I'm really not sure which units are the best, and what you should buy... But I hope that list is helpful.

I would analysis the noise, I bought a dMEV fan said it was super quite, but had to replace it. The one I bought next was 20 dBa quieter. Basically you have to take the cover off to see if it's running.

For our garden room dMEV I used Greenwood CV2GIP.

The more I look at the Greenwood CV2 range, the more I think we need one in our bathroom (we don't have anything at the moment and are about to do a bathroom renovation). Is it possible to vent these through the roof, into the loft, then out through the sofit/fascia? Or is through-the-wall preferred? I would look at the 24v option because bathroom....

I believe they can be ducted they have a 24v version also. I got mine from eBay for £55.

The thing I don't like about these reviews they are anonymous. Some of the test results show better performance on fan speed 2 than on fan speed 1, some the other way around. So some consistency of testing may not there.

 

So he's getting 60+ efficiency,mostly above that and at one 81% - data sheet for the mini states up to 84% efficiency.

I went with humidity controlled trickle vents in the end, ordered 5 of them today. I'll replace the ones the vents that come supplied with the windows (on the windows that I fitted them to, the upstairs bedrooms), and retrofit one to each window in the extension.

 

Whether I'll regret that decision, who knows.... But the only spot I could put a dMVHR unit would be facing the prevailing wind, and we’re in a hi wind speed area so was concerned by that aspect of the strategy.

"Yes the Ego is an ideal unit for heat recovery within a wet room. This unit is only really suitable for a wet room as it does have an automatic boost mode which can be loud (noise similar to an extract unit).

 

This would not be a suitable unit for habitable rooms such as bedrooms.

 

The E260 is the unit suitable for bedrooms, this unit works in pairs. As an example; with one unit in Bedroom 1 and the other unit in Bedroom 2 they alternate between supply and extract every 70 seconds. They use a centrally located controller.

 

The Ego is priced at €1,311.18 inc VAT.

(This price includes the Ego unit, duct pipe, controller, transformer, internal and external grills)

 

The E260 pair is priced at €2,063.94 inc VAT.

(This price includes 2 E260 units, 2 duct pipes, 1 controller, 1 transformer, and 2 internal and 2 external grills)."

 

"Oh I understand now. Unfortunately, we don’t have a heat recovery unit that would work on its own bar the NexxT unit. But the Nexxt is a large unit at 500mm x 500mm.

 

The Ego is more suitable for wet rooms.

 

There is a Silvento unit (also more suitable for wet room areas)… and would be extract only and not heat recovery."

 

Some relevance to this thread, so posted it here. This was a discussion I had over email with Partel this week.
