hi i am a spark, who has fitted solar pv on south facing roof.i am now looking at getting solar thermal, to supply my hot water ( just for upstairs, one shower and 2 sinks)have got combi boiler worcester, 30cdi. but dont want to get involved with that. have 2x2mts, on south facing roof, but also have a hip roof facing west, would like to fit panels / tubes, on both have plenty of room in loft for 250l tank, question is would you fit to separate systems, to feed a twin coil tank or would it be better to link the 2 together, and supply single coil tank, the solar experts advice would be appreciated :25:

Use Ecotube you'll only need 6 tubes, Even on a correctly designed system stagnation will occur it won't damage the system but will have an effect on the glycol so always use a good quality one

They are efficient I was suprised you need so few tubes but they are massive must be at least 100mm but they do work well
