Snake oil or worth a look?

If it sounds too good to be true ......... etc etc etc


Its the '' magic '' in the title thats the give away.

dont bother its like the 500watt plug in heater that heats all your house like this garbagehttps://topconews.com/JnXN/en-heater-pro-x/d1/avoid-huge-gas-bills-this-winter-1111?c=1384769&b=&s=msn.com

With a boiler flow / return and a rad flow / return it looks like a heat exchanger to add extra rads?

I may be well off the mark as I’m not a plumber but I’m intrigued.

Edit. Am off the mark. Well wide!!

Google it. Police raids and OAP scams! Better than a night in front of the TV

Does it come with free magic beans ,,,

my gaming computer gives off more heat off than that thing and its also cheaper on electric

even had that argument on another forum as well as some idiot pointed to it and stated it could heat a whole room up

A 1 Watt heater will heat a whole room up, just not by much!! ;-)

I read an article recently which said that if you’ve a condensing boiler it will become more efficient if the outflow temperature is reduced to around 60 degrees, I thought it try it but I’ve a hive thermostat wired in and turning the output temperature down on the boiler has no effect, it heats at full power until the stat sees 17 degrees then shuts off.
This device appears to claim that it will reduce the output temp to 60 degrees, I’d be interested to know from a heating engineer if there’s any truth in the claim that a condensing boiler is more efficient with a lower output temperature and if so how can that be achieved

if that was the case ,, and it was noticeably more efficient dont you think thats the way it would leave the factory , along with a big advertising campaign extolling the virtues of its low running costs and high efficiency ,,, just my thoughts.

Radiator has been turned off in the office for years

My old 2009 rig used to run very hot. Dual GPUs at around 100deg c. Each cpu used to run at about 90 kicked a shed load of heat out of the back like having a fan heater under the desk

Yes I do, but this particular news feed was doing the rounds a few weeks ago so I thought I’d ask the question, it did say though that if there’s lots of rads the lower temperature might not be enough to heat all of them up to an acceptable temperature, it’s not my area of expertise hence the question

ive got 2 graphics cards one that i use the other one is i dont want to fit it as im cooked out of my room sometimes

the one im using is a 2gb gcard with fan and it really pumps the heat out of it

the other is roughly the same but has 3 fans on it

the room isnt a small one either its about the size of the living room note our rooms are large 16ft x 14ft

Does anyone remember the ceramic heater called the micro furnace ,,, it was an early ceramic ultra compact room heater ,,,

you dont see many of them anymore ,,,, just saying.

there you go

I was thinking ,, Anyone with electric boilers at the moment might be better off using the leccy to mine bitcoin at least it might make some of it back while producing heat

for me its a load of b.s
just a bumf of names and jargon all to con buyers into buying one
its the same with boiler engineers interfering with them as its got to eco'ed nowadays whilst trying to push it beyond its engineered state when it was made
had it with local council they messed with it and it was worse than it had ever been i corrected it and made it even better than before

had a bust up with same fitters and told them to leave as there bodging some guys was ok this guy wasnt the interesting part when id reported it they went through everything
fitted new flue run a full diagnostic of the boiler serviced it to the eyeballs
same with gas fire

last time i had it serviced they was done in 2 hours all of that took half a day with 6 fitters the council officer all speaking under my cameras which also recorde sound as well i also got to find out every detail they was told to make it right and spot on as it will be tested as ive reported them

Had my boiler serviced a few weeks ago Gaz, asked him if it was ok, he said yeh it’s fine, the last time it was serviced was 5 years ago, I’m no boiler expert but can’t imagine there’s much do do, it’s not like there’s an oil and filter change.
However the time previous to that when I got it serviced, the engineer noticed that my gas meter was perforated and leaking gas, condemned it instantly and when the meter was changed my gas consumption reduced quite considerably. So yeh a service now and again is probably not a bad idea.

Condensing boilers work by condensing the latent heat out of the flue gas as you get water vapour forming as part of the combustion process. If you get the return temp low enough the water vapour condenses out. So its efficency relates mainly to the return water temp but the lower the flow temp the the lower the return temp is so more water vapour condenses out. Best is direct weather compensation but you can turn down pump speed and increase temp drops over rads to reduce return water temp or turn down flow temp.

The most important temperature is that of the return water to the boiler. The lower it is, the better the temperature difference to the heat source and therefore the higher the heat transfer. It follows that lowering the flow temperature will help but you always need to know what your system was designed to operate at. Conventionally heating was designed to operate with 80 C flow and either 70 or 60 C return and the radiators would be selected to suit. Condensing systems are often designed with a flow of 60 C and a return of 40 C which gives a good compromise between boiler efficiency and radiator sizes (in a house with modern high insulation levels). If you subsequently reduce the flow temperature then the heat output from the radiators drops considerably ( look at radiator selection data from the manufacturers and there will be a whole load of correction factors to apply to the outputs for differing temperature. These are based on the difference of the mean water temperature to the space temperature). This is why underfloor heating is good with condensing boilers as it will probably have a maximum flow temperature of 45 C and a corresponding very low return temperature and hence the boiler will operate continuously in its condensing mode and therefore very highest efficiency.
Also important to ensure that the flow temperature remains sufficiently high to heat the domestic hot water if this is provided by a cylinder.
Would be interested to see the details of the Hive thermostat if you have them.
