We recently had a boiler installed (Veissmann 050W) and the installer has placed it on a big piece of chipboard and ontop of that is a boiler bracket. He said they are all installed that way but looking at reviews for this company I am seeing the same boiler, neatly installed onto the wall...

As in bleed the rads and top up the boiler? Yeah.

We only have the small +/- ones from the 80s but they are all on full. I have opened up one of the upstairs Lockshield valves half a turn and that's helped - some are up to 50 now. Though not sure it was me doing that turn or the fact it's now been 2 1/2 hours and they had caught up. The 2 big...

Combi conversion from gravity fed system - paid the company 'heatable' who I assume pays the installer a cut. I did not pay them direct or a hourly fee, I simply paid for a combi conversion.

So I have run a test with an Infrared Thermometer - heating on for 1 hour. Downstairs all eventually all heating up at different times but after 60 mins these are all now between 54-57 degrees (boiler flow is set to 62) so that seems OK. Upstairs are ALL 42-45... I will call them up and hope...

Veissmann 050-w Rads downstairs are now getting hot, but upstairs lukewarm at best. He indicated this was normal and just air. How long do I leave it this way before calling back - I'm aware he's 4 hour round trip away so as disappointed as I am in some factors of the install - I don't want to...

Had a new boiler installed and everything went to plan except all 13 of our radiators is cold at the bottom. Upstairs they are worse and only warm at the top. Heating has been on for 3 ours at a 65 degree flow temp and we’ve done from 14-15 degrees in that time. Before the install I went and...

Not my industry but why would they not include these controls as standard?

Update from Vaillant on this: ---- Good Morning, Thank you for your email. The boiler will only be able to tell the difference between heating and hot water when installed with our controls. Kind Regards Technical Advisor ---

Here's the spec sheet which mentions it.

I am assuming that is the case. I have called them and spoke to 3 people but they literally have no idea; one is convinced I am talking about a combi as "the water & heat output would be the same" despite both website spec sheet on installer website and manual suggesting otherwise. Off to a bad...

It still says condition: controller not connected and seems to allow separate water temp...hmmm. Confusing.

Thanks for the tip!

Sorry, yes we have a small expansion tank, it's just to the right of the first tank in the photo. Hard to see but it's there. We have a main bathroom with bath & shower and an ensuite with shower.

Looking to replace my CWS tanks in the loft, they are 35 years old, full of silt, have a broken float and have stretched so much now that the makeshift covers are not fitting well and close to falling in! We have 2 main CWS tanks - approx 56x56x108 - I make that approx 75 gallons capacity...

I don't have the boiler yet, but looking at the manuals it suggests you can seperate HW and CH temperatures. Frustratingly it makes no mention of needing their thermostat. I'll report back next week.

The cylinder is brand new so hopefully fairly efficient. 1.7kw per 24 heat loss if that means anything. 160L I will see how we go, and if desired we can always buy the Vaillant controls. I assume the setting on the boiler itself for heating temperature and hot water temperature is the same and...

Darn! So I assume when heating the hot water cylinder, it would do so at 18kw rather than their advertised 25kw? If this is true I am unclear how it would modulate as we'd not want that on water, we want it to heat up as quickly as possible - especially when 4 people all want a bath from our...

We are getting a Vaillant ecoFIT Pure 418 next week and hope that it will work with our existing Hive system. From their litterature the boiler will give a max 19kw of heating output and 25kw for domestic hot water. This confuses me as it's a heat-only boiler but if true it's perfect for us as...

By stuck I don't mean it won't turn; it turns freely without doing anything. I believe the inside has snapped off in the closed position. T he adjustable is what caused that in the first place :LOL:
