Thanks for watching TC! 👍

Hi Brian next time will do all the best Tony 👍

Many thanks Marty, always important to move with the times and continually develop our skills. Take care 👍

It doesn't perform as well as a standard kitchen extractor that vents outside. This is for constant background venitlation 95% of the time and boost when using the shower or cooking. The extractor point in the kitchen isn't recommend near the hob because of the grease might get sucked up.

Your kitchen extractor directly above your hob/stove has a few speed settings 1/2/3. It will extract from 10l/s - 24l/s. Many kitchen extract systems above the hobs do not have the ductwork installed to dump the air outside the property. Its simply pulls the air pass a filter and dumps it towards the top of the kitchen merely acting as a degreaser. Kitchen extraction that is part of the mechanical ventilation system (MVHR) is more consistent and reliable. The air valve in the kitchen ceiling can be setup in a manner where by the air is extracted 24 hours a day @ 10l/s like setting 1 on the independent kitchen hob noisy extractor. You do not have to keep turning it off and on. If you require more extraction rate from the system your could flick a boost switch and the air extraction rate can increase from 10l/s to 17l/s. The boost could have an overrun timer on it set to 15 minutes where you control the rate of air you removing.

@@kirkenicker3136 OK. But the area of the air attraction unit is too small to really extract the air from a large kitchen even at 10l/s. The normal formula is 1l/s is approx 3.6m3/hour. So at 10l/s that is 36m3/hour of air extracted. This would be fine if the volume of the kitchen is small but not sure you will get many air changes/extraction per hour with such a system. Therefore my own conclusion is that a good hob extraction can achieve a much higher volume of extraction and more air changes per hour.

asif zardari residents don’t stand in front of hobs for hours on end to ensure living spaces undergo sufficient air changes. I have been commissioning residential ventilation systems for 9 years now and can tell you 1st hand that people will never remind themselves to run jobs that are a noise disturbance for long periods of time.

@@kirkenicker3136 you make a valid point. I still think these systems are good for general background ventilation as they are less noisy and run for long periods. Maybe i need to test it out when cooking a spicey Indian curry to see how well it works compared with a good kitchen extractor to a duct outside.

Hi John yes it should do just make sure you talk to architect and design team of the system all the best Tony 👍

@@BuildWithAE No bother Tony Thanks

Hi Elliott thanks for your kind words hopefully one day we are glad you are enjoying the channel all the best Tony 👍

Great content

@@BuildWithAE last time I went to the A and E I was supervised by a so called “enemy" that had to make sure I was receiving the care I needed, after he diagnosed me with my list of problems by looking at my face I decided to go private.

Bad robot? Lol

@@Dragon-Slay3r I know it's a fun icon

Hi Jamie it’s six years with the system and grant we put in but the other main question is the quality of air especially if you are asthmatic or hay fever no mould build up, there’s one gentleman on this feed had done his house for £1400.00 because he lived by a main rd all the best Tony 👍 have a awesome week

Glad you like it Stephen! Take care 👍

The example in the video is for a very large house. I have a 3 bed terrace 92sqm floor area. I installed 1 unit, 100m of ducting and it cost £1300 but I done all myself. I also have underfloor heating on the ground floor and rads upstairs. The hot water has nothing to do with the system. He did say they have ufh in the kitchen..

Hi David this house would normally cost Thousands of pounds to run a year. The HRVS system with the Air source heat running the hot water and heating side this pay back will be in 6 years with the grant from the government, Fossil fuels just keep going up. it has massive health benefits for Air quality and filters out irritants like pollen and pollution which is good for hay fever and asthma sufferers all the best Tony 👍

@@AlexSavage hi Alex, I've contacted a couple of firms for quotations but haven't had any response, I'd like to fit mine myself too, where did you get your kit from? Did you get it designed?

@@THE-AIDEN-PROJECT when you buy kit from firms they will do the design for you as well, if you want to go on the DIY route there's a lot on info on BuildHub forum under Mechanical Ventilation with Heat Recovery. It's definitely doable, it just depends how hands on are you.. I got my unit on ebay for a bargain price and I done the design myself.. after spending lots of hours online researching.. good luck!

@@AlexSavage yeah I'm a super DIY'er! 😂 I don't have a trade but I'll have a bloody good go! You'd tell that from my channel but I've had to go ghost mode until I sort abit of a nightmare out. I'll check the forum out, cheers mate

No chance. Keep on with gas

You are asking is you can trade apples for aubergines. A boilet gives you heat, a mvhr doesn't, it only recovers heat through ventilation.

@@AlexSavage that makes my blood boil

Yes

Only times you may need to reduce fan speed is in extreme low temperatures to stop ice problems. Not something we have issues with often here.

Most units have frost protection. Some will let you set the temperature that it kicks in usually -3 -5

🤑🤑🤑+ labour 🤑💥🤑💥🤑💥🤑💥😝😝

A lot.

Machines are about £3k each, there’s not a lot too them.. ducting is cheap It’s the upheaval and retrofit that’s makes it expensive, you also need space for all those pipes. New build, it’s not that expensive.

Units are a lot less than 3k. I done my whole house for 1.3k, 3bed terrace retrofit DIY. This includes unit, pipework and vents.

@@martin2466 my unit's yearly consumption is less than £100 and I need to change the filters twice a year, that's another £24 a year. So, not that expensive taking into consideration the heat recovery

It doesn't cost too much if you go down the DIY route. 3 bed terrace cost me £1300.

Hi Steve absolutely he is a awesome guy really cool channel there are so many really cool guys and Ladies on KZfaq and Instagram all the best Tony 👍

It was on the design no other way

The paid sponsorship didn't come through Airflow on this video, it comes from our show sponsor (MKM) that appears at the end of every episode. Take care 👍

@@BuildWithAE I understand, I like that you are spreading the word about MVHRs but no so keen when you focus o a particular brand. Keep up the good work!

Hi Alex thanks for your kind support and help answering the comments it would be cool to have you on a podcast if that’s ok with you and we can talk about different makes and other factors with the systems all the best Tony 👍

Ha, ha.......tough crowd!
