Central Heating Pipe Power Jetting?

Perhaps a topic for discussions, due to the changeable and cold weather, and how we all like to keep warm?.

Having had problems with the central heating over the past few months, which as resulted in having a circulating pump and boiler fan replaced. Today having had no heating etc for a few days, the engineer (very busy) called and stated that the problem was actually sludge in the system.

He as arranged for the whole system to be power flushed, and other pipework and some fitments replaced next week.

Have you had this done, did it make a vast improvement, and were there any later problems. Not forgetting how some of us neglect our central heating until things go seriously wrong?.

lotvic Depending on the design and how many changes since its been fitted you may have air traps these will first need to be cleared, turn heat up to full then start bleeding from rad farthest away from boiler, you may need to do this several times. balancing takes time and you need to know how to do it. Hot rads need to be only turned on enough for them to heat up if you do not have rad stats

Yes must have as I don't get complaints from them as to how cold it is

Where's that edit facility when its needed, to be honest i hadn't noticed the error.

FruitBat and Bingalau - perhaps it's just a case of the Missing Apostrophe with parents and parent's that would have made the difference..... not in the Birmingham area by any chance?

Balancing rads is a long drawn out process. I did mine after the flushing work mentioned earlier. I have a temp probe for my Avo which made it easier. Good guide here.

What I was fed up with was the 'promises, promises' 'we'll leave it running right for you' from engineers and BG.

I don't have prob with me balancing the rads - once I've got the air out. I've marked the valves etc and about got them to rights, my open vent system has all drop-down rads so air locks can be a problem. Anyway it seems to be about right now.

Just as an aside. I had a problem with my new Worcester Condensing Boiler. Although its output was supposed to be greater than my old thirty plus year old one the house did not feel as warm.

The solution appears to be running the pump at top speed, a bit noisy but at least the house is warm.

It is difficult to be exact but it would appear that the gas consumption has only been marginally reduced. Need a few more years use to get definite confirmation.

More like dyslexic fingers or "Norman Collier" wireless keyboard that misses out letters / symbols as I type.

We had our central heating power flushed 2 ears ago, it does make a differnce in temperature and how warm it gets.if you feel around your rads you may find cold spots here and there, even if you try to let the air out, you wont get rid of all the aitr until you give it a good flsuh and then bleed the rads

Reading some of the comments it would appear that we are in the hands of the experts on the day (mid next week), as to whether the problems we are having have been resolved, and whether the 'sludge' and power wash was the culprit and remedy.

A few things that I have learned this, is how the companies advertising their services usually with a 24/7 emergency back-up, all seem to be either busy or very selective as to whether they turn up or not. The other noticeable thing was the price of parts. Doing a little research usually results in the same items being available at a more competitive price than perhaps other sources. Even the price of a brand new same/similar boiler can vary by a few hundred pounds, depending again on sources of supply.

In my general view, I suspect some of these companies or people, know they have you by the 'curlies', and use their 'expertise' as a bargaining point. I wonder how many unemployed plumber's or central heating engineer's or indeed professional's in other trades, could perhaps fill some of the gaps left by others?.

Will tick this as resolved, and hopefully return back to finding or fighting for a space in front of the lounge gas fire :O(

Spuds. You will find power flushing can be a messy operation, lots of black grungy water about. I hope they can do it all without too many pipework disconnections, to do it thoroughly will take several hours and a few changes of water.
