Question about Heating & Cooling

1 Answer

We have a FERROLI F30 combi boiler and our DHW runs hot and cold, the boiler is working ok. But when we turn on the hot water tap to run a bath, the water gets hot for a short time before running cold again, we then have to knock off the tap and run it again {normally by running the hot water tap in the wash hand basin until its hot before transfering then to running the bath tap} sometimes it works and other times it doesn't Please can you tell us whats wrong and how to fix it?

Hi! My hot water taps from the wash hand basin and mixer bath has low pressure. I`ve got a combi boiler in the first floor. Can I install a single impeller pump connected from the hot water outlet from the...


In a word no. Combi boilers work on balanced pressure.ie the mains cold supply to the boiler should be around 1 bar minimum which would give a hot water pressure of the same 1 bar. Assuming the cold water pressure is fine, it sounds like you have a restricted flow on the hot side. If you live in an area with water problems the hot water systems pipework calcify over time effectively reducing water flow. Unless any flexi hoses are kinked, check if there are any filters in the appliances that may be blocked.Also check all valves are fully open and if possible check if there are any restrictions at the valves. Failing all that and the taps are in good order it is possible to fit a pump before the boiler but this may only be a temporary fix overall.

No hot water coming from combi boiler ( vailliant)


I have a BAXI combi Instant 105 HE bolier. It has been very cold for the past week and the hot water is not working (though the heating is). I have cleared the overflow flu pipe of ice but this has not solved the problem. Any suggestions?

Combi worcester 240. Plenty of hot water when heating running bot only luke warm when heating off. The pin in diverter valve working fine and ive tested the switch and that is ok !! Anybody got any ideas....


what u need to do is let the flow and return pipes for the heating go cold they are normally the 22mm ones and if 1 gets warm when u run your hot tap then u need a new diverter valve. if they stay cold then u need to see if the boiler is igniting in hot water so turn off the heating and just run the hot tap to see if it ignites get back to me

Combi boiler no DHW


if the boiler fires when the tap is opened then the diverter valve is working ok it must be a blocked plate heat exchanger which is the stainless steel rectangular block inside the boiler connected to the pump and the mains cold water.
it will be blocked on the central heating part probably with black scale. it is possible to clean out but sometimes it is better to just change the plate. but remember to flush the system as well or the same thing will happen.
