Dear members,

I am looking into a new heat pump dryer (Miele) - we currently have a Miele T8822C Condenser dryer, and why we can't fault the machine at all, our electric bill is going through the roof. We are a family of five plus a yorkshire dog.

I guess my question is is there a significant difference between the electrical consumption of the regular condenser vs the heat pump dryer.

Your inputs are much appreciated.

Regards.

I have a Bosch A+++ dryer. I have yet to dry a load that consumes more than 1 kWh after a (just) 1200 rpm spin. Power draw is about 1/4 of my previous air condenser dryer.

Usage by runtime

 Best way to break that down is by runtime.

On average, including heater off times, a normal vented or condenser dryer uses about 2kW.

A good A+++ dryer pulls about 0.6kw.

In my calculations, with my electricity cost, it takes about 1000h of operation to save the difference between a B-class dryer and an A+++ dryer.



With current quality dryers, dry times are not much longer with heat pump models.

Just make sure you check the runtime for full loads.
All models needing less than 3h are reasonably quick.

My Miele is rated at 156min for an 8kg load and about 100min for a half load.
Even the heaviest loads are done in under 2h.


The next big savings might be old cooling appliances, hot water/heating if electrical or even just electrical malfunctions.
Switch off everything that you can reasonably switch off, then watch your electric meter as you switch stuff on one by one.

Also, running appliances only when they are full and taking the time to actually fill them all the way.
In my old flatshare we were 6 people and we only ran the DW once a day due to proper loading compared to the up to 3 times if everyone just threw their stuff in however.

Fastest cheapest way to buy dry clothing in a dryer

For any home serve by natural gas a gas vented dryer is by far the best choice, next best choice would be a heat pump dryer for cost of operation but it may be slow to operate.

Vented electric dryer is about 25% cheaper to run the condenser electric dryer, in fact a condenser electric dryers the most expensive way and most energy intensive way to dry clothing.

What are electric rates in South Africa?

thank you all

 For your positive inputs, I will reply as follows:

@ Logixx - Our Miele runs at about 2 500 Watt - but I suppose that it will gear down as the temperature is reached - I wil lhave to monitor it more closely to see the actual electrical consumption;

@ henene4 - Like stated above I will have to investigate the actual consumption more closely - but from "guesstimates" I would suggest at the very least about 3kilowatt hour per load:

@ Combo52 - There is no natural gas in South Africa, only propane and it is also rather expensive as the price is determined by the fuel price, so the moment oil price climb our propane prices climb;

@ Jerrod_Six - currently I pay 3.10 rand per kilowatt hour - it is very cheap if you convert it to Dollar or Euro, but we get paid in rand so very expensive at the moment and getting more every year.

Thanks so much for the replies - I will keep you posted on my decision.

Regards
