    Default Noisy been heat pump water heater



    Just wondering is anyone has any ideas on this one.

    I have a 325 rheem heat pump heater, the recall has been done however the unit constantly vibrates and is so loud it can be heard inside the house when it's running.

    If I apply slight pressure on the fan assembly the vibration stops. Could this be due to the recall not being carried out correctly?

    Has someone had a similar problem?

    I would suggest you have it inspected ASAP because the fan unit shouldnt vibrate like that.
    Either its out of balance or not properly secured, either of which could result in the units failure.
    I stand unequivicably behind everything I say , I just dont ever remember saying it !!

    ...or try to get a refund and buy a Stiebel.
    Most of the well-known brand heat pumps are... let's say.... not good.

    If these are like many appliances sold in Australia today, its where it was unloaded out of the container from China where it was made and had a 'brand' name applied along with the usual spurious claims that it is the 'Best'.

    I have one of these Rheem Heatpump HWH. Ours was making the same noise this was before the recall. The vibration eventually damaged the copper pipe which holds the refrigerant gas. The pipe began to leak. It was fixed under warranty. I sugest contact Rheem soon rather than later. The heater still has the top element which gave us hot water untill the heater had its service. I am happy with the heater now but I did think I had purchased the wrong heater.

    Having an electric element sort of defeats the 'GREEN' purpose of those units along with having an electricaly powered pump to make them work.

    No need to bring logical thinking into it. Same can be said for electric cars where you are just moving the problem from the car and actually polluting more due to the electricity generation.

    Back on topic, if its vibrating then there is a problem and i would get it fixed asap. No need to do more damage by letting the problem go.

    As far as the noise, well heat pumps are not a quiet unit. Ive have worked for customers that have them and from inside the bathroom where i was working you could hear it running on the opposite end of the house. I had to go out side and check out the noise and sure enough it was the heat pump and it sounded like a wall mounted air conditioner.

    Quantum heat pumps do not have an element of any sort, and the electric compressor uses less power than the element in the panel type solar systems.
    Ours has been very efficient compared to gas or electric.

    On the O.P.s question, if the vibration stops when you put pressure on the fan unit, it needs balancing. If it is still under warranty, get them back to fix it.

    You're on the money ptrott!

    I had the techs out yesterday and the problem was that the compressor unit which sits in front of the main heater was not supported by a base and was just hanging off the unit in the air.

    The compressor was falling forward and pulling some other parts with it.

    We used one of the fly by night mobs to buy the heater from when the government was handing out big rebates, and they did a half arsed install.

    If anyone else bought one of these systems under the same scheme, it would be worth checking the footings around the compressor.

    Good news is, that now it's stabilised the noise has gone and cost us nothing to fix.

    just out of interest , are the heat pump HWHs saving you any noticeable amounts of money?
    i was unsure so i bought and mothballed a conventional tank before the plumber's co-op stopped stocking them.
