If I have my main, say 300L HP / PV / Solar Thermal tank in my plant room (or my (formerly) airing cupboard) what pipework do I need to run from my A/GSHP installation to the 3 Mini Stores above my 2 en-suite & main bathroom showers? An example system diagram would be helpful please in the Newark pdf spec.
I listening your hula-hop you have no ideal what is heat thermalagy, and trying to give a stupid advice to others. When you talking about temperatur everyting in that room must be the same temperature it will equal out you can't do nothing about it. Put a glass of cold water on the table you will see it will become the same temperatur, the question is you will let the tempeture equalize and put on 1-3 degree heat lost or you will be a bone head let 50% of the lost when you lower the temperature. Ask a master plumber.
Clever idea will plumber be able to access pipes in a kitchen cupboard it will be a tight squeeze 😊😊 in my opinion keep it separate from kitchen cupboard.
Are there any thoughts of releasing a smaller diameter cylinder in this design? I have a tall 1.8m cupboard where the combi boiler is located, but the cupboards are only 40cm deep
Not as a stainless steel Mini Store, but we'd be able to potentially manufacturer a copper equivalent with a 400mm overall diameter, if you can provide and guarantee the exact design. If this is of interest to you, please feel free to contact our sales team to discuss.
That's great @heatgeek Adam, very clever design. Please can you tell us the minimum required heat input to maintain a constant shower temp with a flow of 8.5L/min as per the video? Can a smaller (e.g, 5kW) ASHP deliver this in winter? Many larger properties with large heat pumps may well have room for a DHW cylinder, so it's more likely to be smaller properties with smaller output ASHPs where such a solution is more likely required, but if it requires a larger output heat pump to maintain water temp then that kind of defeats the purpose. Perhaps that's an experiment you could run in winter?
Could such a tank not be built into a heat pump itself then? Or put insulated outside? I guess like others have said though - a good use for kitchen corner units that at a PITA to get pans and things out of anyways.
Is it more advantageous to include a buffer tank in a scenario where only underfloor heating is used with a heat pump? The power output of the heat pump is specifically matched to the requirements of the underfloor heating system (so it's not 1/3 or 1/2 od the heatpump power output).
No i leave mine turned off , and I do actually pay much much less. Its not our fault yoy the industry invent products and add on products and insulation . I'm not leaving heating on all the time, that's just dumb, and I did it my way, hee hee boom Yes I do pay less , way less . There is no need at all to leave a heater on all day , that's silly I don't even have heating on at night . I got sick and tired of paying big bills and I'm not doing it anymore , simple as that I'm not So I turned it off and kept it off , and my bills dropped big time , I'm sick of throwing money away to these companies , so I took matters into my own hands . Mine is off I would say for Jan to November ish. Yes I'm serious , I boil water in kettle for sink , works just fine . So my wages and money is staying in my bank, not leaving my bank, and I'm saving a hell of a lot money . I bet most are spaying crazy bills , NOT ME I'm not following like sheep ,
What would provide more accessibility to people who don't consume this much, is to design smart meters with several kwh battery pack docks to use with bikes. This way range issues for ebikes could be largely nullified as its much less of an issue swapping out standardised ebike battery's. ebikes require a fraction of the energy cars do for journeys, many of which would be no less convenient or else more convenient or faster around built up areas. If well adopted the amount of energy needed for many day to day journeys would be reduced to such and extent that all these material issues we hear with electrification of transport would be significantly reduced.
Depends on your vehicle. Is it V2L, V2H or V2G or none of these. When you watch the politicians saying if you want to save money. Help support the grid etc. they don't even mention that your car may have no ability to do anything of the sort. Or that you are one of the many that can't park at home or are not allowed to charge in your shared building. And then you have the ever present worry as you put your car under load with bidirectional power that the bloody thing will go up in a ball of flame and take your house with it. If you must drive one park it in the middle of nowhere to minimize the risk to others.
@@davetaylor4741 Literally first response on Google from Tusker a car fleet manager: “With data corroborated from a US insurer, the study found that EVs suffer 25 fires per 100,000 sold. Petrol or diesel vehicles were found to experience 1,530 fires per 100,000, with hybrid vehicles at a notably higher risk of 3,475 fires per 100,000.”
@@davetaylor4741 Literally the first search results show 25 per 100,000 for EVs and more than 1500 for ICE cars. Hybrid cars are twice as bad again than standard ICE cars.
Two interesting things happen when you combine EV and household heat pumps. . Energy savings by switching to heat pump are greater than energy requirements for average driving. Net energy reduction. . Typical heat pump power consumption (~ 1-2kW) is generally within the capability of many EV V2L capabilities. Lookup the Australian HOEM system
Was there a follow up to this? Most interesting though. So, if you lived in a humid place (and island for example) an air to air would have a defintive advantage as it would save you needing a dedicated dehumidifier (or at least reduce the amount you need to use it) correct?
