Unexpected boost to our Solar thermal
Had solar thermal installed 15 years ago then 9 years ago had solar PV. But decided not to install an i boost as we were already getting hot water even in winter it would raise the tank temperature 10 degrees. However we would only get a full 60 plus tank for about a month or 2. Then after getting a smart meter fitted in February we realised how much our 2.5kW system was exporting so brought the i boost. This has transformed the solar thermal which now heats quicker and even in March we have had several 60 degree full tanks. Conclusion I am kicking myself that we didn't do it earlier.
