Ok, will give it a go.... I was worried that "The connecting link between terminal 3 and 4 must not be removed" in the VRC 430 manual meant it wouldn't work.... But maybe they meant ""The connecting link between terminal 3 and 4 must not be removed, unless you also have a separate room...

There are 10 room stats, each one controls a TRV on the rad in the room that it is in. Each room stat then talks wirelessly back to the main control unit, which connects to the current boiler on it's stat connection. According to the ecoTEC install manual, the link between terminals 3 and...

Hello, I am having an ecoTEC plus 831 combination boiler fitted as a replacement boiler to a central heating system that already has wireless temperature thermostats and thermostatic radiator valves in each room. There is also a central control unit for the wireless room thermostats that...

Hope this post doesn't break any rules, but can anybody recommend an honest & reliable heating engineer that covers Northampton? I've an old Thorn boiler that's started to leak water from the heat exchanger, so think that it's time to replace it and take the opportunity to upgrade to a more...

Thanks for the reply Tony. If I connect the control to both the boiler and the pump, will that not also switch off the HW too though? For the programmer, do I need anything special to take into account the difference between the once a day and twice a day setting on the boiler? I...

Hello, I have a very old Olympic Thorn boiler (38/50 model I think), that's still going strong on a gravity HW / pumped CH system. It currently has very basic controls on the boiler itself: a thermostat a switch for once a day / constant / twice a day a switch for HW / off / CH & HW...

Yup, I did that, got them about 450mm off the ground. Another good point, it's not 100% certain I'll need a pump, I need to wait until there's some water in the butts to test with :lol: But, I had considered the pump pumping nowhere and would be fitting a fluid flow switch to detect if...

Thanks for the quick reply bas. I probably made it sound a bit grander than it actually is, think 2 big plastic water butts (400l each) and lots of guttering / pipwork off all available water gathering surfaces. It's all plastic, no metal work (aside from screws). I'm considering a water...

I'm planning on doing the following and would like some advice on whether what I'm proposing is acceptable. I've just put up a shed in my garden and need to get an electric supply to it. It needs lighting (3ft fluorescent strip inside and a PIR security light outside) and half a dozen...
