Suffolk Trading Standards Imports Surveillance Team have detained 973 diesel heaters at the Port of Felixstowe over the last two months

All products were found to be unsafe, with listings for all sellers removed on eBay. Consignments arrived at the Port in October and November and were stopped

All products were found to be unsafe, with listings for all sellers removed on eBay.
Consignments arrived at the Port in October and November and were stopped by the team, with samples sent to a test house for assessment.
Each of the products did not meet the requirements of the Supply of Machinery (Safety) Regulations 2008 because they could present the hazards of fire and death due to poor supporting installation information.
Manuals supplied with the products failed to give measurements for installing and did not give the minimum distance the exhaust pipe can be installed from flammable material, or material that could give off poisonous fumes when heated, such as insulation material.
No warning was provided about heat and dangers to the user if installed incorrectly.
Large parts of the manuals were written in poor English and had incorrect words used. The intended meaning was, in some cases, difficult to understand.
Additionally, the products and instructions did not have the name and address of the importer or manufacturer, and did not included the required Declaration of Conformity (DoC). A DoC is a formal declaration by a manufacturer, or the manufacturer’s representative, that the product to which it applies meets all relevant requirements of all product safety directives applicable to that product.
If you have purchased a product that you think may be unsafe, stop using it immediately and report it to Trading Standards via Citizens Advice Consumer Service on 0808 223 1133

Well the product was still on eBay a few seconds ago .So I don't know what to make of your post .

Trouble is there are loads around who would believe what you posted

Not on here, I think.

Maybe I should start my own YouTube channel.

Maybe those came in via a different route? Or maybe some other reasons why?

"No warning was provided about heat" If I really need to be warned in writing that a diesel heater may become hot (hopefully!) then I might be tempted to call it a day and check out...

Wasnt it maccy Ds that got prosecuted for not warning that hot drinks may be hot….worlds gone mad

Does anyone know what temperature the water in the now closed deep coal mines is? Lots of old pits in this area, surely that heat is recoverable.

About 50 oF or 10 oC ( IIRC from my potholing days as a young man ) but most of it needs some serious extraction pumps to lift it hundreds of metres up out the pit or to to some where dry for the heat pump to extract the heat .
I suspect though it's more sensible & economical to lower a very long continuous filled coiled loop pipe down into the mine. So that all you needed was to push the heat extracted cold water back down the pipe to use less power .

When I looked into such things about 40 years go, they were recommending a 90 mtr vertical bore of 700 mm with the curled ( like a spring) filled coiled pipe for a 10 kw heat pump if you didn't have the land to excavate a 2 mtr x 2 mtr deep trench system several hundred mtrs long for pair of over lapping laid in continuous coils water pipe system .

Saw a innovative self build program Sky TV 10 or more years ago where the guy had about nine 90 foot deep bore holes in the ground under the footprint of the floor slab .
Into which he inserted fuse welded alkathene water pipe coils inside rebar frames and then had them lowered down the holes . Putting a mtr dia or so wellhead pipe shield at the top, then took all the now insulated water pipes back to the manifold area and back filled the borehole voids with a lean mix liquid concrete .

IIRC his biggest heating & hot water bill was less than a tenner a quarter .. but his novel extraction set up cost him around £130 K

Haven't read the whole thread, but I've seen good info and downright nonsense

UK heat pump should have a scop of at least 2 when it's -3, it should work perfectly fine down to -5, only needing the immersion when temps drop below this

I'm no longer doing domestic but I have around 15 schools running air source heat pumps. My laptop has been on the BMS monitoring page constantly and we have had 2 that needed the immersion for the hot water. 1 used it's gas boiler yesterday but the internal temps dropped, turns out they had a concert and left the main doors open

Very hard to diagnose the problem on here, I'd expect a domestic system to cope in these conditions though

Tempted to think you guys don't get access to the better heatpumps we do in the nordics. I mean they're on like every other house here and people like them. Or your houses need to be better insulated.

Because we get all the rubbish supplied and installed by "specialists companies" that spring up on the back of green subsidies and other tosh thats rolled out

So reading between the lines they were only considered unsafe because the INSTALLATION instructions weren't safe. Don't run the exhaust near combustibles etc etc. I would have thought the majority of people installing these could work that out for themselves?

These are the same people who send badly loaded pallets via your network…..

I'm sorry but that's tosh

The UK manufacture some great heat pumps, we can buy whatever we want. Some are better than others but that is the whole nature of markets

Whooooooooo ! the not in stock small oil heater has just arrived, the box is in good order . I'm letting it defrost in the bedroom as it's too cold to play with & in any case it's too chuffing cold outside around minus 4 plus a bit of bone gnawing wind chill to be trying to install it right now .

Though it does make me wonder who answered my question when I asked the eBay seller , "What is the maximum lift of the fuel pump? "
There were several click here buttons in what looked to be an official eBay reply saying it was no longer available & inviting to me to go and buy a bigger more expensive heater .
Happily I don't play such games so I'm still £150 or more in pocket .

It's a jelly battery set up I'll be using , but I'll try to remember not to eat the cherries and ice cream on the top .

Oh, and another safety warning, the air inlet pipe will be firking cold to the touch, this time of year. Your fingers might freeze themselves to it!!

What is this "defrosting in the bedroom" of which you speak? I got up for a pee in the small hours the other night and my phone was showing -7, and with one single glazed sash window and a double glazed velux, I wasn't hanging around. The only heating upstairs is electric panel heaters and I'm too mean to run them all night. Roll on summer!!!

I think I’d have just wet the bed and rolled over to find a dry bit!!
