I have a glow-worm solar panel installation for heating hot water via two panels on the roof. I think the product brand is 'clearly solar'.
The system is 6or 7 years old and was installed in our house before we bought it last year
There is a pressurised boiler and a separate programmer.
I have the instruction booklet, which I don't find all that helpful, but here is what I'd like to achieve.
That I can set the desired HW temp to be say 50 deg, and that if there is 'solar gain' available, the system will alert a pump to cycle the HW via the roof panels to heat up, and it would do that independently of firing up the boiler to reach 50 deg. The boiler would only kick in IF it is within the hours specified only for the boiler to kick in.
Here's maybe a better more explicit description; I want to set the desired temp to 50 deg. From 8am to 8pm (aka all year round) if there is solar gain to be had then I went to make use of that first (I.e.in summer boiler heated HW may be avoided).
If however no solar gain is available, then the boiler should NOT kick in unless it is between my specified time just for the boiler, which is say 4pm-8pm. (I.e. in winter boiler heated HW will be kept to a few hrs).
The way it seems to work for me is that I can only state I want a boiler temp of 'x' and that the heating time range will get either solar gain to heat the water or if that is not available it will fire up the boiler. Not what I want if I am setting a time range of 8am-8pm, as it means the boiler would be topping up the HW temp all day.
I have a traditional looking HW and CH controller in the house but this does not seem to work for the HW. It seems to be overidden by the solar controller.
Hopefully I have explained this ok. Thank you for any advice.
