SAVE MONEY ON HEATING

SUGGEST TURNING OFF RADIATORS IN ROOMS THAT ARE NOT IN USE,
BED ROOMS TO HOT, THEN ADJUST THE BALANCING VALVE THE OTHER END OF THE RADIATOR , REMOVE PLASTIC CAP, SCREW BRASS VALVE STEM TO OFF FULLY CLOCKWISE, THEN BACK OFF ABOUT THREE TURNS OR ENOUGH TO REDUCE THE FLOW ,SO THE RADIATOR IS NOT RED HOT BUT WARM, IF ANY RADIATOR IS COLD AT TOP IS'T A SIGN OF AIR IN RADIATOR. USE BLEED KEY OPEN SLOWLY ,AIR WILL COME OUT THEN WATER , CLOSE, CHECK COMBI BOILERS 1 BAR WATER PRESSURE.

Make : Weil-McLain Model : CG-5-SPDN Series 12 I have the above mentioned boiler which is located on the 1st level of a three story one family house, the area where the boiler is located is insulated.


You don't have an optimum distribution of steam in your house. Try closing a little bit the valves supplying the heaters in the lower floors. Close a little bit more until you get the desired balance.

hot water on inlet side of radiator very slow running. outlet side stays cold


If this is happening with only 1 radiator then you have sludge build up inside radiator. Allow system to cool and shut inlet/outlet valves. Drain water from RADIATOR side of valve. Remove radiator and power flush to remove sludge. If this is happening on several radiators then the pump could be failing. If this is a new system then most likely system needs balanced.

I can only get heating to the radiators upstairs, not downstairs


balance the rads.
upstair radiators turn all valves off,heat will then divert downstairs,open valves upstairs 4 turns on locksheilds and number 4 on trvs if u have any.
then if that does not work get a combi or powerflush.
if u cant afford then drain a little from rads,get x300 sludge remover from plumb shop and put in header tank(not hot water tank).
then fill system up and repeat balancing.

Central heating radiators downstairs take a long time to heat up


Problem is balancing & flow. Turn down the other rads until the inlet [flow] pipe is hot but the outlet [return] is luke warm. The rads have two valves - use the one which has a non-operation cap [just turns without doing anything]. when all the rads are the same temperature the system is said to be balanced and should be left like that using the other valves [with operating cap] to turn them on or off as required
