Ahmad: please get in touch with Markus Falkvall and speak to him about helping you out.

Reto Hummelshøj 

Thank-you all :-)

Ahmad Arabkoohsar 

Is there any where I can find DHW draw off pattenrs?

Petter Duvander 

Aleksandrs: Rolf says there will be information on the Cool DH web site. www.cooldh.eu

Aleksandrs Zajacs 

Where it is possible ti find an information regarding decentralised energy source

Reto Hummelshøj 

Do you recomend to supply heat by floor heating or low temp radiors and why

Aleksandrs Zajacs 

Q: Do you have marekt ready solutions for integration of local (decentralised) thermal energy production units into existing DH systems? For examle feed in systems from solar thermal?

Ahmad Arabkoohsar 

Thanks

Ahmad Arabkoohsar 

Markus, thanks for the answers, I am running a project on DH systems in Denmark, can you give me your email address?

David Huber 

Ok thanks a lot.

Markus Falkvall 

Ahmad - the pressure rating of DH grids is often 16 bar which is usually not compatible with plastic pipes. At least not for the large dimensions required.

josh buck 

Is there an impact on heat delivery temperature from providing these heat recovery pipes within the 65oC DHN pipework casing?

David Huber 

Is it possible to estimate how large the share of the solar yield is in relation to the recovered energy?

Ahmad Arabkoohsar 

As we can have plasticpipes for lower temperatures, why Logstor had not used plastic pipes for return line s (at 40 C) so far?

Reto Hummelshøj 

Could the heat recovery pipes be used by other consumers having heat pumps?

Ahmad Arabkoohsar 

I mean what portion goes to insulation, what to casing, what to media-pipe, etc.?

Ahmad Arabkoohsar 

Thanks for the presentation, Is there any estimation of what portion of the cost of the pipe is associated with the media pipe?

Reto Hummelshøj 

What is the extra cost roughly for adding recovery pipes to achieve "zero energy loss" pipes

Reto Hummelshøj 

When will electro fusion welding connections be available?

Reto Hummelshøj 

What is the lambda improvement with the new foam, and are there other advantages of using it?

Markus Falkvall 

Sorry about that. :) To answer the questions about Legionella: the problem is not Legionella in the distribution pipes but rather in the secondary systems (at the consumers) where you might get stagnant water and require at least 50 degrees in order to both clear the system of bacteria but also to meet the requrements from swedish law.

Petter Duvander 

Markus forgot to repeat a couple of your questions, I hope you could decipher when they were answered. =)

Ahmad Arabkoohsar 

Legionella in pipeline is not a problem as water is moving and not stationary, right? Then, why are you worried of legionella?

Ahmad Arabkoohsar 

2: How much (%) plastic pipes save compared to steel pipes?

David Huber 

Why do you have problems with legioneal when heat exchangers are used at the energy transfer station anyway.

Ahmad Arabkoohsar 

Hi, Thanks for the informative webinar. I have some questions: 1: what is the rate of losses you get from conventiona system and LTDH system?

Edith Haslinger 

Could you please repeat which is your backup-heating system, when MAX IV cannot supply heat?

Reto Hummelshøj 

What is MAXIV doing and what is the cooling used for - and capacity of the system

Petter Duvander 

Please write your questions here during the talks, each speaker will reply at the end of their talk.
