Hah! --- I know ............ but I don't think the good lady will be very pleased with the disruption ESPECIALLY as there wasn't a problem before I did something that as it turns out wasn't necessary in the first place! :shock:

Blimey! ----- would this be with fairly high main pressure? Ours is not particulary high but for some reason it seems higher now! Also, I know there's a length of blanked off piping upstairs - previous owners were going to convert small bedroon to ensuite but never got round to it but had the...

OK & thanks ---- I guess it was an easy 'try' just to turn of the water, leave the taps open & see what happens. Razor --- thanks, I'll try what you say. The pressure does seem different since I did what I did. Seems alot higher initially and then settles down ok. Boiler doesn't seem to...

Had a VRT 50 for a few days now and it works well with the Ecotec 831 combi and 130 timer. It maintains a much more stable house temp than the anologue dial type stat. Vaillant user instructions I find is not the best! Firstly the gumph says it 'can' be set to modulate the boiler depending...

Right ok & thanks for the pointers ---- but any ideas on the boiler now behaving differently. May be just a coincidence.

Somehow a build up of air has occured in our water pipes manifesting itself in a 'trombone' like sound coupled with vibration in the cold taps when the upstairs lavatory cysten concludes each refill. I turned off water at mains, switched off combi boiler and opened all taps. Air could be...

Anyone able to help very welcome please!

Thanks again Dave Seems straight forward enough. rather than lay a new cable can I use the existing one that the anologue stat is connected to and disregard the earth wire. --- I know this is mains live so I will need to unplug the boiler at the mains. The ebus connections seem easy but I...

Thanks Dave ..... ..... Is connecting via the ebus cable straightforward? The literature says it must be connected by an approved installer so it looks like I will need to have this done professionally ---- no problem with this as I'd prefer it be done 'properly' Guess it's a fairly...

We have a Vaillant ecotec 831 combi with the 'simpler' timeswich 130 and a honeywell non digital dial type roomstat. I am looking to replace the roomstat with a vaillant VRT50 programmable roomstat to provide a more stable house temperature. According to the Vaillant website the 130 & the...

Thanks alot stem -- very helpful

Last year we had our heating system totally upgraded with a new combi system inc all new rads. We also had a new roomstat but stayed with the 'mechanical' dial type unit. We found this ok but it has quite a wide temp variation between on/off. I've heard the digital ones will maintain a much...

I am in the process of topping up my existing bog standard 100mm loft insulation with 200mm Knauf Space Blankets. This will give 300mm in all and should raise the insulation level considerably. This product is very easy to lay being encapsulated and I assume it's thermal qualities are...
