HRV in both bathroom and kitchen

[bludger]

I've just read something of the advantages of single room heat recovery ventilation units. The guy had used a largish Mitsubishi and the air was dried and warmed well before being returned to his lounge. He reckoned that it helped reduce his heating cost, too.

I'd like something similar in my two wet rooms. The bathroom is 2.44 x2.44 x 2.44 = 14.52 cu mtrs and the kitchen is 2.9 x 3.56 x 2.44 = 25.82 cu mtrs.

I don't want or need anything large. Vent Axia's HR25, for instance, only needs a 152mm hole drilled in an outside wall. and doesn't look much larger than an ordinary extractor fan. I'd value advice on the worth of HRV for individual rooms and, if possible, on the effectiveness of small units.

I understand that they may not be cheap but I don't want to waste money on carp!

I use one of these heat recovery units with a ducted ventilation system for my kitchen, diner, bedroom and en-suite. Click

Works well.

Your system seems a bit too complicated for my needs, Stoday. If I use individual, small units - one each to both the bathroom and the kitchen, it would avoid ducting.

The Vent Axia unit I mentioned just needs inserting through an outside wall and then all connections can be fitted from the inside. It sounds ideal - if they work well.

Thanks for your reply.

I've decided that an ordinary extractor fan with humidistat will suit my purposes well enough. The self-contained heat recovery units seem too new to have any reviews anywhere and I always like to read those before I buy.

Thanks to those who read this.

I had one in a former kitchen. As it brought in fresh warmed air in the same volume that it blew out stale air, it did not create any suction in the kitchen, so it did not prevent cooking smells from diffusing round the house like an extractor does. Nice quiet unit, though. Could be handy in a living room.

Thank you JohnD. That's the sort of information that I was after. If they don't take out cooking and bathroom smells, they aren't what I need.

I'm currently looking at the Airflow Quietair 100mm, 2speed + timer at tlc-direct's website. Seems a good unit: 9 watts, 2min delay start, adjustable timer from 6mins minimum and whisper quiet. Just the thing for the bathroom.

I'll figure out the kitchen later.
