Well, it is pretty rude, but also pretty typical.

Are you saying the temperature of the exhaust gas from a gas boiler isn't hot? At least that incorrect view is consistent with many of your misconceptions - e.g. that the Nibe doesn't have heat exchangers(!), and your inability to know the difference between energy and power and your random use of incorrect units of both.

I notice you previously posted some months ago about an expert engineering report on the system, and when one of the conclusions didn't meet with your views, the expert became 'a so called 'expert'' whenever you referred to him or her! So your abuse of professional engineers, and probably all other professionals I expect, seems widespread, even when they initially set out to help with peoples' difficulties with these systems. I note this saga started about 18 months ago (and I have occasionally posted on this thread from about that time) - ever wondered why you don't seem to be making much progress in finding a solution?



Nonsense. If you commission an professional engineers report, there's nothing Nibe can do to stop you publishing it, however critical it may be. Note I say 'a professional engineers report' which will be factual and not libelous, whereas if for example you wrote a report, I expect it would be libelous and Nibe would have the right to stop its publication. Anyhow, you previously said there were many reports - yet you can't or won't produce even one of them.

There are many other misconceptions I (and incidentally any other professional engineer) could pick up on, but I'll leave it there, and wish you luck with solving your problem.

Sorry if we offended...please do try to get both the independent reports ...they are with BPHA their number is 0330 100 0272...the person is head of property services.....if you can get the reports I will give you £300 for each .......

Yep yawn...... libellous....sounds familiar... don't suppose you work for NIBE.....they have tried and failed ....shouting the odds in the face of the DECC and EST is funny ...we have offered for you to visit our locations ad discuss your opinion ,,,we will even pay for your time....we are the uneducated only reporting on what engineers have decided.....not us....no reports have been written by us,...we are the poor sods paying a high monthly bill...please do discuss instead of shouting....

I was given a copy of the NIBE exhaust air heat pump catalogue and guide in March - no warnings in there that it is only suitable for use as a supplementary method of recovering heat produced by an efficient primary source.

Hi,

I moved into a my new 2 bedroom apartment on the 2nd April, since moving in we have already used 700kwph. Our Nibe is currently set to 24hr water heating? The engineer told us to use this setting? But im wondering whether this is right? Looking elsewhere were using double what we expect to be using in electricity.

Unfortunatly, 19Kw / day is the best your going to get.

Having 24 hour hot water isn't right, as the boiler's heat pump should provide you enough water this time of year.

Make sure it's in Autumn/spring mode.

And, make sure your extra hot water is off. If you have the 360P, it's the button with the tap symbol, keep pressing it until it says OFF. Hopefully, it should drop from 23Kw to 18-19Kw.

You can make a further saving by turning the central heating off (Summer mode), but only if you're confident the house can stay above 17C. I don't think it's warm enough weather yet...

But most other forms of heating do.

Certainly, if they ripped out the HP and replaced it with a gas boiler, a thermometer on the exhaust would show quite a high temperature. Ditto a stove, open fire, oil boiler. So that video in itself doesn't prove much (although I found it very surprising) since many other efficient heating systems exhibit the same effect. As I said before, if it is like that all the time, then something is wrong, but it's possible that there may be an operating regime where a warm exhaust is expected for a certain amount of time. (I'm not saying there is, but without knowing in detail the design of the HP, no one can say there isn't - that's why I said I'd like to see Nibe's comment on the video). Do Nibe reps ever write on this forum?

I think the key to finding out what's going on with these things is one of the technical reports which I hope I can get my hands on.

A modern and efficient gas condensing boiler exhausts almost cold air.

And, no other boiler pumps gallons of unrecovered indoor air outside.

The video proves a lot.

Thanks for the response. Since my post ive had a play myself, actually turns out it was using more than 23, more like 30.

I turned off the hot water.

I also turned off the fan aswel, but am I right thinking that stopping it from working completely?

Im also not sure what setting the dial on the boiler should be, its currenty set to -2 but I have no idea what that relates to. The engineer told the missus to leave it on winter setting with 24hour water, he clearly didn't have a clue!

Fans need to be on, otherwise the heat pump won't function.

Move the dial upwards bit by bit, every couple of hours, and the temperature of your radiators will increase. When your room is warm enough, it's just a case of turning dial a notch up or down when it's getting too warm or cold.

We had the same, an engineer came round to reset the thing and when they finished, they left it with the hot water boost on. That was an expensive day.

So if the heat pump isn't functioning then we shouldn't get any heat in the radiators. I left the fan off this morning, increased the heat curve and increased the thermostat to see what would happen. The flat was warm by the time the missus woke up and said the radiators were all definitely on.

So what would have been making them warm if the heat pumps not working?

We were told when were moving in that we would be shown how to use the boiler by an engineer who would make sure we had it setup correctly, I was at work that day so missed the chance to question him on the functions. The missus has baby brain so doesn't remember half of what he said!

Not sure what to say mate, there's supposed to be a constant supply of air for the heat pump to do its thing. I just hope your immersion isn't kicking in to compensate.

Will check how much electric we've used today when I get back and report back!
