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.
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.

I note 3 supporters of this post to date. Thank you.
During a normal forum one chat session, one of my chat colleagues voiced their objection to my post. They have a right to do that of course but when I asked why they refused to be vaccinated, the reason given by the chatter was advice from ‘medical experts’. I enquired (several times) as to who these medical experts were and unfortunately no names were offered.
The effect that conspiracy theorists, self-proclaimed medical experts and general do-badders (some of which are sadly in the medical field) have on the wider population is extremely concerning but that is a bi-product of society being more connected than ever before. Most peeps are able to see through the fog of doubt and weigh the opposite risks but a significant minority are taken in by this propaganda and consequently the in-action of that minority impacts the majority. Perhaps the minority should be regarded as casualties of the situation instead of labeling them as ignorant. They would do well however to question the ‘medical advice’ that they are given by a cult who’s motives are totally anti-social.
