Heat pump dryer in cupboard.

Mr_Singleton

Looking to replace my vented tumble dryer and move it into the airing cupboard which also includes the boiler, mains gas & water stopcock and consumer panel.

Decided to go for this model (sorry for the long URL but MSE won’t allow !!!!!!!!

Right, will have the cupboard doors open when in use but the nearest window is in the next room. Is it likely to get enough fresh air to function properly. Will it effect the boiler etc as I assume it will give off some moisture during use? Can I bodge plumb it into the boiler over flow funnel or will the water coming out be too much for it to handle?

Anything else I need to think about?

Thanks.

We have a self condensing tumble drier under our boxed in staircase. The meter/electrics are in the same cupboard.
Not had any issues in the couple of years it's been like that, all we do is, as you say, leave the door open when it's on.
Ours gets the water emptied manually.

It shouldn't give off any moisture when in use, its all caught in it's own container that is manually emptied, it doesn't get plumbed in.


It will be fine as long as you keep the door slightly open and make sure there is clear space round it to draw in air.

Thanks both.... I knew that they could be put in confined spaces it was the boiler and electrics that concerned me.

I have that model. It doesn't give off any moisture. Ours is plumbed in but there is a cartridge system in the top which you can use for the water collection if you prefer.

Don't buy the pod flacon things, they dry up and the smell is very unnatural. If you haven't used an heat pump dryer before it WILL take a lot of getting used to.

It takes much longer for things to dry - don't think of the electricity as it's using much less than a conventional dryer and it is using the residual heat to help recirculate back into the drying cycle. The most annoying thing for me is the noise. It isn't as quiet as a conventional dryer, but that's an heat pump system issue rather than Miele.

It has both options, you can plumb it in or you can use the cartridge drawer in the top to empt collect the water.

That's handy, in that case then yes it could be teed into the boilers 15mm blow off valve if it conveniently placed to do so.

After making sure that doing so doesn't breach any gas or safety regulations.
There are strict requirements for boiler installations and it's possible that having water draining into the same pipework as the valve output may not be allowed.

I'd say that the over-pressure vent pipe is NOT suitable for condensate from a tumble dryer. That usually goes outside to a visible 'overflow' pipe that gives warning that 'something is wrong' and is not usually designed for a significant and regular drainage of water!

However the boiler condensate drain pipework might be suitable, for use if a washing machine u-bend can be added to it (assuming it connects into the main sewerage pipework). OP may need to seek advice of a plumber (or post pics of the existing pipe works for forum experts' comments)?

I'd be concerned that this dryer location may impede emergency access to the consumer unit, stopcock and gas valves... Condenser dryers are extremely heavy and difficult to move! (62 kg in this case). Last thing you want if trying to isolate the stopcock in a hurry is to have a heavy tumble dryer in the way!

Read the specs on condenser efficiency.

All condenser dryers don't condense all the water they extract from the clothes.

The best A rated are around 90%+ efficiency, 10% goes to the atmosphere.
B rated nearer double that.


That one linked is 95% but seriously expensive when there are £400 ish models nearly as good with decent warranty.
