I stopped the purging and thought I will just re-do the pipes tomorrow, but then when I turned on the heating, the rad actually got quite hot, even though I still see some air bubbles when I connect...

I have taken your advice and now I have the water flowing into a sink instead of a bucket. So I'll leave it draining very slowly for a day or so and see if the air bubbles disappear, before re-doing...

yea basically bleeding into buckets. I suppose it would be better to bleed into a drain as you say. The thing is that I have to keep increasing the water pressure in the boiler every 15 mins or so,...

still purging the air, One of the pipes in the garage that feeds the 2 cooler rads goes down about a foot, then up again, which might make it more difficult to get the air out? Do you think I should...

Recently I added a few rads to my OFCH system and 2 rads don't get hot.

I have been letting air out of one of the cold rads, hooking up a plastic tube to the bleed nipple and placing the end in...

I have spent ages bleeding the 3 rads individually. While Im bleeding they do get hot , but when I finish, they just return to normal, almost cold.

But my main question is: should this type of...

I have added a few new rads to my home heating system and 3 of them don't get hot. These 3 rads have new mono type valves (which means the flow and return are together connecting to one side of the...

so you would connect mains to pins 2 and 10 AND also one side of mains to pin 1? hmm... seems strange to connect the mains twice. But...?
I may end up calling the manufacturer. There are bigger...

a complete manual? All I got was a small folded piece of paper with print and diagrams, compressed to a tiny size and impossible to make out. I did email the company but no reply yet. I am assuming...

BTW the instructions in Spanish are not an issue for me, just the lack of clarity. About the second 220 Volt connection: I think it's probably supposed to be connected directly to the pump? And the...

due to the hopelessly inadequate instructions I have no idea how to make the connections - I know that *one* of the mains 220 v wires connects to pole 10. I wonder if the other goes to 4, which...

I got this water level sensor here in Spain for a well, and you would need a microscope to read the diagrams etc. So I was hoping that someone might be able to help. I have attached photos of the...

yes there is an exànsion tank built into the combi (condenser) boiler which is situated down in a garage under the house. And there is insulation on the attic pipes. At first when the last rad was...

The last 2 rads are on the same branch (15mm) from the main pipe (22mm), but for the last rad the pipes detour for about 12 meters up into the attic, across, down etc. to the last rad. I have bleed...

It's an oil combi burner, using water in a sealed system around the rads. I did hear something before about "balancing" rads and I thought it would be logical(?) that reducing the heat in the hottest...

Yea...makes sense. BTW it is a two-pipe system. Just turned on the system for the first time today. Seems fine except that it takes the last rad (upstairs) quite a while to heat. Maybe because the...

I heard that turning off some rads in a house is not a good idea. In this case there is a combi oil boiler (sealed room type), with about 13 rads, and a somewhat oversized boiler. Each rad has a...

About the weight of the tank - In my case two 1 meter beams will be inserted into a principal brick wall which is about 14 cms thick, taking about half the weight of the tank, and then two other...

yea, I know 500 lts is a lot. I wanted a smaller tank (350 lt) but not available just now at suppliers. My idea is to fill it to about 300 lts. Of course if one day the floating switch is faulty then...

Hi, I have a new 500 liter plastic potable tank to be installed in the attic and I need to drill a hole for an overflow pipe (which is 32 mm diameter).. What kind of drill bit is best and what...

So bottom line is that the only "damage" that might result from using the 52 meters of 3 cm downpipe plus the existing 58 meters of 2 cm pipe, would be that the 2 cm pipe could burst or some...

But what would be the exact reason for fitting the tee with pressure gauge to connect from 3 cm to 2 cm pipe. What would the pressure gauge do?
Would it be preferable to use 4 cm pipe from well...

Actually I already have the pump. Yes, I just want to fill a simple water tank in the attic which has a floating switch to control the pump.
Would it be of any help to use 3 or 4 cm pipe just from...

I am about to install a new Franklin 4" pump (mod SM-3-22) in a 60 meter well.
The water outlet on the pump is 4 cm diameter but the existing buried pipe from well to house is 2 cm diameter. Would...
