Hello everyone Everyone who explains in comments that the heat pump is 3x more efficient. Have you ever looked at what SCOP is? The colder it is, the more your 400% becomes lower than 150%, precisely when the heat pump needs to work the most.

Does it draw less wattage when the thermostat is set lower ?

If it TAKES less CO2 to manufacture an infrared system then it is obviously inferior. The problem here is that you probably mean it "produces" less CO2 during the manufacturing of bla bla bla. But you didn't say that, you state the opposite, which makes your product bad for the environment. Not to mention production is just a tiny part of a products CO2 footprint, the origin of the energy you use to run the system is much more important and makes the initial production footprint irrelevant in almost 100% of real cases.

Terribly bad commercial. The answer is obviously because heat pumps are MANY TIMES more efficient.

Fire your marketing department for idiocy. There's better ways to sell IR panels than straight up misrepresentation.

That's nice and all, but doesn't a heat pump also have the ability to cool the place during the summer and such? Just wondering how does an IR panel perform that function.

...because unlike radiative heating from IR panels which are up to 100% efficient, a properly installed modern heat pump is 300-500% efficient. If you get an average install 400% efficiency, and require about the average heating over a year of 10,000kWh @ 22p/kwh: - Radiative heating using IR would cost £2,200 - A heat Pump would cost £550 Your IR panels have a use case, but don't pretend they aren't 4x less efficient to run than a properly installed HP system.

Running my 12K mini split off solar. Which was an easy DIY install. Maybe you should compare apples to apples? And it is producing at least 3x the amount of heat energy for each unit of electricity that goes in. Oh, and did I mention that it ALSO cools really well?

Wow. I didn't know that the sun was a relatively poor source of infrared radiation. I didn't know that infrared radiation can travel thru your body. The Greenhouse Effect is about atmospheric water-vapor, CO2, methane, ozone, and CFCs trapping long-wave infrared radiation. Encyclopedia Britannica, or NASA for Kids explain it well. You mentioned that infrared it goes thru one's body, perhaps it can go thru foliage? We are 'cooling' urban areas, using vegetation and trees, which emit Greenhouse Gasses and trap infrared radiation from exiting the Earth's surface to space, thus heating the troposphere. It seems foolish to use of shade trees, and evaporation (phase-change temperature drop of water-vapor) to perform this task, as heat and temperature are not the same, and precipitation (the reverse phase-change, going from a gas back to liquid) it actually releases heat, if I recall my chemistry correctly. Consider the 'Heat-Index,' as arid climates are not as dangerous to humans during heat-waves because there is less water-vapor, a common Greenhouse Gas, and dry climates allows humans to perform evaporative-cooling in the form of perspiration . Another example is exhaust gas re-circulation in an internal combustion engine. Adding (cooled) CO2 and water-vapor from the exhaust to the fuel-charge allows the combustion chamber to operate with greater efficiency, at a lower temperature, thus saving fuel, and engine wear while doing more work - a kind of Greenhouse Effect. Thanks for sharing.

I was rather concerned about Herschel’s approach to another KZfaq video that did an assessment of the infrared panels and their claims , to the point that I thought maybe intone be buying their units .

Show us the facts and figures. Where are the spreadsheets? 1. What is the heat loss of the building? 2. How many kWh of electricity are being used? Average for Jan, Feb or March? 3. What was the cost of installation?

A good compromise is to have air source heat pump (air to air, eg air conditioner) plus some infrared heaters in the seating area of your home (or other spot areas where you stay still for long periods). The heaters give a nice direct heat that's cheap and adequate, while the air conditioner just takes the nip out of the air. Air conditioning units aren't too expensive to buy/have installed. The infrared heaters consume more power (per square meter), but because they're directional, and higher heat, they're perfect for directing at your body and you don't need to heat up the entire room. The air conditioning unit struggles in the dead of Winter to keep the home above a certain temperature, but still gives enough heat to take the chill out of the air, but most importantly it does it very efficiently (lower temperature & lower electric bills). Best of both worlds. You also have air conditioning in the dead of Summer too :)

18 degrees is 18 degrees, still not warm. What's with the neckerchief and wooly jumper, needed personal insulation?

We replaced our gas boiler with ashp and after a year of fine tuning have a very low cost system using the existing rads and underfloor. It's a 1950 detached house with reasonable insulation and new windows. We looked at infra red panels in some rooms but the efficiency of heat pump worked out much cheaper especially when we shifted our tarriff to octopus Go which gives several hours of very low cost energy. A couple of weeks of disruption vs 20 years of higher costs every year.

