous units with or without the "keep-hot"
