Modelling and simulation of the solar thermal energy system using TRNSYS software was performed. The test results were analysed in terms of solar fraction, solar efficiency, and the effects of thermosyphoning and stratification in the solar storage tank. Sunny, partly cloudy and cloudy conditions were explored. Experiments were performed on the SDHW system during a different season of the year, over the period March through October 2011 to assess the system performance for different solar gain and water draw schedules. The experimental test setup includes two solar panels, a solar preheat tank, and an auxiliary propane-fired storage water heater, and an air handler unit for space heating. This paper presents thermal performance results of an experimental and numerical simulation study of a solar domestic hot water system (SDHW) for Canadian weather conditions.

The conjunctions of solar thermal collectors with DWHR units are found most beneficial in Edmonton. Subsequently, the models are used to investigate the performance of similar systems for five major Canadian cities of Halifax, Montreal, Toronto, Edmonton, and Vancouver. While the addition of the DWHR and the evacuated tube collector in House B would result in an annual energy saving of 1771 kWh. The addition of the DWHR and the flat‐plate solar thermal collector would result in 1831 kWh of annual energy saving in House A. Both systems are modeled in TRNSYS, and the models are validated by experimental data. The second SDHW system in House B includes an evacuated tube solar collector, an electric tank, and a DWHR unit. The first SDWH system in House A consists of a flat plate solar thermal collector in combination with a gas boiler and a DWHR unit. Both SDHW systems are recently installed at the Archetype Sustainable Twin Houses at Kortright Center, Vaughan, Ontario. In this paper, the performance of two solar domestic hot waters (SDHW) with drain water heat recovery (DWHR) units is investigated.
