    Hi all, I’ve prepped a bedroom ready for lining and painting. Have some rolls of Erfurt 1400 Red label lining paper along with a bag of Solvite All Purpose adhesive, paper instructions say to paste the paper….

    Vaillant VR65 / vSmart & zone valve on constantly

    I have a Vaillant ecoTEC 418 / VR65 / vSmart control and just noticed one of the Honeywell zone valves is on when there is no CH demand showing at the boiler (S.31) or scheduled. When DHW is requested via vSmart, the CH zone valve closes and the DHW valve opens and the pump runs. When finished...

    Air vents & gas fire with open chimney

    A living room has a open flame gas fire with open chimney, there is an air brick in the same room with a missing cover. As the fire has chimney, is it okay to buy a vent cover which comes with a fly screen? - Many say not suitable for gas fires but does that still apply if there is an open chimney?

    Hi, I have a ecoTEC plus 418 boiler with VR65 and VSmart controller. I’ve just switched it from summer mode to winter and found the radiators not heating up. A quick bit of diags shows: - S30 on display - No radiator symbol displayed - d.23=1 on boiler (winter mode) - d.8=0 (no heating demand)...

    Vaillant VRT392 not calling for heat diags

    Hi All, I have a Vaillant VRT392, VR65 and ecoTEC Plus 418 all connected via eBUS. All was working well until today where I found that the DHW works (i.e. it's calling for heat when asked via the VRT392 and is showing the symbol on the 418) however when changing the room temp to heat the...

    Electric lock tripping PSU

    Hi All, I have a 240v Access Control Power Supply which outputs 12VDC / 3A via a built in relay, connected to a 12VDC electric lock (which has two solenoids & a 1n5408 diode in parallel across the terminals) and a 12VDC RFID keypad. I purchased these as a project to help me learn about RFID and...

    Vaillant vSmart to replace VRT392

    I still have my Vaillant VRT392 which despite it's poor UI, lack of easy access boost for DHW has been okay for the last few years. SHMBO keeps talking about Hive/Nest and their ability to control via an App, as a technology lover myself I too was interested but as we would lose the modulating...

    How to unblock a 1200 Stelrad Elite Double Panel Rad

    Hi, Using a IR thermostat I noticed a couple of my radiators were reading around 50C at the top and only 40C in the middle/bottom. I have 10mm microbore downstairs so I decided to give the system a clean as I assumed the delta between top/bottom was due to magnetite. After emptying the...

    New bathroom taps - pipe extension?

    Hi all, I have some new taps to fit on a existing bathroom basin, unfortunetly the new (flexible) tails are slightly too short to connect to the isolating valves attached to my 15mm copper feed pipes! :( I've been looking on screwfix/toolstation to identify some kind of suitable...

    Mould / 'cardboard' like substance in header tank

    Hi, Just had a look in my header tank and found the following: The white bits looked like 'mould' and the brown was what I could only describe as like soggy cardboard (in texture) and about 1-2mm thick covering almost 99% of the water surface. Does anyone know what the 'cardboard' like...

    I have just flushed all my radiators and noticed many of the lock shield valves were fully open. I have a IR thermostat and after checking the rads there is around 2 degres between flow and return. I've read how to balance, to try to get a 13 degree c difference between flow and return...

    Vaillant VR392 VR65 VR10 Controls Upgrade

    I recently had a ecoTEC Plus 418 boiler installed which was connected up to my existing Honeywell controls (Y6630D Room Stat, CF9000 Programmer, Tank Stat and 2x2-Port valves) and open vented system / cylinder. Vaillant suggests their controls will be 5-10% more efficient, to take advantage...
