Practical economical Idea for reducing heating bills.

The advantages of this system, is that in the summer, you turn it off? Or reverse the fan, to provide cooling to the whole house.

So no point in summer.

Reversing the fan generates cold air from where?


SUCKING walm air, the fan reversed, BLOWS AIR. Are you just being obtusive, or do you really struggle with Science?
 
So it sucks and or blows walm air?

Where does this new magical element change temperature by just going thru a fan?

PhilipClarke, I'd love to take this idea further, when others, are strangely mentally disagreeing with it?? I think it's a great idea. You and me might hook up? Recoup lost heat into the home is a great idea, and has many possibilities. PM me.

In simple terms, your loft is hot, as heat rises...., the fan draws the heat that is then distrubuted to your house, this is then redistrubuted into your house, as heat. In summertime, the fan is reversed, so blows cold air into your house, even though the loft space is hot.

A fan sucking through a fan, removes heat from the space. A fan blowing into a hot space means the space is cold. Simples.

Nope, blowing warm air into a room does naff all.
You really need to look into what heat exchangers are and how they work .

This part of the system was never designed to do summer except to use it to pre heat hot water for household use. I wouldn't cool a house with this product and never said so. In theory though a low powered pump could be used to take an existing hot water radiator system and pump it under the garden and reduce it to about 12 degrees in summer but that's quite pricey by comparison and would probably need a manually turned divertor valve and there's probably all kinds of byelaws about that one, the the radiators would become reverse convectors as they would be lower in temperature than the air in the house but ideally you'd need to place them on the ceiling because of the way convection works as otherwise there would be a lump of cold air near to the radiator and floor, since that's the way thermodynamics works. I'm not putting this forward as an initial suggestion/ product to build the business, since it's moving away from the fundamentals of lower costs, although it would be cheaper than using a heat exchanger in reverse to provide air con, I don't think it's needed in the UK in residential homes.

@Moody, your settings mean that only friends can send you PM's
 
So pumping hot air into a room does nothing?

It certainly does not cool it.

Worked it out yet?

Actually there is a way in a well ventilated room, you'd assign a room for clothes drying and then pump the hot air towards the wet clothes, the evaporation would use up the hot air energy (and cool the loft space) and as the steam took drew in energy from the surrounding area to get back to water (there would be all kinds of problems with condensation), you'd get a temperature reduction.

Basic laws of entropy state that things always lose energy so the water vapour will not exist in it's molecularly excited state, you'd "bump" it vapour and it will condense so you could get a cooling effect from hot air but then that would waste the hot air that could be used to preheat the hot water supply or provide night time heating because the UK ain't that hot.
 
So you could only cool your house if you had wet washing to dry?
Could you not just open a window?
 
The theory of heat exchangers is generally that you get 4 times back the energy you put in

"Theory" never did cut it in reality. :mrgreen:
 
Phil you haven't a clue about water bylaws for preheating water or the need to get wras approval, the whole idea/setup is laughable.

I don't think it's sensible but it's has a solid scientific foundation, the same principle is made to super cool matter by bumping up it's energy state and then getting the energy release to a level that was less than the initial energy, a recent application was in the production of bose-einstein condensates at Durham university which was previously though to be impossible.

No I don't have an idea about water bye laws, but then if it's already been worked around I don't need to. You don't probably know why a nuclear reactor has uranium in it but doesn't explode, but it doesn't stop you using the electricity. I suggest you inform the companies already manufacturing the products similar in theory that the idea is laughable. I am well aware that building regulations exist, I'm also aware that the website pulled up by someone earlier has already had there system ratified, as have the people with expensive heat exchangers, this is more economically viable.
