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.
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.

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 ??

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 non stop…its about £24. Even if you run it 10 hours a day…its still £10.
But you can work out the cost yourself using the link below.
While I applaud your attempt to bring this subject in to the JC domain, I must question the accuracy of your data. As an example, you’ve almost totally discounted Ground Sourced heat pumps because of the area of garden they need to install the underground pipes.
The favoured method in this country is to use a bore hole whereby the pipes are vertically installed in the ground, not the horizontal way in which you describe, A borehole installation takes up far less footprint and is less affected by seasonal changes.
As for your preference for biomass heating: well, if i had a choice in changing from my gas fired boiler to a green solution, I would choose a ground sourced heat pump everytime because the heat source is totally free and totally green and doesn’t rely on so called ‘sustainable’ biomass fuel sources (trees etc). The only energy needed as in all cases is the electricity to pump the system. The installation cost of all of these green systems is another matter and that is where I believe the Government should be driving industry to bring affordable systems to market if it is to meet it’s climate change targets.
You are right about more efficient radiators. In fact increases in efficiency are needed in the whole thermal supply chain and particularly when it comes to better insulation of our houses, new and old.
