Ok, thanks. Possibly I didn't make the joints properly, but I did both ends in the same way, about 5 turns of ptfe in the correct direction. But both rads leak from the left end and not the right. I've fixed it now by using the insert from the old radiator instead of the screwfix one. The...

Hi, I've got two new screwfix Kudox radiators the same size, both are leaking from the threaded insert where it joins the casting. I installed with ptfe tape, and used the same amount on the other end. Both rads are leaking from one end, not the other which suggests it wasn't a great batch. Is...

Ok, thanks. I didn't know about TRV heads. Generally I've not considered programming heating, I only switch my CH on and off manually. When I had it on the timer one winter my bills went up by about a third. For a Victorian 3 bed terrace my total gas consumption was about 9000kwh last year...

Right, so maybe this is where I'm calculating it wrong? This is how I've got these figures. The radiator in the back bedroom is a one fin 1m x 0.5m. The closest I can find is this 1m x 0.6m radiator, https://www.directheatingsupplies.co.uk/stelrad-elite-radiator-p-600-x-1000 rated at 1400w on...

To be clear about how I arrived at that "1/4 kwh compared to gas" figure. Last year my gas consumption was 8900kwh, of which I reckon 8000kwh was CH. The total wattage of radiators in this house is about 6kwh. 6kwh x 6 hours a day for 6 months of the year x 33% of the time is 2162kwh. Close to...

Hmm. Some angry people on a forum after posting a simple wiring query. I have no idea what I'm supposed to be in denial about. If you want to know my reasons for considering infrared heating, it's in the posts above. You're welcome to disagree. But there's no point in getting insulting.

No. To be clear I'm not suggesting a 1kw of infrared heat will majically raise the average measured air temp in the room any more than a 1kw oil rad or 1kw convector. What matters is how warm does the person in the room feel? Like I said before - on a sunny day go from the shade into the sun and...

They do cover this on their site, "Most of other forms of heaters are convection heaters which primarily heat volumes of air, which then has to transfer its heat to the building in order to warm the thermal mass. The problem is that hot air rises to the ceiling (where you don’t want it) and...

Ok, maybe the way to do it. I think I'll have to get the electrician involved, which is a shame if he can't do it soon I won't be able to get a proper comparison with Dec/Jan usage.

The general rule I've read is that providing the infrared heaters aren't under-spec'd they should be 'on' one third of the time https://www.acchaus.com/blog/far-infrared-heating-its-heating-jim-but-not-as-we-know-it/ Requirements for the whole house is slightly less Kwh than total CH radiator...

I wouldn't say it's a lie. The point is a radiator warms the air, and people feel warm because the air around them is warm. But it takes more energy to warm the air enough to have the secondary benefit of making occupants feel warm. Infrared heat warms the objects in the room, including people...

They were easy enough to set up and look ok. But so far, so dis-appointed. I've got the right power for the room size and insulation, more than recommended on both Herschel and other sites selling infrared heaters. But they take longer to warm the room than the CH radiator does, and consumption...

Hmm, yes thanks. I've checked the Salus specs, it says "16A relay switching". A site selling infrared heaters says the Salus is up to 16A, without mentioning the relay. So I'd need to get a mains relay to control the input to the sockets?

Thanks for replying. The supply is a new fused circuit on the circuit board. Only that double socket is connected so far. Heaters are 1 x 600w and 1 x 400w. They're on different plugs, the two in the picture. We set it up this way so I could swap the heaters out for different ratings by just...
