Hi guys and gals.

I own a smallish bungalow which I rent that due to its construction has some damp problems - its a 1920s build with little to none ventilation.

So - the company who manages it have supplied me with a quote to install a couple of fans (bathroom and kitchen) and a PPU/PIV unit.

The cost for this is (supply and fit)

£1283 for the piv
£425 for both fans.

I realises everyone wants to make money - but does this cost seem fair/right to you guys?

Really depends on what they are fitting, but:

The usual PIV unit is the Nuaire Drimaster, price approx. £300-£350. That leaves about £900 for labour.
A standard extractor around £50, assuming you don't want the cheapest tat, or the overpriced designer pieces. That leaves about £300 for labour.

All 3 could easily be installed in a day by one person, so that's £1200+ for a days work.
 
Haven’t got a clue what a PIV is but extractor fans are easy to replace if already there but I think there is a lot more involved if fitting one from new - drilling the hole in the wall, supply and fit an outside grill, getting an electrical feed to them which, I assume, must be done and certificated by a qualified electrician.....

They don’t look too complicated to fit either.


A friend of ours rents out a couple of flats and the biggest problem she always encounters with renters is mould. She reckons they just dont bother opening the windows to let some fresh air in.
 
Well the PIV unit is going to supply a positive airflow into the property, but I suspect you need trickle vents to allow the air out afterwards - although the fans may well let the air out. Fitting the bathroom and kitchen fans will need a core drill, and an electrician to fit them, but £425's a bit high, so call a couple of electricians for comparative quotes. Now, what sort of fans did they specify, as a humidistat fan would be best in the bathroom, and this will pull out a lot of moisture from the bathroom, and air from the rest of the property. As this might well run for long periods, it might be better to think about a heat recovery unit in the bathroom, and a fan in the kitchen, and ignore the PIV unit instead.

I'd suggest you keep looking.
 
Hi Chaps, cheers for the feedback -

Yeah - installing the Piv unit looks pretty simple. Just a case of getting a qualified electrician to wire it.

In fact thats probably what Ill do - buy it, install it will save me close to a grand.

The bathroom and kitchen fans Ill think about. Maybe myself, maybe someone local.
 
Well done for deciding to have a go at the PIV unit yourself, but as the bathroom is the worst place for generating condensation (hence going for a humidistat fan), you'd be best to go for that one, and the electrician should be able to tackle that as well. The kitchen is the last one on the list, as cooking and boiling the kettle also generate condensation, and you might get a good deal with all three being done at once.

Forget seperate extractor fans, one such product was this

Vent axia no longer make it unfortunately, they were rather good.

This is the kind of thing you want

These units do both extract and ventilate but reduce heat loss. I think it's a bit bonkers what they've suggested !!!!! Positive ventilation and two extractor fans x 3 things to go wrong verses one ....no contest.

Have you seen the costs of MHRV compared to PIV?!

Yes I've supplied and fitted them, I haven't bought one recently. It depends where you shop obviously but I get trade prices.
 
That's unit only, I thought the insulated pipework cost quite a bit?

And that now the units should be installed outside of the loft... that one looks quite loft-y!

A PIV is a much cheaper solution for a rental property. MHRV is a far superior system, but a completely different cost to match.
