gas heating not working downstairs
Hi,
I have a gas heated 2 story house. The boiler works by electronic timer that divides the house into an upstairs and downstairs with a button for each. All was working well but now only the upstairs heating is working. When i hit the boost button for upstairs the boiler kicks in (ie the flame comes on and it starts making some noise as always). Newbie...sorry. If i then stop the boost button for upstairs and let the boiler stop...then hit the boost button for downstairs the boiler doesnt kick in. The electronic timer looks fine as in the light comes on etc.. NB There is pressure in the pressure reader on the boiler as obviously upstairs works fine. Thanks... |

Your system is most likely separated with 2 two port valves, the one which regulates the downstairs might have stuck. On the 2 port valve there is a little lever on the side, try pushing this to manual position and see if it works.The heating won't cut off though if it is left in the manual position. http://www.ridgeonsukstoreonline.com...H1800067_m.jpg |

In case this is of any use...the gas system boiler is a Vokera Mynute
16e...i.e. this is a large white box which has the pressure guage on it. Would the regulator be inside the box...theres a panel you can screw off. I cant seem to see anything else around the box/boiler that would do anything. Thanks... |

gas heating not working downstairs
Hi,
After more examination, I found the plumping valve for downstairs (myson power extra mpe222). I found the manual override switch on the side and when i moved this to the manual position...then the downstairs radiators stated to heat up. Does this mean that the myson unit just needs to be replaced...or can it be an indication of some other problem. How long do these units usually last...the house is about 4 years old. Thanks... |

Do you have the necessary knowledge and equipment to check whether power is getting to the valve? If you can confirm that it's getting power when it should, then I believe the actuator can be removed without disturbing the wet side at all, and you can then either have a go at repairing it or replace it. Google "myson mpe222 actuator" and you'll find a supplier. It may use even use a common type of synchronous motor as sold, for instance, by Screwfix. -- Kevin Poole ****Use current date to reply (e.g. )**** |

The way these things work is that the timer and room stat open the valve and, once the valve is open, auxilliary contacts in the valve actuator close and tell the boiler to fire. For some reason your valve isn't opening when it should. There are lots of possible causes for this, and some investigation is required in order to find the actual cause. The most likely causes are a failed motor in the actuator or the 'wet' part of the valve partially seizing - making it too stiff for the (not very powerful) actualtor motor to move. Other possible causes are a failed room stat or a discontinuity in the wiring between timer/stat/valve. When you operated the over-ride, did the downstairs radiators get warm *without* the upsdtairs ones being on, or only when they were on? -- Cheers, Roger ______ Email address maintained for newsgroup use only, and not regularly monitored..

Sorry for making you discover the valves yourself.... I went to sleep. |

They are often placed in airing cupboards, or perhaps in the loft space. How is your hot water heated? If that is also heated by the boiler then there will probably be a zone valve controlling that as well. -- Cheers, John. /================================================== ===============\ | Internode Ltd - http://www.internode.co.uk | |-----------------------------------------------------------------| | John Rumm - john(at)internode(dot)co(dot)uk | \================================================= ================/ |
