No, that isn’t how they work at all.

The function of a heat pump is to move thermal energy from one place to another.

To heat the inside of a house, they must move thermal energy from outside of the house. If it is cold outside (when you normally want heating) then there is not much thermal energy to pull from the air to move it inside.

The first question is do you want your home to warm up fast or hold the heat long?

Most of the older Victorian building in Brighton use cast iron radiators. They hold the heat longer but take a while to warm up.   Newley built homes with better insulation use aluminium radiators for faster warm up but lose the heat once the boilers off…[Read more]

I love the idea of being a “hack” plumber 

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?  Training & re certification is continuous process within the industry.   You mite be a “graduate engineer” but that only means you can do math not fix…[Read more]

Here a copy of my JIB PMES cscs card.  This wont mean a lot to you…but maybe you should google it and find out before you reply again?   I’m sure you can get one 

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.

With the price of electricity increasing yearly…. you mite save the planet but you wont save money.

Can I can prove what I’m saying…. can you say the…[Read more]

Errrr hmmm……no

The colder it is… the better they work.   If you put your hand behide a fridge you can feel the heat. Think of an air source heat pumps as a fridge working in reverse. They use about 7Kw of electricity which is about the same as an electric shower.

The problem is….  1 Kw costs between 11 to 21 pence.  If you run it 24 hou…[Read more]

Actually they are probably worse than normal electric heaters as the compressor (the thing that consumes most of the electric) would be outside of the house.

If you have an electric oven you might as well just use that as a heater.

My understanding is that air source heat pumps are more or less useless as heaters as when it is cold outside (when you usually would want heating) there is very little heat energy that can be extracted from the air.

They work fine as air conditioners, but for heating they aren’t much more efficent than a normal resisitive heater. You need ground…[Read more]

Well you clearly dont get my point …..

So being a bit of a feminist I’m going to let Chatguide Le tell you why your wrong :)

(Her mum had one put in  )

Hmmmmmmmmmmm 

I first saw information on ground sourced heat pumps back in 2002. It was in a hand out from CIPHE and sent out with there magazine.

Since then I’ve spoken to a few UK owners who live in France.  There view was the “bore hole” system  was crap and favoured the trench system.

As we all know if you drill down into the gro…[Read more]

Its not my fault…. they made mars bars SMALLER 

Over the summer months we all become healthier. Enjoying the sun…walking for fun and eating more fresh food.

Its the winter when we all pile on the extra weight  

And while somer cant admit he’s got the same issues cos his mrs is a chubby lover. I’m brave enough too  

This goes back to the original law back in 1967.

Medical science came a long way since then. Today a one week old embryo can be grown to full term in a lab. New cloning techniques can be applied.

The question is…is it right?

When do we start being people and not lab experiment’s?

I don’t agree that being able to survive on your own is the correct criteria.

Humans don’t really meet that until at least the age of 3 years. You also raise issues about whether people in comas or other vegitative states have human rights or not, as they would be unabled to survive on their own.

Why?

It is very clearly murder at some stage of development.

I thought this debate is about at when that stage is, not if murder should exist or not.

I’ve seen some people say that post-natal terminations should be legalised, but I assume you are not one of these monsters. Would you agree that terminating a baby at 9 months is murder?

I don’t believe that parental status is termined by genetics.

This is what I have said in the past.

I believe the Texas law states it is illegal if a heartbeat can be detected, which is usually at 6 weeks.

I don’t nessersarily agree with this, your status as a human should be determined by the existance of a conciousness in some form, not by a heartbeat. If your heart stops due to a medical condition do…[Read more]