Absolutely agree! Wish the system had been around 20 years ago so we could have installed it as our main heat source- we’ve just installed one of the same units, as in the video, a supplemental heat source and it is brilliant! Why it’s not more widely known about, I do not know. And so much more efficient than our wet underfloor heating system.

Hello. I cant seem to find your HS700w model heaters anywhere?

too good to be true.

Air Con units would have worked, much cheaper and still benefits of a heat pump. Enough cash left over for solar and batteries too

Selective use of radiant is great. Radiant IR panels don't cool a space though. A Heat Pump doesn't create (much) heat but it moves heat from one space to another and it does it efficiently with a Coefficient of Performance of 2 (200% to 3.5 (350%) depending on ambient temp outside relative to indoor desired temp (Delta T). A Radiant IR panel is COP 1.15 (115%). So for every unit energy you give it you get a bump of 15%. An Air sourced heat pump would get a bump of 100% to 250% I would think a Heat Pump with some spot IR panels for that nice sun like radiant sensation is comfortable environment. They can be used when the Temp is extremely cold outside wit equivalent COP of heat pumps.

Metal walls ceiling and floors and a low level microwave generating appliance creates a lovely inner warmth the microwaves basically warm the person not the air and furnishing.A lovely warm feeling through and through.

Builder, outside Boston. Our cost for air to air minisplit are $2500 installed for 18000 btu unit. Enough for well insulated 2000 sq-ft home. Radiant floors are not noticeable warmer in a well insulated home. 72f floors to keep room temp 70f.

We have a late 1970's bungalow that we gutted and re-planned 2 yrs ago. We out in a new gas combi boiler with underfloor heating across 2/3 of the bungalow, and Herschel IR in the two south facing bedrooms, and just about to put one a mirror one in the ensuite. We faced the similar challenge of the solid floor and opted only to take the screed off to get a foil back foam insulation with the UFH pipes and a Kronoswiss composite floor. We are about to do the next phase of adding an extension to create a lounge/study/utility and this will be to Passivhaus standards of insulation including the floor where I am considering foam glass instead of foam board, and looking at a solid block wall with insulation on the inside (but this has not been done very often and have slight concerns about the interstial condensation). I have been thinking about not putting in UFH because of good floor insulation and only going for IR panels. I looked at a 21 panel solar and 7.5kW battery solution but chose to use the same money (£17k) to buy two listed battery funds (£7k) on the London Stock exchange and spend the panel money split between Solar and Wind listed Investment Trusts (£10k). A quasi-off set approach - dividends pay the electricity and gas bills or contribute to it, but currently re-invested. The great thing about this approach is the capital should appreciate over the same lifetime as the panels (25yr). If we ever move my capital comes with me and also not subject to technology obsolescence, or maintenance (battery will need to be replaced a couple of times in 25yrs and the invertors I think every 5-7yrs). Another option would be to skip the panels and use the batteries with the flex tarriff. We also replaced the existing double glazed units in the original windows as this was more cost effective than replacing the window whilst we consider external insulation in the future. Currently re-insulating the loft with 300mm of STEICO wood chip batts and thermafleece membrane as the original insulation was trashed in the rewiring. We have installed is a series of AICO sensors and gateway so I can see online the temp/humidity/CO2 in all the rooms, and have used this to try and sort out issues like mould, I have one in the loft so I can hopefully see the insulation makes a difference. What has made the difference was a DEMAC dehumidifier set at 55% set centrally, this will be replaced by an MVHR with the next phase. Interestingly, I have just calculated our gas and electricity use for the year and it is 62.5kW/sqm.

Have completed a similar install on my 1970's house. But without adding any more insulation (something I have concerns about) Again using Hershel, who I strongly reccomend. So an install of all IR heating panels and batteries and some solar again cost a similar amount to what an air source heat pump would have cost. The running costs through the past three months (Nov, Dec and Jan) was about 2/3rds of what our previous central heating would have cost. And agree with all the comments made here. A couple of other points as the air isn't being heated directly, the air temp is a little lower than with a wet system, which reduces the likelyhood of condensation and mold growth, and as convection currents are not created it is generally better for people with asthma and similar.

When you have insulation that good, probably fan heaters would have worked too.

