You do realize that facts make you look like a fool? COP's.pdf

Not clear cut info, it refers only to noise. Generally permitted but with limitations, I don't know about enforceability. Noise requirements for heat pumps and air conditioners are being tightened News item | 23-03-2021 | 11:13 As of April 1, 2021, new noise requirements will be imposed on (newly placed) installations for heat or cold generation installed outside. This concerns heat pumps and air conditioners that are used in homes and residential buildings. These installations may not cause more than 40 dB noise to the neighbours. With this national noise standard, neighbors are better protected against noise from heat pumps and the development of quieter heat pumps is promoted. The heat pump market shows continued strong growth in numbers and in heat production. This noise requirement will help the heat pump in its further advance, and also accelerate the development of new quieter heat pumps. Sales are expected to continue to grow in the near future. The determination method for the new noise requirements has been laid down in the 2012 Building Decree Regulation (Government Gazette 2020, 62676), which will enter into force at the same time. This determination method is a noise measurement on location. However, on the basis of acoustic calculations, it can be made plausible in advance that the noise requirement will be met. The Ministry of the Interior and Kingdom Relations has commissioned a calculation tool (ODS file) and an associated manual for these calculations. The noise requirements do not apply to the heat pump itself (from the factory), but to an installation placed near a home. The heat pump itself generally does not meet the 40 dB requirement. This means that the installation must be placed at a sufficient distance from the neighbors or must be shielded so that the 40dB is not exceeded. The National Government. For the Netherlands This is just for laughs

To participate in the conversation. There will be cases when a HP AW/AA will impact the neighbors in the summer, and there will be cases when not. It's all about space and location. This is a HP that was moved and encased in metal, from next to the house wall initial location, opposite a neighbor's brick wall that was reverberating the noise, affecting both parties, more the owner due to the location outside his home office. There can be solutions, although not for every case. Photos from a dutch forum.

I was only addressing the non fact that they run flat out in the summer on DHW duty cycle.

Most actually don't run flat out at all. If you have a look at those shared on https://heatpumpmonitor.org/ you can see that even now at 10-15 Celsius they don't run flat out. Even less in the summer due to higher air temperature the compressor uses less energy/workload to achieve the same output. Just check these things before saying it that it's that plain simple.

It works only when you think of it as a great solution, but in practice you cannot cover heat requirement with an exhaust air heat pump, you will eventually need that extra source of heat.

have you tried any of the hp installers with youtube presence? Urban Plumbers, Dore Woodman

do you have the data book? https://www.irishellas.com/files/Engineering-Product-Data-Book_Monobloc_Gen.2-R32,50Hz-_MFL66101126_5BPM5-01C-Mar.2022-.pdf https://gathering.tweakers.net/forum/list_messages/2017448/last 80 pages of dutch user experience, click right/translate english, top search "minimum"

Air source cylinders do not have enough power to supply the energy required for hot water and heating.

thermopro tp25, I know the probes are for meat but I don't see they cannot be modified/replaced/thinker with.

Are you able now to solve/clear the issue with a blocked filter and the subsequent error code yourself?

In your situation with a start temp of 6, I would try to divert part of the heating residual so it commutes less when it's usually commuting. I would even have a second DHW buffer with 50% space for water and 50% taken by a big coil for heating diversion for the same purpose, less commuting. With the benefits of pre heating the 6 degrees water to LWT for heating. Now in a passive house might not be that drastic the commuting. But a general idea for the one case that it would fit their needs.

Q = m * c * ΔT = 300 kg * 4.184 J/g°C * 42°C = 52,718.4 kJ 52,718.4 kJ/3600=14.644kW=3Hours

If I were you, I would go back to sleep and dream for a top fan heat pump, check RED heat pumps.

If in the space where the heat store is placed is too cold, you don't need a radiator, you need to insulate the space so you don't loose heat, rather than waste even more.

we need the sound recording with the same device to see the difference - well done

I'm struggling to understand how you got there, it looks more like Jeremy Clarkson going off the tracks whilst field drilling.

@markharro Put multiple tubes of 1cm interior diameter with the entrance at the base of the walls under the skirting, and later you will put any temp probes you find suitable for your system. I don't think slab humidity sensor is something that you need to worry(I've just changed my mind) For kitchen/bath I would put humidity probes in the grout joint for leak detection, and now for condensate from cooling, but really you need a way to manage the temp to avoid condensation rather than sensing when it happens

With fans

Use the higher temp return as a flow for the lower temp

I wonder why the heat pump is the issue in this equation.

The heating company should not retrain any of their staff and not take any customer money until two of their leading heating engineers should design a heating system to either their home or work place to which they can attach any heat pump on the market, and then check how the heating system should function so that it distributes the heat from the heat pump efficiently. As long a the heat pump as a product doesn't have any defects that makes it not meet the specs, the heating distribution system is the only part that matters, which a heating engineer according to their qualified experience will either fail or make it a success. To have a heating engineer not achieve the requirements of a system to move heated water around a system efficiently has nothing to do with the heat pump. Examples are UrbanPlumbers and AllenHart999, two boiler engineers installing HP successfully. I wonder why some can do a proper job and some not.

context context context "Like Bosch, gas industry chiefs are backing hydrogen as a long-term solution to heating homes. Industry representatives wrote a joint letter to the House of Lords committee that published February's report on hydrogen, arguing that heat pumps will be "unviable" for millions of low-income households, high-rise flat residents and those in small properties." All Worcester Bosch boilers are already hydrogen-blend ready. That means they can run on a blend of 80% natural gas and 20% hydrogen, ready for when the government begins to add hydrogen to the UK gas grid.
