whole house heat recovery systems

[jamie08]

Hi forum memebers.
Im researching the possibility of installing a heat recovery system in our 3 bed, cavity wall insulated, double glazed, gas ch, brick 80's build semi.

What are the views/opinions of the forum on such systems.
I understand the science and mechanics, however does any body have first hand experience of living with these systems?

Any pointers, info or advice greatly appreciated.

Thanks.

hi, I have installed several of these, and hey are as simple or complicated as you want.

Regardless of the level of complexity you go for, none of them are viable if your buildings air-tightness is not up to a high standard.

I would strongly urge you to make sure that your insulation is very good first, and that you get an air tightness test done to ascertain how air tight your house actually is, rather than how air tight you may like to believe it is.

As standards go, I would familiarise your self with passive house standards, and strive to apply those to your house.

Hope that this is of some help, please be assured that i am not trying to dismiss your idea, but rather I am trying to ensure that you spend your hard earned in the most beneficial way.

There has been a lot of discussion of these systems on the www.greenbuildingforum.co.uk