Very interesting and informative video

A very informative video - thank you. We too have a 1950's retro-fit eco bungalow, but have incorporated underfloor heating driven by an air source heat pump, in addition to solar panels and batteries. Our approach and your approach demonstrates the old adage 'there is more than one way to skin a cat'. The one thing I would highlight, in your 'Eco house', is the wood burning stove. All available information suggests that these are majorly negative in terms of particulate pollution. Leaving on a positive, I completely support the approach of retro fitting as opposed to 'knocking and re building'. Rebuilding is both environmental and economic madness, on the macro scale. I agree that Herschel Infrared heaters are great too!

Thanks for the very interesting video. My heat pump costs £250 to service each year and the whole system cost £15,000. Fortunately the renewable heat incentive scheme (RHI) covered most of the cost of installation, otherwise I would have gone for radiant heating!

Are these safe for children in the house? E.g. if they touch it ?

Zero light? How does that work?

I am so skeptical with infrared heating, is there not some sort of "try before you buy" or some place we can experience what these actually do? I know they are reasonably priced, but i don't like to waste money on what i can assume is experimental heating, given the lack of coverage or knowledge people seem to have with these sort of heating. I've done alot of research and a few things keep popping up. One is that some infrared panels have a built in thermostat that is on the back of the unit, which gets hot and makes the thermostat essentially useless Is there any testing done to ensure the heat generated by the panels does not cause skin burn? Is there any testing done to ensure these don't damage your eyes which alot of people seem to talk about?

I wish the government would offer incentives to install infrared heating like they've done with heat pumps.

Also if it hasn’t been mentioned, infrared heaters give help with th body’s vitamin D production, especially helpful in cloudy climes.

I have replaced all my heaters with Herschels IFR panels and they are amazing. The only downside I have found is that if I have 2 radiators in the same room you can individually control them, unless you switch them off at the switch it self

Speaking from experience, you produce very little solar electricity four months a year - the four months you really need the heat!

Wow, how expensive our air source heat pumps, if a large solar + battery system was cheaper?!?

Why do Herschel use longwave radiator elements instead of short wave heaters?

I cannot recommend Herschel (and infrared heating) highly enough - a very effective heating solution. I had it installed two years ago and love it for all the reasons Darren Jones outlined.

The product is certainly beautiful, but is it really more efficient? Please let me know if I've made any mistakes below. IR heaters are effectively resistive heaters with some losses to convection. But they are basically 100% efficient. Convection heaters are the same but don't direct the heat so loose to radiant heaters. You claim 50% energy reduction compared to radiant heaters. But with air source heat pumps having COP average of 2.5 in my climate (North of England.), that gives a 60% energy reduction compared to convection heating. Ground source have COP of 3-4 so at least 75% reduction compared to convection.

Well thought out & logical. Having worked on a few heritage buildings in the past, it can be a challenge to get something technically correct but also in keeping with the buildings character.

Churches and homes used to have self heating systems that utalized aethericnenergy collection to ionise air in the ‘chimney’. This ionised vaccume would either push hot air into the building in winter or the system reversed to bring cold air in summer. Remember HIS STORY is not OUR STORY

Nicely done Matt 😊

Are these medium wave heaters?

Love the serendipity of him accidentally discovering the thermometer went up highest when placed beyond the red.. it’s noticing anomalies that leads to discoveries.. (I’ll end my rap there!) I’m using Herschel IR panels to heat my home and really enjoyed this clear elucidation of your man’s discovery. Thanks+++

When I first came to the UK so years ago I laughed at the radiators as they seemed very old-fashioned. In New Zealand they're only seen on old school rooms or other late 19th/early 20th century buildings. In the UK radiators are often placed under windows which is incredibly dumb as any cold air emanating from these areas immediately negates the heating being created by the radiators; a matter of basic physics. Many a time I've been told by people, including, a plumber friend of mine, that this will (blow) the hot air into the room - all with perfectly straight faces. They genuinely believed this stuff.

There heritage lamps really fit in well with Ecocurch.

Recommended this to someone renovating a French 17th century Convent as it would be perfect for the chapel which has a painted decorated ceiling and I know that the owner has every intention of reinstating the chandeliers. Makes so much sense to go the Herschel Infrared Heating system route by combining the two processes.

So thinking out loud here... a conventional thermostat won't work here, because it will measure the air temperature; the infrared is not directly heating the air (at least not intentionally), so I assume that either a) the thermostat indeed measures air temperature, and therefore would not really work well in a larger space, or b) some other assumptions/estimates are used in order to achieve the 'thermostat' function 🤔

So it doesn't heat the air just the body so where not wasting money heating the air , but has a thermostat that works off ??? heat in the room/air... or am I missing something
