Overly humid bungalow

Reveuse90

Since moving into my bungalow a few years ago I've noticed it can be prone to damp and consequently sometimes mould.

I purchased a dehumidifier and have had new windows put in with trickle vents.

The bungalow is 1960s, concrete floors and we still have the warm air heating system. 

A few months ago I bought humidity monitor

We also have a bungalow with the warm air heating system. Although most of the floors are timber suspended. Windows are all pretty old. Before we bought dehumidifier, the humidity monitor would hover around 70%+. There was condensation on windows that would turn mouldy. We didn't particularly open windows often due to trying to conserve heat.

Now we use dehumidifier at every opportunity. The only problem is that it is electricity hungry (we bought a desiccant dehumidifier) so we run it most nights because of cheaper electricity tariff, and also during bright days from solar energy. It really helps, the humidity rarely raises above 50%, and no more condensation on the windows.

I would persevere with dehumidifier, but also investigate just in case if you have a damp problem other than general living/breathing/cooking humidity.

Have you established whether it is condensation or damp?
