Thx, The entire system is new including the clock, HW and CH valves. thx

You're right sxturbo, I was holding fire with involving the insurer to allow the builders all opportunity to sort this. I seem to be spending all of my time chasing my tail. Maybe we should agree to get an independent CH engineer in to sort all of these problems with the threat of recharging...

This is a refurb of the house being carried out by a builder appointed by the insurer. Both the plumber and electrician are subbed to the builder. Sorry this is complicated, I kept the info to a minimum for simplicity. It seems to be the builder muddying the water hoping that I get board and...

Hi, This is another problem unfortunately.

Hi thanks for the response but is a gas safe engineer qualified to do electrics as well as plumbing? I think yes? Fortunately, the company who installed this system are considered professional and I have no doubt about it being unsafe. Its just that the plumber seems to have too much work on...

Hi, I'm having a great deal of problem getting the Gas Safe Heating engineer back to repair an intermittent problem with my new heating installation. Basically, an electrician carried out all the electrics and the gas safe engineer has done all the plumbing. I now have the problem that each is...

Sorry for the confusion.... The inverted U-pipe I'm talking about is the 15mm pipe coming out of the carpet (left of the pic) by about 400mm, goes over the Honeywell CH valve and then goes down again to connect to the outlet pipe from the cylinder coil. It's got the cable to the cylinder...

This pic best shows the inverted U pipework from the heated towel rail..

So the towel rail comes on when the HW or CH is switched on with the current arrangement. Surely the system is plumbed correctly then? My syphon question query refers to the inverted U pipework which forms the return pipework from the heated rad. Rather than connecting this rad return to the...

Added a couple more pics to show pipes which perhaps are obscured as I may be confusing people. As discussed earlier, this towel rail is designed to continue operating when the CH is turned off during summer months to keep towels warm. You can see from the earlier pics where the return from this...

Surely, the set up is correct then? The towel rail shouldn't be connected after the HW valve as it would then only heat when the HW is being called for? I'm obviously missing something here? This makes the current set up (above pics) correct, doesn't it?

Sorry, I think I'm being a bit dense and don't understand what you're explaining.... I thought the the towel rail IS connected before the HW valve so will not come on with the timer. This supply pipe also goes to the CH valve. Is that not correct? Sorry to be a bit slow....

Is that wrong? Where should the supply pipe to the towel rail be connected? The supply pipe to the towel rail connects from the main pipe from the boiler and is located before the valves to the HW and CH.

Hi Cross thread, you appear to be confident that the towel rail circuit is the cause of the reverse circulation and say its acting as a by-pass. Apologies for my ignorance but what is it by-passing?

Pics of pipework in airing cupboard as requested. The small bore pipes coming out of the floorboards on the far left are the pipes for the towel rail.

Heating zone valve isn't being bypassed which is something that the plumber keeps telling me to avoid talking about reverse circulation. Something else I notice is that the upstairs bathroom has a heated towel rail which is fed directly from the boiler and not through either the HW or CH...

I have a reverse circulation problem on my sealed s-plan system with the upstairs rads getting warm when the CH is off/HW on. I'm getting no solution from the plumber who installed the full system but I'm sure he well knows what the problem is but hopes that I get fed up and go away...

Hi, I have an unvented S plan system with 2x 2 port valves. Four weeks ago I stopped receiving hot water which seems to be an intermittent problem. The CH is working fine but the HW valve isn't powering and no HW water is getting to the cylinder coil. I called the plumber who left after checking...

Pics show everything you can see in the airing cupboard. Boiler is directly below in the kitchen on the ground floor. The pipes to the far left coming out of the floor is the flow in and flow out for the rad in the bathroom on the HW circuit. All the rads connect to the return pipe to the boiler...

Aah, thats great to know. For information, when you have a bathroom rad fed from the HW supply where do you normally connect up the rad return pipe to??
