Alde heating dripping noise (1 Viewer)

[Ashwells]

We are getting a dripping noise from the the header tank which is located in our bedroom drives us nuts in the middle of night is this normal? , my only solution is to turn off the system not so good on those cold mornings .

Doesn't sound normal to me. Anyone any ideas??

If it is the pressure cap of feed and return hoses the water would run down the pipes and be silent.
If its the pressure cap allowing water into the outlet tube it may well be that.
The pressure blow off pipe on mine is tucked down the pladtic pipe trim panel...by about 6" and could/will drip on the wardrobe floor.
If yours is also short and open try slipping the end in a small plastic bottle and see if any water has collected next morning.

Only other thing i can think is a faili g pump bearing allowing the impellor to intermittantly contact the impellor housing.
A new genuine pump assembly is around £110

Ours makes the same drip, drip, drip sound when the heating is on and the pump is going.
Fortunately our little header tank is down near the front of the van so we don't hear it during the night.
I just presumed it was normal as its the first Alde system we've had in a motorhome but come to think of it we didn't get that noise when we had it fitted to a caravan a few years back.

When our van was new there was a noise like a dripping tap (or ticking) and it drove me potty tracing it to being an aluminium pipe that was touching the body frame. As it warmed and cooled, the heat changed caused it to move very slightly against the frame causing the noise.
Worth a look.
I cured it by putting a piece of sponge between the pipe and body, never heard it again.

The most likely cause of the noise is gurgling in the header tank and not fluid dripping. Check the liquid in the header tank is between the min and max marks when it is running. If it is it won' t be dripping out of the overflow pipe. Check there isn't air in the system. There are bleed valves on the radiators (not while pump is running). If air bleeds out make sure to top up the header tank with 50/50 mix of antifreeze and water. Take the cap off the header tank. Is there a pump attached. If there is no pump then the pump is attached to the boiler. A boiler pump can be adjusted for speed. Normally speed 2 is set. If it is set to 4 or 5 reduce it to 2 which should cure noise.

Alternatively ring Alde who are extremely helpful with advice.

thanks for your advice will take a look at the pump settings and try to bleed the radiators

Couldn't have put it better ourselves, we had similar issues in the first caravan that we'd owned with Alde heating & it was driving me potty til we took the bull by the horns.

This problem is not uncommon with Alde systems and new users often complain of similar noises. We have suffered it on a caravan and mh in the past and with a tank near the bed it was a nightmare literally. At least it is not a serious or expensive problem.

Had exactly the same issue and was def cured by turning down pump speed on side of boiler unit to about level 2
