I'm not really at the point of connecting the rads (or the boiler for that matter). Imaging a water pump connected to a 30 metre loop of 22mm pipe - nothing else (except a flow meter). I'm getting a flow rate of 26 LPM going through it, which I don't think is very much. Obviously I'm going...
Thanks Picasso, That's the nearest I've got to solving the problem. I need to have a closer look at it, but the thing I couldn't see anywhere was 'what is the resistance per meter of pipe' It gave the equivalents for each type of fitting (eg things like 'an elbow is equivalent to 2 meters of...
It's about 10 radiators. Used to be heated by an oversized 75KW Oil Burner. Flow temp is 55 degrees.
However, I'm just trying to increase the flow rate, so really it is just the water pump and the 30 meters of 22mm pipe that are involved - when I do the flow measurements the heat pump is...
The boiler is a Daikin 16KW Altherma Air to Water Heat Pump. Heat pumps are different to gas and oil in that they only generate water at a max temp of 55 degrees. Without going into the way that they work, it is important that I get a good flow rate through the heat pump otherwise it attains...
I am having flow rate problems with my Central Heating. I have a CH boiler in the garage, which is 15 metres away from the point at which the pipes split to serve various zones in the house. My flow rate with all radiators open is 20 litres per minute
To try to pinpoint where the problem is...
