This is a really good application for infrared heating. It's not right everywhere, but for a large, poorly-insulated, intermittently-occupied public space it's hard to imagine a better alternative.

@@1voluntaryist Heat pumps are better in most cases due to COPs of 3 or more (3kW heat out for every kW electricity in), giving much lower running costs than any form of direct electric heating (whether it be old fashioned resistance heaters or fancy IR). However they have lower peak output, so where you need an occasional sudden rush of heat (like in a church for a service) they may be competitive due to lower installation cost. Ideally probably is a hybrid solution where you have a small heat pump running steadily to keep the frost & damp away and heat the place comfortably in mild weather, with IR for a sudden boost in the depths of winter.

What I loved most about meeting Simon at St Michael's is that he didn't push for a cleaner solution because it's his job and he's paid to do so, but because he truly cares and can see the value as well as the power and the responsibility that a large organisation such as the Church of England has to delivering net zero. I doth my cap to the Simon's of this world.

Nice video, but you really always need to emphasise in these videos that heat pumps will always be over 3x more efficient than literally any other source of heating. While you might be heating a smaller space with infra red, it really doesn't matter that you're heating a larger space if the heat is a third of the cost with a heat pump. Lots of examples of churches with heat pumps.

Heat pumps are wonderful technology, but heating tons of uninsulated stone to any more than few degrees above outside temperature is a ridiculous amount of energy. Even if electricity wasn't overpriced, a heat pump would still have the same issue as a traditional gas or oil boiler or forced air system. The vast majority of the heat sits up in the rafters or is sucked into the stone. Having been in an uncomfortably hot loft above a cold main floor in giant space on more than one occasion, the radiant heating intuitively makes so much sense. Not every solution fits every application.

If the UK is going to push for greater ASHP rollout, it may be worth considering amending MCS regulations to only require the heat-pump to provide up to, say, 90-95% of the maximum potential heating load. A dedicated half-price socket that an infrared heater is plugged into in the main living space could provide the added 5-10% in event of another Beast from the East, or something along these lines.

​@@Mike__BThey are spending less on electric heating using this method than they were on gas heating previously. Given that electricity per kWh is so much more expensive than gas, this indicates that they are being vastly more energy efficient than they were. On the low carbon front, each kWh of UK electricity produces 82g of Carbon, whereas each kWh of gas produces 185g. So far fewer kWh, and far fewer carbon grams per kWh. Very much more efficient on all fronts.

​@@simhedgesrex7097 It most probably is because they are using focused heat, so they don't have to heat the whole church just the seats (as they showed in the video), so I'll give them that but it's not really and apples to apples comparison on efficiency. Now on the efficiency front it could be they were using really old gravity heaters that maybe 20-30% efficient, then combined with the lack of directional heating yeah I can see why they were paying much more. Does the UK get a majority of it's power from renewable (non-burning) resources? Because I'm not so sure I buy that carbon argument, here in the US water heating devices whether a furnace or a water heater has a minimum efficiency rating of 80%, a natural gas power plant at most is half that efficiency, so there's no way gas would put out over twice the amount of carbon unless your local government is playing a number manipulation game and factoring in a bunch of inefficient devices.

As they teach at school, heat is transferred by conduction, convection and radiation. Then you realise it's not that simple when there's dampness/humidity, and ventilation and frost protection needed. There's also building control and listed building requirements. Looks like they done a great job, but don't know if it's a cookie cutter solution, need someone who understands each building and setting?

Then there's the option of having plain square panels fixed to the walls. Or fly them if preferred. And it's possible to have images on the panels so could always hide them in plain sight. A few religious icons might be acceptable when applying for the church faculty. Send a few examples to the Bishop to choose, which might, possibly, only possibly mind you, stop the nay sayers carping away, as is not unknown. Might be an idea to have the panels coordinate with the hue of the interior stone work. The heat "shines" down from above as if a benison from the Almighty himself sitting in his Heaven. There again some Vicars are perfectly at home with tech such as radio mics bx from flown column speakers or even LED luminaires using full DMX. Anything, almost, to get posteriors on pews and knees on hassocks.

Ive worked in both a stained glass factory and done maintenence in a historic church in the US for a decade. The customization offerings are absolutely brilliant. Currently, lighting options for churches revolve around 2 options: insanely expensive bespoke designs and the same catalouge options that everyone else has... which very often will clash with the existing interior. So being able to offer something that adds touches of personalization to tie into the architecture is novel for just a lighting solution... but building in heating as well... thats a genious stroke. I hope you guys are patent protected because this is insanely good.

IR heating can be great for short occupancy or extremely voluminous locations as shown here but it's far from ideal for homes. Firstly it has to be on continuously for you to feel warm, more importantly, by not heating the fabric of the building, there's a high risk of condensation and mould growth on surfaces in occupied rooms without increased ventilation. It's far from a panacea in homes.

