    Vaillant ecotec 24 clicking

    My Vaillant boiler has been installed and operating well for 26 months. Recently it has started making a short clicking noise. This sounds like approximately 6 metalic taps in 1 to 2 seconds. It only occurs after a hot water tap has been shut off, when the pump overun completes (30 seconds)...

    Worktop vent

    Interesting. The manual on the fridge (and others) all state that for best efficiency when fitted beneath a worktop a vent should be installed. I'm going to fit a small vent anyway as I cannot see that it will do any harm and can only help in improving the efficiency of the heat exchanger...

    Worktop vent

    The worktop does not at present have the fridge beneath it. My intention is to put the fridge beneath it and add cupboards to each side thus reduce natural ventilation. Having considered what has been said I think I'll use my jigsaw and be careful!!!! Thanks Ian

    Worktop vent

    3" clear is ok. The worktop is laminated. Ian

    Worktop vent

    Hi, I need to fit a vent to the rear of a fitted worktop (worktop already installed). I've not used a router before and do not want to damage the worktop, so any advice would be useful! Thanks Ian

    Bedroom wardrobe and skirting board

    Hi, I'm fitting some new wardrobes in the bedroom. As I do not want them to stand away from the wall (by the skirting depth) I wondered if there is a replacement 'thin' skirting? Ideally I would remove the old skirting, fit new, then fit new carpet (without grippers in the wardobe area). Is this...

    Vaillant Ecotec pro 24 high return temperature

    OK, With the boiler set at 12 Kw it was taking about 3/4 hour to reach the 70 set boiler temperature. I increased to 14 Kw and it heats up quicker and still does not short cycle, the lounge remains at a stable temperature with no overshoot. I could reduce back to 12Kw and start the heating...

    Vaillant Ecotec pro 24 high return temperature

    Quite happy to play with this as I don't see why I should pay for an ineficient system if a little time may save a few pounds (anyway its fun to learn how things operate). I might try reducing the rating to 10 Kw (or less) when it gets a bit warmer (its -8 outside at the moment) and the...

    Vaillant Ecotec pro 24 high return temperature

    Well seems to be sorted to my satisfaction now (probably as good as it gets). Flow temperature set to 70 degrees, d1 at 8 minutes, d0 at 12 Kw, bypass fully screwed down and all radiators about 10 degrees drop (+-2). Despite the present freezing weather the system warms up well with no overshoot...

    Vaillant Ecotec pro 24 high return temperature

    I've got it set at 70 degrees and seems to be ok, d.1 set to 8 minutes. All radiators (trv's open) set to about 10 degree drop. I have considered outside temperature monitor but I do'nt have a North facing wall (house is a semi joined on the North side). It seems like when the house is up...

    Vaillant Ecotec pro 24 high return temperature

    The system is pre 1997 with 8 mm microbore but new Vaillant ecotec pro 24 (was rigorously powerflushed). It does seem that I cannot do better than 8 degree flow/return drop at the boiler because of the effect of the bypass. The minimum 10 degree furthest radiator drop happens because of the...

    Vaillant Ecotec pro 24 high return temperature

    Thanks ajrob. The best I can get is about 10 degrees accross the furthest radiators and so have gone for that all round. Still have 8 degrees flow return difference and the boiler set at 12 Kw at present. I'm going to let it all cool down now, reset the trv's and then see what happens! If heat...

    Vaillant Ecotec pro 24 high return temperature

    Thanks for the replies. I've set the bypass to maximum and adjusted all radiators for 10-12 dedgrees drop (approximately the radiator total output). This has increased the differential to 8 degrees. I've also just reduced the boiler output to 14 Kw and the flow temp to 70 degrees. Now I need to...

    Vaillant Ecotec pro 24 high return temperature

    Hi, My new boiler seems to work well but I have noticed that the flow/return values reported by d40 and d41 are only 6 degrees different (76 and 70) after the system has reached operating temperature. However, the whole system has been carefully balanced (15 to 20 deg. across each radiator with...
