Hi John

I came across your excellent articles while researching a shower problem via various sites, and I'm hoping that perhaps you can help.

My son has recently moved into a new (to him, IYSWIM) house. The house has been renovated by the previous owners and has a combi boiler. The problem is with the shower in the bathroom which is a "Victorian" style (i.e.brass & porcelain) and which although apparently "thermostatic" does not control the water temperature at all. The temperature varies randomly, but always too hot for comfort, no matter what the control setting is. I should mention that the control is a single lever for both flow and temperature.

The markings on the shower mixer valve indicate that it is a "Force 10 Thermostatic". I am unsure if this is the name of the manufacturer, or the model. I cannot find any references to this name on t'internet at all.

I have dismantled the valve, and tested the thermostat capsule in a bowl of hot water and it appears to operate OK.

Have you come across "Force 10" before? Any ideas what to do next?

TIA

Peter: I suggest you ask this on the newsgroup as you will get responses from people with a wider range of expertise and experience than just mine --John Stumbles 11:18, 31 July 2007 (BST)

Thanks John. I've posted a couple of times but nobody has come up with the answer yet! Thanks again.

This has been discussed on the group before. AIUI a standard combi and standard thermostatic shower are incompatible. If you think about how the thermostatic shower controls temp, and how this affects a combi you should see why. The ng is the place tho. NT 00:09, 1 August 2007 (BST)

DIY Heatbank

Hi John Great easy to follow articles. Re the DIY heatbank, would you now suggest any modifications to the original? I'd particularly be interested in how best to link 2 100L standard direct cylinders together to form one store. Ian

I've no experience of such an arrangement so I'd suggest discussing it in the diy newsgroup. --John Stumbles 21:45, 20 November 2007 (GMT)

Done a picture upgrade...

See Motorised_Valves. I added a link to the fill zoning article as well since that now has a nice diagrams for all the various plans along with detailed wiring centre schematics etc.

SENTINEL X100 INHIBITOR

Hi John

I read with interest your test on inhibitors. We are currently investigation Sentinel X100 which appears to have altered it's dosing rate by 30%. Do you have any records dating back to 2004 when you carried out the test? Do you have the original paperwork showing the dosing rate at 100 to 1?

Thanks
