The solar water heating systems are usually designed as half of the average household hot water demand. Energy Savings Trust Fund recently study - the largest of the ongoing research of Solar thermal collectors- found that more than 88 sites, the solar hot water provides hot water as much as 60% of the families an example - but also found that 9% or more. Median 39% of all households.
The collector field test run over the course of the year from April 2012, the measurement delivered heating household water, the energy required for the pump system and a control system of the operation of the electric energy, and the energy delivered by the reserve heat source - in all solar water heating systems need something. Is determined to be the required level of the water, insulation resistance and heat resistance performance of the main factors.
Industry guidelines and standards for a thorough review of the Energy Savings Trust Fund requirements, fully resolved to ensure that all the problems found in the trial, to get the maximum possible revenue from their investment in the households of the solar water heater.
