Humidity, no heating and drying washing

[OnTheRanDan]

My house is really high humidity now and I'm worried that it'll only get worse over the winter if I'm not putting the heating on very much due to the prices.
I have a couple of dehumidifiers which are good and also provide a bit of heat but is it better to buy and use a tumble drier?
Or would it be better to just put the heating on enough to dry washing and keep humidity at bay?
What would be the cheapest and most effective option?
How the heck will people dry their washing?

buy a spin dryer as they spin at 2800rpm and will get significantly more wet out of the clothes than the washer will. It is an extra job though. Then line dry if at all possible and finish inside.
if you have a greenhouse you can stand clothes horses in the green house and the washing will dry without adding moisture to the house.
