The government & air / ground source heat pumps

Ok… you have no idea how these pumps work or the running’s involved. Dra is right, they’re electric heaters….for every 1Kw of electricity you put in… you get 3Kw of heat out.

That depends on the heat transfer coefficient, which is determined by the design of the heat pump, and mostly by the temperature and humitity of the air.

Under an ideal situtation the coefficient can be a 1:3 ratio, but that’s when the air has a lot of thermal energy to extract. That’s why they are used as air conditioners.

I ask you again, if the outside air is cold, where does the energy come from?

Fishy’s comments (in italics) addressed one by one. You can’t beat a bit of structure so i’ve listed them to make it easy for fishy to reply.

1. Would you like to see my HNC in fluid mechanics from Brighton Poly or maybe a few of the other certs I’ve done since then like OU stuff or NVQ’s?

Aww…go on then fishy. Certainly gerry boi would like to see them as well. Chuck your credit/debits cards in while you’re at it.

2. Bio mass isn’t a new idea…its just a new name for an old one. Gasification was used to run vehicle in WW2.

You’re completely missing the point of biomass being a fossil fuel BURNING process and now trying to justify it by saying it’s been around for decades. I say again, you’ve invested in an antiquainted system and also you’re promoting it to other chatters!!!

3. Vertical boreholes require a geographical survey.  I can think of many places were you couldn’t place borehole due to the ground conditions. And anyone who’s done pile driving will tell you its not just the ground you need to worry about

Here’s a short educative video on bore hole DRILLING. I emphasise the word DRILLING because that’s how they DRILL a bore hole. and with mini boring machines, not through pile driving. Hey fishy, wouldn’t it be great if all new housing estates had bore holes drilled while they were being built eh? Now that’s what I call planning.

As far as you’re ‘whole lotta trouble’ item ..well…I think you’ve ‘done a drac’ and used one  incident to trash the entire approach of ground sourced heating. Of course surveys need to be done but if all new housing developments included ground source heating then these additional costs would be dramatically scaled down and the payback would be enormous and beneficial to the planet. Unfortunately the only trend seems to be installing noisy and inefficient air sourced pumps into new houses.

4. While you’re sat there digging holes…. the heating industry is carrying out research into reclaiming  methane gas and heating systems for manufacturing.Cos everyone poops

Personally, i think this idea is a load of shit but i refer you back to item 2.

So, to summarise, thermal energy from the sun heating the ground from which the energy is extracted by heat pumps powered by wind, solar or tidal farms. A 100% green, electrical process. Not one gram of carbon or greenhouse gas in the entire cycle. Unlike your wood or poop options.

awww. gerry boi…i’ve missed you so……almost as much as a borehole in the arse.

But you’ll know about arses don’t you gerry boi…

gerry boi, i’ll remind you that this post is about heat pumps.

Now, while i’m sure you get pumped every night, could you please stick to the subject.

You must have a wealth of knowledge to share with us.
