behind a door is the best place for a rad as it is a space that can't be used for furniture etc, i was sure the best place for a rad was under the window where possible mate like they are designed for (convections and all that)???

ok ill have a scan around tomorrow. thanks mate

i was thinkin that its just that i need the customer to pay and order it all so thought it would be easier for me to fill out a basket online then the customer could go online and purchase the things when they were ready. had problems with this property developer paying up on time so now agreed...

anyone know where the best place to buy a vaillant heat pack online is? qualified engineer just waiting for combustion chamber confirmation thanks.

i would predict that the heat exchanger is possibly scaled up and the humming noise comes from the pump as there is an undesired restriction. just fixed this problem at work today which seems very similar to your situation. try turning the pump speed down. does the noise go away? if so then i am...

can some one tell me how i can find my firewall to allow me to get torrents through it. tried port forwarding and still cant get it to work. the firewall i think was installed by the shop i got it repaired at which has now shut down. it was like their own special antivirus and firewall thing??

replace the valves even if you did manage to turn them down chances are they jhave been stuck in that position for so long that they will leak anyhow.

sounds like an overheating problem. somehow water is not being dispersed around the system as it was designed to. maybe draining it down shifted some sludge which has now caused a blockage??

you cannot have isolation valves on a vent pipe. fitting it on the return is fine. it is illegal on the vent pipe because where would the expansion of water travel whn the heating gets hot???

yes it discharges outside through the pipe the boiler insides will be fine if the blow-off pipe is installed correctly. should either run to waist height or turn into the wall to avoid scalding when discharging. you need to replace the pressure relief valve and next time when some1 says dont...

fit the magnaclean on the return pipe as close to the boiler as possible

you need to use a powerflush then possibly fit a magna clean afterwards. a magnaclean will only collect debris from water passing through it so wont really remove any stuck in the bottom of rads. fitting a magnaclean afterwards will help remove any leftovers and prevent this problem occuring in...

that isn't no good in the long run is it. customer would not foot the bill to have the system changed to 2 pipe what other option did we have spent 2 days doing the most precise balancing there is and still only getting luke-warm water. there was two options leave the radiator cold and rile...

yes it would be reasonably safe to assume your pipwork is capable of the extra expansion of water. i wouldnt fit a mini vessel as in my opinion the manufacturers are just covering their backs. if you had a shower there previously then you should be fine. yes the one in the boiler is for the...

when the shower is on it fires the boiler. the boiler pumps out hot water. water expands by 4% when heated so when you turn the shower off the expansion needs to be accomodated for as it could possibly burst a pipe. the mini expansion vessel allows it to do this until the water contracts again...
