Airlock in the morning All aspects of plumbing questions and answers, help, tips and information

[Claydoncamper]

My hot water is heated by an immersion during the night on economy 7. Before I can run my hot taps in the morning, I have to run the power shower which expels air (noisily) and then and only then will my hot taps work. If the heater is switched off for the night, there is no airlock the next day. Obviously something is happening somewhere as the water is heated but could someone tell me how I might fix this really annoying problem please.
Many thanks in advance.

this is a bit odd - gravity or mains pressure? do you have feeder tanks in the loft?

just one thought, having re-read your post. you say you have to run the power shower to get the taps working - assuming that your power shower runs off a pump? ergo gravity system.

check that it's properly plumbed, ie that it has dedicated feeds from the hot water tank and cold water tank. it could be that the apparent cure for your problem is actually also the cause - the pump could be sucking in air via the vent pipe.

only feasible explanation without looking at it. might be you need to get someone in to inspect.
