Pros: Quality product. , Smart looking
Cons: None so far
An excellent top quality product that works very efficiently.
I was a little concerned about the reducing valves supplied, as I have 10mm pipework on my central heating system and wasn't too sure how efficient they were.
Rest assured they worked well with no problems.
The price at Plumbworld for this item is also excellent
Pros: saves energy and money
Cons: heat setting difficult to see, heat setting would be better shown as degrees c
This is an excellent product. I used to have the radiators on a low setting in the bedrooms but sometimes they would still make the rooms too warm. These thermostatic valves are great. I tested them yesterday afternoon when the temperature in the bedroom was 18 degrees C. With the valve at the 3 seting the radiator didn't get warm at all. I tested it again last night when the temperature in the room was 12 degrees C. the radiator came on full for 15 minutes but when the room reached 16 degrees, the radiator turned off even though the heating was still on downstairs. This will save lots of wasted energy and keep the rooms at a comfortable temperature. I'm sure they will have paid for themselves within a couple of years
They are also very easy to fit. I fitted them myself in 20 minutes while flushing the heating system.
Pros: easy installation
