Shower for use with solar panel pv heated hot water tank

Since you need to replace anyway, we can certainly recommend Aqualisa, the old ones we replaced were still working and were about 33 and 35 years old!

And we still have one original from when the house was built in 1988, still working fine, never gone wrong at all.

The one we replaced at 31 years was the one that had the most use, it needed a new thermostatic cartridge after about 20 years.

We are however in a soft water area.

We did not go for anything fancy when we replaced our showers, so our Aqualisa ones were around £225.

When we were using the system which sent power to the immersion heater, we were on deemed export, which only paid us about 6p per kWh, our installation is from 2012 so we are on a high FIT payment as well.

Once  we got a smart meter we could see how much we were exporting so changed to metered export and turned off the diverter,  but when we were using it, in summer, our HW was always VERY hot.

As long as gas prices are less than what we are paid for export, that will remain the case.

I would agree with the post above, no point in spending on a new shower mixer if you can top up with gas when required.   Are you sure the Triton needs water at 65 degrees?

My guess is that there might be some misunderstanding.
Often it is recommended that hot water tanks are heated to 65 degrees, to eliminate the possibility of Legionnaires disease. So maybe the Triton literature recommends 65 degrees, but it seem unlikely that it needs to be that high for the shower to work ( just a guess though).
Anyhow in reality Legionnaire problems in domestic systems are rare, especially if the water is used regularly.
Some sources say 60 degrees is fine, and is less likely to scald you coming out of the tap.