Good to see this. For several years now we have had Herschel infrared panels in our listed house (1550 stone and cob) and love them to bits. Previously we had two wood burning stoves and a couple of ancient storage heaters, but we are much happier now with the quality of heat and the fact that we have been able to move away from burning stuff to heat the house. To complete that picture our energy provider is Ecotricity who source 100% renewable electricity. Initially we ran the panels off programmable thermostats, but we have found we can run them even more economically simply by switching them on and off as needed - as soon as you flip the switch you are feeling warm literally within a couple of minutes.

Great episode Imogen. A perfect application of existing energy upgrades meeting a specific need and being cost affordable while doing so without looking industrial and out of place. I get what you meant about wonderful radiant heat. As a Canadian I can remember many a frigid winter morning sitting in a cold arena to watch my son playing hockey. Some of the buildings used a system where a hanging pipe suspended over the seating area funnelled the heated exhaust of the ice cooling plant to the outside. The heat that they threw off was reflected by curved attached metal "fins" and the effect was like sitting near an old fashioned wood stove. That and a nice coffee and life was good.

For places like homes where you want long term constant heating things that warm the thermal mass like walls etc are better; but for areas like churches, community halls etc which need to be heated quickly but not all the time, such heating is wasteful.

One thing I'm surprised wasn't brought up in the video is the benefit of not having circulating air. Pretty much every method of heating a room involves/requires air flow to work, whether that be convection currents or a blower motor. To make convection currents work, you need to expend a _lot_ of energy in order for the air to move on its own. And of course, this means the heat transfer is very slow, and a lot of it will typically just rise rather than reach the target. With forced air, that's more noise, moving parts, ugly hardware, maintenance, and wasted energy to put the heat where you want it. Forcing air also means the air currents will hit targets that you might not want heated, such as uninsulated exterior surfaces. If the target can be heated directly through radiation, not only do you expend less energy getting the heat to the target, but you lose a lot less heat to the environment.

Oddly, in the last 10 days I've bought two freestanding infrared panel heaters for home. The first was a 540W panel for the north facing kitchen that only has a very small radiator and the gas CH can't get warm enough. It's 600mm x 900mm and sits neatly under a breakfast bar where there was already a plug socket. I thought it would probably also work well in the conservatory so I tried it in both rooms and it worked brilliantly. But it's a bit big for the conservatory (looks wise) so when I spotted a 425W (600mm x 600mm) one at The Range for just £30 I snapped one up. I can't believe how good they are, as the video says they don't directly heat the air, they heat the furnishings and people. Both can be controlled by a phone app and the larger one is even Alexa compatible.

Just thinking outloud here, I wonder if there is still a requirement for some baseload (if you will) of some convection heating (heat pump ideally) . I wonder about the moisture risk longterm if the fabric of certain buildings is never warmed in the same way. Probably fine as it is a massive vapour open duranle ancient building. But certainly for other use cases I think the condensation risk of sole IR heating might need those calcs and assessment maybe. Simon seems like a really interesting chap. Also, were churches heated historically? I imagine some have open fireplaces.

IR heaters are excellent for fast, localised, short duration heating, and beautifully illustrated here in that precise application . But dwelling houses are used long duration occupancy. Furthermore because houses are long occupancy, you also need to control condensation. Aside from ventilation, condensation is also controlled by heating the building up, not just the people in it. You can use IR heaters in this situation, but heat pumps are the more efficient solution for long occupancy times.

Herschel Infrared is the company's name. These chandelier heaters cost between $5650 - $8950 each. It looks like this church bought the most expensive units, so it cost them $35,800 for the 4 units. Probably excluding installation. So long as they remain maintenance free for many years, then sure, these could save the church money over a furnace / boiler system, but wowzers are they expensive up front. If it weren't for the needed aesthetics, then the church could have gone with a much cheaper solution and saw the savings sooner. Have to imagine that the church also installed infrared heating solutions in the other rooms / offices given the replacement of the furnace, so this price is just for the nave.

It's more a question of the level of insulation, if most of your central heat is leaking away, it make sense to heat what matters. This is the extreme case, where there is no question it easier to heat a few bodies in the center than tons of stone, and air up in the rafters. Yes, heat pumps a 3X more efficient, but if that heat is just leaking away through the walls, in rooms no one is in, better to turn on a radiant source where you are.

​@@BooBaddyBig Heat pumps require you to have a wet central heating system i.e. radiators hence the cost of fitting not only the pump itself but also all the piping, radiators, labour etc. can make retrofitting it a really expensive solution. If you have an older 70's property with storage heaters you can half your bill by putting in panels room by room as and when you can afford it. All thermostatically controlled with different times and zones. Heat pumps are great but don't fit every house.

