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.

Seeing as you have time to post a pic of your ‘JIB PMES cscs’ card DOA would you be kind enough to post a pic of your HNC in fluid mechanics from Brighton Poly, OU ‘stuff’, and your various NVQ’s. 

Could you be a dear and put all of them in the same picture and obviously with your name and details redacted. 

Apologies for the font.[Read more]

This thread is amusing even by JC standards. Especially the reference by DOA to the cscs card and which a monkey could pass wearing a blindfold.

1. You have to drill through a wall panel that you suspect contains an asbestos material. What should you do ?

Give one answer

A. Put on an FFP3-rated dust mask before drilling
B. Spray it with water…[Read more]

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]

Thank you all for this really informative and useful post.

May I ask when you mention about more efficient radiators , could you please provide some makes or models you would highly recommend or a website where you can compare radiators and view their effectiveness / efficiency?

thank you again 👍🏻

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]

P.S  Wouldn’t it be nice if everything that is electric (eg heat source pumps) were powered by our wind, solar and tidal farms.

No BURNING anywhere in that process…eh

Hmmmmm

Fishy – You’ve wasted your money installing a fossil fuel system – biomass – and you’ve done it because it’s cheaper for you to run. Bully for you. It’ll be an antique in 10 years times. If everybody did what you’ve done there would be no trees and no planet.

I can’t help it if you’re a hack plumber. I’ve come across plenty of those in my…[Read more]

Fishy i want you to go to a mirror look at yourself in the mirror and give urself a big kiss .Life is too short to go on a diet adopt a healthy lifestyle and the pounds will lessen .

I think ppl are all shapes and sizes and when that fat little sperm hit that little fat egg some ppl are destined to be fat .They were fat kids plump adults and…[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 hours per day…[Read more]

…and if you liked that one…

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]

Can’t wait.

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  )

Boreholes are not ‘crap’ fishy.  They work well and you don’t have to go down half a mile. I’m getting tired of your false information.

You’re burning biomass. You’re producing greenhouse gas. Maybe not as much as a coal fired powerstation but you’re BURNING fossil fuel.

As i said, the way…[Read more]
