Comprehensive Evaluation of Using Solar Water Heater on a Household Scale in Canada

Canadian researchers are now trying to exploit much more energy from solar sources, hydropower, wind, and biomass. Given the fact that reducing the carbon pollutant level is a political priority in Canada, this paper studies the feasibility of providing sanitary hot water and space heating demands of a four-member family in 10 provinces in this country. The feasibility analysis was performed by...

Experimental Analysis of Solar Water Heater Using Pulsating Heat Pipe

Solar energy is used for solar water heater in domestic and industrial purpose. Pulsating heat pipe is a fast responding, flexible and high performance thermal conducting device. The CLPHP system described in this study relies on the natural forces of gravity and capillary action and does not require an external power source. The flat plate collector consisted of a 2 mm thick sheet of Aluminum ...

Experimental Study on an Enhanced Performance Solar Water Heater

The paper presents preliminary results of an experimental study on solar water heater with full width and 75% twisted tapes as heat transfer enhancement device. The study shows that the thermal efficiency due the use of the twisted tape increases by 4.5-8%; higher for the 75% twisted tape. Keyword Solar water heater (collector), tube-in-fin, twisted tape, thermal efficiency, performance enhance...

Geyser Pump Solar Water Heater System Modeling Design Optimization

Solar thermal water heating systems reduce household energy bills by using the free solar radiation provided by the sun to heat water for residential needs. In order to eliminate the need for electricity to run a pump to drive the fluid circulation in these systems, fluid buoyancy effects can be employed to move the fluid from lower elevations to higher elevations. There are several operational...