I don't follow your argument, with the attics air supply essentially isolated from the rooms below being supplied via the now required roofspace ventilation it should be employing external air.
I'm still not convinced, for all sorts of reasons. I think a lot of your underlying reasoning is badly flawed. Furthermore, the incredibly low adoption rate of heat pumps & clever water cylinders by The Great British Public (this despite the availability of very generous grants) suggests to me that they too aren't swayed by these syrupy sweet arguments either. I could say more on the self-evident, 4:1 price differential between electricity & domestic gas. I could mention the eye watering upfront costs of these systems versus the alternative of spending zip, nada, nichts in continuing to use your existing boiler. I could highlight the fact that for the near future, a goodly proportion of the UK's power is still going to come from burning gas (especially in winter when demand is at its peak) so is far from 'clean'. But I'm going to pass on all that to highlight one thing. In 2023, the UK's entire emissions of carbon dioxide (+ equivalents) from all sources was 338.5 million tonnes. That's a paltry 0.8% of the global total. The equivalent 2023 number for China alone was 12,603.5 million tonnes or 31.2% of the global total. Furthermore, this number was a 708.0 million tonne INCREASE over the 11,895.5 million tonnes they emitted in 2022. That's an ANNUAL increase of TWICE our entire output from all sources. And it's not just China either. India's sizable carbon dioxide emissions went up by an even faster rate of 9% between 2022 & 2023! As a nation, we are deluding ourselves that us committing vast amount of personal upfront capital to changing ourselves is going to stop global warming from advancing at an alarming rate. We are simply too insignificant.
I’ve got an air to air in my bedroom, wall mounted unit. Simple to use, it has silent mode for nights (around 30DB) and it runs slowly with minimal cycles. Then can choose between low, medium and fast for when it’s hotter or the sun is on my room. Then it has High power mode which is 30 mins of all systems running at full wack. It’s an inverter unit with outdoor temp settings. Getting a COP of 3.8 on cooling according to its stats. I’m not even an engineer just interested in the best way to use it. Most units move the louvers to the best setting by standard these days. Good video gents.
I would be interested in what research has been done to help get as much warm air into the heat pump rather than just take normal air. By this I mean possibly siting the heat pump in a warmer area in sun. If there was an ventilation system installed in a house that had exhausts to the outside air without any heat exchanger would there be a benefit in funneling the waste air/heat from the house towards or into the main intake of the heat pump? Would it impact the SCOP at all?
This video could be a life saver as this issue is driving me crazy! Just got a new Worcester Greenstar 4000 30KW combi boiler. This was fitted with an ESI ESRTP4RF+ wireless thermostat. Temperatures can fluctuate up to 2 degrees oC above and below the target temperature and device is slow to react to room heat changes. I'm either freezing cold or boiling hot! Can this boiler use modulation and which thermostat would you recommend, please? (Sorry if you've already mentioned this model, but there are 100s of comments to search through!). Property wise, it's a 3 bedroom, terrace house, outside walls are more east / west than north / south. Thank you.
Is your unit an inverter though? I’ve got a 12,000 btu DC inverter system, runs at 34db on quiet mode and similar with the outside unit. It’s very good at holding a steady temp. I had fluctuations with a standard unit before.
Are the radiators normal cast iron radiators? Could you please share the manufacture of the radiators so that we can compare the specs with standard radiators? Would this heat pump system work with UFH on the ground floor and cast iron radiators on the upper floors?
The timing for the looming collapse has just accelerated now that Trumps going to win according to all the polls trumps chances to win just jumped to 70÷ percent since the shooting . Less restrictions on pollution and toxins in water means more money for the richest oil and gas companies means cheaper gas prices means more usage = more co2 = more heating = more weather related disasters. Right now half way though the year the USA had 50 billon dollors worth of disasters
I have brought the same idea from Telford cylinders for years, KIWA and Wras stoped this cylinder due to first 1 litre of water doesn't get heated and may cause legionnaires, glad you have got round this with WRAS, good job 🎉😊
You are stuck in outdated technology. The combi boiler does not require water tank. Why the UK go backwards. Other countries use the electric boilers in the last 50 years. Most of the houses in the UK are not designed for water tanks. The Net Zero is the biggest scam in the UK. Expensive to buy and install complex and expensive to maintain, plus need a lot of space. Reinventing the wheel bring us nowhere. With your product you just add more electricity consumption.
I bought a set of 3 for my last house. Put them on a 1200 x 600 K2. Getting a heat pump in my new house so interested to know how much these improve the output of a radiator. Can I just compare the temp difference across the radiator before and after installing them to work this out? Let me know if you want results. Set of 3 is approx £100, and might be cheaper than upgrading radiator sizes in some cases or may limit your overall upgrade costs.
Air to Air inverter heat pumps do not suffer from the pump switching on and off noise change and they make much less noise when not running at full power.
