Ah! Sound down pipes from other rooms! Rearly hear it but live in a quiet area. No. Not for us. Wife says no noise unless on boost and then only a low hum with ours far far quieter than the fridge Freezer!! Toothbrush charging makes more noise! HOWEVER we followed the installation instructions to the letter. Our unit is 2 meters from the bedrooms above the ceiling. Wife is noise sensitive!

Hi @Si3 It's different than before we had one. No trickle vents. An almost unobservable flow of fresh air. Sometimes noise travels down the rigid ducts.The boost function clears the air. Never hear the MVHR at normal speed. Air temprature outside this morning 1.7C. Fresh air temprature entering living room after heat recovery, 15C. Definetly keeps the place warmer in the winter. Sometimes feels dryer but we only have 100m2 floor and the humidity from showering seems to compensate even though we have automatic humidity sensors that boost the MVHR. Cooking can be a challenge if you don't boost the system enough when cooking as the smells can linger. Even in the summer we now leave the MVHR on to avoid any problems with the pipes. Usually look at the filters once or twice a year. It has been a tricky process because we retro fitted the the system and had to super insulate the ducts in the exposed loft. Good luck M

+1 on both worth it and that its harder to do later. We have 100m2 floor area and our MVHR runs at 17 Watts normal and 25 Watts on boost, so it would cost us £40-45 a year to run but we have PV so even less..... That's 45 pence per year per m2 flooring.

+1

Thanks for the info @Iceverge. It would be nice to have it broken down to cost per m2 so I can relate that to my home, and probably others would too. How many m2 was this over?

If your planning to stay in your new home for years and years then the thicker the better. We have about 200mm but in a timber suspended floor. AND if your are going to have UFH the thicker the better. Good luck M

Well the combo is coming together and my wife insists that I make the controls as clear as possible "in case your not here". I wondering what she means. Still a lot to do though..

Hi @SteamyTea Thank you for your trials, but not so fast. I cannot understand your conclusion. Surely the 242080 Watts: (Notice I'm now using the capital W in Watts...) used in the test used less energy than the other alternatives (although it took longer which was not part of the problem.) But even so, is there not a scientific calculation that will identify what the answer should be? When the induction ring is fully energised, is the energy all used up producing and electromagnetic field, and therefore no more, or less, energy is used when heating the pan? Someone must know the scientific answer.

I think there are too many variables for this to qualify as an answer to the question.

I suppose the question is: When the induction ring is fully energised, is the energy all used up producing and electromagnetic field? And therefore no more, or less, energy is used when heating the pan?

There are two views about what happens when you use a large induction ring and a smaller pan. Assuming everything is equal and the pan is large enough to turn the ring on. Will the ring use the same amount of electricity if it was a large pan or a small pan. I.e. as the pan does not cover the entire ring, will the same amount of electricity be used even though the whole ring is not covered. Whilst it seem easy to answer I have found many conflicting opinions.

A kW per what? Is that a Cornish idiom?

What are you using as the most extreme cold weather? -5C outside??

Remember the nearer the temperature of the water compared with the outside air, the more efficient an ASHP runs. So ASHP works on "low n slow" So the more surface of emitter the lower the water temperature needs to be to meet the same temperature. Hence the increase in radiator sizes if swapping form Boiler to ASHP.

Correct

Not sure that's rubber.. looks like PVC to me, unless its well oiled

+1 same location. Same result.

Well, I fear that it has the potential to go over the threshold of the maximum allowable, and therefore you need to apply to the DNO before connecting to the mains. Although my inverter could supply 6kW - my panels only 5.12kW, and the CT clamp system would restrict it to below the limit, the DNO still assessed the system by the inverter maximum output. This being said I can only comment about my experience with Scottish and Southern Electricity DNO. M

@Buffs, what is the kW rating of the inverter you are using?

The only reason I ask is because a previous client was informed that they weren't allowed 2 front doors due to planning.... Marvin

Does that mean 2 front doors?

The smaller the U-value the more thermal resistant.

Yes. Hense the higher the power to energise the hotter it gets. ..

My CTA (chartered tax accountant) says you need everything going to the address including council tax and all mail for at least 6 months but best for a year if you want to avoid HMRC challenging it. Your warned. Best advice is to seek advice from a CTA covering all your circumstances! Good luck M
