No, that was a general comment to highlight how hard it is to compare different technologies. But out of interest, what boiler did you get fitted, and how is it working out, as cheap to run as you imagined?

It does. Tim whatever his name was has already blocked me. Shame you do not want to engage in the heat pump debate posting up biased, unfounded, opinions, and then not backing them up is now called trolling.

So a basic replacement then. Isn't this like replacing a broken ten year old car with an identical, ten year old car, but with lower milage. And this is like replacing the broken banger with a new Tesla. If you really want to compare prices, you have to do it on the same basis, not on an arbitrary one like power output only. A better gauge would be installation cost / (running cost / annual energy yield)

It is not often that Cornwall gets hot. But one thing we do have on the 20 days a year without clouds is very powerful solar radiation. Now that we are in an area that has been issued with the countries first 'heat' warning from the Met Office, and I know I am going to be working in extreme temperatures tonight, I thought I would try and keep my bedroom a little cooler. Total price <£

Why 'annoyingly'? With the current system of gas boiler installations, there is probably very little thermal design involved. This promotes inefficiency at all levels. It also highlights a problem with not having to pay a direct price for externalities, such as climate change mitigation and infrastructure updating/upgrading.

Why would you not want use of a drive that is up to current regulations. I would rather pull out of my drive in a safe manner than hope a driver as bad as me was coming along the main road.

Ok, to clear this up, and stop you trolling, can you show us your heat loss calculations for your house, and your DHW useage. Then show us all why it is not possible to have a HP system deliver the same outputs. Then show us the difference in running costs, and installation cost, rather than vague and misleading statements. If you are not willing, or able (which we both know is the real reason) to supply this information, then you don't have anything to contribute.

I added mine for a laugh.

That is Dave Jones trolling again.

Pulled up easily enough.

Looks like it is. Going to kill it all the same.

I shall have a good look in the morning. The rest of the plants need a good watering.

Pretty sure it is knotweed. May burn it. Or just take it to the dump where they have a special place for it.

You need to look at the volume to solar exposed surface area. The larger the building, generally, the less exposed area there is, this limits the energy transfer. Best to just do some calculations and scenarios for different conditions. I think Jeremy Harris's spreadsheet can accept solar inputs.

If you assume that a normal wall needs to cope with low losses when it is 20⁰C inside and 0⁰C outside, then you can work out an acceptable loss for a floor slab that may be 35 to 40⁰C but the ground will probably be no colder than 10⁰C. So 50% greater losses, and no solar gain available except what shines through windows in the summer, which is of no use. Can you not put in conduit for all the buried cables, costs very little and gives you flexibility in the future i.e running cable for a car charger, shed, ASHP.

Not really enough in normal circumstances. Yes it does, your electrician will know all the regs about it, I hope.

Do you know how an ASHP really works and what the limitations are? And have you done a heat loss calculation?

I am way to young to know, but is this 5A circuit wired into the normal lights and then just one fuse for the two circuits? I appreciate that some houses are smaller than others.

Welcome Ask yourself how much insulation you can get between your UFH pipes and the ground, you probably need 200 to 250 mm. Sort out all the other thermal elements and you won't need heating upstairs.

Welcome. Be vary careful. I think a small time builder converting commercial properties to flats open to a lot of abuse, rule misunderstanding and fraud. There was a reason no Fensa certificate was available for my front door, the fitters were crooks and conned the previous owner. You may be better off walking away now.

I know a midwife who was called into casualty to 'help the fire man' remove a pipe fitting from a young man's member. When she got there, there was also hematology, trauma, neurology, police, press, Et Al. all giving advice. Not sure if a blacksmith was called.

Mate of mine got superglued to a toilet seat. I once saw cling film on a urinal. But the best is my sister. After a long drive down to the South of France, she was busting. Ran to the loo, flipped the lid, sat down and let it flow. She forgot it had a secondary lid to reduce the odor when left unused for months. She may as well just have done it in her pants.

I found a broken one in my garden.

Don't know, I can't get into others tiny minds.

Does seem strange that it found its way into my planter. Right where I found the crossbow bolt.