@@eldridgep2 And judging by the lack of enthusiasm in adopting this tech by UK households heat pumps don't fit every wallet either. Rishi has been obliged to up the grant from £5k to £7.5k but as yet no-one can be sure if this "bribe" will work. It should be mentioned too that fitting a heat pump is rather more involved than is stated. Given the o/p temperature of said heat pumps then to get the heat transfer to a living space relies on bigger radiators and possibly increasing the o.d. of the pipework to all 22mm simply to get the heat around the system. Some authorities claim heat pumps work "better" with wet underfloor heating systems as the temperature "match" is closer to the o/p of a heat pump. On top of that is the added faff of increasing the home's insulation. Insulation is probably the most cost effective way to retain heat but not all houses lend themselves to an easy upgrade to the insulation. Heat leaks from "everywhere" and that includes the front and back of terrace houses. Terrace housing generally implies older housing stock and sash windows. Sealing a sash window is certainly doable but not cheap. The old method of packing the gaps with wet newspaper (to more easily get the packing done) works but the natural ventilation is much reduced. Coupled with the 70s/80s trend to rip out old fireplaces and block off the natural ventilation in a room was not ideal as very few people fitted a vent to the chimney breast. The Edwardian house builders knew very well the only way to avoid damp (some older terraces didn't have a damp proof course or relied on slate which cracks over time) was to have air bricks as low as possible and chimneys which would act as both passive and active ventilation depending if the fire was lit or not. Fitting a gas fire in the old fireplace, without ventilation around the fire merely allowed the water vapour produced by the gas burning to rise up and then condense in the upper parts of the flue. Which merely allowed damp to penetrate the brick work causing the plaster in the bedrooms to fall off in time. All the above available via Google if arsed.

Infrared/direct heating is great for applications like a church or a garage but im not sure I"d use it for a house. Its fine if you sit in front or under the heater but if you want to heat a whole house the electricity is one of the most expensive methods. In the UK ekectricity has typically cost three times mains gas.

I think that is the whole point @ColinWatters. IR is used to heat people and articles in just a small area as opposed to the whole structure and components within it. Paired with a heat pump system, which is much more efficient that just about any fossil fuelled burning system, and electricity is bound to be more economical. And of course you could opt to generate some of your own electricity if you wanted to.

Really elegant solution. I'm curious where the crossover is, based on the type of space you're trying to heat and the use case, where a heat pump vs zonal IR heaters will be better and vice versa. It's interesting that they expected electric to simply cost more than the gas heater, so I wonder how the economics would have worked out with a heat pump vs a zonal floor heater instead if they could have ignored the planning and heritage requirements.

iirc presuming a COP of ~3+, heat-pumps work out roughly even with Gas, at current electricity prices... so if this radiant heater is cheaper than a gas heater, it likely would have been cheaper than a heat-pump too. Basic meth would support this hypothesis too - a heat-pump would nominally use only 1/3 of the energy to produce the same heat - but if the radiant heater is able to heat less than 1/3 of the building interior, then it will use less energy overall than a heat-pump (because a heat-pump cannot effectively heat only part of a room)

Could more information be provided on how Herschel heat their manufacturing facility? Like countless others, my shop is a 10,000 ft² steel building with a 20' roof at the ridge. We absolutely blow through copious amounts of fossil gas attempting to heat the building during the cold months. The existing lighting are metal halide bulbs. They're slow to light and are tremendously wasteful; rated at 400W, but actually consuming just north of 450W of electricity. With 13 fixtures, the energy just to light the warehouse/shop area comes to about 1.2kWh per month! The replacement LED fixtures I'm about to fit will cut the lighting component of the energy bill almost in half. They'll also be brighter, light instantly and produce no heat (which only serves to increase the temperature in the warehouse/shop during the warm months). It seems that infrared heating, combined with LED lighting, would be a natural fit for a quite large target addressable market.

For most spaces the cost effective solution is insulation, just spray foam the roof and walls. Where radiant makes sense in big space is a shop where the doors are constantly open in cold weather. And even then one of those see-through flap doors between receiving and the shop floor might make the biggest difference?
@ARepublicIfYouCanKeepIt
@ARepublicIfYouCanKeepIt 5 ай бұрын
@@briankuhl9314 Not true. My shop is fully insulated. The problem is conduction. Heat energy migrates from hot (interior) to cold (exterior). This heat loss is further compounded due to the volume to be conditioned. The vast majority of the volume doesn't need to be conditioned as it's entirely void of either people or material. Infrared heating works by heating people, not objects. Therefore it'd be superior to forced hot air. Especially where the electricity was sourced from renewables. Lastly, spray foam insulation in buildings such as steel warehouses is economically infeasible.

Of course heating just when and where you want the heat, when that reduce the amount of heating required to a small fraction of heating up the entire building can save a lot of energy. In most cases you want to keep a reasonable temperature, constantly, or at least for prolonged periods of time. While very a cost efficient way to provide thermal comfort temporarily and locally, with little energy, infrared heating with resistive heaters shouldn't be mistaken for a generally energy efficient way to provide heat, it is just not that. A lot of advantages in that specific type of scenario, and similar situations. Instant heat radiation, localized, and also cheap, robust and compact equipment, without moving parts, are readily available. The "COP" being 1 isn't a huge drawback when you just need to achieve thermal comfort in a part of a huge stone building for fully clothed people a few hours a week, and only part of the year.
