I'm trying to design the layout for bathroom fans and Manrose kit seems to come up a lot cheaper than brands such as Xpelair. Sometimes a quarter of the price, although I am finding it difficult to comapre like with like.
Anyway, is Manrose a reliable brand?
TIA

No experience of reliability, but their spares back up is excellent - really excellent.
There were two Manrose extractor fans in this house when I moved in. One was burned out, and the other burned out within a year (at which point they were 10 years old). Also, the little run-on circuit boards ran with a large resistor hot enough that it had burned its rating off and scorched the circuit board, which is not something I was particularly enthusiastic about having powered on continuously, particularly next to a 4" hole into the loft which would be ideal for fire spreading.
I replaced them with Deta (no longer exists). One did seize, but Deta include a self-reset thermal trip, so it didn't burn out, and I could repair it. They are both now 10 years old, and still working. I also fitted a vent-axia in another house 10 years ago, and that's still working, but it's a compact model and consequently slightly more noisy.
Vent-axia and Xpelair seem to be regarded as the better makes in this area, but are usually more expensive. My sample size of two Manrose fans bought over 20 years ago could well not be representitive of what you buy today, and that could be said of any past experience of any make.
Ta - sounds like you get what you pay for.
The Manrose I installed in our toilet goes round and round, but that's about all. Not a patch on the original Aidelle Loovent, which packed up after 25 years
I have fitted thousands of Manrose fans. Some years ago there certainly was a problem with them. This no longer seems to be a problem.
I use Greenwood Airvac for the better customers.
I bought and installed a Manrose fan about five or six years ago. I bought it because it was readily available and cheap. It works: it blows air through the outside vent but without buying an Xpelair and fitting that, I don't know whether the Xpelair would move more air, so I cannot compare.
The Manrose fan I bought had some problem with the timer. I cannot remember exactly what now, I think it would not stay on for very long. Manrose sent me a new PCB, so as another reply said, they seem quite helpful with spares.
Like Andrew, I found that underneath the PCB, the plastic housing had discoloured due to heat from the resistor. I can't remember whether the resistor on the original board failed causing this, or whether it was just a gradual thing from constant heat.
I hadn't seen inside any other timer fans, so I thought they were all the same. If there are better desigsn, perhaps I should consider them. If that resistor is powered constantly, not only is it a source of heat but it is another "standby" current to add to the electricity bill.
At the very least they should uprate the wattage of the resistor I'd say. Brian
It is powered continuously. It's part of the power supply for the run-on timer board. It should in theory be possible to design a run-on timer which powers itself off when the timer expires, but these don't. AFAICR, the circuit board in the Vent-Axia one is all tiny surface-mount components, so it can't have anything giving off as much heat, but I haven't investigated the logic it uses.
That will help the resistor, but will not stop damage to surrounding components, PCB, etc.
