The pride of High Wycombe.

Was it installed by Borborygmi.

Having worked for an MCS company, I tend to agree that some are good. Trouble is, you don't know they are bad until it goes wrong. And claiming via the MCS is set up to be impossible.

All sorts of different plans, and I have never understood one of them. http://jspinderplumbingandheating.co.uk/zone.php They seem to me to be similar to choosing a Porsche 911, or an iPhone.

Lots of details here. Trees are an odd thing. There are not many down here, but loads up in Bucks. I often wonder if our policy of over protection has hampered replanting.

Decentralised Mechanical Ventilation and Heat Recovery. AKA Single Room MVHR. Who makes them, do you have a link please?

Yes, you are the customer.

How would you set it up? 3 scenarios: Lowest running costs Guaranteed output Lowest CO2e See how their answers compare to yours.

https://www.forestresearch.gov.uk/tools-and-resources/statistics/statistics-by-topic/woodland-statistics/ UK, as we know it, has been historically low in tree cover for centuries. https://www.conservationhandbooks.com/woodlands/a-brief-history-of-woodlands-in-britain/

Money does grow on trees then. Something to chat about with Kier as he sits in the back of the police van.

Too right. You would not fit a system that would not work.

Would run the risk of the return temperature being higher than the HPs flow temperature, do as you say, pointless. Maybe if the HP side did an hour or two of DHW heating, then disconnected and the oil took over, it could be useful. But easier and cheaper to just use the imerssion heater to top up. I can't see much use for them, but they will be fitted by lazy plumbers that still think that HPs 'are not there yet' AKA uneducated tossers.

I understand this, and it is probably a cheap option. If/When HPs come down in price, and assuming enough room, hybrids, like the vehicle equivalent, will become unnecessary. We don't. I know this is just a translation thing, and I know you have not typed what you actually mean. So for clarity. They work at a higher CoP when the output temperature is lower than a thermal boiler. The output, in kW, regardless of temperature is to do with mass flow, lower temperature, more mass of fluid needs to flow. Then there is the energy, the kWhs, that is power (kW) times time (h). Such a shame we don't use joules for energy.

Timber farming is like any other farming, an industry. Now if we dislike the way farming is done, or any other industry for that matter, then boycot the goods, set up pressure groups or become a politician even.

Ah, good reason. Though my car windows don't bother me that they have steel and moulded plastic, and I spend a lot more time looking out of them. And they are heated, open fully electrically, and have wipers to get rid rain, and washers to get rid of dirt. Funny how unimportant we think some things are, and how important other things are.

Why not just aluminium frames then. They can be foam filled to improve thermal performance.

I would hope it was used to minimise overall CO2e emissions, or the whole thing is pointless. The use of HPs is to minimise CO2e after all.

I will have to ponder this. I suppose the UFH is running, on average, cooler than the BT. Probably does not make much real difference in normal usage, but may at the extremes.

What is the advantage in covering timber frames with aluminium? Never really understood this, and I understand composites quite well.

With this set up, is there any flow advantage to having the Ts at A and B flowing strait threw and the buffer coming off the Ts? Whenever I see a bend or junction, I just see slower speeds. Hope that makes sense.

There is a unit for breathability. GNs/kg.m Ask manufactures what the number is for their coatings.

@Mike_scotland Ask your builder for the room by room heat loss calculations.

@ProDave There is a similar joke about what going to prison for drugs offences does to you. The comparison is a 5p and a 50p piece. Just the shame as what is happening here, being shafted.

@Mike_scotland There was no response, just my quote.
