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 same?
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
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 time. I’m a graduate engineer and take everything back to first principles. The first question is the heat source. Heat from the ground is totally sustainable and free. I’m not interested in your 1kw in 3kw out primary school maths. Of course that happens because why would we be doing it in the first place!!!!. The only 2 points i’m making is that you’re BURNING fossil fuel and I’m wishing that ground source heat systems were more affordable.
btw – still waiting for someone to tell me borehole installation is ‘crap’ as you put it.
Here’s a quote from the greenmatch.co.uk site for you to ruminate on:-
Vertical boreholes are good for small or limited areas, and although it bears high installation costs, borehole heat collectors produce a higher heat yield per metre, compared to horizontal collectors, which entails a better energy efficiency rate.
Maybe you ought to tell greenmatch that they are wrong and flash your card at them as well. Being the expert that you say you are, you will know that the depth of the borehole OR the area of a horizontal installation are matched to the energy requirements of the dwelling. Now that makes sense…doesn’t it.
Hmmmmmm ??

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
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 a drain or pipe up a home heating system.
Greenmatch is a business referral service. They promote renewable energy systems and charge installers to be “partners”. Its like checkatrade for hippy’s.
Bio mass isn’t a new idea…its just a new name for an old one. Gasification was used to run vehicle in WW2.

And there easy and cheap to build.
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.
And you still cant seem to grasp the idea this heating system isn’t cheap to run and costs will only increase with the price of electricity.

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
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 👍🏻
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.
Radiator design plays a big part too. You want the chimney effect.
Placement of radiators plays a big part too.
I don’t think there a comparison web site for radiators. I cant find one anyway.
Our main suppler is Wolseley and they sell ones from the radiator company

Hope it helps

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.
Give one answerA.

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.
Thanks babe.
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.
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.
Not sure how you think this could possibly work better in the cold, where does the energy come from?
