solar thermal just for hot water.

[gjcone44]

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



The Ecotube performance versus their five main competitors - based on performance output per kWh per m²[/h]

*	kWh/m²	Relative Performance
Ecotube DF 100	727.00	100.00%
Baxi DF100 20	704.02	96.8%
Kingspan DF100 20	699.11	96.1%
Viessmann VT200	682.14	93.8%
Valliant VTK 1140	642.89	88.4%
Worcester Bosch T3	539.84	74.2%

As you will see from the adjacent
chart the Ecotube DF100 has been proven to be the highest performing panel in the UK.
