Mr Venty Eco2 Wall model.

patman99

Have been toying with the idea of having an Envirovent 'Mr Venty ECO2 wall' fitted. However, the makers only mention the running costs with the in-built heater disabled.
Just wondering if anyone has one fitted and would like to say how much they cost to run when left to their own devices with the heater enabled.

Also, do they really reduce the condensation to the point that black mould can be cleaned-off the walls never to return?.

we had a quote for that exact unit last month, came in at £1250. We ended up with a Nuaire Drimaster 365 that does the same job. Fitted for £900. Its being fitted in a couple of weeks.
Most seem to go for the most basic units as many people don't need the summer cooling but for us it was pretty important.

We had a Mr Venty put in last winter. We went for the summer cooling model which means it has an additional vent through the roof. Can't say it made the house feel any cooler but then it wasn't a really hot summer.

It absolutely did eliminate condensation. Practically overnight. The mould we used to get in the bathroom, creeping up external walls has just not come back. Corners that used to be damp are now dry. Since that was the aim I am totally delighted with it.

I guess there was some impact on the electrical bill but nothing I've noticed. Our debits haven't been altered. But we do use a lot of leccy anyway.

You can feel it working. There is a steady but gentle draught coming down the stairs. That niggles my wife sometimes but either you have fresh air in the house or you don't. It isn't freezing but it's not warm air either.

Wasn't last year the warmest on record?

I live in a flat, so would be looking at the wall unit rather than the loft unit.
Have noted the price, so may be shopping around.

Glad to hear that it does actually work in eliminating the damp. Our bedroom is unheated, so gets loads of black mould.

Hi there,

Can't speak with loads of experience as ours was fitted at the start of January but we've had a month or so. It's fitted in the airing cupboard with the grille coming out above the door, aimed up towards the ceiling. It was originally set on medium (all to do with number of rooms & occupancy) but we've since had it turned to high. After that we had the 15 deg heater enabled as the air made our not very well heated house feel even cooler. It's not a gale tearing through but you know it's pushing air around. The unit has the heater in it anyway which can heat up incoming air to 10deg but it can be turned up to heat sub 15deg air which comes out of the grille more like 14deg

As a bit of background we have a sub 70 sq metre house & we have been running 3 decent dehumidifiers (ebac) for the last 5 or 6 years. They used about 1kwh in total when running so the heater enabled part is small fry in comparison.

We have high ish ceilings in some of the rooms & heating (all electric) is difficult as it never gets above 18 deg, even with the heaters on all the time, but here are the temps & humidity as of 11pm ish:

Living room = 14 deg & 64% rH
Dining room = 14.4 deg & 51% rH

Dining room is at the bottom of the stairs, so naturally better rH here. The living room is round a corner & doesn't get as low as we'd like rH wise but not bad given the current temps.

Energy wise fridge/freezer on, tv & sky box, router & a couple of lights along with Mr Venty with heater enabled & we were using 0.55kwh. It just dropped to 0.19 but as you may know the heater doesn't stay on all the time.

If you decide to go for one just have it installed as a normal setup & see how you fair. I'm sure the installer would come back to enable the heater if you needed it.

Sorry for rambling but I would have liked to have known more before we shelled out for this!

Any other questions just let me know,

is there anything in particular that you are not happy about.
ours is a largish house , difficult to heat and suffer alot from mould and condensation during wintier.
i am thinking of having a ceiling one fitted going thru loft space in upper hallway.
would you recommed having one of these units fitted.
thanks

rabialiones

just bumping thread as getting colder and condensation problems will start soon

patman99

Don't remind me. I need to urgently sort out the pending nightmare of cold winters and condensation. However, being on only a 12-week contract with no idea of whether or not there will be any kind of extension, I am having to think hard about how to finance an installation of an EcoVent or similar system.

Condensation was an issue with houses at least 50 years ago, but people learnt to live with it. Today people are more informed and also more demanding. Condensation is partly a lifestyle choice, so to an extent one chooses whether to have it.

With this post the bedroom is unheated and condensation is the result - a blindingly obvious situation and a blindingly obvious result. A solution would be to introduce heating and to introduce ventilation. Both could be done for very little cost. For example, a portable oil filled radiator can be purchased for around £25 - far less than the cost of a "Mr Fco Venty 2". An even cheaper solution is to control water vapour dispersion, use extract fans, open windows and use the trickle vents.
