Thanks to previous posters who informed me that the valve on the return to my boiler is called an injector tee...I'm learning slowly! :-)
I got the Baxi Bermuda 552 manual in the post from Baxi today and one paragraph states:
The flow and return connections to the boiler MUST be made as follows:
(i) The water spreader adaptor and the injector tee must be fitted in the lowest of the three tappings with the branch facing straight down. It is acceptable for the branch to be angled at 45 degrees either side of this position.
My injector T is angled so that the branch is horizontal...i.e. at 90 degrees to the recommended "straight down" position.
Obviously the boiler has worked for years like this, but I have always thought that it takes a long time for the hot water to heat up.
Any comments?
