Still getting condensation three weeks after PIV installed

 the condensation this morning on all the upstairs windows was massively reduced from yesterday morning,

Same here , it just wasn't as cold last night & we've no ventilation just circulation.

Ventilation is managed by opening the lounge window once a day for 10 mins whilst also opening the loft window.in our 1870's terraced  We've tried dehumidifiers but with little effect on condensation while at the same time making the air uncomfortably dry.

As the OP's experience with PIV is less than encouraging it's clear that reducing condensation is not as easy as a one solution for all.

, and for around £425 installed (I got a good discount on the unit), I thought it was worth a punt, but I realise not everyone is fortunate enough to be in this situation.

What make is PIV, is it heated version, who installed it ?

Nuaire Drimaster Eco LC, not heated as by all accounts the heating doesn't do much. Installed by a local electrician who came and quoted for it.

Out of interest, how much did they charge to fit it as considering the same?

It was £220 (he also swapped a transformer to a downlight elsewhere in the house in that cost) - but we already have lighting and power in the loft, if you don't have that it would obviously be more. He tapped the supply for the PIV off the lighting circuit as it was closer.

PIV systems are a very crude, and highly wasteful solution. Pumping cold air into your house and forcing out the warm air which you heated at great expense is, in my opinion, a very bad idea because you then have to pay to heat that cold air again.

Increasing temperatures to combat condensation is, again, a bad idea for basically the same reason. The real issue is that there is too much moisture circulating in the house.

You'd be far better simply running a dehumidifier because you at least get to keep the energy consumed as heat within the house.

The ultimate solution is to be far more thorough in excluding moisture from the living areas. More permanent (but probably too expensive to make sense) would be to get better windows or install a whole house ventilation system with heat recovery. However, by far, the simple answer is to mop up the condensation and learn to live with it.

" The unit comes with a 5 year warranty: 1 year parts and labour, remaining 4 years parts only"

Do you have same guarantee. I have read remaining 4 years parts only applies if use a approved installer.
