Ah, great idea! So this is opposite to a trv, flow increases as temperature increases. Thanks for shareing, i'll definatley be fitting one of these. Not so much a problem in winter when the plate heat exchanger is already hot but in summer there is a whole sink bowl full of cold before the heat arrives.
You don't really need this restrictor - you have one on the end of the pipe - a tap. Open the tap a small amount until the boiler fires fully and is able to match the flow you require - then open the tap as normal. Same applies to the shower. You will waste less water this way and use gas more efficiently.
Is this the same as the 'wax capsule stat' that was fitted on old Potterton Puma combis years ago? I have no idea if they work the same way, but I remember they were fine until they stuck. Then customers would call me out with symptoms similar to scaling up - that's what even some heating engineers thought. Sometimes (rarely) you could tap the capsule with a spanner to free it. Like I said - like everything else...fine until it goes wrong. Then, rather than it saving the customer money, it costs, instead.
Same boiler I think as what I have is this a greenstar 36cdi out of curiosity what do you run your flow temp at. As I live in a old stoned house and a flow temp at 75 doesn't seem warm enough
If your flow temp is at 75 and your house is still cold considering calling out a pro to find out why. I live in a 1930 built house and 65 is plenty for me even with 12 foot ceilings and timber suspended floor with air bricks. If 75 isn't getting warm you have a issue I would imagine Personally I would think limescale and corrosion/radiator rot is probably the cause if system is old (10+years) Do you have a magnetic filter under the boiler? That and some inhibitor would probably help although its difficult to tell without seeing the system Good luck!
System not old house is big radiators are hot just seems it takes a long time to heat the house boiler and System has been checked and serviced and all rads balanced and no air locks your lucky to be able to run 60 flow temp
Yes have a magnet and inhibiter been checked and topped up. Flow temp at 65 the house takes hours to heat up I'm thinking maybe rads are undersized for size of house
