New Radiator Problems

KPike

Hi all
I have experienced a problem and really not sure what to do...

I recently moved into my new house.
I replaced the boiler as soon as I bought it to a Baxi Duo Tech 33.

I felt that the house was lacking radiators, it had 1 in each of the following rooms:
Living Room
Dining Room
Downstairs hallway
Bathroom
Bedroom 1
Bedroom 2.
I felt that it needed one in the kitchen and the upstairs landing.

I promptly went onto findatrade and someone contact me with a fair price to install 2 new radiators, total cost of £270.
He and one other then came out to install them.
They were here around 3 hours and installed a radiator in the kitchen and the upstairs landing.
About 10 minutes after I left, I put the heating on to see how much of a difference it made. About 10 minutes later I noticed that none of the radiators were on. I checked on the boiler and seen error messages and that the pressure had dropped to 0. I then opened the inlet valve to fill with water, to where the pressure wasn't going up.

I called him and he came back within 20 minutes to have a look. He explained that there was a leak in one of the pipes that they laid and it has now been repaired.
That night, I noticed that water was coming out from my light fitting downstairs in the dining room (this room is slightly below the radiator upstairs and boiler upstairs) and dripping onto the floor. I immediately turned off the light section from the fuse box and took down the light fitting. I called the plumber and he explained that it was probably water coming through from the leak earlier.
He came out the following morning, drilled holes in the ceiling and collected the load of water with about 4 buckets. He then filled in the holes, left and explained that it will all be fine.

This was around 2 weeks ago. Since then I have had to bleed the new upstairs radiator 2 times as it has filled with air. I have noticed that the pressure is dropping on the boiler, not drastically, but gradually and have had to fill it back up twice. Also, the radiator in the kitchen is cold at the bottom and warm at the top.

I have told him this and he said that it is normal for air to fill in radiators over time.

The thing is, since I had my new boiler, the needle has NEVER moved off the mark where it was the day before (obviously without the heating/water on) and it had never needed filling or the radiators never needed bleeding.

Any suggestions?

Thanks

I think, on the basis of what you've posted, I would be getting a different competent plumber out to check the installation.

I wouldn't want the plumber who can't do something as simple as fit some new radiators without refilling the system and checking for leaks and checking the boiler pressure anywhere near my house again!

I hope you've not paid in full!

The chump has left you with a leak somewhere. Combi heating circuits will always find the smallest leak because they are pressurised.
